MQ (Messaging Queue) connection using Topics

I am trying to connect to Message Queue using JMS. This is topic based connection. Now, the problem is, I have 4 different topics to subscribe to. In this case, I created object of InitialContext, then did lookup for TopicConnectionFactory and received TopicConnectionFactory object, then created Topic connection (TopicConnection) object, and from that I created TopicSession object.

Using this TopicSession object, I created four Topic and TopicSubscriber object which intern will connect to mentioned topic.

But now the problem is that, the MQ configurator is saying that, he can see only two connections made to the first topic that I subscribe to. No other topic is connected. (I am not receiving any error anywhere).

So, does that mean that, once the first topic is created using one TopicConnection class, it will not accept anymore topic connection? Do I need to create all the above mentioned object seperately for all four topics?

I took the reference of IBM provided code which specify how to connect to MQ using one single topic.

It is sorta covered in the JavaRanch Style Guide.
