SessionBean does not pass information about exception thrown in handler method
------------------------------------------------------------------------------
Key: CORE-47
URL: http://galaxy.andromda.org:8080/jira/browse/CORE-47
Project: AndroMDA Core
Type: Improvement
Reporter: Sverker Abrahamsson
Assigned to: Chad Brandon
It have happened several times for me that when an exception thrown in a
handler method in the Impl class, the information about what acctually happened
is not passed on to the caller because the business method in the SessionBean
catch all Throwables and throw a new EJBExcption with only the message. The
stacktrace of where the original exception was thrown is lost.
Say that e.g. my handler method throws a NullPointerException because of some
bug. It is then important for me to know exactly where that happened. This
patch solves that:
