Hi Scott,
I have tried the tcptunnelgui but I'm not seeing anything at all?
Heres the url: URL url = new URL
("http://localhost:9080/ASTWebService/servlet/rpcrouter";);
I have the following params to tcptunnelgui 80 localhost 9080, is this
right?
This is an ejb that I'm trying to expose as a web service.
I created a small class that calls the ejb and only returns a string from
the complex type that I really want and have exposed it as a soap web
service but I'm now getting the following error from it:
Fault Code = SOAP-ENV:Server
Fault String = Exception from service object: Class
com/libertyit/ast/ASTSessionFacade violates loader constraints
java.lang.LinkageError: Class com/libertyit/ast/ASTSessionFacade violates

Heres the code:
package com.libertyit.ast;

import javax.naming.InitialContext;
import javax.naming.Context;

import java.rmi.RemoteException;
import com.libertyit.ast.entity.Policy;
/**

public class ASTWSWrapper {
/** Creates a new instance of ASTWSWrapper */
public ASTWSWrapper()
{
}
public String getPolicyExpirationDate(String aPolicyNumber) throws
Exception {
// get the JNDI initial context
System.err.println("Getting J2EE initial context");
java.util.Properties jndiProperties = new java.util.Properties();
jndiProperties.put("java.naming.factory.initial","com.ibm.websphere.naming.W
snInitialContextFactory");
jndiProperties.put("java.naming.provider.url","iiop://localhost:900/");
Context jndiContext = new
InitialContext(jndiProperties);//jndiProperties);
// lookup the EJB home
System.err.println("Looking up EJB Home");
Object homeRef =
jndiContext.lookup("com/libertyit/ast/ASTSessionFacade");
ASTSessionFacadeHome home =
(ASTSessionFacadeHome)javax.rmi.PortableRemoteObject.narrow(
homeRef, ASTSessionFacadeHome.class);
// create the EJB instance
System.err.println("Creating EJB");
ASTSessionFacade ejb = home.create();
// call the getQuote method
System.err.println("Calling getPolicyDetails");
Policy policy = ejb.getPolicyDetails(aPolicyNumber);
System.err.println(policy.getExpirationDate());
String expirationDate = policy.getExpirationDate();
// remove the EJB
System.err.println("Removing EJB");
ejb.remove();
return expirationDate;
}
}
Is this a circular reference, I added the home and remote interface to the
jar containing this class and created a dummy web module for this one then
ran the soapearenabler on it. Whats going wrong here?
Thanks for your help
Tim

Unfortunately, it's hard to help with the WAS implementation, since you
cannot just plug in a new build that has more specific messages. Have you
used a tool like TcpTunnelGui to capture the SOAP envelope from the call? I
am wondering exactly what is being de-serialized when this error occurs.
