Ok I have oficially downgraded myslef to n00b after a large amount of previous success with seam.

Basically I am trying to use the entity manager from an external thread. I have the entity manager.

EntityManager em = null;

 try {
 jndi = new InitialContext();
 //TODO get name from settings
 EntityManagerFactory emf = (EntityManagerFactory)
 jndi.lookup("java:/myEntityManagerFactory");
 em = emf.createEntityManager();
 NrgOrder nrgOrder = em.find(NrgOrder.class, 1);
 nrgOrder.setState(NrgOrder.SEND_ERR);
 em.persist(nrgOrder);
 log.debug(nrgOrder.getState());
 em.close();
 } catch (Exception e) {
 e.printStackTrace();
 } finally {
 try {
 if(jndi!=null) jndi.close();
 } catch (NamingException e) {
 e.printStackTrace();
 }
 }

the myEntityManagerFactory is the same one as seam references (I think) as defined by the following...

<persistence>
 <persistence-unit name="nrg2">
 <provider>org.hibernate.ejb.HibernatePersistence</provider>
 <jta-data-source>java:/myDatasource</jta-data-source>
 <properties>
 <!-- <property name="hibernate.hbm2ddl.auto" value="create"/> -->
 <property name="hibernate.cache.use_query_cache" value="true"/>
 <property name="hibernate.show_sql" value="true"/>
 <property name="jboss.entity.manager.factory.jndi.name" value="java:/myEntityManagerFactory"/>
 <property name="jboss.entity.manager.jndi.name" value="java:/entityManager"/>
 </properties>
 </persistence-unit>
</persistence>


and...

<?xml version="1.0" encoding="utf-8"?>
<components>
 <component name="org.jboss.seam.core.init">
 <property name="debug">true</property>
 <property name="myFacesLifecycleBug">true</property>
 <property name="jndiPattern">my/#{ejbName}/local</property>
 </component>

 <component name="entityManager" class="org.jboss.seam.core.ManagedPersistenceContext">
 <property name="persistenceUnitJndiName">java:/myEntityManagerFactory</property>
 </component>

 <component name="org.jboss.seam.core.manager">
 <property name="conversationTimeout">300000</property>
 </component>

 <component class="org.jboss.seam.core.Ejb" installed="false"/>
</components>

I am able to load using the above snippet but no updates are taking place.

I am calling close() with no joy. I tried calling flush() but i get

14:17:30,375 ERROR [STDERR] javax.persistence.TransactionRequiredException: no transaction is in progress
14:17:30,375 ERROR [STDERR] at org.hibernate.ejb.AbstractEntityManagerImpl.flush(AbstractEntityManagerImpl.java:293)

14:17:30,375 ERROR [STDERR] at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:520)

If i try and use transaction EntityTransaction et = em.getTransaction();
et.begin(); I get...

14:19:00,156 ERROR [STDERR] java.lang.IllegalStateException: JTA EntityManager cannot access a transactions
14:19:00,156 ERROR [STDERR] at org.hibernate.ejb.AbstractEntityManagerImpl.getTransaction(AbstractEntityManagerImpl.java:316)

14:19:00,156 ERROR [STDERR] at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:520)

I am clearly missing something obvious so can someone point it out to me plesae.
