Is there any way to convert a shadow fact back to a javabean

[Hope Zhu]

Hi,

I have a java application which reads string msg off a queue, converts the string into a javabean and puts it into a Jess rule engine. Because of the high volume (a couple of 100 per min) of the msg I can't offer keeping both shadow facts and beans at the same time in the memory. But later if a rule fired against a fact I need find out which fact fired the rule and convert the fact back to bean and send out the bean to another application. Currently I got stuck on how to convert a fact back to a javabean. Is there a way to do it? This is urgent. My boss is chasing me. Anyone knows please please help.

Thanks in advance.

The shadow fact has a reference to the JavaBean in the OBJECT slot.

Fact theFact = ...
MyBean bean = (MyBean) theFact.getSlotValue("OBJECT").externalAddressValue(null);

Or in Jess

(bind ?myBean (fact-slot-value ?theFact OBJECT))
