Javax.jms.InvalidSelectorException: The selector is invalid

Question

Hi ,
I am getting the following exception while running a JMS program
javax.jms.InvalidSelectorException: The selector is invalid: name !=Doctor
the code as follows
jndiContext = new InitialContext(env);
               TopicConnectionFactory factory = (TopicConnectionFactory) jndiContext.lookup("TopicConnectionFactory");
               //pubtopic = (Topic) jndiContext.lookup("topic/testTopic");
               subtopic = (Topic) jndiContext.lookup("topic/testTopic");
               TopicConnection conn = factory.createTopicConnection();
               tsession = conn.createTopicSession(false, Session.CLIENT_ACKNOWLEDGE);
               //publisher = tsession.createPublisher(topic);
               //String name = "Doctor";
               subscriber = tsession.createDurableSubscriber(subtopic,"testTopic","name != 'Doctor'",false);

Thanks for the reply.
I think you are correct if i give like following it is working fine.
String filter = "name in('doctor')";
subscriber = tsession.createDurableSubscriber(subtopic,"labtech",filter,false);

I have one more issue regarding durable subscriptions. when i publish a message in persistance mode like below
publisher.publish( myMessage,
          DeliveryMode.PERSISTENT,
          Message.DEFAULT_PRIORITY,
          180
the durable subscriber not able to get the message when he is in both states offline/online. I think in PERSISTENT mode the durable subscriber should receive the message at any cost other wise there is no meaning of guaranteed messaging. The above method is working fine in both offline/online states when the time value given as 0 or more than one second. I am running my application in JBoss 4.2.2GA.
