if the latest JDK is JDK6u20 then upgrade since u20 made Eclipse think it was no longer needed to pass the permgen flags to the VM since it was no longer called “Sun” but an “Oracle” VM.

I really wonder why these problems started with me now that I’m using windows 7, last week with Windows XP I had no problems at all (I got 2GB of Ram – before opening Eclipse I have 1GB free ) and this Eclipse WTP of mine is just the same as the other one (Copied and pasted the its folder), besides I got stupid projects in it, I mean, just have training and basic stuff so no real projects to cause such problems.

* Using the lastest JDK though

[...] is a decent amount. You can go with less, or more depending on how much free memory you have. See here for more details on Eclipse memory [...]

Darcio, that works too but has the disadvantage that any Java App you run will (potentially) use that much memory. Just something to be aware of.

I had a problem about OutOfMemoryError because of the Eclipse and I read this article but the suggest didn’t solve. I found another solution in the net and I am going to share with you.
On Eclipse select the menu Window>>Preferences>>Java>>Installed JREs

Select the version that you use and click on the button Edit

In field “Default VM Arguments” put for example:
-Xms512m -Xmx1g

It is really important that you rename your .ini file if your executable is not called “eclipse”. The changes will not be picked up otherwise.

Ahh thanks, I’ve been looking for a solution.

Hi Xam,

Subject – .ini file name must match the .exe file name and
not all versions of eclipse require separate lines for .ini.

Thanks for the info – it was great. I am running Eclipse Ganymede version 3.4.2 on a Windows XP box. The command line solution worked great for me but when I tried to add the commands to my eclipse.ini file they were never picked up – verifying the changes were made the way you indicate in your helpful solution. As it turns out I had changed the name of my eclipse.exe file to eclipse-3.4.2.exe. Thus, per

http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse.platform.doc.user/tasks/running_eclipse.htm

the init parameters will be read from a corresponding .ini file called eclipse-3.4.2.ini or you can specify a particular file name using the command

–launcher.ini (Executable) NEW
the location of the product .ini file to use. If not specified the executable will look for a file beside the launcher with the same name and the extension .ini. (ie eclipse.exe looks for eclipse.ini, product.exe looks for product.ini)

So, when I made this change and started Eclipse nothing happened – eclipse did not start up at all (my file had the commands on separate lines as you indicate in your solution). I changed my .ini file to be on one line and wham – Eclipse started just fine and the init parameter I had set in the .ini file were read in just fine.
