Hello,

I run Hibernate 2.1.1 with JBoss 3.2.4RC1 on Windows XP.

I configure Hibernate as a JBoss SAR service using hibernatedoclet ant task.

I have the following attributes defined for Hibernate service.

<attribute name="TransactionStrategy">net.sf.hibernate.transaction.JTATransactionFactory</attribute>
<attribute name="TransactionManagerLookupStrategy">net.sf.hibernate.transaction.JBossTransactionManagerLookup</attribute>


I obtain the following exception (below). Interesting that the message is "Closing a connection for you" while stacktrace shows that it happend during getting connection by Hibernate from JBoss' DataSource.

The application works correcly and I don't know wheather I can ignore this exception.

Any help will be appreciated.

sincerely Olek

Yes, it seems that 3.2.X versions of JBoss are very touchy about when connections get closed. I had to put a finally clause in my ejb method that closes the connection:
