How to tell if rule is using eval internally
by Jared Davis
How do you tell if a rule is using eval() without access to Eclipse?
The documentation states certain nested accessors will be re-written into eval
statements.

Unable to create Field Extractor
by Hugo Melendez
Hi, I'm using JBoss Rules 4.0.7
and I having this error when executing some rules.
org.drools.RuntimeDroolsException: org.drools.RuntimeDroolsException:
java.lang.IllegalStateException: Error in getting field access
method.Unableto create Field Extractor for 'codigoPlan' of
'[ClassObjectType
class=com.sample.Afiliado]'
The Afiliado class has a getCodigoPlan() public getter to a codigoPlan
field.
The rule is:
rule
when
socio : Afiliado( $codigoPlan: codigoPlan != null );
then
System.out.println( $codigoPlan );
end
I check the manuals and mail lists and everyone has issues with getters.
That's no my case I think.
Any ideas of what's happen ?
Regards,

Guvnor Audit Logging
by Anu＠work
Hi,
Thx to the drools community. I was able to install and run Guvnor 5 CR1 and
Drools Execution Server 5 on Tomcat (Ubuntu) fairly easily. And it works
like magic. I followed the steps below to get my rules running on Guvnor and
execution server after installation
1. created category
2. created package
3. declared model
4. created decision table
5. saved and validated package
6. deployed a snapshot
7. created myrule.properties file with the snapshot URL exported by Guvnor
and put it in the server
8. Ran tests from rails client using JSON.
It all ran perfectly. Now I need to log all input facts and output facts and
the rules fired each time a client posts a request to the execution server.
How do I do that?
Please help.
Thx,
Anu

How to add more knowledge to Stateful session, post start-up
by john.shepherdson＠bt.com
At present I set up a ksession like this:
KnowledgeBase kbase = < call method that loads several rule files and
process flow files via
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()) >
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
Then I set globals, start one of the processes, assert facts, fire rules
etc etc
Later on rules fire that start some or all of the remaining pre-loaded
processes, as required
Is the best way to do it? Instead should I be loading additional rule
and/or process files in to the ksession on the fly, rather than at the
beginning, for performance/scalability reasons? (I couldn't work out how
to do this without overwriting ksession).
Thanks in anticipation,
John Shepherdson

Compiles in 4.07 not in 5.0 Snapshot (3/20)
by Jared Davis
Hi,
This rule (not the best style) compiles fine in 4.07. It gives this error
message using 5.0 Snapshot. I changed some of the text to be generic so I could
post the code.
Rule Compilation error : [Rule name='A.B.inlet.mxb.first.link.20090216.01']
com/zzzzzz/yyy/awl/Rule_A_B_inlet_mxb_first_link_20090216_01_0.java
(11:5517) : The method insert(RuleLink) is undefined for the type
Rule_A_B_inlet_mxb_first_link_20090216_01_0
Here is the rule: (I had to change all the > to . to get gmane to accept the
email as a non top post)
rule "A.B.inlet.mxb.first.link.20090216.01"
agenda-group "A.B"
when
. comp : XComponentRule( path == "~unit~mxb")
then
. Point3d l = new Point3d();
. comp.getBounds().getLower(l);
. if (l.x < 1) {
. insert( new RuleLink("FIRST.INLET" , comp, comp) );
. } else {
. insert( new RuleLink("FIRST.INLET.NOT" , comp, comp) );
. }
.
end
If I change the rule to
rule "A.B.inlet.mxb.first.link.20090216.01"
agenda-group "A.B"
when
. comp : XComponentRule( path == "~unit~mxb")
then
. Point3d l = new Point3d();
. comp.getBounds().getLower(l);
. String name = "FIRST.INLET";
. if (l.x < 1) {
. // nothing
. } else {
. name = "FIRST.INLET.NOT";
. }
. insert( new RuleLink(name , comp, comp) );
.
end
it compiles w/o a problem.

Scenarios
by J Michael Dean
Scenarios are very slick on Guvnor - is there a way to either create
or execute these in Eclipse?
Thanks.
