Hey Paul,
Glad to hear someone else is working on this too. We are using
Java1.3 on HP but I develop on NT. Right now we use Xalan Java
for our transformer but after messing around with Xalan C++ it
would be great to be able to make a native call since the
performance increase would be substantial.
I can get the app to work solo but, when I try to pass in the
data to my JNI implementation it crashes. I'm stuck at this
point trying to figure it out.

This seems like some
