Dead-end with EJB3.0 and Sun's Java WebApp

Question

Hi,
Wondering if you can help me as I'm a bit stuck with my EJB3.0 remote connection using Sun's Java WebApp9.0 Server.
Quick over-view:
I have a Client.war file which contains my Servlets and the Remote interfaces for teh EJB and other 'client' classes
I have a EJB.jar which contains the EJBs with their interfaces
I need to make a remote connection to the CreateNewUserAccountBean (Stateless) which connects to the Uploader (Entity) Bean
I have tried to post all the relivent parts of the code, but it's quite hard to make sure I have everything.
My code gets as far as the [InitialContext ic = new InitialContext(this.getEjbRemoteProps());] then bombs out claiming it can not find the Uploader class (under EJB.jar)
As I say, there is rather a lost here and it's not the easiest to look through, but kust wondering if there are any glaring erroes in the code.
All the code bits.........
THESE ARE IN THE CLIENT WAR
============================
CreateUserAccountServlet
code:
     final private boolean uploadUserAccountDetails(CreateNewUserAccountBean crUsrAccBean) {
          System.out.println("uploadUserAccountDetails()");
          try {
               System.out.println("point 1");
               ICreateUserAccountManager crUsrAccMan = new CreateUserAccountManager();
               isSuccessful = crUsrAccMan.uploadAccountDetails(crUsrAccBean);
          } catch (NamingException e) {
               e.printStackTrace();
               isSuccessful = false;
          return isSuccessful;
CreateUserAccountManager
code:
     final public boolean uploadAccountDetails(CreateNewUserAccountBean crUsrAccBean) throws NamingException {
          System.out.println("point 2");
          IRemoteEjbConnector remEjbConn = new RemoteEjbConnectionManager();
          ICreateAccountRemote createAccRem = remEjbConn.createUserAccountRemoteConnection();
          createAccRem.setFirstname(crUsrAccBean.getFirstname());
          isValid = remEjbConn.uploadAccountDetails(createAccRem);
          return isValid;          
RemoteEjbConnectionManager
code:
final private Properties getEjbRemoteProps() {
          Properties props = new Properties();
          // To be put into a Properties file!
     props.setProperty("java.naming.factory.initial", "com.sun.enterprise.naming.SerialInitContextFactory");
     props.setProperty("java.naming.factory.url.pkgs", "com.sun.enterprise.naming");
     props.setProperty("java.naming.factory.state", "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");
     props.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
     props.setProperty("org.omg.CORBA.ORBInitialPort", "3700");          
          return props;
     final public ICreateAccountRemote createUserAccountRemoteConnection() throws NamingException {
          System.out.println("point 3");
          InitialContext ic = new InitialContext(this.getEjbRemoteProps());
          System.out.println("point 4");
          // ##### SEEMS TO ONLY GET THIS FAR, THEN BOMBS OUT! #####
          ICreateAccountRemote createAccRem = (ICreateAccountRemote) ic.lookup("createNewUserAccountEjb");
          System.out.println("point 5");
          return createAccRem;
THESE TWO ARE IN THE EJB3.0 JAR
===============================
CreateNewUserAccountBean
code:
     @Stateless (mappedName="createNewUserAccountEjb")
     @Remote ({ICreateAccountRemote.class})
     public Uploader findByPrimaryKey(String fname) {
          Uploader uploader;
          try {
               EntityManager em = emf.createEntityManager();
               uploader = (Uploader)em.find(Uploader.class, fname);
               em.close();
               return uploader;
          } catch (Exception ex) {
               ex.printStackTrace();
               uploader = null;
          return uploader;
ICreateAccountRemote
======================
code:
@Remote
public interface ICreateAccountRemote {
public String getFirstname();
public void setFirstname(String sFname);
public boolean createNewUserAccount();
public Uploader findByPrimaryKey(String name);
Uploader
code:
     @Entity
     @Table(name="tbl_user_details")
persistence.xml (under EJB.jar)
================================
code:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

Any help would be fantastic, cheers!!!

It has been deployed, incorrectly.
it's in the ejb.jar which is deplyed under the 'Applications/EJB Modules' in Sun's WebApp 9.0.it's still incorrect - the app server is telling you so.
I don't know if there is any other config that needs to be done with the WebApp to tell it where the WebApp .war should look to find the EJB Module?I use weblogic, so I don't know. Without seeing anything else, I'd say it's not packaged correctly. You think that class is available, but the app server disagrees with you. Believe the app server and figure out where you've gone wrong. Check your assumptions.
