Are you sending a text message here ? - You could try and  
programmatically use
a queue browser to inspect the queue, just to make sure the message is  
really there.

Scratching my head here. Is your receiver connected to the same broker ?
This is where I am wondering what role Websphere has to play in your you have a bridge configured ? Are you expecting  
messages to travel
across from AMQ to Websphere ?

I don't quite get that comment. Do you mean a message with the same  
content ?
However, every time you the send method, technically new message is  
and sent. No message broker i know looks into the message to check  
that message already has been sent. IMHO this would belong into the  
or better the mediation layer, where you could apply an idem potent  
pattern, if necessary.
