Ole, Scott
I was the one who promised to work on IIOP. I thought it would help me
understanding the core code in JBoss and make some contribution at the same
time. Till now, I could only spend time investigating the
deployer/invokation code and studied somewhat about IIOP. As Marc previously
mentioned we have time until 30th August, I was a bit lazy as well.
But, its nice that you have already done lot of work (as I dont have any
experience in CORBA/IIOP). As I have time to contribute now, please let me
know how I can help you in continuing the IIOP efforts
(coding/testing/research etc).
Thanks,
tony
