2.6.7 EJB WLM exceptions

There are two possible scenarios: - A failure that occurs during EJB processing

This triggers an exception. Normally, WebSphere WLM catches the exception and resends the failed request to another appserver in the cluster. This is the normal failover functionality of WebSphere EJB WLM. If, however, WLM cannot determine whether the transaction completed, it sends an exception to the application. - A failure that occurs during WLM processing

If the WLM mechanism is not able to handle the request it sends an exception to the application.
