Has anyone managed to successfully install Cocoon 2 (B2) on weblogic 6.1?
I followed the instructions that came with the distribution, but Cocoon
failed to load during deployment with the following errors:
<Dec 3, 2001 12:05:04 PM IST> <Error> <J2EE> <Error deploying application
cocoon
: Could not load cocoon>
