Hi Mike,
Just out of curiosity, what JVM are you using?
We're running XalanJ under JNI, and we've found that it crashes with the
1.3.02 Solaris JVM from Sun.
We had to revert to 1.2.2.
I'd be interested to hear how your adaptation goes, since one of the
reasons we decided to use Xalan was the availability of the C++ implementation.
