I'm having a problem with trying to create a SFSB with an injected EntityManager that has an EXTENDED context: @Stateful(name="OrderService", mappedName="OrderService") | @Local(Order.class) | public class OrderBean implements Order { | | @PersistenceContext(type = PersistenceContextType.EXTENDED, unitName = "persistence") | protected EntityManager em; | Company company = null; | | @PersistenceContext(type = PersistenceContextType.EXTENDED, unitName = "persistence") | public void setEM(EntityManager em) { | this.em = em; | } | | public Company getCompany(Integer Id) { | company = em.find(Company.class, new Integer(1)); | return company; | } | | @Remove | public void remove(){} | | @javax.ejb.PostActivate | public void postActivate(){ | System.out.println("postactivating order"); | } | | @javax.ejb.PrePassivate | public void prePassivate(){ | System.out.println("passivating order"); | } | | public void doSomethingElse() { | System.out.println("Doing something else"); | } | | public Company getCompanyBack() { | return company; | } | } At first everything works great. I lookup the SFSB from a jsp and call getCompany() which returns me the company. I then stick the reference to the SFSB interface into the http session. I hit another jsp which get's the SFSB interface from the session and calls getCompanyBack() and all is well. I can even walk lazy collections on the company with no problem. However, if I wait a while, the SFSB will passivate without error: 2006-08-03 09:56:12,987 DEBUG [org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager] Attempting to passivate; id=4sg3q-kqtq3k-eqfaw0yg-1-eqfaxk9s-7 | 2006-08-03 09:56:12,987 INFO [STDOUT] passivating order | 2006-08-03 09:56:12,987 DEBUG [org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager] Saving session state to: D:\jboss\jboss-4.0.4.GA.P1\server\default\tmp\sessions\OrderService-eqfax4z0-6\4sg3q-kqtq3k-eqfaw0yg-1-eqfaxk9s-7.ser | 2006-08-03 09:56:13,222 DEBUG [org.hibernate.impl.SessionFactoryImpl] serializing: 2c90839a0cd4b626010cd4b62e660000 | 2006-08-03 09:56:13,222 DEBUG [org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager] Passivation complete; id=4sg3q-kqtq3k-eqfaw0yg-1-eqfaxk9s-7 Then I try to hit the jsp page again, and it throws up trying to call getCompanyBack() complaining that it cannot find the SFSB: 2006-08-03 10:02:38,065 DEBUG [org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager] Attempting to activate; id=4sg3q-kqtq3k-eqfaw0yg-1-eqfaxk9s-7 | 2006-08-03 10:02:38,065 DEBUG [org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager] Reading session state from: D:\jboss\jboss-4.0.4.GA.P1\server\default\tmp\sessions\OrderService-eqfax4z0-6\4sg3q-kqtq3k-eqfaw0yg-1-eqfaxk9s-7.ser | 2006-08-03 10:02:38,112 DEBUG [org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager] Removing passivated state file: D:\jboss\jboss-4.0.4.GA.P1\server\default\tmp\sessions\OrderService-eqfax4z0-6\4sg3q-kqtq3k-eqfaw0yg-1-eqfaxk9s-7.ser 2006-08-03 10:02:38,190 DEBUG [org.hibernate.impl.SessionFactoryObjectFactory] lookup: uid=2c90839a0cd4b626010cd4b62e660000 | 2006-08-03 10:02:38,190 WARN [org.hibernate.impl.SessionFactoryObjectFactory] Not found: 2c90839a0cd4b626010cd4b62e660000 | 2006-08-03 10:02:38,190 DEBUG [org.hibernate.impl.SessionFactoryObjectFactory] {2c90839a0cd4b656010cd4b65da40000=org.hibernate.impl.SessionFactoryImpl@1cbcc56} | Then there is a long exception ending in: Caused by: java.io.InvalidObjectException: could not locate session factory by uuid [2c90839a0cd4b626010cd4b62e660000] during session deserialization | at org.hibernate.impl.SessionFactoryImpl.deserialize(SessionFactoryImpl.java:1038) | at org.hibernate.impl.SessionImpl.readObject(SessionImpl.java:1866) | ... 76 more I was using JBoss 4.0.4.GA-Patch1, then I tried the same install with EJB-3.0_RC8-FD installed on top, which also didn't work. If I remove the EntityManager from the SFSB, (and use other parts of the SFSB) then it works as expected, passivating and activating. I even tried making the em transient and marking it @Transient, but it yeilds the same error. I've looked around and done some reading, and it seems unclear if I should be able to do this with an EXTENDED context in an SFSB, but I'm following the example here: http://docs.jboss.org/ejb3/app-server/tutorial/extended_pc/extended.html Any help would be appreciated. Can this be done, is it not fully implemented yet? Is there a work around? Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962920#...
