I user Pramati 1.1 build 1973.
Following is the class name of the DBConnection.
protonx.transaction.xa.XAConnectionImpl
It seems to be containers connection. But I have given Oracle's JDBC driver
as the JDBC driver in XA entry. I need oracle JDBC driver because I use
Oracle's features extensively. Can you tell me the way around this problem.
Will I have the same problem in WebLogic as well.
Please help

Most of the EJB servers offer you a connection pooling mechanism. This
mechanism basically
works like this:
* You request a database connection from the datasource
* The container looks in its pool if there is a DB Connection available.
If not, it
creates one
* The container wraps this DB connection with a "proprietary" DB
connection. All the calls
are delegated to the actual DB connection, except some (close() returns
the connection
to the pool instead of closing it, setAutoCommit() is a no-op, ...)
* The container returns you this "proprietary" DB connection.
You should thus print the class name of the DBConnection
(getClass().getName()), and look in
your EJB Server documentation to see if this class gives you the ability to
access the
underlying DB connection, which should be the real Oracle connection.
