I am trying to use the 64 bit rxtx serial communication library (downloaded from cloudhopper) with 64bit windows 7 and eclipse. I get the message:
java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path. The dlls are in the /jre/lib dir as well as the Windows/System32. The RXTXcomm.jar is in the build path for eclipse as well as in the jre/lib/ext dir. I ran process monitor in the background and and see that RXTXcomm.jar, rxtxSerial.dll, and rxtxParallel.dll are all found and have been opened, So I am unclear as to why this problem is occurring.
Any suggestions.
Go to Project -> properties -> Java build path ->Find your .jar.
Click on + to open the JAR's properties.
Select Native library location and edit it to point to RXTX's shared library (.DLL, .so, .dylib).
You can install librxtx-java package from repo for Ubuntu.
You can also add a virtual machine argument:
-Djava.library.path=c:\path\to\dll\
or
-Djava.library.path=/path/to/lib/
That worked for me. Also refer to this question.
Windows user : my problem was actually that I was placing the rxtxSerial.dll and the rxtxParallel.dll files in the wrong directory.
In my case, they were in [...]/jdk1.7.0_09/bin/ instead of [...]/jre7/bin/, although paths may differ for different versions of Java.
After all it's logic, if we want our JAR to run outside our IDE, we must have the dlls in our java running environment, not in our development environment :)
I resolve this problem by adding rxtxSerial.dll[jre 1.8.0_45/bin] and RxTxcomm.jar[jre 1.8.0_45/lib/ext]
Hy, I had the same problem when integrating the RXTXcomm into Netbeans under Ubuntu 11.10.
I am guessing that you are not copying the files in the right place, at least that was my problem.
Under Ubuntu java is installed under usr/lib/jvm. BUT here I had a lot of forders (ex java-7-openjdk-i386, java-7-common, java-6-openjdk ...). In Netbeans I check what is the path of the JDK included into the project, it was java-7-openjdk-i386 . so I took the rxtxSerial.so (under windows it is rxtxSerial.dll) and copied it to java-7-openjdk-i386/jre/bin and it worked like a charm .
I hope this helps.
I was having the same problem even after installing the RXTXcomm.jar in the Java\jdk\lib directory. Based on the instructions at http://www.jcontrol.org/download/readme_rxtx_en.html
I located the rxtxSerial.dll and the rxtxParallel.dll files. Placing them in the bin directory did not help, but placing them in the lib directory along with the RXTXcomm.jar solved the problem.
I had the same problem. So I installed JDK 32-bit and added those RxTx files(x86) to Program files(x86)/java/... folder instead of Program files/java... folder. Also I added those RxTx .dll files(x86) to /System32 folder. After that the problem was resolved in my application.
FIXED:
when using IDE such Netbeans it has it's own directory for the JRE, were you probably installed your RXTX drivers, but when running the JAR file outside your IDE this error occurs...
Solution is install the RXTX drivers also inside the JAVA JRE directory which use to run all your JAR files.
Under Netbeans 5.5 on Windows, I needed to right-click Libraries under
Projects on the left hand side of the screen, and select "Add
JAR/Folder", picking the RXTXcomm.jar file. Only then did my
enter code here
become a valid command.
Also, I got a run-time error where it failed to load the
rxtxSerial.DLL library because it couldn't find it. I needed to
right-click the project name, select properties, select Run under
categories, and add a VM Options: entry of
-Djava.library.path="C:\where-ever-you-stuck-rxtxSerial.DLL-file;%PATH%
Example:
-Djava.library.path="C:\rxtx-2.1-7-bins-r2\Windows\i368-mingw32\;%PATH%"
While I'm sure there is more than one way of adding the directory to
your path, this worked for me. Note I did the default NetBeans 5.5/JDK
1.6.0 isntall accepting all the default options(ie clicking next until I got to finish), so I haven't modified my java paths or anything.
Alternatively you can copy the *.dll into C:\Windows\System32\, Java
will find it there automatically.
