I agree this is an important feature. I will make the ConnectionFactory
pluggable so that you can implement your JNDI Version.
I will include the fix in the next release (i hope to get it out within
1 or 2 weeks).
I'm interested in your JNDI based implementation. Would you mind to
contribute it ince it is finished? We could include it in the OJB
Codebase.

Yes, my hack won't behave in controlled environments! Do you have sample
code or a link to some information how to do these things properly?
Of course I want to integrate OJB smoothly in J2EE environments.

I have been thinking of this too, but there are so many priority 1
topics on my list, that it will take some time...

a question:
Will you use EntityBeans? If so, did you have a look at the OJB EJB
sample in package test.ojb.ejb ? It contains my suggestion for using OJB
for BMP EntityBeans.
