Many thanks for sending reply...
cont with my question.......
i have defined a deffunction in the scriptlib.clp file
this is the code...
(deffunction testFunction (?uid)
"Test Function is called."
(bind ?dbconnection (new DB))
(bind ?val (call ?dbconnection getDBConn ?uid))
(return ?val toString))
where the DB is a Java Class which does the database part........
and the code which calls is
rete.executeCommand("(testFunction userid)");
and i get the userid value from the other program....
but it says unimplemented function testFunction userid.....
so how to pass a String Value .....
Thanks
