Gavin
I had the same issue while trying to get values from jess. Ernest told me to use
either a store and fetch method. or to use Defglobals.
I chose to use Defglobal (because it worked)!.
Here is how I have written the code (Ernest correct me if I have any mistakes in the
code).
Here is my rule declaration
(defglobal ?*p* = (new java.util.Vector))
defrule Rule1
;LHS
=>
(call ?*p* addElement (new java.lang.String "Rule1 one run"))
defrule Rule2;LHS
=>
(call ?*p* addElement (new java.lang.String "Rule2 one run"))
Java Code
Rete r = new Rete();
r.executeCommand("(Rule.clp)");
r.executeCommand("(run)");
Vector list = new Vector();
list = (Vector) r.getGlobalContext().getVariable("*p*").externalAddressValue(null);
This will return the vector to java. It worked for me. I tried to use store and fetch
but could not make it to work. Hope this helps.

I've told Gavin in another email to use store and fetch as described
in manual section 4.4.4.