Note that you cannot use the 32bit DLL when running a 64bit JRE:
You will get an error similar to:
Can't load IA 32-bit .dll on a AMD 64-bit platform thrown while loading gnu.io.RXTXCommDriver
To solve this simply install the 32bit JDK and add a new Platform in
Netbeans under Tools->Java Platforms->Add Platform and change the
project settings to use the newly created platform. make sure you type
"import gnu.io.*"
from http://rxtx.qbang.org/wiki/index.php/Using_RXTX_In_NetBeans
I had the same issue, on windows 10 and eclipse, the probelm was i had java for 32 and 64 bits, so i installed RXTX library for 64 bits but eclipse was using the 32 bits java enviroment, so what i did was download RXTX for 32 bits copy the necessary files to C:ProgramFilesx86/JAVA_HOME as in the instructions for RXTX and the problem was solved. Hope this helps anyone.
I had same problem. I was trying to run built jar file from dist folder and it was not working even it was working from NetBeans IDE. I copied rxtxSerial.dll file in dist folder where my main jar file was and it started working fine.
I was having this error before:
java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while
loading gnu.io.RXTXCommDriver

I am trying to setup a Java project on a Windows computer that invokes R code using rJava/JRI. I have installed JDK 1.8, R 3.5.3 and rJava library in R on my computer. I have added the following to my Pathvariable: D:\Program Files\R\R-3.5.3\bin\x64; D:\Program Files\R\R-3.5.3\library\rJava\jri\x64. I have also configured the Build Path in Eclipse by adding the three JAR files from the jri folder as external JARs and by changing the native library to D:/Program Files/R/R-3.5.3/library/rJava/jri/x64. These are the same steps that I've recently done on another Windows computer and afterwards the R test script worked perfectly. However, on my current computer I keep getting the following message:
Please make sure that the JRI native library is in a directory listed in java.library.path.
java.lang.UnsatisfiedLinkError: D:\Program Files\R\R-3.5.3\library\rJava\jri\x64\jri.dll: Can't find dependent libraries

Any idea what's going wrong? I would be really greatful for any help.
EDIT: Here is what my Build Path looks like:
EDIT2: Additionally, I have now copied all .DLL files from D:\Program Files\R\R-3.5.3\bin\x64 together with jri.dll to D:\Program Files\Java\jdk1.8.0_201\bin as recommended here. Still no luck.
Please try this one:
Run As -> Run Configuration -> Set Environment Variables ->New
Name : PATH
Value: C:\Program Files\R\R-3.6.1\bin\x64;C:\Users\[Username]\Documents\R\win-library\3.6\rJava\jri\x64;
Ok, I got it. After having done everything that is listed in the first post, I also copied all .DLL files from D:\Program Files\R\R-3.5.3\bin\x64 together with jri.dll from D:\Program Files\R\R-3.5.3\library\rJava\jri\x64 to D:\Program Files\Java\jre1.8.0_201\bin (in addition to the JDK folder). Now the test script works. Thanks to everyone who tried to help!
Try this:
Right click on project > Java Build Path (here you can look your
libraries and import libraries)
Try do a clean and build
Check your JDK
If you have others eclipse installed on your computer look your file eclipse.ini and check than your JDK is correctly linked
I resolved this after coming across this bug report:
https://www.mail-archive.com/openjfx-dev#openjdk.java.net/msg22016.html
"As previously mentioned, the above exception is not thrown on machines where the Visual C++ 2019 redistributable is installed."
I downloaded the MS Visual C++ redistributable for 2015-2019 and installed it on two different computers with diff combinations of offAdoptJDK, jre_8u_202, and jre_8u_265, and this resolved my issue.
I downloaded the redistributable from the link below:
https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0
For Windows 10, I installed "x64: vc_redist.x64.exe" above and then my program ran successfully.
The problem
I've been trying to run a unit test on my own Mac. The test runs fine on Linux servers, but fails locally with the following trace:
java.lang.UnsatisfiedLinkError: no fedel_client in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1758)
at java.lang.Runtime.loadLibrary0(Runtime.java:823)
at java.lang.System.loadLibrary(System.java:1045)
....
What I've tried
Copy the .so file from the server
I've copied fedel_client.so from the server to /workspace/dapper/java/lib/native/macosx on my local machine, and added it to the java.library.path:
-Djava.library.path=/workspace/dapper/java/lib/native/macosx:...
Create a symlink
I've created a symlink from fedel_clinet to fedel_clinet.so, in case that Java is looking for the former (without the .so extension).
