MDB or MD Pojo.

garypinkham Jul 16, 2007 9:35 AM

What I have is a command line Pojo (either Java or .Net) that drops status messages on a queue. I want to pick up those status messages and save them to the DB and let my UI client know about them. I have this working in a different application (using Spring) but wanted to try this out with Seam. Since the rest of my app is Pojo I didn't want to use an MDB. When I read the docs for Message Driven Pojo's for JBoss I was a bit concerned as it seems that both ends know about each other.

So finally to the question. Does Seam provide any assistance with this? I've been trying to find the right place in the docs. I found stuff on publishing to a queue (not a topic) and that works great. Just trying to figure out the "Best/Recommended" way to receive the messages with Seam..

Thanks!
Gary

There are no "message driven POJOs" in Seam. Use an EJB3 MDB.

Thanks Gavin...

Just to confirm then.. I need to redo the seamgen and use an EAR deployment or is there another simpler way to get the EJB3 MDB into my existing WAR project?

Thanks again,
Gary

Well, yes, you need to deploy the MDB in an ejb-jar, so and EAR deployment is the easiest way to achieve that.
