Make persistence exceptions more visible to client
--------------------------------------------------
Key: GERONIMO-4576
URL: https://issues.apache.org/jira/browse/GERONIMO-4576
Project: Geronimo
Issue Type: Improvement
Security Level: public (Regular issues)
Components: persistence
Affects Versions: 2.2
Environment: Linux, Windows
Reporter: Joe Bohn
Assignee: David Jencks
Priority: Minor
Fix For: 2.2
See http://issues.apache.org/jira/browse/GERONIMO-3907 for details of the
original problem. That core problem was resolved. However, upon resolution
it was mentioned that it would be beneficial to report more specific failure
information back to the client. From GERONIMO-3907:

Today if have tested the new Geronimo release 2.1.1 (published on 28.04.2008).
The problem is now fixed. If the server gets an error on trying a commit, this
error is now thrown to the web bean.
Exception text:
javax.ejb.EJBTransactionRolledbackException: Transaction was rolled back,
presumably because setRollbackOnly was called during a synchronization: Unable
to commit: transaction marked for rollback Root Cause:
javax.transaction.TransactionRolledbackException : Transaction was rolled back,
presumably because setRollbackOnly was called during a synchronization: Unable
to commit: transaction marked for rollback
Unfortunately there is no proper root cause attached to the exception. So the
cause can only be seen in the server console, but can not be reported to the
user. It would be very nice if you could change this in a later release.
Thanks for your help.

I agree that exceptions on the server side should not be thrown to the client
side since such exceptions types might not be known by the client. However, for
unit testing purpose, it is useful to attach the root cause to the
RollBackException. I have modified a few lines in
org.apache.geronimo.transaction.manager.TransactionImpl.java to attach the root
cause in case of RollBackException and it works for my unit testing purpose (I
have not enough background on the java transaction architecture topic to submit
a patch for production). It would be great to define a configuration parameter
that permits to provide the root cause to the client and keep the current
behaviour that does not by default.

It's useful for more than unit testing - it's essential to be able to inform
the client what's wrong with the request. I've added some examples of this to
https://issues.apache.org/jira/browse/OPENEJB-782 .
