When using a client on AEs, the client will not WLM to a
WAS AE 4.0 or WAS 5.0 cluster.
Download Description
USERS AFFECTED:
WebSphere Application Server users of WLM, or Workload Management.
PROBLEM DESCRIPTION:
When using a client on AEs, the client will not WLM to a WebSphere
Application Server AE 4.0 or WebSphere Application Server 5.0 cluster.
Apply fix PQ75451 to the AEs client and server. A 4.0 AEs client
bootstrapping to the WebSphere Application Server 4.0 AE Admin Server or a
WebSphere Application Server 5.0 node agent or "foreign" cluster member.
Fails with NPE ( NullPointerException ). In this scenario the WLM code
also gets the request to route the request before any cluster information
has been resolved. Thus, it attempts to resolve to the AdminServer to get
the information directly. The AdminServer does not exist and messages
WWLM0028 and WWLM0020 are logged. An internal variable is not set in this
path (and should not be) which shortly thereafter gets dereferenced (thus
the problem) causing the NullPointerException in the
EJSRepositoryClient.
PROBLEM CONCLUSION:
A check was added to verify if a valid ServerGroup was returned from a
method call. If it was not, a new empty ServerGroup was created and
returned. Otherwise, a NullPointerException was returned, and that was
invalid.
