[xmlblaster] remainingLife

["liuwen" <liuwen at onewaveinc.com>]

Hi, all

I meet a question when using xmlBlaster, help me pls.

the message PublishQos is:
<qos>
   <expiration remainingLife='10000'/>
</qos>

publish such 10 messages

After a while,  the console Loged:
[2002-6-14 16:19:09 WARN  MessageUnitWrapper] Message 1 is expired, timeout event occurred - tests are missing!
[2002-6-14 16:19:09 WARN  MessageUnitWrapper] Message 2 is expired, timeout event occurred - tests are missing!

then, start the receiver ( login as zhangsan),  but it  doesn't work, the console loged:
