jboss 3.2.1 Local TM

We use jboss 3.2.1

jboss sheduler starts client procedure (call this procedure shd_Client_Procedure), than this procedure executes bean's procedure (call bean_Procedure). Bean's procedure makes changes in DB(oracle) and than returns execution to shd_Client_Procedure. On the results of execution shd_Client_Procedure I have to commit or rollback DB changes.

This bean is - BMT and stateful:

<ejb-name>SvrProcDoc</ejb-name>
 <home>svrProcDoc.ejb.interfaces.SvrProcDocHome</home>
 <remote>svrProcDoc.ejb.interfaces.SvrProcDoc</remote>
 <ejb-class>svrProcDoc.ejb.bean.SvrProcDocBean</ejb-class>
 <session-type>Stateful</session-type>
 <transaction-type>Bean</transaction-type>

In shd_Client_Procedure I start user transaction:

InitialContext jndiCntx = new InitialContext();
 UserTransaction utr = (UserTransaction) jndiCntx.lookup("UserTransaction");
 utr.begin();

When I begin to execute bean_Method, I try to monitor transaction status:

UserTransaction utr = (UserTransaction) jndiCntx.lookup("UserTransaction");
 utr.getStatus();

And I get javax.transaction.Status.STATUS_NO_TRANSACTION

And when I make changes in DB, and return to shd_Client_Procedure, and then execute bean's procedure to rollback or commit, I get

java.lang.IllegalStateException: No transaction.
 at org.jboss.tm.TxManager.commit(TxManager.java:147)
 at org.jboss.ejb.EnterpriseContext$UserTransactionImpl.commit(EnterpriseContext.java:477)
 at bars.kltoss.server.SvrPhaseW.commitPhase(SvrPhaseW.java:84)
 at svrProcDoc.ejb.bean.SvrProcDocBean.processDocCommit(SvrProcDocBean.java:121)

What is the problem? In documentation I found that if I work in same JVM with Jboss it is possible to use LocalTransactionManager
and I can spred my transaction like mine example.

Begin, Rollback or Commit transaction you have to do only in bean.

UserTransaction in bean you have to obtain from SessionContext.
SessionContext you can get in this bean's method:

public void setSessionContext(javax.ejb.SessionContext context) throws RemoteException { sessionContext = context; }

and then use it like this:

UserTransaction tx = sessionContext.getUserTransaction(); tx.rollback();

A very useful example I fount from this link:
