Error description

  • Issue with these 2 classes:
    com.ibm.webtools.runtime.StudioPervasiveServlet
    com.ibm.servlet.PageListServlet
    
    In WebSphere Application Server V6.1, both classes are
    packaged in the same com.ibm.ws.runtime_6.1.0.jar and it works
    fine.
    
    In WebSphere Application Server V8.5 the classes are packaged
    in two different jars:
    
    * com.ibm.webtools.runtime.StudioPervasiveServlet
    ---> WAS_HOME/plugins/com.ibm.ws.prereq.webtlsrn.jar
    
    * com.ibm.servlet.PageListServlet
    ---> WAS_HOME/plugins/com.ibm.ws.runtime.jar
    
    The "Import-Package" in the MANIFEST.MF of the
    com.ibm.ws.prereq.webtlsrn.jar need to be added to include the
    package "com.ibm.servlet".
    
    Note that the PageList Servlet custom extension is deprecated
    in WebSphere Application Server Version 8.5:

    * PROBLEM DESCRIPTION: The application server fails with a     *
    *                      NoClassDefFoundError when loading       *
    *                      the StudioPervasiveServlet              *

    * RECOMMENDATION:                                              *
    ****************************************************************
    The NoClassDefFoundError shown below is thrown because the
    package com.ibm.servlet is not imported by the OSGi bundle
    containing the StudioPervasiveServlet class.
    java.lang.NoClassDefFoundError:
    com.ibm.servlet.PageListServlet
    at java.lang.ClassLoader.defineClassImpl(Native Method)

    ...
    The JCM fails to define the StudioPervasiveServlet class
    because it cannot resolve the dependency on the
    PageListServlet class.
    

Problem conclusion

  • Apply APAR PI23501 to declare the import package dependency on
    com.ibm.servlet within OSGi bundle
    com.ibm.ws.prereq.webtlsrn.jar.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.5.5.4, 8.0.0.10, and 7.0.0.37.  Please refer to