Add the .so directory to .bashrc
I've tried adding .so directory to PATH:
PATH=$PATH:/Users/adamatan/workspaces/trunk/dapper/java/lib/native/macosx
And to LD_LIBRARY_PATH:
export LD_LIBRARY_PATH="/Users/adamatan/workspaces/trunk/dapper/java/lib/native/macosx"
Print the java.library.path
I've printed java.library.path, to see if the changes in the Eclipse environment were propagated to the JVM:
System.out.println(System.getProperty("java.library.path"));
And got:
/workspace/dapper/java/lib/native/macosx:....
The exact values I placed in the Eclipse configuration.
Debugging ideas?
I got the exact same error with all the aforementioned solutions. Any idea how to debug this problem? Can I get a more verbose error message from Java? Is the file not found, or not loaded? If it isn't loaded, why is that?
I may be reading you wrong, but it sounds like you've copied the native library (libfedel_client.so) from the Linux server to your own Mac. If this is the case, this will certainly not work. You cannot use a Linux native library on your Mac, you will need to recompile it on the Mac to produce a libfedel_client.dylib.
Depending on the version of the Apple Java runtime you're using, you may need to use the .jnilib extension. Early runtimes used the .jnilib extension instead of .dylib, and both extensions are still supported (although .dylib is now the default.)
Can anyone please tell me why I get the following error when I try to run my Java programs? The programs get compiled successfully but are not able to be run. I have already set the path of Java.
C:\JavaServ>javac hello1.java
C:\JavaServ>java hello1
Error: could not open C:\Program Files\Java\jre6\lib\amd64\jvm.cfg
Don't think if this is a correct way...(perhaps proper installation of Java is a permanent solution)....but this is a trick..:)
Delete the “java.exe” file from “c:\windows” and “c:\windows\system32″. That should fix it.
In case you get here and scroll this far down, the newer Oracle versions of Java x86 and probably also x64 are horribly broken. You may find that after removing all versions of Java, and even manually deleting all the versions you find in c:/program files/ and c:/program files (x86)/ that you still can't properly run a fresh install of Java.
I'm here to tell you why, and how to fix it.
Go to C:\Program Files\Common Files\ and DELETE the Oracle directory. It has a version of Java underneath it inside a junction (symlink) that is sequestered away from all your other installs. Bastards.
Now, also go to System Properties -> Advanced -> Environment Variables and edit the PATH under System Variables. Find the place where the Oracle folder is referenced, and delete it. Close all your windows down, reboot to be extra sure if you want.
Install the JRE or JDK. Open a command prompt and type 'java' and if it comes up, you're golden. If not, go back to the PATH variable and add "C:\Program Files (x86)\Java\jdk1.8.0_221\bin" or whatever looks right for your machine.
I hate Oracle.
this should be an internal file of JRE and in general you shouldn't deal with it when you're running/compiling java.
Here you can find an explanation of what exactly this file is intended for.
Bottom line, your Java installation is somehow corrupted, so as a first resort to resolve this issue, I suggest you to re-install jre.
You should ensure that you're installing the right jre for your architecture.
Hope, this helps
You can not Uninstall/Reinstall JRE if you are having this error.
That's why because previous installation has copied 3 files namely Java.exe, Javaw.exe, javaws.exe in the c:/windows/system32 folder.
Simply go there and remove these files and download a fresh version of jre from oracle and install it. I will prefer JDK 1.6 update 45. Which is very stable.
update registry path to installation location
This happened for me when I moved out my default installation from an overcrowded primary partition to another location. Fir
Java mysteriously broke on my work PC after a security patch was pushed out to us, giving this error whenever you tried to run a Java program. Somehow the 'lib' subdirectory of the Java 7 install had vanished! It might have been related to having multiple Java versions installed simultaneously.
If you're getting this error there are basically two things that could be wrong:
1) Your Java installation is broken. If the file/directory it's complaining about doesn't exist, uninstall and reinstall the JRE and then it should be there. This fixed it for me.
2) If the files are there, your PATH is somehow incorrect or pointing at an old/broken Java install. In this case you either need to fix your PATH to point to the correct java.exe/javaw.exe, or use a fully qualified path. So instead of:
java <whatever>
Use
c:\<full path to correct JRE>\bin\java.exe <whatever>
3) If your PATH is correct and files are there and it's still failing, the path could be getting truncated because it is too long. see: Running Java gives "Error: could not open `C:\Program Files\Java\jre6\lib\amd64\jvm.cfg'" .
i also had the same issue due to one more instance of java,javaw and javaws in C:\Windows\System32 which was pointing to jre6 and my default location of jre was pointing to this(C:\Windows\System32) location. Even having jdk 1.8 as my JAVA_HOME location i were getting this problem.
so either remove or rename java,javaw and javaws it will work.
