Thank you very much Aaron and David for your reply.
As David suggested, I moved ojb related jars into repository and I added
them as dependency in my deployment plan then the class loader issue was
resolved. Now my class (WebSphereCETransactionManagerFactory) returns a
reference to TransactionManager.
Moving forward, the ojb could not find the data source when it trying to
look up it and I am getting errors like looking up DataSource
(java:comp/env/xmeta_defaultDS
javax.naming.NameNotFoundException: comp/env/xmeta_defaultDS). I am also
attaching my openejb.jar.xml, ejb-jar.xml and the database deployment
plan below.
This is the full stack trace of the errors.

Subject: Re: KernelRegistry does not return a reference to Kernel +
class loader issue
A couple of possibly helpful or misleading hints :-)
-- I dont' think that putting anything in lib/endorsed will lead to
joy :-) I think you need to put all the ojb related stuff in the
repository and get it into the same classloader by putting
dependencies to it in the same plan.
-- I don't see that you are using web apps, but if you are you
probably want to take all the jars out of WEB-INF/lib and put them in
the repository and use plan dependencies instead: this won't be
necessary in 1.1.
-- you might look in the spring module in trunk to see a similar way
of fishing out the transaction manager to integrate in another
framework. I'm not sure this code actually works at the moment.
-- be aware that jndi only works on threads that have gone through a
j2ee component. If you are trying to e.g. look up the datasource in
ojb from some startup thread such as a gbean constructor or doStart
method, jndi won't work. If you look up a datasource in jndi during
a call from an ejb, and the datasource is declared as a resource-ref
in your dd and plan, that should work. If you need the datasource in
a gbean you should use a gbean reference to the
ManagedConnectionFactoryWrapper gbean and get the datasource by
calling $getResource: see the system-datasource plan and the jdbc
timers for an example.
--Something like what you are doing ought to work: jetspeed 2 which
uses ojb seems to work fine in geronimo (after sufficient porting :-)
Hope this helps,
david jencks
