Hi,
I am trying to implement a publish/subscribe (topic) model with the help of JMS API's and JMS IQ manager. For both publisher and subscriber, I am having problems during session creation viz..
TopicConnection.createTopicSession(....);
I tried putting this in a seperate try-catch and validating if the topicsession object is null etc. I even tried catching the generic exception "Exception" but nothing happens. Surprisingly, the control directly goes to the "finally" block which I have in the end and here there is a null pointer exception (Exception in thread "main" java.lang.NullPointerException) in the statement " topicSession.commit();". I understand that the session variable has not been initialized and an exception has occured during initialisation.
But I wonder why this exception is not being caught in the catch block. Can some eGate JMS expert help me debug this problem??
Thanks in advance.
