JMS and load balancing

[Jorge Jimenez C]

Hi.   If someone knows a tutorial that cover this topic, please send me a link.   It is posible to configure load balancing over JMS and two app. servers ?   Each server must point to a diferent queue or it is a shared one ?   What happen if one server crashes with the messages that were not processed ? It is posible for the other server to process these messages ?   Thanks in advance.   JJ