If you have installer deployed Java on Windows and decided to bring some order to your JDKs with folders moving...
All answers with java.exe in Windows\System32 are right but in more tough situation - there are no files, but error messages still happen, then remember about Windows Registry entries (look regedit.exe).
They store information about JRE folder in this registry key:
win32:
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment
win64:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment
The program can be compiled but while running it leads to such an error:
Could not open C:\Program Files\Java\jre6\lib\amd64\jvm.cfg
It indicates that the jvm.cfg file is missing in Program files. Reasons may be file corruption or file may be deleted. Install JRE again in "Program Files" folder.
Another case which happened with me is that I installed 32 bit jdk & jre in my 64 bit system in Program Files(x86) and my Program Files folder was empty. That was the reason for that error. So I installed 64 bit JRE in Program Files folder and it started to work. Note that it is not related to jdk version. Associated with only JRE problem.
I was getting the same error with my docear program on windows 7.
What I found is that I had two instances of java 1.6 installed on my computer. One instance has a jvm.cfg and the other does not.
Modifying my path to search the correct instance of java (in bold) first fixed the problem.
Here is my corrected path:
C:\Users\kranjit>path
PATH=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32
\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Enterprise Vault\EVClient\;C:\Program Files\Java\jre6\bin;C:\Program Files (x86)\Java\jre6\bin;
In our system, for "java(jre)" for runtime purpose is availed, So If you install any different version of java, propbably the version before the one which is already installed.
E.g.; my windows 8.1 I have runtime java version of 8, then when I install Ver7 it is bu default taking V8, yet I uninstall 8, In this kind of Scenarios, Removing java.exe from c:\windows\system32 makes my java runtime work
For anyone still having an issue I made mine work by doing this probably not the best fix but it worked for me..
I uninstalled all Java's that i current had installed, reinstalled the latest one and changed the install directory to C:/Windows/jre (Basically where it kept saying there was no config file)
If you have installed more than one jdk version , uninstall the others and keep only the one in use. this worked for me.
https://www.java.com/en/download/help/uninstall_java.xml
I want to add some pointers here.
Whenever you face the error saying Could not open jvm.cfg, it means that there was some mess happened with java installation path. Below approaches might help.
If java is added in environment path, then open command prompt and type where java. If you get list of directories where java path specified. Other than the directory where you need the java file, delete the java files in all other directories.
If you are reading 2nd pointer, then 1st pointer might have not helped. Type regedit in run dialog and under HKEY_LOCAL_MACHINE, go to softwares/javasoft and rename the paths of the java installed directory.
Let me know if above approaches solve the problem.
The simple Solution is just uninstall the javaSE and reinstall it to the default location.
Then copy the installed location probably like C:\Program Files\Java\jdk1.8.0_131\bin.
After then go to desktop then while selecting right click on My Pc or This pc shortcut the under that select properties >> Advanced system settings >> under Advance tab >> last option Environment Variables..>>path >> edit >> past >> ;(not required if win10)/(required if windows 7)
I had this issue when installing 201, somehow it didn't uninstall my 191 properly. I had to go to the Program Files/Java folder, rename the old 201 directory, then install a fresh copy of 201. When doing so, it prompted me to uninstall 191, which I did. Now it's working fine.
I was facing the same issue after upgrading my java version.I had more than one jdk installation. I have manually uninstalled the old jdk version . Then it worked for me.
Resolved
I had similar issue, I tried different things but nothing worked. Then when I checked the installed programs. I could see two versions of java installed.
What I did is, just uninstall all java versions and freshly installed the required version. But this didn't seem to work when I checked in terminal. Then I had to reopen the terminal and run the command, then only it worked.
Note : Dont forget to reopen the terminal if you are testing via terminal.
I had an identical error trying to start IntellJ with a custom JBR.
C:\Users\user>"C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2021.3.3\bin\idea.bat"
Error: could not open `C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2021.3.3\jbr-arm64\lib\jvm.cfg'
This issue may occur if there were problems extracting Java or OpenJDK from a zip or tarball (e.g. a slow extraction was terminated prematurely) or if the zip or tarball was corrupted or incomplete.
If caused by a corrupted zip or tarball, try redownloading the archive.
If caused by a bad extraction, repeating the extraction will fix this.
Copying and pasting i386\jvm.cfg from a different PC will resolve the issue.
I had the same issue.I just uninstalled Java and reinstalled again it worked fine after that . The problem is related to JRE so you can just reinstall JRE.
I had same problem - when I tried to run a Java program from command line the error message appeared: "Error: could not open jvm.cfg".
My Path environment variable included following path:
C:\ProgramData\Oracle\Java\javapath
In the folder there were 3 exe files:
java.exe
javaw.exe
javaws.exe
When I removed the the entry
C:\ProgramData\Oracle\Java\javapath
from the Path environment variable and restarted cmd, I could run the program as usual (java MyProg).
Obviously I have corrupted the path pointing to correct java jre installation
C:\Program Files\Java\jre1.8.0_151
somehow previously when I played with my settings.
It means that this jvm.cfg file is not found. Maybe it was deleted. Reinstall the program. If you have this problem with a game for example, reinstall Java in the games folder, or copy Java files .de c:/Program Files/JAVA and paste to the JAVA folder in the game folder
I'm running a Java application on a Linux server that uses Tibco RV and I get the following error:
TibrvException[error=901,message=Library not found: tibrvj]
What is causing this problem?
I have already added lib path containing *.so into LD_LIBRARY_PATH but still the same result.
UPDATE:
Currently, I have <MyApp>/libs/tibrvj.jar added into classpath. The tibrvj.jar was copied from Windows environment to the Linux box where I'm running my application. I removed this from the classpath and added another reference <TibcoDirectory>/libs/tibrvj.jar and it FIXED the problem. They have different sizes with the previous file and there's probably a difference between the one copied from Windows and the one currently in the Linux box. Can someone explain why is this so?
I had the same problem, and I fixed it doing the following:
File tibrvj.jar is present in the classpath of my application
File tibrvj.dll is present via java library path. This file is usually located at bin directory in Tibco Rendezvous home directory (e.g. C:/tibco/tibrv/8.2/bin)
The installed java version is compatible with the installed tibco version.
My environment is:
Windows 7, 64bits
Tibco Rendezvous 8.2, 64bits
JDK 1.6u29, 64bits
Before, I had installed a JDK 1.6u17, for a i586 processor and when I tried to load the library using:
System.loadLibrary("tibrvj");
I got this error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\TIBCO\tibrv\8.2\bin\tibrvj.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform
It gave me the clue to instal the correct java version.
Have you loaded the library using System.loadLibrary("tibrvj")? Have you added it to java.library.path?
Use :
java -Djava.library.path=/opt/tibco/tibrv/lib -cp {}.jar
LD_LIBRARY_PATH=/opt/tibco/tibrv/lib export LD_LIBRARY_PATH
Then **System.loadLibrary("tibrvj");**
The answers by rchavarria and DaveHowes helped, but for me the problem was that my IDE was overriding the PATH variable (and hence java.library.path) when running my project.
Removing this override made it work, as outside the IDE tibrv was already on the PATH.
Are you using Wrappers?
Do you have java.library.path set in your wrapper.conf?
I had java.library.path set in wrapper.conf, correct this value fixed the issue for me.
Eclipse is unable to open, have used eclipse before and has open before without a problem. Now I keep getting the following error message:
A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations:
Have gotten eclipse to open and work on projects before and won't open.
Here is a screen shot of what I keep getting:
You can explicitly tell Eclipse where to find it. Open eclipse.ini and add the following lines to the top of the file:
-vm
/absolute/path/to/jre6/bin
Update: I just nailed down the root cause on my own Windows machine. The GlassFish installer complained with exactly the same error message and after digging in GlassFish forums, the cause was clear: a corrupt JRE install on a Windows machine. My JRE came along with the JDK and the Java 6 JDK installer didn't install the JRE properly somehow. A DLL file was missing in JDK's JRE installation. After I reinstalled the standalone JRE from http://java.com, overwriting the old one, the GlassFish installer continued and also Eclipse was able to start flawlessly without those two lines in eclipse.ini.
I got this problem because i uninstalled the jdk version 13 and reinstall the jdk version 8
Even though i have updated the path variables eclipse still pick the old configuration.
You need to edit the eclipse.ini file which is in your folder where eclipse.exe is placed.
