Servus Leute,

versuche mich gerade auf eine EJB mit Hilfe eines selbstgeschreibenen Clients zu connecten:

package helloClient;


import java.rmi.RemoteException;

import java.util.Hashtable;


import javax.ejb.CreateException;

import javax.naming.Context;

import javax.naming.InitialContext;

import javax.naming.NamingException;

import javax.rmi.PortableRemoteObject;


import commons.*;


public class HelloClient {


	public static InitialContext createInitialContext() throws NamingException {

		Hashtable env = new Hashtable();

		env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");

		env.put(Context.PROVIDER_URL, "jnp://localhost:1099");

		env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

		return new InitialContext(env);

	}


	public static void main(String[] args) {

		try {

			Context iniContxt = createInitialContext();

			System.out.println(iniContxt);

			Context contxt = (Context) iniContxt.lookup("java:comp/env/ejb");

			System.out.println(contxt);

			Object ref = contxt.lookup("helloWorldBean");

			System.out.println(ref);

			HelloHomeIF home = (HelloHomeIF) PortableRemoteObject.narrow(ref, HelloHomeIF.class);

			System.out.println(home);


			HelloIF helloIf = home.create();


			for (int i = 0; i < 100; i++) {

				System.out.println("\n*** *** *** ***");

				System.out.println("i: "+i);

				System.out.println(helloIf.getHello());

				Fahrzeug fzg = helloIf.search();

				System.out.println("Fahrzeug: "+fzg.hashCode()+" Fzg-Nr: "+fzg.getFzgNr()+" Reifen: "+fzg.getWheels());

				System.out.println("*** *** *** ***\n");

			}


			} catch (NamingException e) {

				e.printStackTrace();

			} catch (RemoteException e) {

				e.printStackTrace();

			} catch (CreateException e) {

				e.printStackTrace();

			} catch (Exception e) {

				e.printStackTrace();

			}

	}


}

Wenn ich mich nun auf meine Rechner Connecten will, bekomme ich folgende Fehlermeldung:

javax.naming.InitialContext@1690726

Als IDE verwende ich JbossIDE 1.6 und habe in den BuildPath des Projektes den folgende Libraries eingebunden:

• jnp-client.jar
• jboss-common-client.jar
• j2ee 1.4 Libraries (JBoss-IDE)
• JRE System Library (jdk)
• Web Services 1.0 Libraries (JBoss-IDE)

Die EJB läuft auf einem JBoss 4.0.5 und ist EJB2.1 konform geschrieben. Die Paketstruktur sieht folgendermaßen aus:

Hello

 |--> src

          |--> commons

                      |--> Fahrzeug.java

                      |--> HelloBIF.java

                      |--> HelloHomeIF.java

                      |--> HelloIF.java

          |--> helloBean

                      |--> HelloBean.java

          |--> helloClient

                      |--> HelloClient.java

          |--> META-INF

                      |--> ejb-jar.xml

                      |--> jboss.xml

Die ejb-jar.xml enthält folgendes:

<?xml version="1.0" encoding="ISO-8859-1"?>


<!DOCTYPE ejb-jar PUBLIC

'-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN'

'http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd'>


<ejb-jar>

	<description>Beispiel 1: Stateless session bean

	</description>

	<enterprise-beans>

		<session>

			<description>Hello</description>

			<ejb-name>hello</ejb-name>

			<home>commons.HelloHomeIF</home>

			<remote>commons.HelloIF</remote>

			<ejb-class>helloBean.HelloBean</ejb-class>

		<session-type>Stateless</session-type>

		<transaction-type>Bean</transaction-type>

		</session>

	</enterprise-beans>

</ejb-jar>

Die ejb-jar.xml enthält folgendes:

<?xml version='1.0' encoding='UTF-8' ?>


<jboss>

  <enterprise-beans>

    <entity>

		<ejb-name>hello</ejb-name>

		<jndi-name>helloWorldBean</jndi-name>

    </entity>

  </enterprise-beans>

</jboss>

Könnt Ihr mir sagen, was ich falsch mache?

Hat sich erledigt. Man benötigt nur die jbossall-client.jar.

PS: Hier kann dann zu.
