I am using Netbeans 6.7. I had first installed Java 1.5 before installing Netbeans. When i installed Netbeans it took Java 1.5 as the default version. Then i installed Java 1.6 on my machine. I need to change the default JDK of my netbeans to 1.6 not only to a specific project but to the whole Netbeans application.
You can change the JDK for Netbeans by modifying the config file:
Open netbeans.conf file available under etc folder inside the NetBeans installation.
Modify the netbeans_jdkhome variable to point to new JDK path, and then
Restart your Netbeans.
In my Windows 7 box I found netbeans.conf in <Drive>:\<Program Files folder>\<NetBeans installation folder>\etc . Thanks all.
For anyone on Mac OS X, you can find netbeans.conf here:
/Applications/NetBeans/NetBeans <version>.app/Contents/Resources/NetBeans/etc/netbeans.conf
In case anyone needs to know :)
open etc folder in netbeans folder then edit the netbeans.conf with notepad and you will find a line like this :
Default location of JDK, can be
overridden by using --jdkhome
:
netbeans_jdkhome="G:\Program
Files\Java\jdk1.6.0_13"
here you can set your jdk version.
on Fedora it is currently impossible to set a new jdk-HOME to some sdk. They designed it such that it will always break. Try --jdkhome [whatever] but in all likelihood it will break and show some cryptic nonsensical error message as usual.
Fix this by moving my jdk folder to other disk
Either change the jdk home in the application preferences or look for the application's config files.
On Mac OS X, its in a netbeans.conf file, and look for the jdk home value.

Netbeans would not find compatible jdk while installation while JDKs are located at C:Java and the files are:
jdk-8u73-windows-i586
jdk-8u73-windows-x64
jdk-8u141-windows-i586
From NetBeans Installation Instructions
The default location in Windows is C:\Program Files\Java\jdk1.7.0_10 or similar.
If your JDK is at C:\Java you just have to:
re-install the JDK under the default Netbeans location, or
specify your custom location during the installation wizard
Since I've run into this problem and this Q/A came up in my search, here is the solution that I found worked for me on the Windows platform.
I had to set up an system environmental variable named JAVA_HOME that pointed to the JDK directory.
JAVA_HOME=D:\Program Files\Java\jdk1.8.0_144
Even after this change, I still ran into the "An unknown error occured while validating path."
Right-click on the NetBeans install software and select "Run as Administrator...". It looks like running the installer under your normal account, even though it may have admin rights, is not enough to scan the "\Program Files" folder and find the JDK.
*Delete your old java files.
*Download jdk file from.
https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
*install new jdk version.
*Then install NetBeans //Now it will automatically identify your jdk and no need for manual selection...
I am trying to use Eclipse on a friends computer but we keep getting this when we run Eclipse
We have the environmental variable set as well.
Edit
it was working before he installed the black berry plug in.
The variable JAVA_HOME is not required by Eclipse. If your Java installation does not put the Java executables in the PATH, you should add those manually.
A faster way to have your Eclipse up and running consists in modifying the eclipse.ini and using the -vm option.
http://wiki.eclipse.org/Eclipse.ini#-vm_value:_Windows_Example
I had the same problem. For me, I needed the JDK. So I had to install the JDK. It should match the build platform that is, 64bit vs. 32bit windows. After that, I removed, the -vm line from the eclipse.ini file (the suggested fix). It was giving me the "Can't create virtual machine" error. The current release of JDK is version, 7 whereas the Android Developers Toolkit version of eclipse is currently based on JDK 6. But it seems to work. Eclipse came up and is functional. Haven't actually written a program yet.
Go to eclipse folder (where eclipse is installed) and open eclipse.ini file in your editor and add the following code after openFile tag.
-vm C:\Program Files\JDK6\bin\javaw.exe
That's all.
