Author: chirino
Date: Wed Apr 25 10:20:28 2007
New Revision: 532413
URL: http://svn.apache.org/viewvc?view=rev&rev=532413
Log:
- Removed the transactionPolicy attribute from the RouteBuilder since this was
not actually configuring the inbound transaction policy as first envisioned.
This may come back in a different shape/form.
- JpaMessageIdRepository now starts it's own transaction if called from a non
transaction context.
- MockEndpoint now has a assertWait() method that can be used to wait for
messages to arive before assertions are made against those messages.
- Added some more tests and imporved that TransactedJmsRouteTest
- The JmsConfiguration now uses a CacheLevel of CACHE_CONSUMER by default since
this most efficient way to recieve messages from JMS.
