-- Error during running JMS client --

Question

Hello ,i m novice in JMS,just trying to Implement my first JMS programming on WL8.1,I m getting error during Run client program
My client program is below :
package examples;
import javax.naming.*;
import javax.jms.*;
import java.util.*;
public class Client
public static void main(String[] args)throws Exception
     Properties props = System.getProperties();
     props.put(Context.PROVIDER_URL,"t3://localhost:7001");
     props.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
Context ctx=new InitialContext(System.getProperties());
TopicConnectionFactory factory=(TopicConnectionFactory)ctx.lookup("javax.jms.TopicConnectionFactory");
TopicConnection connection = factory.createTopicConnection();
TopicSession session=connection.createTopicSession(false,Session.AUTO_ACKNOWLEDGE);
System.out.println("Envi Veraibles" + ctx.getEnvironment().toString());
System.out.println("Object Retrived "+ctx.lookup("testtopic").toString());
Topic topic =(Topic)ctx.lookup("testtopic");
TopicPublisher publisher=session.createPublisher(topic);
TextMessage msg=session.createTextMessage();
msg.setText("This is a test message");
publisher.publish(msg);
I m getting error during running client ::
Exception in thread "main" java.lang.ClassCastException: weblogic.jms.client.JMSConnectionFactory  examples.Client.main(Client.java:23)
i think error is due to this line
Topic topic =(Topic)ctx.lookup("testtopic");
Pls Help me
Thnx in Advance ...

Answer 1

First of thanks for gave me a Reply.
(1) System.out.println("Object Retrived "+ctx.lookup("testtopic").toString()); this line is nothing just i wanted to check that program giving me a object or not .and output of this line is
Object Retrived weblogic.jms.client.JMSConnectionFactory@1f66cff
(2)Testtopic is not a object but it is JNDI name whichever i specified in webligic-ejb-jar.xml
(3)i added this line System.out.print("Second output"+ctx.getClass().getName()); and i got this output:
Second output javax.naming.InitialContext
but still i m getting same error
here i m describing my code for ejb-jar.xml
