Hi Guys,
I'm getting "java.lang.IllegalArgumentException: object is not an
instance of declaring class" in a webapplication. I think it's something
to do with the way CLOB is handled in Cayenne 3.0M4. The full stack
trace is at the bottom. I tried the Jboss-Oracle combination and I don't
get this exception on Jboss.
The environment details are:
Database - 10g
App server - Weblogic 9.2.2 on Solaris 10
Driver - Oracle Thin driver
Can you guys please advise on what are the likely cause of this?
Thanks a lot in advance.
Cheers,
Parth
