JESS: Print Jess rule in detail using Java code

In my Java code, I have:

            Rete engine = new Rete();

engine.batch("myrule.clp");      


Now how do I print out, by Java code, LHS and RHS of the rules that are in
"myrule.clp"? 

I had tried to use this to print the LHS:

for (Iterator iterator = engine.listDefrules(); iterator.hasNext();) {

            Defrule rule = (Defrule) iterator.next();

            for (Iterator iterator2 = rule.getNodes(); iterator2.hasNext();)
{

                  Node node = (Node) iterator2.next();

                  if (node.getNodeType() == 1) {

                        System.out.println("--" + node);

                  }

            }

            System.out.println("Action: " + rule.getAction(0));

      }

But the output looks really annoying. 

Can anyone help me?
