Trouble with Eclipse - java

I have downloaded eclipse for J2EE developement
what seems to be my problem?
the files at the address (C:\Program Files (x86)\Java) are:
jdk1.6.0_02,
jre1.6.0,
jre1.6.0_02,
jre7

It is possible if the eclipse is 64 bit and the JDK or JRE is 32 bit. Check this.
C:\Program Files (x86)\Java
tells that you are using 32 bit JRE and JDK, but the JUNO that you have is of 64 bit. So use 64 bit JRE/JDK and the problem would be solved.

I'm not joking about this: a friend of mine had this issue loading Netbeans 7, and we couldn't figure it out. Eventually for some reason he closed his desktop clock gadget (the one that comes with Windows 7) and suddenly it started working again. I can't explain how or why it worked, but don't rule it out (unless of course you aren't using gadgets).

Eclipse doesn't start in windows 10

Eclipse doesn't start in windows 10. When I click on Eclipse, it just appears for a second and closes quickly. But previously I worked properly.
just reinstalling JRE ,I have solve it
If your Eclipse is 64 bit then make sure you have JRE 64 bit installed and it is latest one and if your Eclipse is 32 bit then you need latest 32bit JRE to work
Uninstall eclipse than check you's system configuration than install 32 bit or 64 bit according to your system compatible. Make sure eclipses and JDK both shared same bits.

Can somebody help me resolve some frustrating conflicts with Java, Ant, and Eclipse on a 64 bit Windows 8.1 system?

Background: I’m setting up an automated build system, with Selenium (Java), Ant, Eclipse and Jenkins on a virtual machine running a 64 bit version of Windows 8.1.
Problem #1-
The latest version of the 64 bit JDK (1.8.0.72) doesn’t seem to include tools.jar, which ant (version 1.9.6) seems to depend on.
My solution has been to download the 32 bit version of the JDK and set all environmental variables accordingly.
Which leads to Problem #2-
Now that I have reset my environment to point to the 32 bit JDK, I can no longer start Eclipse without an error message “Failed to load the JNI shared library.” I have tried to resolve this error by adding a line to my eclipse config file to point to the correct JVM (jvm.dll), but that isn’t working.
Thanks for the quick suggestions. I have come up with a solution (or at least a decent workaround).
Download 32 bit and the 64 bit version of the JDK. Set my JAVA_HOME var to point to the 64 bit JDK, which satisfies Eclipse, and then copy the tools.jar file included with the 32 bit JDK to the 64 bit JDK. Not very elegant, but for now it seems to be working. Ant and Eclipse are both happy.
It is strange that downloading the 64 bit version of the JDK doesn't include tools.jar. I tried 8u71 and 8u72 for windows 64 bit without any luck.

Unable to install Java on Windows 10 (1603 Error)

I tried to download Java on my laptop (which has windows 10) but i keep getting a 1603 error. My computer used to have windows 8.1 and it did not work back then either
I appreciate any advice to solve or work around this problem
I have had this problem. I was able to fix it thanks to a co-worker. The problem started happening after I installed HP Unified Functional Testing (UFT, aka QTP). Installing this product changes the Windows environment variables used by Java. He told me the following: "So change the names of JAVA_OPTIONS, IBM_JAVA_OPTIONS, JAVA_TOOL_OPTIONS to something else (both in system and user variables) and delete any Java folder(in Program Files (x86) or Program Files) which gets installed despite the error. Restart the system and then try installing Java."
Actually, all I did was rename the environment variables and run the installer. This worked.
My answer is not related to win 10, but might help someone who is having similar problem in windows 7 machine and not able to install jre 32 bit version.
the work around to this is once you downloaded the jre, copy the path "C:\Program Files (x86)\Java\jre1.8.0_121\bin\javaw.exe" and paste it under java runtime environment settings which is found -Java Control panel>java>view
I think you downloaded the wrong version. If your laptop support x64 bit software you should download Java 1.8 x64 version.
Here is the link.

I had this problem for a month now. I tried everything on my windows 8, but I couldn't get the latest java on it. When I tried to install java on an empty computer, the 64 bit version did not go through (error 1603) and I realized the problem didn't come from an old java install and I install 32 bit. it worked on the new computer with windows 7 and on my computer running 8.1.
note: I had deleted all the java versions before going through with it.
To fix java 1603 error you have to follow few simple steps.
First of all remove all old java version.
Then remove some windows update file which might be reason of this
error. Like KB2918614 update.
After that download and Install latest version of java and activate
java in browser. Now everything will be fine you can test the java
version on java website...

