Hi all, i have a mapped Entity JPA tables to database with no transaction support and when a have a SSB with eg:

List method x(){
1- x = em.persist(obj);
2- y = em.find(obj.class,key);
3- z = em.createNamedQuery(queryXX).getResultList();
System.out.println(x+y+z);// at this line all ok
return z;
}

the lines 1,2,3 and 4 run perfect print objects in console, but when in a Backing Bean for JSF i access this SSB and call this method throws the folowing exception:

java.lang.RuntimeException: javax.transaction.RollbackException: [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted] [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted] Can't commit because the transaction is in aborted state
org.jboss.aspects.tx.TxPolicy.handleEndTransactionException(TxPolicy.java:198)

The problem is in a SSB ? JPA Implementation ? JSF ?

The registry in line "1- x = em.persist(obj);" is persisted in database and some operations is ok print in console, but when a return a object to JSF backing bean the error is throw.

JPA works with databases can´t work with transactions ??

Please helps, i using a Informix database with no transaction support.
Thanks.
