Thanking you in advance

What is the build ID of Eclipse? Also what is the version of MyEclipse you are using?

[smanchika]

the Build id: 200408201200-3.8.1
MyEclipse version:3.8.1

[Scott Anderson]

Could you upgrade to 3.8.2? There were quite a few bug fixes and enhancements related to both struts and taglibs that will likely resolve the issue.

The release notes for 3.8.2 are here: http://www.myeclipseide.com/ContentExpress-display-ceid-46.html

Instructions for using the 3.8.2 update site are available here:
http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-4029.html

[smanchika]

I upgraded successfully to myeclipse 3.8.2 .
but even now when i start tomcat server it is switching to debug perspective and points to NumberFormatException.

I tried starting the server by closing the project ,then server starts fine..
but when i open the project and start the server..it is switching to debug perspective..

but no where in my project has red cross mark..so i am assuming that my application is error free.. i am not understading what is going wrong?

as i mentioned earlier that when i do “close project” all open files gets closed except struts-config.xml. when i click on some text in that file ,i get msg “An error has occurred see error log for more details”
and i get the following error in error log(only part of the log is copied)

why i am mentioning is
are these two situations related?

[Riyad Kalla]

When it switches to the debug perspective, is the debugger actually stopping at a random class and you can hit “Play” to continue, or is the app server dying completely?

I think there is something going on with the app server installed if that is the case. Also I cannnot reproduce the struts-config.xml problem to save my life. I wonder if you shoudl create a new workspace to get rid of any weirdness that might be going on…

[smanchika]

yeah when i switch to debug perspective ..it opens the integer.class and used to point at NumberFormatException(null). when i press”F5″ it goes on and stops at no class found error”GetIntegerAction.class” and after that
“InetAddressCachePolicy.class”.

Let me tell you that my application was giving a warning
“IWAE0010E Run-time Exception java.lang.OutOfmemoryError ….”

so i checked your response in this support forum and increased the memory by using

“c:\eclipse\eclipse.exe -vm C:\j2sdk1.4.2_05\bin\javaw.exe -vmargs
-Xmx128M -Xmx256M

now my application doesn’t show me OutOfMemory warning but when i try starting my tomcat server from ME .. it just not responding at all..
in error log(C:\eclipse\workspace\.metadata\.log) i get the following error

!ENTRY org.eclipse.jdt.debug 4 120 Oct 20, 2004 11:34:34.247

but when i start my tomcat server outside myeclipse,it runs fine.

[Riyad Kalla]

Something funky going on with the Eclipse debugger here… what JDK do you have setup to run Tomcat?

[smanchika]

JDK ——j2sdk1.4.2_05

[Riyad Kalla]

What is your Eclipse Build ID?

This is clearly an Eclipse debugger issue, so I can’t help much more than some hand holding right now… I’ll ask around.

[smanchika]

Eclipse Platform
——————-
Version: 3.0.0
Build id: 200406251208

MyEclipse
————
Version: 3.8.2
Build id: 200409171200-3.8.2

[Riyad Kalla]

This might be because you are using Tomcat 4 and not 5 (doesn’t support JSR 45 spec)… I’m checking on it.

[smanchika]

but this problem occurred just few days back.. initially i could able to start/stop tomcat server from ME..

[Riyad Kalla]

smanchika,
We need to check here to see if this is a workspace issue going on. Shut down Eclipse and try and restart it with a new workspace (or use File > Siwtch Workspace) and select any new directory to create new workspace in. Then configure Tomcat and try and start/stop it… did it wokr?

[smanchika]

yeah tried creating a new workspace and started the tomcat ,but still the same error…
i am attaching message the error log (C:\eclipse\newworkspace\.metadata\.log)

the struts-config.xml problem still exists in new workspace too.
