Error description
WorkArea contexts are not serialized/deserialized, when making
inter ear
remote calls that remain on the originating server.

*                 users of Work Areas                          *
****************************************************************
* PROBLEM DESCRIPTION: java.lang.ClassCastException was        *
*                      thrown when using Work Areas            *

* RECOMMENDATION:                                              *
****************************************************************
When making a call from one ear to another when Work Areas
were being used, the work area contexts were not
serialized/deserialized across the call. In this case, the
call resulted in a call that did not leave the server. If the
application does not use shared libraries this can lead to a
ClassCastException. This is because the interceptors that
serialize/deserialize the Work Area contexts are not being
called for 'remote' calls that remain on the same server.
Problem conclusion
Classes LocalActivityContext, ActivityServiceClientInterceptor
and ActivityServiceServerInterceptor will be changed to
optionally allow serialization to take place even when the
remote call results in a call to the same server.
This behaviour will be controlled by a Custom Property. The
Custom Property is called
com.ibm.ws.activity.registerForLocal. When set to true this
new property will cause the interceptors to be called for all
calls. When the property is set to true, you may notice a
performance degradation due to the increase in interceptor
calls.
When the property is not set, or is set to any value other
than true, the interceptors will only be driven for remote
calls, as previously.
To set the property, follow these steps.
1.  From the Administrative Console, select Servers ->
Application Servers -> server name
2. Make sure the Configuration Panel is selected
3. Click Process Definition
4. Click Java Virtual Machine
5. Click Custom Properties in the Additional Properties panel
6. Press the New button
7. Enter com.ibm.ws.activity.registerForLocal in Name , and
true in Value
8. Press Ok and save the changes.
9. Restart the server for the change to be effective in the
server.
The fix for this APAR is currently targeted for inclusion in
fixpack 5.1.1.14. Please refer to the recommended updates page
for delivery information:

http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980

A new APAR will provide this function for WebSphere
Application Server Version 6.
