WinMain events in JNI

Question

I am currently working on an application that uses DirectSound (JavaSound does not have the capabilities that I need). In order for the DirectSound buffer
to be filled at specified play blocks, I have to pass it the handle for my application. So far this is fine...I can get my java window handle easily enough from my JNI code and pass it to the DirectSound buffer.
Now comes the trouble...the callbacks that DirectSound makes are to WinMain. I cannot set a custom callback, I only give it the handle to my application. So I see two options
1. create an invisible window that exists for the purpose of these callbacks
- this will not work becase I cannot call my own JNI callback method for
refilling the buffer from a separate application (at least not without great
difficulty and the callback needs to be fast)
2. Somehow regsiter a callback within JNI with the JVM so that I will be notfieid if the JVM (which has the WinMain for the application) catches my events
Any ideas as to how to do the second or possibly another way to catch the WinMain events in my java app (within my JNI dll)?

Answer 1

there wont be events for session method, but u have to use these function modules
BDC_OPEN_GROUP
BDC_INSERT
BDC_CLOSE_GROUP
