I have Windows 7 64 bit OS, I was just using Eclipse Helios, before I restart my pc, after the restart I am not able to use eclipse anymore. when I click on the eclipse icon, it opens but while loading it just stuck there, and when I click on it, I get the following message: JAVA (TM) Platform SE is not responding.

So, does anyone know what should I do?

  • you need to install a proper version of JAVA SDK check out eclipse compatiblity with x64bit . I think there is no eclipse x64 , so you need to install only JAVA SDK x86 and remove the x64 version

  • Did you apply any changes to the OS, e.g. Java Upgrade?

  • A lot could be said about operating systems on which you can install Java without needing to have the admin password and which won't pollute other user accounts. I did manage to get similar issues on Linux and after getting stuck for a bit too long I did: a) save all my files (they're saved regularly anyway) and then b) delete all trace of the user account and c) re-create the user account and re-install Java + my IDE + all the rest. Pretty extreme, but on a system where you decide who's the boss, it's pretty failsafe. It's the b) part which is problematic with Windows.

Nima, Are you on a 64 bit version of the JDK and 64 bit version of Helios? . If not try having both on 64 bit, so that you can leverage your OS. Also, edit your eclipse.ini file to launch it pointing to a specific vm. eg :

-vm
myjdk/1.6.0_22/bin/javaw.exe

[SOLVED] Issue resolved with deleting the .snap file from yourworkspace\.metadata\.plugins\org.eclipse.core.resources

Explanation for the snap file : While Eclipse is running, information about what has changed in the workspace is incrementally logged into various "snapshot" files (including .snap). On normal Eclipse shutdown, the complete workspace state is saved and the .snap files are deleted. When Eclipse crashes, the snapshot files are used during the next startup to recover from the crash.

So, it appears that some error is occuring that is causing Eclipse to crash. Then, there is an error recovering from the crash on the next startup. These are quite possibly unrelated problems, but by manually deleting the snapshot file you are tricking Eclipse into thinking that a crash did not occur, so the crash recovering routines do not run.

  • You can try using eclipse -clean to try launching up again. Also try deleting the .snap file in yourworkspace\.metadata\.plugins\org.eclipse.core.resources

Reinstall eclipse and/or Java Runtime Environment. You can install either 32/64 bit version, but if you run eclipse 32 bit you need 32 bit JRE, with eclipse 64 bit, 64 bit JRE is required.
