I think you may be referring to a comment in the Java-ECLiPSe Interface
documentation:

"...if you are using nondeterminism to generate multiple solutions, you
should collect these on the ECLiPSe side using a meta-level built-in
predicate such as findall/3 and then return the result to Java"

This means that you can't use non-determinism in the part of the code which
interfaces directly with Java. However, you *can* use it internally in the
Eclipse program. So unless you wanted to do return all the solutions to Java
before processing them in some way, you can process the solutions in ECLiPSe
and then return the result to Java. If you need all solutions passed to
Java, you could use a FromEclipseQueue to send each solution to Java as soon
as it is generated, and have Java record it somewhere. 

Hope this helps.

Hello,

I don't have choice : I use ECLiPSe with Java...(sorry for the missing 
informations in previous mails)
I read in the documentation that it's the only way to obtain the
results.Also, I call the library fd (lib(fd)).
I have for my test 2 predicates like in the previous mail (with  constraints

a little different in each other) and I use the results
to compute intersection, or difference, ...
I don't see others ways to do that.
I know that I have to restrain the research space but the constraints are 
imposed to me and domains are very large (some domains are comprised between

0 and 5000 and the only constraint is X>2700)

Olivier
PS : I discover ECLiPSe. Thanks for your patience.
