[xmlblaster] question about queue in xmlBlaster

["zhang zhi wei" <zzwzyz at hotmail.com>]

Question 1:
1. 
run the  "java HelloWorldPublish -numPublish 100 -persistent true" 
command, and then 
in the XB_ENTRIES , there are two queues:  
msgUnitStore_xmlBlaster_10_0_0_239_3412Hello and 
history_inforMessaging_10_0_0_239_3412Hello
2. run  "java HelloWorldSubscribe -session.name joe/2  
-dispatch/callback/retries -1 -multiSubscribe false 
-dispatch/callback/pingInterval 2000 -interactiveUpdate true 
-historyNumUpdates 0 "
  two more queue are created :
   callback_nodexmlBlaster_10_0_0_239_3412clientjoe2 and
   subject_nodexmlBlaster_10_0_0_239_3412clientjoe
   
   the first queue is used for  callback queue , 
   what's the purpose of the second queue, say   
subject_nodexmlBlaster_10_0_0_239_3412clientjoe ?
   and what are the contents of the   
subject_nodexmlBlaster_10_0_0_239_3412clientjoe??
   
Question 2;
  The real message is in msgUnitStore 
  and history queue and callback queue are only references to real 
message.
  
  the question is :
    when a publisher publish a message, will the message be fist put into 
msgUnitStore,
    and then callback queue , and then history queue?
    
  I have see the doc in the requirements directory and still was puzzled 
by this procedure can you explain this to me?
