JESS: Problem when loading Rule as a String

Hello all,



I receive a Jess rule through the network in XML format and when I try to
load it in the Rete engine, it throws an error. I know the rule itself is
valid.



Am I doing something wrong?



Thanks for the help and tips,

Pierre



Code:

for (String s : rules){

try {

            StringReader read = new StringReader(s);

            Jesp parser = new Jesp(read, Demo.engine.getEngine());

            parser.parse(false);

      } catch (JessException e) {

            e.printStackTrace();

      }

}



Error:

Jess reported an error in routine Jesp.parseExpression.

  Message: Expected a '(', constant, or global variable at token '&'.

  Program text: &  at line 22 in file <unknown>.

Which seems to come from the following line in the XML

            <funcall>

              <name>&gt;</name>
