[Hibernate-devel] Logging and Serilization and Applets (oh my)

[Urberg, J. <ju...@ve...>]

I've got an applet connecting to a session bean in JBoss.  The session bean
method returns an object mapped in Hibernate which happens to have a Proxy.
When I run the code outside a browser, everything works ok.  When I call it
from the browser, I get the stack included below.  I've tried putting
hibernate.jar, commons-logging.jar, log4j.jar and log4j.properties on the
applet's class path to no avail.  If I take the proxy off the class,
everything works a.o.k.

Anyone have any ideas why this is happening and/or how to fix it?

Thanks,
John
