This smells of a classloader problem. I'm no expert in this area, but if you have the same class loaded by two classloaders, you'll get a ClassCastException when an object of that class is passed between the objects instantiated from two different classloaders.
For example, if in one classloader, you have an object that does a new MyClass() and then you pass that object to a method on an object from a different classloader, which takes (MyClass obj) as a parameter, when that method is invoked, you'll get a ClassCastException, even if the class is loaded from the same JARs, the same .class file, or whatever. I'm not sure where the timing you've indicated would play into this scenario, but this smells like a classloader issue of some sort. I know in JBoss you can use a unified classloader, and you can get the embedded Tomcat that JBoss uses to also use the JBoss classloader - not sure if that would help in this situation (probably not, since you have different VMs). Hope this helps in some small way.

Jboss 4.0.5 tomcat 5.5.17 jvm 1.5.08 xfire 1.2.3 I'll describe my instalation: Jboss -> Stateless-Session userAuthorization -> Stateless-Session calculator tomcat (in differente JVM) front end to jboss Stateless-Session tomcat has in it's share class-loader all jboss-client jars (except jws), and then all xfire jars (in that order) When a user needs to run a service this needs to be done: Obtain a ticket from web-service userAuthorization The web-service obtains a ticket calling EJB userAuthorization Use this ticket to call calculator's methods (example add(ticket, num, num)) The web-service validates ticket against EJB userAuthorization call the corresponding calculator method The problem: The consumer obtain the ticket without problem When he tries to call the calculator method, the ticket validation gives a strange ClassCastException in Jboss generated Proxy. if I wait 60 seconds between the 2 calls all works fine (????) if I wait less than 60 seconds, the same problem appears. What I tested: I make a client calling directly jboss from java, all works ok I make a standard servlet deployed in my tomcat that receives an URL and does the two calls, it worked ok I make a WS-Client the problem appears I tried with soapui the problem appears Any ideas where or what to look for will be greatly apreciatted.
