Hi, which version of jboss/tomcat are you using ?
normally in the latest one jboss2.1beta + embedded tomcat 3.2.
this error would go away if both are in the same EAR.
though it would still happen if they are not in the same EAR of if they
are deployed directly as jar.
It's an issue about classloader and object that are not marshalled from
one to an other.
I have send a couple of post to this mailing list regarding this subject
about a week ago, browse the archive for more details : www.mail-archive.com
Someone has made a fix but i don't know if it has been added to the CVS
tree.
regards,
Elouan
