I am not able to resolve this error.
What is the reason for this and the possible solution ?
I am using EJB3.0 and JBoss Application Server


jndi.properties

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost:1099

My Session Beans Are Somewhat like this

@Stateful
public class userSession implements userSessionLocal, userSessionRemote {
    
    private String id;
    private String username;

    public String getId() {
        return id;
    }

    public String getRole() {
        return role;
    }

    public String getUsername() {
        return username;

    public void set(String id, String username, String role) {

jboss.xml

when i am running this code
I am getting an exception

package test;

        Context ctx = new InitialContext(properties);
        Object objref = ctx.lookup("ejb/userSession");
        userSessionLocal user = (userSessionLocal)PortableRemoteObject.narrow(objref, userSessionLocal.class);
        try
        {
            user.set("0000", "Prateek", "Admin");
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

    }
}

I am using Netbeans6.9.1 and have not added any ejb-jar.xml
I have checked it on, but not able to find any solution.



Thanks
