You couldn't construct an object with this from Java code, either. Remove that "void" and you should be OK. - Ernest Friedman-Hill Advanced Software Research Phone: (925) 294-2154 Sandia National LabsFAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)

RE: JESS: Problem calling java methods from Jess with Object parameters
Yup, my mistake; the first argument should be '?elem'. Here is the
constructor:
public void MyObject(MyObject parent, String type)
{
setType(type);
this.parent = parent;
}
I'm using version 70b1.
Thanks.

In the constructor call, that ought to be the variable "?elem", not the
symbol "elem", right? If this is just a typo in your email, as opposed
to the rule itself, then can you show me the declaration of the
constructor you're trying to call, and also let me know what version of
Jess you're using?
