RE: [c2] class loading problem with a jdbc driver
I found that renaming the oracle library so that it ends in .jar instead of .zip did the trick. ;-) It works well! Thank you for the excellent advice!

Seems to be worked out. I had to place my oracle jar in the ext directory of JRE. A big thank you to the Cocoon 2 bug fixers for solving this problem!
