How to involve the external XA resource in the WL global transaction

Question

I wanted to know, if anybody has any knowledge of using external XAResource with
Weblogic transaction, at the client end. For example:
I create a Oracle Datasource and create a XAResource using unique xid. And would
like register with Weblogic Transaction service, to use in the global transaction
from client end.
Is it possible? if yes how. What are APIs.

Answer 1

The server-side connection obtained from the DataSource will enlist in
and be part of the global transaction. Client operations on the
connection will be performed on the server from which it was obtained.
WLS will register the Oracle XAConnection and enlist it in the global
transaction transparently.

Alex,
Thanks on your response.
The JNDI lookup for DataSource and get a connection from that datasource works
ok. But I want to make the external XAResource to participate in the WLS transaction.

Registering a resource on a client VM is not supported by WLS. It is
possible for a client to look up a remote DataSource from a server and
have connection operations participate in global transactions. However,
there are some limitations with this approach, such as result sets not
being available on the client.
