It looks like your GUI code is doing something wrong. When you say the 
list is manually supplied for the rpc, I assume you still write this 
list in your own Java code.

The exception you are getting is from a call to getInstance, and in 
addition, apparently the embedded ECLiPSe was destroyed before the 
getInstance call. Since you apparently did not explicitly call these, 
you will need to figure out why this is happening.

Some general question: how are you constructing the goal for rpc? Since 
you are listing the call in Prolog syntax, are you constructing the rpc 
goal as a string? This is not recommended because of the differences in 
syntax between Java and ECLiPSe. It is much better to build your goal 
using the Java data type described in

http://eclipse-clp.org/doc/embedding/embroot044.html

and

http://eclipse-clp.org/doc/embedding/embroot045.html

The second page also tells you how to return results in your rpc. If you 
have a lot of output, it may be better to set up a FromECLiPSeQueue to 
send the output to Java.

Cheers,

Kish
