<DIV>hi,all</DIV>
<DIV> </DIV>
<DIV>I have a sender and i have a receiver. Sender pushes the messages,
apple ,orange ,banana to queue which is named "fruit"</DIV>
<DIV> </DIV>
<DIV> once the receiver gets the message "banana" and send the ack. i
want the sender to be noticed so it can send the message "banana" to the
queue</DIV>
<DIV> </DIV>
<DIV> you know, i mean, i want to ensure that the queue does always
contains banana ,apple and orange and if one message was got by the receiver
,the sender will push it to the queue</DIV>
<DIV> </DIV>
