MDB invocation error

[Rohit Parik]

Hi All,

Need some help with invoking an MDB on WLS. We setup everything by the book.
Cant understand what we are doing wrong.

Problem Definition : Failure to execute the Message Driven Bean deployed on
BEA Weblogic Server v7.0

Source code for the MDB
Source of MDB �

import javax.ejb.*;
import javax.jms.*;
import javax.naming.*;

public class BPmdbBean implements MessageDrivenBean, MessageListener
{

  MessageDrivenContext messageDrivenContext = null;
  public BPmdbBean ()
  {
    System.out.println("Inside the constructor...");
  }

  public void setMessageDrivenContext(MessageDrivenContext
messageDrivenContext)
  {
    this.messageDrivenContext = messageDrivenContext;
  }

  public void ejbCreate() throws CreateException
  {
    System.out.println("This is ejbCreate()...");
  }

  public void onMessage(Message inMessage)
  {
    TextMessage msg = null;
    try
    {
        if (inMessage instanceof TextMessage)
        {
            msg = (TextMessage) inMessage;
            System.out.println("MESSAGE BEAN: Message received: " +
msg.getText());
        }
        else
            System.out.println("Message of wrong type: " +
inMessage.getClass().getName());
    }
    catch (JMSException e)
    {
        e.printStackTrace();
        messageDrivenContext.setRollbackOnly();
    }
    catch (Throwable te)
    {
        te.printStackTrace();
    }
  }

  public void ejbRemove()
  {
    System.out.println("This is ejbRemove()...");
  }
}

Source of the Client �
import javax.naming.*;
import javax.jms.*;

public class msgClient
{
  msgClient msgClientObject = new msgClient();
  public static void main (String[] args) throws Exception
  {
    System.out.println("About to run client" ) ;

    String url = "t3://223.255.255.194:7001";

    java.util.Properties properties = System.getProperties();
    properties.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
    properties.put(Context.PROVIDER_URL, url);

    Context ctx = new InitialContext ( properties );
    QueueConnectionFactory factory = null;
    Queue queue = null;

     try
    {
      factory = (QueueConnectionFactory ) ctx.lookup
("java:comp/env/jms/NewQueueConnectionFactory");

      queue = ( Queue ) ctx.lookup ( "java:comp/env/jms/NewJMSQueue" ) ;
    }
    catch (NamingException e)
    {
      System.out.println("JNDI lookup failed.. " + e.toString());
      System.exit(1);
    }

    QueueConnection connection = factory.createQueueConnection();

    QueueSession session = connection.createQueueSession(false,
Session.AUTO_ACKNOWLEDGE);

    QueueSender queueSender = session.createSender(queue);

    TextMessage message = session.createTextMessage();
    for (int i = 0; i < 5; i++)
    {
      message.setText("This is message " + (i + 1));
      System.out.println("Sending message: " + message.getText());
      queueSender.send(message);
    }
  }

  public msgClient()
  {
    try
    {
      jbInit();
    }
    catch(Exception e)
    {
      e.printStackTrace();
    }
  }
  private void jbInit() throws Exception
  {
  }
}

The configurations on the Weblogic Server:
For the Connection Factory:
Name : NewQueueConnectionFactory
JNDI Name : NewQueueConnectionFactory
Client Id :
Default Priority : 4
Default Time To Live : 0
Default Time To Deliver : 0
Default Delivery Mode  : Persistent
Defualt ReDelivery Delay : 0
Messages Maximum : 10
Overrun Policy : Keep Old
(Not Checked) Allow Close In On Message
Acknowledge Policy: All
(Checked) Load Balancing Enabled
(Checked ) Server Affinity Enabled

The target server specified

Stores
Name : NewJDBCStore
Connection Pool : SamplePool


Servers
Name : NewJMSServer
Store : NewJDBCStore
Paging Store : none
Temporary template : none

Target server specified

Destinations
Name : NewJMSQueue
JNDI Name : NewJMSQueue
Enable Store: default
Template: none
Destination Keys : none

(The properties not mentioned all set to default values)

On execution of the client program error occurs.
The error is : Naming Exception

The class name should be specified in the environment properties file or in
applet parameter
This error occurs on reaching the code for lookup in the client code.

Any help is welcome.

Regards
Rohit
