XA-JMS with non-XA-JDBC

[lion78at]

Hello!

I am using in one transaction of a session-bean JMS (with JmsXA) and JDBC (with non-XA Oracle DataSource).

So I get the following warning:

[org.jboss.resource.connectionmanager.LocalTxConnectionManager$LocalConnectionEventListener] prepare called on a local tx. You are not getting the semantics you expect!

My questions now:
1. Is this a problem or can I neglect this warning?
2. Is there an non-XA-JMS-RA available and can/should I use it (I need transactions!)?
3. I know that there is a XA-Oracle-Datasource available, should I use it with the XA-JMS-RA?
4. Is my information right, that XA is for distributed transactions and that an (normal) non-XA-JMS-RA also supports transactions?

Thanks and greetings, Bernhard.

The warning is telling you that nonXA oracle
doesn't support two phase commit.

So you db update might fail, but the JMS part
could commit.
With XA oracle prepare is called first before
any commits to test whether the commit will
work on all resources.
