I think one should scream louder...it is necessary to get JNI working with
major features of C++ if people wants both Performance with C++ apps AND
Java language interface....
So bad luck for me, I will have no choice if someone needs JDK 1.3 but to
remove exceptions from DOM....or do not support JDK 1.3!!
Is there a place/web or Sun site where to complain about this??
Regards
Francis
