RE: Has anyone run OJB on WebLogic 8.1?
Problem solved:
I found a post by Armin on the archive (glad that's still online!)
recommending removing the T3ServicesDef from the startup class. I did this,
and no longer get the NotSerializableException.
Now I'm getting a different classloader exception, but not specific to OJB
(have to figure out the WL classloader, much different from JBoss).
Recommendation:
Change the sample startup class posted on the OJB website by removing the
T3ServicesDef member variable.

Here is some more information: in stderr (wasn't present in the log file)
there is a NotSerializableException caused by the Ojb startup class.
As you can see from the code below, the startup class does implement
Serializable. The only interface in OJB that it's implementing that is NOT
serializable is ODMGJ2EEFactory. But if this were a problem I'm assuming it
would have been noticed by others.
Here is the NotSerializableException stack trace from WL:

I tried following the instructions in the deployment documentation for OJB,
creating a startup class for WebLogic similar to the example posted on the
website.
I'm getting an error that WL is unable to bind the factory to JNDI. Then,
downstream of course I get errors that ojb/defaultODMG is not bound (we're
using the ODMG API).
Here's the error binding to JNDI, and code for startup classes. Am I doing
something wrong? We are trying to port to WL 8.1 for an urgent customer
request, so any help is appreciated.
