I have spent a whole week trying to solve a problem without success. Frankly, I don't know what else to do except to turn for help here.

For development:
JDeveloper
JbossAS
Window 2003 Server

Components:
Entity bean(AddressEntity.java)
Session bean(AddressFacade.java)
Session bean interfaces(AddressFacadeRemote,java, AddressFacadeLocal.java )
JSF page(create.jsp)
JSF backing bean (Create.java)

Deployment:
foopojo.jar contain POJO and persitence.xml
fooejb.jar contains Session bean classes and jboss.xml
odmweb.war contains: jsp files, backing beans, jboss.web, faces-config.xml, web.xml etc.
odmapp.ear contains: foopojo.jar, fooejb.jar, fooweb.war, application,xml and jboss-app.xml


application.xml contains

<module>
 <web>
 <web-uri>fooweb.war</web-uri>
 <context-root>fooweb</context-root>
 </web>
 </module>
 <module> <ejb>fooejb.jar</ejb> </module>
 <module><ejb>foopojo.jar</ejb> </module>
</application>

The application is deployed as EAR (fooapp.ear) to jboss-4.2.0.CR1


I have in my backing bean (Create.java):

public String addButton_action() {
 try {

 //NOTE: addressEntity is property in this class
 addressEntity.setCreatedBy(user.getUserName());
 java.util.Date timestamp = new java.util.Date(System.currentTimeMillis());
 addressEntity.setDateCreated(timestamp);
 addressEntity.setDateLastModified(timestamp);
 addressEntity.setVersion(1);
 addressEntity.setHits(0);
 getAddressFacadeRemote().createEntity(addressEntity);
 info("Address was successfully created.");
 } catch (Exception ex) {
 ex.printStackTrace();
 error(ex.getLocalizedMessage());
 }
 return "address_create";
 }

 public AddressFacadeRemote getAddressFacadeRemote() {
 if(this.addressFacadeRemote == null){
 try {
 Context ctx = new InitialContext();
 //NOTE: RemoteJNDIName is "fooapp/AddressFacade/remote" in the session bean AddressFacade;
 //NOTE: Next is Line# 236 as reported in the exception thrown
 this.addressFacadeRemote = (AddressFacadeRemote) ctx.lookup(AddressFacade.RemoteJNDIName);
 }
 catch (NamingException e){
 throw new RuntimeException(e);
 }
 }
 return addressFacadeRemote;
 }

Create.jsp is an input form
1. I start the page
2. Fill the form
3. Click a button to process the data
4. The system check for error but there is no error to display
5. The system throws the following error:

08:49:33,578 ERROR [STDERR] java.lang.ClassCastException: $Proxy117
08:49:33,593 ERROR [STDERR] at com.xxx.vmo.foo.pojo.address.Create.getAddressFacadeRemote(Create.java:236)
08:49:33,593 ERROR [STDERR] at com.xxx.vmo.foo.pojo.address.Create.addButton_action(Create.java:846)
08:49:33,593 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

I can't go past this error no matter what I try. I would appreciate, very much, is anyone would help.

Thanks in advance.
