java.lang.NoSuchMethodError: getMessageData

I got this error while trying to send to Websphere MQ 5.3 from WSAD 5.0. I use a statelesssession bean to send the message. Do you have any ideas?

java.lang.NoSuchMethodError: getMessageData

at java.lang.Thread.run(Thread.java:513)

Here's my code

InitialContext ctx = new InitialContext();
QueueConnectionFactory factory = (QueueConnectionFactory) ctx.lookup("jms/myQCF");
QueueConnection con = factory.createQueueConnection();
QueueSession session = con.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = (Queue) ctx.lookup("jms/myQ");
QueueSender sender = session.createSender(queue);
TextMessage message = session.createTextMessage("Hello");
sender.send(message);

Check to see if you have the latest fixpack installed. I corrected this error by installing fixpack 7.

Is this fixpack 7 for Websphere MQ 5.3 or WSAD 5.1?
