This URL has code sketched out for using Java to send C data structures
to legacy C transaction based systems.  I wrote a program based on this
and it works quite well.

        There is a design point left out of this, however.  It shows how
to send and receive fixed length character fields, 32 bit integer
fields, 64  bit integer fields, etc.  The C data type missing is
unsigned int and/or unsigned long.

        Would anybody have an idea how to send and receive a 32 bit
integer field in which the top bit does not indicate a negative number?