I encountered this error on Windows 8.1 and when I checked with Oracle web site, they said that is is not yet resolved, and under investigation. They also showed a link for off-line installation as an alternative arrangement. However, upon investigation of my system, i found out that the available space in C drive was only about 20 MB or so. I cleared my system and provided enough space. When I tried with the extra space, I didn't encounter any error. May be, you could try with a better free space...
First you should close the browser because if any webpage will use Java, it will cause conflict. Then do custom installation, i.e. install in some other folder other than default folder and point environment variable to newly installed Java location. It will resolve your issue.

Eclipse jvm.dll error when loading

Trying to open Eclipse after a couple of months and get this error:
So I checked that folder to see if it existed, and it did:
I checked my PATH Was correct and it was also correct:
When this error first occurred I had 3 Java installations. JRE 7 Update 10, JDK 7 Update 7 32bit and 64 bit.
I uninstall ALL and restarted my machine. Eclipse then stated, as expected that I needed a JRE or a JDK. So I downloaded and installed the latest JDK and now I get this error, despite everything appearing to be correct.
Any ideas?
As requested in the comments.
Your eclipse version is searching for the x86 version of the jdk (You probably set this value when eclipse started). You should check if your eclipse is a 64 bit version if not, switch to a 64bits jvm.
the problem lies with compatibility issue of jdd 6 with eclipse.I tried jdk 7 and it worked perfectly.Here is a link for jdk 7 downloading

The problem is with the Eclipse version. I faced the exact same problem, I was using Eclipse helios. I switched to Eclipse Kepler 64 bit and it is now working perfectly on my system. Even if the eclipse is 64 bit, some versions may not be compatible with other softwares using the same Java path (Eg: Oracle BI Publisher). Make sure to use the version compatible with others.
FIX for :: jvm.dll file missing issue while you open eclipse
This issue appears because of (64 or 32 bit) version conflict/mismatch happens between
installed OS,
Java(JDK)version and
eclipse version.
I got this issue and fixed it in this way.by adding the below argument (64 bit Java(JDK) path) in eclipse.ini.
-vm
C:\Program Files\Java\jdk1.8.0_144\bin
My environment,details below
Mine is windows-7 64bit OS,
Java(JDK) 64 bit (so path specified in eclipse.ini)
Eclipse 64 bit(never confuse the eclipse version as 32 bit by seeing the win32.x86, see the later _64) i.e I use eclipse version below.
org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.500.v20170511-1520
You can see your eclipse version in eclipse.ini file.
Note:
I have another Eclipse (plugin tool) installed in my machine, which had the same issue, was expecting 32 bit Java(JDK), After I fixed the issue by setting the path for 32bit Java1.8 in environment variables, the primary eclipse stopped working.
So I set 64bit Java1.8 path in eclipse.ini.
Now both eclipse.exe and my plugintool eclipse working fine.
Thanks,
Murali
Here we fristly check the ur path. when ur path is correctly. Then after u will move the given location (their checking jvm.dll file will be presented or not).
that type problem came max to max 64-bit systems.
Here main focus on path. when u set path then after retsart the system.
This happend to me yesterday and fortunately I found this post.
I was working on eclipse and tried to compile a class using the command line in paralell. I noticed that the javac command wasn't on the Path environment variable so I added.
Afterwards, I closed Eclipse and when I tried restarting the IDE I found the "Failed to load JNI shared Library" error.
I opened back the environment variable dialog box and pointed the java bin path to a compatible version of java (Same bit version on both, eclipse and jdk).
Finally I was able to start eclipse again.

Problems Installing Android SDK

I have had to install Java and Android on my new machine. I've downloaded jdk1.6.0_27. It's installed in C:\Program Files\Java\jdk1.6.0_27.
I've set the classpath env var to C:\Program Files\Java\jdk1.6.0_27\lib and the path var to C:\Program Files\Java\jdk1.6.0_27\bin. in cmd java - version works fine.
When i try to download Android, it checks to see if java is installed first. It's stating java not installed on my machine. I can't proceed with the Android download. Is there a reason for this?
Thanks,
Matt
This sounds crazy, but it works.
When that happens: press back, then next. I'm dead serious. It will detect java the second time around. I have no idea why.
As verified here:
Android SDK installation doesn't find JDK
I had the same problem, tried all the solutions but nothing worked. The problem is with Windows 7 installed is 64 bit and all the software that you are installing should be 32 bit. Android SDK itself is 32 bit and it identifies only 32 bit JDK. So install following software.
JDK (32 bit)
Android SDK (while installing SDK, make sure install it in directory other than "C:\Program Files (x86)", more probably in other drive or in the directory where Eclipse is extracted)
Eclipse (32 bit) and finally ADT.
I tried it and all works fine.
Do you have a JAVA_HOME variable defined? That might help. On my system I have JAVA_HOME set to
C:\PROGRA~2\Java\jdk1.6.0_24
A little odd perhaps (using the "~" dir instead of the "Program Files" dir, but seems to help with some older scripts that don't expect to see spaces in the path name.
