Run-time exception java.lang.OutOfMemoryError occurred during validation. The validator being run was JSP Validator and the message thrown was .

what validator can cause this? what is the solution?

atmuc,

Could you please post all the information requested in Posting Guidelines?

As a top off suggestion, increase the memory given to the JVM while starting eclipse use: eclipse.exe -vmargs -Xmx512m

Though we really need the above questions answered to address your issue correctly.

Best,
Brian.

What toolsets were you using? (JSF, Struts, etc)

[Ufuk COBAN]

struts and jstl

Eclipse probably really is legitimately running out of memory since the default heapsize for Java applications is quite small for such a large application. Can you try restarting Eclipse with these arguments and see if that remedies the problem:
eclipse.exe -vmargs -Duser.language=en -Xms128M -Xmx512M

[Paul Devine]

I’m frequently running into this problem. A friend of mine is too. I’ve been running with -Xms512M -Xmx768M, my friend runs with a heap up to 1Gb. I’m running Eclipse 3.1, MyEclipse 4.0.2. I haven’t tracked Eclipse memory usage over time. At this point I’m not sure what to do other than try disabling MyEclipse.

We also have the OutOfMemoryError when using MyEclipse 4.02
It seems that compiling / validating a huge amount of jsps causes the problem.
Please fix this, I have to restart my eclipse multiple times a day.

I’m currently using 768 MB of heap.

kind regards.

[Scott Anderson]

All,

The issue is often not the heap itself but the Perm space for classes. Please try these startup arguments:
eclipse.exe -vmargs -Duser.language=en -Xms128M -Xmx512M -XX:PermSize=64M -XX:MaxPermSize=128M

That should do the trick. Oh, and 4.0.3 had enhancements for JSP compilation so you should update if you haven’t already. Please see the announcement here: http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-9793.html

[Florian Simon]

Thank you that works perfect!

kind regards,

This is due to the fact that your workspace is overloaded. As a solution give a new workspace while starting MyEclipse and it should be fine.