I had a similar problem, since our Java and JDK is consistently updated by our service desk, including uninstalling old JDKs. They take care of the PATH for us, but then the JRE that Eclipse was used to "seeing" was gone. So, the thing that has worked best for me is to modify the shortcut's "target" from:
"C:\Program Files\Eclipse\Eclipse IDE for Java EE Developers\eclipse.exe"
to
"C:\Program Files\Eclipse\Eclipse IDE for Java EE Developers\eclipse.exe" -vm "C:\Program Files\Java\<jdkver>\jre\bin\javaw.exe"
That will point Eclipse toward to the JRE in the JDK you want it to use, and then you can update that shortcut when your JDK updates.
This is on Windows 64bit, obviously.
It can also happen on mismatch of JAVA and Eclipse bit version.
for eg:
If in your System java is 32 bit and you are trying to install Eclipse of 64 bit then the same situation might occur.
Because Eclipse will look Java in Program Files while at the same time Java may be present in Program Files (x86).
So in this case eclipse will not get java and throw the same error.
While installing eclipse, Jre missing :
I solved my error as follows:-
This error may comes if you have 2 program files folder in your system.
"Program files" &
"Program files x86".
Please install JDK&JRE in the "Program files" folder.
Hope your jre missing error get solved.
this works for me:
open eclipse.ini file in your editor and add the line: -vm C:\Program Files\JDK11\bin\javaw.exe
update system PATH with correct JDK path.
I recently decided to start trying Android app development, so I downloaded the Java SE Development Kit 8 (x86) for Windows (I got Windows 8 64bit, but my guide recommends getting the 32bit one), the Android SDK, and the Eclipse IDE for Java Developers (x86).
However, my Eclipse won't launch when I double click eclipse.exe! Instead, I get the following error message:
I tried adding Java to my Path variable in my Environment variables as suggested in some of the solutions I looked up, but it still doesn't launch properly.
Anyone know what else I can try? Also, if possible, please do not use super-technical vocabulary as I'm new to these kinds of stuff and will not understand you...thank you haha :D
I had the same issue and was trying to install different versions of JDK: 1.6, 1.7, 1.8.
It didn't help much.
The problem was resolved when I changed PATH variable by removing
C:\ProgramData\Oracle\Java\javapath;
In command prompt I also ran following commands:
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25
set PATH=C:\Program Files\Java\jdk1.8.0_25\bin;%PATH%
But I think the most important was to remove C:\ProgramData\Oracle\Java\javapath; from the PATH.
I know exactly how to solve your problem. Go to search and put in environment, a prompt will come up and ask you to "Edit environmental variables for your account" click that and a window will pop up. There will be the current paths which are running on the top (you should have your JDK version running, mine is 1.8) and on the bottom part there will be paths to choose from. Select (on the bottom part) the java path and delete it, then click okay. This should work.
If it didn't work, You may also add a new path to the java bin folder which worked for me.
Here is an alternative:
As described here, make sure that you have the -vm option set in your eclipse.ini file.
It must be an absolute path and on 2 separate lines:
-vm
<Absolute Path>\javaw.exe
Save your .ini and relaunch Eclipse
One line answer, remove 'C:\ProgramData\Oracle\Java\javapath;' from your path variable. It will start to work.
Most errors with starting eclipse happen due to multiple JRE or JDK version which makes the installer go nuts.
Solution: Go to Control Panel -> Uninstall Programs
If you're running 64-bit java, then uninstall all Java without the 64bit indicator. If 32-bit, then uninstall all that have 64-bit
It works like magic!
What worked for me was having installed adoptopenjdk11 using Chocolatey package manager:
choco install adoptopenjdk11
I'm trying to install eclipse on maverick. I've installed Oracle java 1.7 and can launch eclipse using the link I found in the untared eclipse directory. However, when I pin the icon to the mac dock, trying to open eclipse using that icon results in 'Software Update' telling me 'To open "Eclipse," you need a java SE 6 runtime. Would you like to install one now?'
I guess that this method of launching is somehow not using the eclipse.ini file in which I have used the -vm option to specify that eclipse be launched using the oracle 1.7 version of java on my system.
Anyone know how I can fix this? I wondered if I can edit a config file for the doc entry similar to the way I can add items to ubuntu's launcher perhaps?
