Lingo -- reconnecting a client to server

["Claude Montpetit [Trilliant]" <cl...@trilliantnetworks.com>]

Hi,

 * I have a client and server interacting with Lingo.
 * The client issues an async message and "listens" to obtain the answer 
back.
 * The client crashes.

Is there a way to restart my client and either resume waiting for the 
server response, or grabbing the answer if the server had completed? I 
understand that client uses a temporary queue to get the answer. So Is 
this possible with Lingo or will I do this with "pure" JMS queues or topic?
 
(still new to JMS/Lingo so I hope this question is not too off-topic)

The JMS contract basically says that temporary topics & queues only
survive for the duration of the duration of the JMS connection which
created them.

So to be able to handle clients crashing and coming back - just create
a queue per client and use that. i.e. rather than using a temporary
queue, just use a real queue - then any messages sent after the client
crashes will be redelivered on startup.

You just need to pass in the queue to use on the Lingo client - which
if none is provided, a temporary queue is created.
