Jonah installation error

I installed Jonah R2 kit. The installation was pretty smooth. I simply
followed the instructions.

The only problem I ran into was the following. The build procedure could not
find jni_md.h. I copied the file from JDK include to my Jonah build tree and
every thing worked fine. Is this due to a problem in my environment
(incorrect envir variables, path, etc.) or is this due to a problem in the
build procedures?

Thanks a lot. Great job folks!
