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

    October 19, 2004 at 2:44 pm #217990

    the Build id: 200408201200-3.8.1
    MyEclipse version:3.8.1

    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:

    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)

    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…

    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.

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

    October 20, 2004 at 11:46 am #218057

    JDK ——j2sdk1.4.2_05

    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.

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

    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?

    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.
