    ****************************************************************
    A confusing exception can be thrown during a JSP request under
    load when the JSP Container is attempting to load the JSP
    class with the com/ibm/_jsp package.  If an error is thrown
    while loading the JSP class, the JSP Container will catch it
    and then attempt to load the JSP class with the org/apache/jsp
    package instead.  This can lead to the following error:
    com.ibm.ws.webcontainer.webapp.WebApp logServletError
    SRVE0293E: [Servlet
    Error]-[/TestApp/testPage.jsp]:
    java.lang.Exception: java.lang.Error:
    java.lang.NoClassDefFoundError:
    org/apache/jsp/_testPage (wrong name: com/ibm/_jsp/_testPage)
    

Problem conclusion

  • The JSP Container was modified to log a warning message
    and also log the exception caught while trying to load the
    original class.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.35, 8.0.0.10 and 8.5.5.3.  Please refer to the
