unable to insert/update persist/merge using spring DAO - No JTA transaction found
My App is built on Spring 3.0.5 and deployed in JBoss 5.1.
My DAOs are working fine for any get or getAll operations on any of the tables but any inserts or updates does nothing. I do not see any exceptions in the JBoss logs either but I do see the below line when I enable debug on JBoss. Can you please tell me what I am missing?
I suppose my DAO is unable to create or reference a transaction for the save(object) operation which I have annotated as REQUIRES_NEW.
Here's my spring-jpa.xmlCode:17:10:01,505 DEBUG [AbstractEntityManagerImpl] Looking for a JTA transaction to join 17:10:01,520 DEBUG [AbstractEntityManagerImpl] No JTA transaction found
