Microsoft server-Java server over HTTPS

Help Requested:
Anybody ever tried communicate with Java server from Microsoft server over HTTPS using XML messaging?
1. XML message is attached with digital certificate and encrypted 128-bit using Microsoft APIs (C++, COM+). XML message is then sent out to the Java server URL via HTTPS.
2. Java server (java bean) receives the XML message. Session successfully established, authenticated. But the message format is not acceptable.
Any advise?
