[ebxmlms-develop] Problem with getReceivedMessageIDs()

[Rajiv M. <rma...@ho...>]

All,

I am having problems querying the Request for ReceivedMessages.  I am 
sending and receiving messages from the same server, but I don't think this 
should cause a problem.  Once I send my message, I do see in the log as well 
as in the database that the message has been received.  The receivedmessage 
table has an additional row in it with the same messageID of the message 
that was sent.

In my class that queries for new messages, when I create a new Request 
object I pass null for the MessegeListener parameter.  Is that a problem?  
Also, the toMshURL I use is a bogus URL.  I'm just using this to listen for 
messages.  Does this need to be URL to a MSH server, if I'm just listening?  
When I query the the request for new messages, I get a zero length array 
back.  The class that queries the request also implements the 
MessegeListener Interface.  I have tried passing itself as a messageListener 
when I create the Request object.  When I take this route, the onMessage 
method is called when a new message is received, however if I send to 
messages back to back only the last message gets picked up?  I am sending 
the same message, but since they have different messageID's I don't think 
this should be a problem.  Again, the messages are stored in the 
receivedMessage table, but only one of them triggers the onMessage() method.

I have included some of the code.  Any help would be greatly appreciated.
