Hi all,
I have a strange problem that I hope someone can help. I am trying to
write a bridge between a reasoning tool written in LISP and
Java. Since I dont know of any Lisp to java bindings, I have to use
C. The LISP vendor, Allegro provides mechanisms for making C-calls
from Lisp ( and for C-functions called from Lisp to make Lisp
calls). So does Java.But how can I connect them all, ie. I need
two-way communication between all three.
I was hoping there might be some way to do this as function calls, ie.
the java client calls a C-function which then calls a Lisp function
and output goes the reverse direction. (Is this even reasonable to
hope for ? Since this would mean Lisp and Java would have to share the
C-space ?).
The other way might be to have the C-portion of the server listen on
some port. and have the client send queries there (even though both
are on same machine). But I am not confident about my ability to
program with sockets, plus the problem of converting the data
representation will be left to me.
I would be much grateful if somebody suggest a better way of handling
this problem ? (or perhaps confirm that this is the only way (;-( )
Thanks in advance,
Arun Swaminathan

You should definitely at least check out the Xerox ILU (interlanguage
unification) stuff. If they dont yet have a java binding I bet they
will soon. See
