Re: [JBoss-dev] Problems using UserTransaction
You can't use your own threads in ejbs. It's against spec and doesn't work with transactions, as you have discovered. david jencks On 2002.06.03 13:37:54 -0400 Patrícia Soares Canela wrote: > Hi there! > > I have this EJB, bean managed wich controls client's request and invokes > other beans. > I'm lauching threads to invilke these other beans. > > Supose that I have this transaction that needs to resort to three > diferent > beans; supose that the second bean fails and transaction must be rolled > back. > > Well, this isn´t happening!

RE: [JBoss-dev] Problems using UserTransaction
OK! So, do you know any way to implement cuncurrent processing with EJBs. If I cannot use threads, how can I perform the execution of several services in the same transaction? -Original Message- From: David Jencks [mailto:[EMAIL PROTECTED]] Sent: segunda-feira, 3 de Junho de 2002 19:04 To: [EMAIL PROTECTED] Subject: Re: [JBoss-dev] Problems using UserTransaction You can't use your own threads in ejbs.

RE: [JBoss-dev] Problems using UserTransaction
This may or may not workgive it a try and tell me if it works.
Use the TransactionManager directly.
void someEJBMethod()
{
InitialContext ctx = new InitialContext();
TransactionManager tm =
(TransactionManager)ctx.lookup("java:/TransactionManager");
Transaction tx = tm.getTransaction();
//...
//... Create your threads and pass in the tx as a parameter
}
// Thread code
void run()
{
tm.resume(this.tx);
//... do your stuff
}
Am I making sense?

Re: [JBoss-dev] Problems using UserTransaction
Another way would be using MDB. Examples in the docos.
Works fine for me.