Just update this file with the latest path so eclipse can pick it up
It usually is because:
you indicated the wrong jvm path in your -vm argument: see this SO question for an concrete example.
the eclipse.ini got corrupted somehow (if it hasn't been modified, this isn't it, but if setting a jvm path doesn't work, ... I would replace the eclipse.ini by one coming from a fresh installation just to be sure)
the java which eclipse search by default is no longer accessible (because the $PATH is no longer up-to-date)
More details on the wiki page "Finding a VM, Using JNI Invocation or Executing Java"
No -vm specified
When no -vm is specified, the launcher looks for a virtual machine first in a jre directory in the root of eclipse and then on the search path.
If java is found in either location, then we look for a jvm shared library (jvm.dll on window, libjvm.so on *nix platforms) relative to that java executable.
If a jvm shared library is found we load it and use the JNI invocation api to start the vm.
If no jvm shared library is found, we exec the java launcher to start the vm in a new process.
As mentioned in "FAQ How do I run Eclipse?":
Eclipse DOES NOT consult the JAVA_HOME environment variable.
So I would check your $PATH, starting by n new shell sesion (whatever your OS is), typing 'java -version' to see if it still returns anything.
Copy javaw.exe from C:\Program Files\Java\jre1.8(or)1.6(or)1.7\bin
and paste it inside Eclipse folder
where eclipse.exe is there. That's all.
Here is how I fixed mine:
find the location where your jre is installed. in my case, it was located at C:\Program Files\Java\jdk1.7.0_10
copy the jre folder and paste it where your eclipse files are located (where eclipse.exe is located).
when you download eclipse, you get a .zip package containing eclipse.exe and all the other files needed to run eclipse but it is missing the jre files. so all you need to do is to find where jre folder is located on your hard drive and add it to the rest of the eclipse package.
I had the same problem and the issue was that I had a 32 bit version of Eclipse running on my 64 bit machine and it wanted the 32 bit version of JRE.
I changed Program Files to Program Files (x86) in the eclipse.ini file like so:
-VM
C:Program Files (x86)\Java\jre6\bin
and that solved the problem.
You may want to just install the 64 bit Eclipse, but this will take care of the error.
Did you install Java via the java.com web browser auto install? If so, then that's your problem! You need to to the "manual" install: http://www.java.com/en/download/manual.jsp
It's just a matter of having the correct match of 32-bit Eclipse/32-bit Java or 64-bit Eclipse/64-bit Java. Many 64-bit Windows have 32-bit browsers and the latter is the version of Java that the auto-installer will provide - not what the 64-bit Eclipse wants.
Make sure the install path of JDK is in your Path variable in Windows.
adding -vm C:/Program Files/Java/jdk1.6.0_29/bin/javaw.exe to the .ini file helped me.
Is so simple,only add your java path for example:
C:\Program Files\Java\jdk1.8.0_121\bin
in PATH system variable
I have faced the similar issue earlier with Eclipse and STS IDE'S
Please check weather JDK/JRE is available or not in your machine. If not please install JDK and setup the environment variables.
Even after step 1, if you are still facing the issue then it's time to set the vm argument in eclipse.ini or sts.ini in the following way.
-vm
C:Program Files (x86)\Java\jre8\bin
I also had same problem when developing android applications using eclipse IDE.
I solved it by removing all the java installations (I had java 6 and 7 both) and re-install only jdk 7.
I got this fixed by doing the below steps,
1)
The eclipse finds the JAVA executables from 'C:\ProgramData\Oracle\Java\javapath'
The folder structure will contain shortcuts to the below executables,
i. java.exe
ii. javaw.exe
iii. javaws.exe
For me the executable paths were pointing to my (ProgramFiles(x84)) folder location
I corrected it to Program Files path(64 bit) and the issue got resolved
Please find the screenshot for the same.
Just to add on top of other answers:
Windows Users: You can give the PATH to JRE in eclipse.ini separated by '/' or '\'. It doesn't matter. Eclipse will pick it anyway. For example, in my windows system, either of the paths is fine (after -vm of course):
C:/Program Files/Java/jre1.8.0_181/bin
or C:\Program Files\Java\jre1.8.0_181\bin
Change the vm value in eclipse.ini file with the correct path to your JDK something like this,
-vm /Library/Java/JavaVirtualMachines/jdk-11.0.5.jdk/Contents/Home/bin
Path to eclipse.ini looks to me something like this,
/Users/tomcat/eclipse/jee-2018-09/Eclipse.app/Contents/Eclipse
This sometimes happen if you remove Java from your path variables.
