Hi,
I developed a rule as below:
rule "Rule1"
dialect "mvel"
when
Fields( field1 > "100" )
then
FieldResults fact0 = new FieldResults();
fact0.setField1( "This is Correct!" );
insert(fact0 );
end
After calling fireAllRules(...), the above rule will be fired and
created a fact object in the working memory.
My problem is how to obtain the FieldResults object in the java
program. Please advise.
Thanks
Benson

One thing you can do is to define a global to store that object. Then you
could retrieve it from the outside.

But certainly there is one with heading "global".

ok, do you mean it is like :
global FieldResults frs
rule "Rule1"
dialect "mvel"
when
Fields( field1 > "100" )
then
frs.setField1("This is Correct!")
end
In the java file :
Fields fs = new Fields();
fs.setField1(100);
FieldResults frs = new FieldResults();
sf.insert(fs);
sf.insert(frs);
sf.fireAllRules();
right?

I am using the knowledge session to get the objects created.
knowledgeSession.getObjects():
this will return all objects: the facts that were inserted into the engine before
fireAllRules(), plus the new facts created as result of the rule execution.
Also you can use getQueryResults, or openLiveQuery for the working memory to retrieve
facts from the working memory.

Please excuse my blind bias against globals, but isn't this what Querys are
there for?

A global List object maintains order and can be modified by Java code, none
of which is guaranteed with a query, which incidentally adds some overhead
to Rete.
Not knowing what the ultimate purpose and destination of the FieldResults
facts is, it is difficult to suggest. Perhaps it isn't even necessary to
insert them as facts?
