[Beginners Corner] - Proxy problem
by qler
Hello! I've a little problem over here. I want to create a simple stand-alone client, which creates a bean and invokes a method on it.
Here's the code for beans:
package bean;
|
| import javax.ejb.Stateless;
|
| @Stateless
| public class CreaterRemote implements Creater {
|
| public Foo create() {
| return new FooRemote();
| }
|
| }
package bean;
|
| import javax.ejb.Stateful;
|
| @Stateful
| public class FooRemote implements Foo, java.io.Serializable {
|
| private static final long serialVersionUID = 7316005043521549778L;
| private String name = "Hello!";
|
| public String print() {
| return this.name;
| }
|
| }
The code of the client:
package client;
|
| import java.util.Properties;
|
| import javax.naming.Context;
|
| import bean.Creater;
| import bean.Foo;
|
| public class Client {
| public static void main(String [] args) {
| try {
|
| Context jndiContext = getInitialContext( );
| Object ref = jndiContext.lookup("CreaterRemote/remote");
| Creater factory = (Creater)ref;
|
| Foo foo = factory.create();
|
| System.out.println(foo.print());
|
| } catch (javax.naming.NamingException ne){ne.printStackTrace( );}
| }
|
| public static Context getInitialContext( )
| throws javax.naming.NamingException {
|
| Properties p = new Properties( );
| p.put(Context.INITIAL_CONTEXT_FACTORY,
| "org.jnp.interfaces.NamingContextFactory");
| p.put(Context.URL_PKG_PREFIXES,
| "org.jboss.naming:org.jnp.interfaces");
| p.put(Context.PROVIDER_URL, "localhost");
| return new javax.naming.InitialContext(p);
| }
| }
The client class is situated in the other project with remote interfaces imported.
When i try to ru it, the following errors occure:

As I understand the server didn't generated proxy stub, as it must do. Maybe I have to change some settings on the server or something else?
I would be very grateful if somebody could help me.
