Hi Dinesh,
The NullPointerException is a Geronimo bug. However, that is not the root cause of your problem. Have you looked at the following?

Caused by: java.lang.ClassCastException
       at com.Myapp.twe.logging.Log4jLogger.getLog4jLogger(Log4jLogger.java:65)
       at com.Myapp.twe.logging.Logger.getLogger(Logger.java:98)
       at com.Myapp.twe.logging.Logger.getLogger(Logger.java:132)
       at com.Myapp.twe.client.datamap.goodservices.impl.GoodServiceMappingImpl .<clinit>(GoodServiceMappingImpl.java:67)

Hi David..

Thanks for your response. The problem was with the deployment descriptor
and the issue is resolved....

But still i am not able to proceed. I get the following error..


Error: Operation failed: Error thrown during invocation

        null

        null

Can you tell me the cause for this error. By the way, I am using the M4
release of Geronimo.

Thanks,
Dinesh.G
