Web service ClassCastException in the generated Tie class

Question

I got the above exception when making a request from a client to an EJB webservice. The exception is in the generated tie class on the server side.
I narrowed down the problem to this:
In my function call in the tie class: (now call MyFunction):
a function in the tie class is generated:
private void invoke_MyFunction(StreamingHandlerState streaminghandlerstate) throws Exception{
In this function, there's line:
((MyEJBInterfaceClass)getTarget()).MyFunction(...)
Where MyEJBInterfaceClass is the name of the remote interface, which has MyFunction declaration in it.
the getTarget() function is from TieBase class that the MyEJBInterfaceClass_Tie extended.
The error is generated because getTarget() did not return an instance of MyEJBInterfaceClass.
So, there must be some error in the generated code when I use the deploy tool to deploy my webservice.
Could someone please shed some light?
Sun, please fix your bugs. There are so many bugs that I found when using your server (App Server 8).
From not releasing the context resource properly to not lookup properly using the context, to randomly generate bad client.jar file to this error.
Very disappointed.

Hello again
I tried to reproduce your problem and could not so there must be something different than the following steps :
1. Create the interface MyIntf.java
package ejb;
public interface MyIntf extends java.rmi.Remote {
public String sayHello(String toWho)
throws java.rmi.RemoteException;
2. Create the EJB impl
package ejb;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import java.rmi.RemoteException;
public class MyEjb implements MyIntf, SessionBean {
SessionContext sc = null;
public MyEjb() { }
public void ejbCreate() throws RemoteException {
System.out.println("In MyEjb::ejbCreate !!");
public void setSessionContext(SessionContext sc) {
this.sc = sc;
public void ejbRemove() throws RemoteException {}
public void ejbActivate() {}
public void ejbPassivate() {}
public String sayHello(String toWho) {
return "hello " + toWho;
3. Create the config.xml (slightly modified from yours)
<?xml version="1.0" encoding="UTF-8"?>
<configuration xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
<service
name="MyEjbIntfService"
targetNamespace="http://java.sun.com"
typeNamespace="http://java.sun.com"
packageName="ejb">
<interface name="ejb.MyIntf"/>
</service>
</configuration>
4. Invoke wscompile
javac -d build ejb/MyEjb.java
wscompile -define -mapping build/mapping.xml -d build -nd build -classpath build config.xml
5. look at wsdl, there is nothing line MyIntfSoapPort like you had
in particular
<portType name="MyIntf">
complete wsdl is :
<?xml version="1.0" encoding="UTF-8"?>
<definitions name="MyEjbIntfService" targetNamespace="http://java.sun.com" xmlns:tns="http://java.sun.com" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
<types/>
<message name="MyIntf_sayHello">
<part name="String_1" type="xsd:string"/></message>
<message name="MyIntf_sayHelloResponse">
<part name="result" type="xsd:string"/></message>
<portType name="MyIntf">
<operation name="sayHello" parameterOrder="String_1">
<input message="tns:MyIntf_sayHello"/>
<output message="tns:MyIntf_sayHelloResponse"/></operation></portType>
<binding name="MyIntfBinding" type="tns:MyIntf">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc"/> <operation name="sayHello">
<soap:operation soapAction=""/>
<input>
<soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" use="encoded" namespace="http://java.sun.com"/></input>
<output>
<soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" use="encoded" namespace="http://java.sun.com"/></output></operation></binding>
<service name="MyEjbIntfService">
<port name="MyIntfPort" binding="tns:MyIntfBinding">
<soap:address location="REPLACE_WITH_ACTUAL_URL"/></port></service></definitions>
6. Package in deploytool.
this is the webservices I got from the assembly tool.
<webservices xmlns="http://java.sun.com/xml/ns/j2ee" version="1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://www.ibm.com/webservices/xsd/j2ee_web_services_1_1.xsd">
<webservice-description>
<display-name>MyEjbIntfService</display-name>
<webservice-description-name>MyEjbIntfService</webservice-description-name>
<wsdl-file>META-INF/wsdl/MyEjbIntfService.wsdl</wsdl-file>
<jaxrpc-mapping-file>mapping.xml</jaxrpc-mapping-file>
<port-component>
<display-name>MyIntf</display-name>
<port-component-name>MyIntf</port-component-name>
<wsdl-port xmlns:wsdl-port_ns__="http://java.sun.com">wsdl-port_ns__:MyIntfPort</wsdl-port>
<service-endpoint-interface>ejb.MyIntf</service-endpoint-interface>
<service-impl-bean>
<ejb-link>MyEjb</ejb-link>
</service-impl-bean>
</port-component>
</webservice-description>
</webservices>
So It works fine AFAIK, from your descriptrion, it seems that the wsdl file is incorrect so the problem starts far before the actual Tie generation. You wrote in a previous message that :
"In the wsdl file this is one of the places it shows: <portType name="MyEjbIntfSoap">"
This is where the problem is. Do you have any clue how you got that ? If you run again wscompile, do you have the same values ?