To set the PATH variable again, add the full path of the jdk\bin directory to the PATH variable. Typically, the full path is:
C:\Program Files\Java\jdk-11\bin
To set the PATH variable on Microsoft Windows:
Select Control Panel and then System.
Click Advanced and then Environment Variables.
Add the location of the bin folder of the JDK installation to the
PATH variable in system variables.
I had this problem too on a win7 machine.
I wanted to update the jre with a jdk. So i deleted the jre folder and downloaded and unzipped the new jdk.
The issue was i manually deleted the jre folder, when instead i should've uninstalled it. This leaves a bunch of registry entries that still point to the old jre. Somehow eclipse still wants to use the old jre.
I couldn't uninstall the old java vm, i kept getting this error:
Error 1723. There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor
So i had to use this MS utility to fix the uninstall:
http://support.microsoft.com/kb/2438651/
Then i had to install again the vm. I installed to the same location the original one was at, to avoid losing another hour! After that eclipse started correctly.

I just had this problem and fixed it this way. I noticed the error message has jre in it not jre6 or jre7, so i copied jre6 from program files to eclipse folder then renamed it from jre6 to jre, then it worked :p
Newb move on my part, but I had installed just the JRE instead of JDK. Installed JDK and my problem went immediately away.
I had this problem and it was due to my windows machine playing up. I went into control panel -> system -> advanced - environment variables.
I edited the PATH variable (which was already correctly set up), changed NOTHING, clicked OK to come back out of the screens.
Then eclipse worked. No idea why, except because windows. Hopefully this may help someone.
I had this issue; I fixed it by going to
Computer-->Properties-->Advanced Settings-->Environmental Variables
In the System Variables find the variable named PATH.
-->Select Edit
-->At the very end of the Path Variable, put a ";" then add your path of your JDK and put \bin\ at the end
Should be fixed.
Example:
System Variable-
C:\Program Files (x86)\Common Files.......HP\LeanFT\bin
JDK path-
C:\Programs Files\Java\jre1.8.0_121
Final Path -
C:\Program Files (x86)\Common Files.......HP\LeanFT\bin;C:\Programs Files\Java\jre1.8.0_121\bin\
Sources:
https://www.java.com/en/download/help/path.xml
Its simple.
JDK bin directory or JRE bin directory should be in path variable
Example :
Java Installed directory:
Assume your java installed in 'C:\Program Files\java\Jdk1.8.0_144' directory
Now you can find bin directory in 'C:\Program Files\java\Jdk1.8.0_144\bin'
Navigate to user's environment variable
Control Panel --> User Accounts --> User Accounts --> Change my environment variables
In popup click Path under User variables for section
Click Edit... button and another popup will appear
Click New button and enter C:\Program Files\java\Jdk1.8.0_144\bin
Click OK button and again OK button in Environment variables popup.
Now you can open your eclipse without error
I found a solution wherein the Eclipse.ini the location was the old version of Java, and after updating the new version of java the location of
-vm
C:\Program Files\Java\jre1.8.0_201\bin
was same so I had to change the directory to my new version of Java.
So solution is to just open the most updated Java version and copying its directory path and replacing it in the Eclipse.ini file.
Moderately future proof example for Linux-like systems. Assuming javac installed and on your path.
./eclipse -vm dirname $(readlink -f $(which javac))
This will find the directory where javac is installed, and pass as vm argument to eclipse.
If on Linux (ex: Ubuntu 18), try installing (or reinstalling in your case?) default-jre, as follows:
sudo apt update
sudo apt install default-jre
I had the same error when just trying to run the Eclipse installer (./eclipse-inst) on a fresh Eclipse download just now, and the installer wouldn't even run! Installing default-jre solved it!

In my case I had edited the eclipse.ini for a different purpose to include -vm parameter. That was causing the failure. I removed the -vm and following line where I had included \bin and that fixed the problem.
I got ERROR:
RESOLUTION :
in file eclipse.ini at below location :
make change as :
-vm
C:/Program Files/Java/jdk1.8.0_251/jre/bin/server/jvm.dll
Restart eclipse and error will be resolved
C:\Program Files\Java\jre1.8.0_221\bin
worked for me
