Re: JESS: Fetching Multislot List

[Karen Fox]

What's coming back is a list where every item in the list is an instance 
of a Protege class.  How do I interrogate the contents of the instance 
from Java?

I am able to store variables from Java into Jess and use them in a 
batch file.  I then want to retrieve the multislot list that has been 
put together within this batch file and view the list.  I've tried 
several different things, none of which has worked.

Here is where I store the list in the clp file:

(defrule complete-search
   (goal-is-to (action "complete") (argument1 $?iplList))
=>
   (store IPLLIST $?iplList)
   (printout t "We are finished!! " crlf)
   (printout t "Final list is:  " crlf)
   (stepIPLList $?iplList)
)
Here is the latest attempt to retrieve the list from Java:

//fetch stored result
           System.out.println("Results are " + 
r.fetch("IPLLIST").listValue(null));

which gives me this error:

Results are 
<External-Address:edu.stanford.smi.protege.model.DefaultSimpleInstan
ce> 
<External-Address:edu.stanford.smi.protege.model.DefaultSimpleInstance>

I've tried using externalAddressValue(null) and that didn't work 
either. I tried using the Enumeration example from the manual and that 
didn't work.  I'm sure I'm doing something very stupid as a newbie, 
but I'm not seeing it.  I'd appreciate any suggestions.

Thank you.
