PK15137: GETRESOURCE(<D>) RETURNS A NULL URL ON AN IMPLIED DIRECTORY <D> IN A JAR

APAR status

• Closed as program error.

Error description

• When getResource(<D>) is called and an exact zip file entry for
  directory does not exist in a JAR, but the JAR contains entries
  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.
