Error description

  • When getResource(<D>) is called and an exact zip file entry for

    in subdirectories of <D>, getResourece(<D>) returns null; it
    should return the WSJAR URL for <D>.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of WebSphere Application Server.   *
    ****************************************************************
    * PROBLEM DESCRIPTION: Calling getResource(dirSpec) returns    *
    *                      null rather than the JAR URL for        *
    *                      "dirSpec", where argument "dirSpec" is  *
    *                      a directory specification that does     *
    *                      not exist in a JAR file visible to a    *
    *                      WAS application or WAR module class     *
    *                      loader, but the JAR contains class      *
    *                      and resource files in either the        *
    *                      "dirRes" directory, or in a sub-        *
    *                      directory of "dirRes".                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The WebSphere Application Server classloader searches for exact
    directory entries in JAR files and returns null when it does
    not find the exact directory entry. The JVM URLClassLoader
    returns the implied directory entry, so there is an
    incongruence between the JVM classloader and the WebSphere
    Application Server classloaders in the WebSphre Application
    Server class loading environment.
    

Problem conclusion

  • Apply APAR PK15137 to enable method getResource(dirSpec) to
    return the JAR URL for "dirSpec", rather then null, whenever
    an application JAR does contain an exact entry for "dirSpec",
    cut contains class and resource files in directory "dirSpec"
    or a subdirectory of "dirSpec."
    
    The fix for this APAR is currently targeted for inclusion
    in fixpack 6.0.2.7.
