JESS: Rule calling java external Object problem

[philippe . gibert]

Hello,
My jess version : Jess71p2

I have some  problem with a rule that triggers and call  a java external
Object 
My java class constructor  ( MyMessage ) take as parameter another java
objet ( TicketPS) ..see below 
When i use a String parameter in place of the   My TicketPS class  it
works  nicely ... !!  Any hint ?
Thanks 
Philippe

1)  My Rules.clp: 

(import emb.jess.audiphone.model.*)
(import emb.jess.audiphone.*)
(deftemplate TicketPS       (declare (from-class TicketPS)))
(deftemplate MyMessage (declare (from-class MyMessage)))
(defrule PS-R1
    "Conclure sur Service VoIP OK"
?ticket1 <- (TicketPS  { failure == "306-1" || failure == "306-2"
|| failure == "306-3" })
?ticket2 <- (TicketPS {  failure == "308-1" || failure == "308-2"
|| failure == "308-3" })
=>
(add (new MyMessage ?ticket1 )))

2)  runtime  trace 
 [java] Demo
     [java] Call engine

     [java]     while executing (new MyMessage ?ticket1)
