I have an app using Spring 2.5.6, OpenJPA 1.2.1, and WebLogic 10.3.2. I
specified a JTA datasource in the persistence.xml. I have a Spring
controller that calls my DAO class which uses the EntityManager. This
is working ok with respect to transactions. As my app is only going to
be reading the database, I would think I wouldn't need transactions.
However, because of one problem I'm having with traversing an
association path, I thought I would try to implement a transactional
service layer, and do the association walking within that layer.
So, I added a class with a "@Transactional" method and put that in
between the Controller and the DAO. Now, I'm seeing the following
exception stack trace:
--------------------
Caused by:
org.springframework.transaction.CannotCreateTransactionException: Could
not open JPA EntityManager for transaction; nested exception is
<openjpa-1.2.1-r752877:753278 nonfatal user error>
org.apache.openjpa.persistence.InvalidStateException: You cannot access
the EntityTransaction when using managed transactions.
