Set the system property to enable remote EJB clients to receive nested or root-cause exceptions

 

You might want to code your application to perform a given action if a certain kind of exception is the root-cause of a failure and is nested within the exception that you receive. The default behavior in WebSphere Application Server might mask a nested or root-cause exception in your application.

 

Overview

The EJB container creates a TransactionRolledbackException exception for a remote client when it can create a RemoteException exception instead. With the RemoteException exception, the container does not lose the ability to have root-cause information nested inside the exception.

You can set the following JVM system property to true through the console for WAS: com.ibm.websphere.ejbcontainer.includeRootExceptionOnRollback This change enables the remote client to receive nested exceptions when a rollback occurs.

This property is applicable only for scenarios where the transaction in which the bean method is running was started by the container for this specific method invocation. All of the other scenarios must result in a TransactionRollBackException exception according to the EJB specification.
