The issue here seems to be this:
I obtain a UserTransaction at the start of the method and in case of error, I
call rollback in catch block. But the rollback is intercepted by the
SeamPhaseListener which tries to begin a transaction and I get the error
" Could not start transaction:
org.jboss.seam.jsf.SeamPhaseListener.begin(SeamPhaseListener.java:571"
How do I disable SeamPhaseListener from starting a new transaction?
More Details
---------------
I am having issues creating a new UserTransaction in a jbpm process using
Hibernate. Am I missing anything in order to create a JTA User transaction and
then bind the Hibernate session within the transaction? Please advise
Any advice greatly appreciated
My Code
-----------
public String createXXXXX()
{
JbpmContext jbpmContext = null;
Session session = null;
UserTransaction tx = null;
try
{
jbpmContext = JbpmUtil.getJbpmContext();
session = HibernateUtil.getSession();
jbpmContext.setSession(session);
System.out.println("About to start tx");
tx = (UserTransaction)new InitialContext().lookup("java:comp/UserTransaction");
while ( ...) {
..... 1. Perform custom DB operations using session
2. Persist ProcessInstance, Task using the same session
// throw error to test rollback
}
} catch ( Exception e)
{
tx.rollback();
}
When Tx is rolled back, I expect that all DB operations and jbPM operations
shoudl be rolled back. Instead I see this strange behavior:
When I lookup the transaction from InitialContext, the trasnaction statuis is
already active!
**************** TX STATUS: 0
So, when I rollback the transaction I get the error:
java.lang.IllegalStateException: Could not start transaction
