Help! It works but it tells me it doesn't

[jezzalinkco]

The story so far is that I have setup the JBoss-3.0.0-tomcat-4.0.3 distribution and I've had an EJB 2.0 CMP Entity bean working, but then I decided to use XDoclet and after hours of fiddling I have got JBoss to deploy successfully again an I can use a servlet/jsp/ejb 2.0 CMP to add an entry into the database.

So whats my problem you ask, well here it is when I say it works successfully I mean that if you look in the database it is in there, but for some reason the page fails giving me a:

"javax.transaction.TransactionRolledbackException: Error getting application tx data map. Embedded Exception null; nested exception is: javax.ejb.EJBException: Error getting application tx data map. Embedded Exception null"

So basically I am wondering if anyone can shed some light onto this problem, coz I'm pretty much stumped.

Well, it could be worse. It could be not working and keeping that quiet.
Which database are you using here?

I am running into the same error. I can create the CMP objects, but accessing them afterwards, or accessing an object returned by a find method, causes the same error.

I'm running JBoss 3.0.0 w/ Jetty, and my backend is MySQL 3.23.49a.

I had the same problem.

It turns out that the transaction manager is getting confused .

Try removing all of your XDoclet transaction tags -- that fixed it for me.
