ClassCastException on SOAP calls upon redeployment

SourceForge Submitter: stephane_nicoll .
OS: Redhat linux 9
Java: SUN VM 1.4.1_02

The bug is reproductible with both JBoss 3.2.2 and
3.2.3RC1

We have an application, packaged as an EAR and
containing mainly:

• an EJB module JAR containing SessionBeans, Entity
  Beans and MDB
• an WSR module JARr containing a web service
  declaration
• Some librairies

The WSR module defines a web service that use a
SessionBean to process incoming SOAP calls

Eveything runs fine but when we hot-redeploy the EAR,
we have a ClassCastException and the web service does
not work anymore (we need to restart JBoss to fix this).

My guesses is that this is an Axis bug but I already
opened a bug @t apache without any feedback. We
discussed this issue in the JBoss-user mailing list see the
thread:

JBossNET hot deployment problem (ClassCastException)

This shows the classes / interfaces are OK after un
hotdeploy (see the thread for test output suggested by
Adrian)

What we have after the hot-redeploy at server side is
the following:
