[jboss-user] [EJB/JBoss] - Doing persistence operations in worker threads

Folks, I am running into a problem where I have come to a dead end after following several leads. I am launching an operation asynchronously in a separate thread which gathers some info and then starts persisting some entities. Problem is, I cannot seem to get anything written to the database. My current approach is to get the EntityManagerFactory and UserTransaction in my worker thread by doing a JNDI lookup: | InitialContext ctx = new InitialContext(); | EntityManagerFactory emf = (EntityManagerFactory)ctx.lookup( "java:/MyProjectEntityManagerFactory" ); | UserTransaction ut = (UserTransaction)ctx.lookup( "java:comp/UserTransaction" ); | | EntityManager em = em = emf.createEntityManager(); | As soon as the last line above is executed, I see the following message in my JBoss log file: | 2008-05-25 01:14:30,093 DEBUG [org.hibernate.impl.SessionImpl] opened session at | timestamp: 4963136594300928 | 2008-05-25 01:14:30,093 DEBUG [org.hibernate.ejb.AbstractEntityManagerImpl] Looking for a JTA transaction to join | 2008-05-25 01:14:30,093 DEBUG [org.hibernate.ejb.AbstractEntityManagerImpl] No JTA transaction found | All persistent operations seem to work, but nothing gets written to the DB. I see the following log messages in server.log: | 2008-05-25 01:21:20,718 DEBUG [org.hibernate.event.def.AbstractSaveEventListener] delaying identity-insert due to no transaction in progress | Is there anything I can do to start a JTA transaction? My environment is JBoss 4.2.2 and Seam 2.x Thanks. -Raj View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153204#...
