[Advanced-java] JNI : Multiple Client Threads in Java APP using COM Server in DLL

[diya7874@xxxxxxxxx (diya prakash)]

Hello,

I have a Java application which calls in to a DLL.This
call basically creates a new C++ thread 
2.Which attaches itself to the JVM
3. and also creates a CCmdTarget object thereby
connecting to the COM Server through connection
points(OLE automation and the sorts!!!)

I have a dispatch Map which exposes a method called
MsgReceived; which is fired on receipt of a COM
message.In MsgReceived,I do a CALLBACK to the
respective java method using the jobject which made
the initial DLL call.


Something like

BEGIN_DISPATCH_MAP(CServerEvents, CCmdTarget)
	//{{AFX_DISPATCH_MAP(CServerEvents)
	DISP_FUNCTION(CServerEvents, "method MsgReceived",
MsgReceived, VT_ERROR,  VTS_VARIANT VTS_I4 )
	//}}AFX_DISPATCH_MAP
END_DISPATCH_MAP()

The PC Ref Stack will receive all API calls made from
multiple
threads by default.

The Problem:
However,multiple threads do not all receive messages
by default.

I would like different threads in one java application
to make API calls(which is fine) and receive the
respective message(which is the problem).

My question is 
1. Should i create a new C++ thread for each thread
that I create in Java...
   and should this thread in C++ register itself as a
seperate COM client?
2. Or should i somehow implement a mechanism such that
the Parent thread     receives all notifications from
the com server and forwards the messages to the
respective thread? If so,are you aware of any such a
mechanism?

3. How do i delegate the messages notifications to the
right client thread?

Please help!!!!Any pointers will be deeply
appreciated.

Thank you for all the valuable suggestions,in advance.
Diya
