Hi Sandeep,

If you are using Eclipse plugin, here are the simple steps...

1)Create a New ESB Project
File >> New >> Others >> ESB
 http://community.jboss.org/servlet/JiveServlet/showImage/2-567804-10508/1.jpg  http://community.jboss.org/servlet/JiveServlet/downloadImage/2-567804-10508/450-450/1.jpg 

Give an appropriate name to the project. Provide the Target Runtime and JBossESB Runtime.

2) You will see the designer UI.

3) Let's build a simple JMS Provider for this example.
- Click on Add >> JMS Provider
- Put the Name, Connection Factory and Channel ID. (This channel ID will be used later to listen to this provider)
- Specify the Filter with Destination Name and Type ('Queue' in this case)

4) Now, let's add a new Service to the ESB
Provide the Name and category for the Service.

- Add a JMS Listener to the Service.
- Provide a Name to this Listener. Also give the Channel ID used for the Provider.

- Now, you can add a list of Actions to this Service. (Action Pipeline)
- Let's create a custom java class file for this purpose. You can also use one of the many inbuilt classes.

*     +package myPack;+*+
     import java.io.BufferedReader;
     import java.io.InputStreamReader;
     import java.io.IOException;
     import org.jboss.soa.esb.actions.AbstractActionPipelineProcessor;
     import org.jboss.soa.esb.actions.ActionProcessingException;
     import org.jboss.soa.esb.helpers.ConfigTree;
     import org.jboss.soa.esb.message.Message;+

+     public class *ServiceClass* extends AbstractActionPipelineProcessor {+

+         private String info;
         public ServiceClass (ConfigTree config) {}
    
         public Message process(Message m) throws ActionProcessingException {
             System.out.println("Enter your name:");
             try{
                 BufferedReader br = new BufferedReader (new InputStreamReader(System.in));
                 info = br.readLine();
             }
             catch (Exception e) {
                 System.out.println("Error: " +e.toString());
             }
             System.out.println("Hello " +info);
             return null;
         }
     }+

Provide these Name and Class (myPack.ServiceClass in the above example) to the Action in the Service

5) Now create a deployment.xml file in jboss-esb's folder.

+     <?xml version="1.0" encoding="UTF-8"?>
     <jbossesb-deployment>
          <depends>jboss.esb:deployment=jbossesb.esb</depends>
     </jbossesb-deployment>+

6) Also, you will need to create the Queue. You can directly create a jbm-queue-service.xml in your esbcontent.

+     <?xml version="1.0" encoding="UTF-8"?>
     <server>
          <mbean code="org.jboss.jms.server.destination.QueueService" name="jboss.esb.destination:service=Queue,name=One" xmbean-dd="xmdesc/Queue-xmbean.xml">
                    <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer
                    </depends>
          </mbean>
      </server>+

THAT'S IT !!  :) 
Your first ESB Project is ready !!
