JBoss XA wrapper for non-XA database drivers

[nadinec]

I'm using JBoss 3.2.3 with MySQL.

I'm currently getting lots of "[TxConnectionManager] Prepare called on a local tx."

Although I AM making use of JMS, I still get this warning when no MDB has been involved.
- I do have multiple entity beans participating in the transaction, however I thought that this was acceptable?
- I am making CORBA calls (directly using OpenORB)as well during this transaction and wonder if it has something to do with this...?

Anyway, my understanding of the problem is that I require XA support in my database driver. I understand that MySQL does not have XA support and therefore I am unable to use xa-database when configuring my datasource. Is there some other option available to me?

In my reading up, I have often come across the following:
"JBoss has a wrapper for non-XA JDBC connections to allow them to participate in XA transactions".

Please could you clarify this for me!
What are my options when using MySQL and making use of ditributed transactions?

Your options are:

1) Read the bloody FAQ

I must be stupid.

The FAQ at
http://www.jboss.org/faq
apologises for stale data and asks me to proceed with caution.

I am then presented with questions like
"What support exists in JBoss for JSP/Servlets ?"
and
"How is JBoss started ?"

OR.... this is not the resource you were recommending to me?

Thanks.

Apologies, I have now consulted FAQ on Wiki (JBossJCA) and have searched forums for XA issues.
Unfortunately I have not come across anything applicable as yet.

The warning I am getting is:
10:32:22,611 WARN [TxConnectionManager] Prepare called on a local tx. Use of local transactions on a jta transaction with more than one branch
may result in inconsistent data in some cases of failure.

Is this something that I have to live with if I use MySQL and JMS?
I would very much appreciate any help - just point me in the right direction.

Thanks again.

You can also use the main FAQ
http://www.jboss.org/wiki/Wiki.jsp?page=JBossFrequentlyAskedQuestions

It is an FAQ because it has been discussed many times, so search in this forum
or the JMS forum would be a useful excercise.
