Problem with jms Message Selector

Hello all..
Im so desperate..Can anyone of u help me sort this problem..i have a bean that uses the timer service.on the ejbtimeout..i create a topic publisher and send a message to a topic.(topic name and connection factory have been successfully looked up).im using a message selector (userID) on the message im sending. Only users that have that id are supposed to receive the message.

On my client,it implements the messagelistener interface..the users logs with his/her userID.
Even that, a user with a different id receives the message�..

Hope the code will stretch the picture out..


BEAN (omitting exceptions)

Public void ejbtimeout(Timer timer){

String id=�03048660�
outputMessage=getAlertMessage(id);
System.out.println("The message is:"+outputMessage);


//topicConnectionFactory = new com.sun.messaging.TopicConnectionFactory();

Context ctx=new InitialContext();
topic=(Topic) ctx.lookup("java:comp/env/jms/TopicName");


topicConnectionFactory=(TopicConnectionFactory) ctx.lookup("java:comp/env/jms/MyConnectionFactory");

/* Create the connection.../
topicConnection = topicConnectionFactory.createTopicConnection();
/* Not transacted Auto acknowledegement */

topicSession = topicConnection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);


topicPublisher = topicSession.createPublisher(topic);
/*
* Non persistent delivery
*/
topicPublisher.setDeliveryMode(DeliveryMode.NON_PERSISTENT);


TextMessage msg=topicSession.createTextMessage();
msg.setText(outputMessage);
msg.setStringProperty("USERID",id);
topicConnection.start();

topicPublisher.publish(msg);

}


CLIENT:


Public class client extends MessageListener{

InitialContext ctx=new InitialContext();
topic=(Topic) ctx.lookup("java:comp/env/jms/TopicName");


TopicConnectionFactory=(TopicConnectionFactory) ctx.lookup("java:comp/env/jms/MyConnectionFactory");

topicConnection = topicConnectionFactory.createTopicConnection();
topicSession = topicConnection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
String filterProperty="USERID like '03048660' ";

topicSubscriber = topicSession.createSubscriber(topic,filterProperty,false);

topicSubscriber.setMessageListener(this);

topicConnection.start();



public void onMessage(Message message){
TextMessage msg=null;

try{
if (message instanceof TextMessage)
{
msg=(TextMessage)message;
System.out.println("Got Message:" + msg.getText());
JOptionPane.showMessageDialog(getContentPane(),msg.getText(),"Alert Service",JOptionPane.INFORMATION_MESSAGE);

}

}

catch(Throwable te){
te.printStackTrace();
}

}


}

When I run the program with ID :03048660, the expected output is obtained. the user receives the message.
But when I run (side by side) another instance of the same program with a different id, that user also receives the message..(although he is not supposed to receive it koz his ID is not 03048660)

Isnt the message filter working???plz help me
