Hi, This is something I was going to ask anyway, and kinda ties in here.
If I develop a module, and bind it locally in JNDI, and this module requires database access. Can I have something like what JD drew below, and maintain tx context... eg: 1. client calls EJB with required tx 2. EJB calls my module 3. my module accesses db through DataSource 4. my module returns 5. EJB call completes, and tx commits make sense? I'm not introducing any new threads, so afaik it should be ok - but wanted to check? COuld someone confirm for me please? cheers dim ----- Original Message ----- From: "David Jencks" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, May 24, 2002 7:15 AM Subject: Re: [JBoss-user] Is it possible to use a Local Interface to an EJB from an MBean t hread in the same VM? > If you start a new thread, you've lost your transaction context.
