I am trying to use Terracotta to cluster web apps running on Oracle App Server. I've modified the java options in my OC4J instance. (An OC4J is a JEE container.) However, when I start up the OC4J, I get the following error...

Code:

We don't support Oracle App Server yet. Typically to support an appserver, we need to understand and weave ourselves into its classlaoding hierarchy - so not much work, but we haven't done it for the Oracle AppServer yet (coming soon though)....

Cheers

So, has anyone been successful in using Terracotta in OC4j 10g? IS there any effort at all at Terracotta for doing that? Thanks.
