MySQL 5.0.46 enterprise with Mysql connector 5.1.7
Jboss- 4.2.3 GA
The are 2 Databases configured-JBossDB and AppDB. The *-ds.xml files have been configured to bind DefaultDS to Jboss DB and AppDS JNDI to AppDB
Both use <local-tx-datasource>
In a method call, 2 functions are being invoked
1. One function uses injected Entity manager (CMP) and calls em.persist and returns.
2. The other method uses EJB TimerService to create a timer - which in turn tries to create an entry in JBossDB
While doing this, its throwing the following exception stack:
EJBException -> IllegalStateException -> NestedSqlException -> Could not enlist in transaction on entering post-aware object
I am new to EJB world and the JTA world.
Is the above error because of a single transaction updating 2 different databases?
Will using xa-datasource help in resolving this issue?
thanks in advance
