The documentation for weblogic, as shown at:
http://e-docs.bea.com/wls/docs60/ejb/EJB_deployover.html
.. talks about the class loader issues I mentioned, in particular the
section on Diagnosing ClassCastException errors it states:
"To correct such ClassCastException errors, EJB and servlet developers
must ensure that no two classloaders ever load an identical class.
Specifically, you should always ensure that EJB classes reside only in the
deployed EJB .jar file or EJB directory, and that they are not included in
other EJB .jar files or classpath definitions."
If we assume that EJB classes includes the interfaces, and take into account
the fact it talks about servlets and this particular error in the lines
immediatly above.. my reading of it is that it's saying don't include EJB
classes in the web app either.. (Although if someone thinks I'm
misinterpreting, I'm more than happy to believe that given a reasonable
reason :)
Any thoughts?