I was able to fix this by running Apple's Mavericks Java fix. Even though the fix claims to install Java 6 it ended up just reconfiguring my already installed Java 7 and Eclipse is now able to run normally from the dock and command line. My default JVM is still java 7.
http://support.apple.com/kb/DL1572?viewlocale=en_US
Do you have the latest version of 1.7?
Oracle's Java version 7u25 and below have been disabled by Apple on OS X.
https://www.java.com/en/download/faq/java_mac.xml
Ah,your question solves me . After I update my MAC OS X to mavericks,I can not open my eclipse .I use "open Eclipse.app" or click eclipse on dock .It doesn't work .says"your need java se 6 runtime"
Then I follow your advice ,run "Eclipse.app/Contents/MacOS/eclipse",greet! I open it.
It seems this is the only way to run eclipse on mavericks~
I have a sneaky suspicion that I have a fix for this, but as my system has 1.6 in already I can't test it at the moment.
In the eclipse.ini file you will find the following vm arg; -Dosgi.requiredJavaVersion=1.6 I have a suspicion that if you changed this line to
-Dosgi.requiredJavaVersion=1.7
you might find that you could launch eclipse without the need for java 6. OSGi is the technology that Eclipse uses to manage and run its plugins.
The location of eclipse.ini is dependent on the system but on a Mac you can find it in /Eclipse.app/Contents/MacOS/eclipse.in.
I am trying to work with Eclipse Helios on my x64 machine (Im pretty sure now that this problem could occur with any eclipse) but it just doesn't cooperate.
When I try to run eclipse I get the following:
I have installed
Helios EE x64 (latest version)
JDK 1.6.025 (x64)
I have linked my Environment Variables up correctly and tried to compile a Java file through cmd and have succeeded.
Whenever I tried running eclipse i get exit code=13 (required java version=1.5)
I tried running the following in cmd:
-vm "mypath\jdk1.6.025\jre\bin"
command as forums suggested
as well as other paths
-vm "mypath\jdk1.6.025\bin"
-vm "mypath\jdk1.6.025\jre\bin\javaw.exe"
even
-vm "mypath\jre6\bin" out of desperation
to no avail.
I am all out of ideas and I wonder if anybody had this problem. I even downloaded the helios x86 version and x86 JDK version yet it did not fix the problem. (I changed the environment variables)
I changed everything back but I'm stuck...
Related Question: Cannot Run Eclipse
It turns out that a directory had an ! in its name and eclipse had a problem with that.
Once I switched the directory (from Desktop which is located in the user directory which had ! in it to C:/ ) everything worked fine. (look at the Djava.class.path in the image located in my the question above for the whole path - it should make it clear what the problem was)
Vista allows you to create a username that contains ! character and then a lot of programs have issues with it
Update
If somebody is still getting this problem even though their path is ok I suggest
trying to look at the Environment Variables
then try uninstalling the Helios EE ( or any other version of ee you are running ) and JDK and then reinstalling the 86x versions of both (they should still work on the 64x platform).
for further explanation look here
Thank you everybody that tried to help
Please, check that your have downloaded the x64 version. ;)
And your installed Java, is x86. Use Eclipse x86 if you use Java x86.
Because your eclipse's env-arch was not matched with java-arch, for instance: eclipse-64bit run in java-32bit or vice versa.
In Windows: Set correct env path to the specific 32 or 64bit java acording to eclipse.
In Linux:
Try run: [path-to-eclipse]/eclipse -vm [jdk-path]/bin
What version of java is on your path when you start eclipse? Try entering java -version on a command prompt. You will want Sun java 1.5 or higher. See http://www.ehow.com/how_4784069_terminated-exit-code-error-eclipse.html
This turned out to be a permissions error for me. I change the kepler folder, eclipse root directory to have permissions set to everyone all. This is going to be a security risk so I will need to set the permissions to be program specific. using procmon.exe I found that javaw.exe was getting write permissions denied. The programmers of eclipse and javaw.exe did not give those programs elevated permissions to run as trustedinstaller.
I faced the same problem
Turned out my Java version in the PATH had been updated to 1.8
Once I changed this back to 1.7, my Eclipse started without issues
