Hello.
I am trying to write and application in Jess using JDBC to connect to a MySQL database.
I am not sure how todefine a java object like Connection and Statement in Jess as in the java statements:
Connection con = null;
Statement stmt = null;
Would it work to write
(defglobal ?*con* = (new

Already in there! See the slightly faulty Toggle Comment item under
the Source menu.
Awesome! Sorry for overlooking this.
...but I couldn't quite find a way to map a key sequence to it. Using

I don't recognize the 'unique' statement. I don't find 'unique' in the

Jess Function List in the 7.0a5 documentation.
The unique conditional element is now unimplemented. It parses in

Probably not possible right now. Should be straightened out eventually.
