RawPixelsBean is not transactional

[jmoore]

Similar to #410, RawPixelsBean is now throwing the following (following the fixes to #326):

ome.conditions.InternalException: Synchronization not active for TransactionSynchronizationManager
	at ome.tools.hibernate.SessionHandler.bindSession(SessionHandler.java:280)
	at ome.tools.hibernate.SessionHandler.acquireBindAndConfigureSession(SessionHandler.java:268)
	at ome.tools.hibernate.SessionHandler.newOrRestoredSession(SessionHandler.java:227)
	at ome.tools.hibernate.SessionHandler.doStateful(SessionHandler.java:165)

This has a combination of causes, but some background is available at: http://forum.springframework.org/showthread.php?t=12403

Basically, we were inappropriately using the Spring/JTA infrastructure. In fact, it's unclear why it was working at all. Will need to mark all beans for BMT, and slowly disable the non-JTA transactional support (see in-container.xml!hibernate.properties) which was making it semi-work.

r1038 provides the fix. Now the requirements for a bean are:

• Mark itself as @TransactionManagement(BEAN)
• Mark itself as @Transactional (with defaults for the bean)
• Mark any methods with @Transactional (where defaults need to be overridden)

May need to update #306.

Chris seems to be happy. Closing.

Re-opening as some methods within the RawPixelsBean? seem to need to be set to readOnly=false. Will investigate further. For the moment r1041 makes things work.

Passing off to Chris.

Resolved in milestone:3.0-Beta2.
