Hi all, thank you for all the help in the past.
I'm to a point in my project of implementing Guvnor built packages into my java code
that calls drools.
In the past I used the simple solution of building the knowledge agent on a .drl file as
follows:
//Setup the knowledge session for drools
private static KnowledgeBase readKnowledgeBase() throws Exception {
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory
.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("Standard837P.drl"),
ResourceType.DRL);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() > 0) {
for (KnowledgeBuilderError error : errors) {
System.err.println(error);
}
throw new IllegalArgumentException("Could not parse knowledge.");
}
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
return kbase;
}
A little background before the question. My project includes one set of rules that are
standard business logic, we'll call that STANDARD for now and one set of rules that
any one of my 45 customers could have created, we'll call CUSTOMER, on our common
guvnor server. My java code knows which customer is running the app, so determining which
two packages I want to fire is simple. The part that is not as straight forward for me is
how I then I migrate using the guvnor urls in my above code.
I thought it would be as easy as to replace "Standard837P.drl" above with the
STANDARD url and create a second add that would use the CUSTOMER url.
I also want all of my STANDARD rules applied before my CUSTOMER rules are applied. This
got me thinking that I need to have two independent knowledge bases running so that I fire
all in the first and then fire all in the second.
Backing up a bit again, my application looks through an incoming file inserting facts into
the knowledge base for one medical claim line item, fires rules, writes out results to a
database, and then moves on to the next claim line item in the file.
1) What would the syntax need to be to implement the STANDARD and CUSTOMER urls?
2) Would I need to create two independent knowledge bases?
3) DO you see any performance issues in this arrangement?
Thank you!

Hi,
You should be able to use the URL syntax with KnowledgeBuilder as follows:-
final String STANDARD_URL = "
http://your-guvnor-instance-host/org.drools.guvnor.Guvnor/package/standar...
";
final String CUSTOMER_URL="
http://your-guvnor-instance-host/org.drools.guvnor.Guvnor/package/custome...
";
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
UrlResource standardUrlResource =
(UrlResource)ResourceFactory.newUrlResource(STANDARD_URL);
standardUrlResource.setBasicAuthentication("enabled");
standardUrlResource.setUsername("xyz");
standardUrlResource.setPassword("abc");
UrlResource customerUrlResource =
(UrlResource)ResourceFactory.newUrlResource(CUSTOMER_URL);
customerUrlResource.setBasicAuthentication("enabled");
customerUrlResource.setUsername("xyz");
customerUrlResource.setPassword("abc");
kbuilder.add( standardUrlResource, ResourceType.DRL);
kbuilder.add( customerUrlResource, ResourceType.DRL);
assertFalse( kbuilder.hasErrors() );
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
I don't think you'd need to (or want to) create two KnowledgeBases: You
could ensure "standard" rules are applied first by any of Drools' agenda
controls; i.e. salience, agenda-group or ruleflow; plus sharing a single
KnowledgeBase ensures rules in both packages that share patterns are
optimissed in the RETE network.
Use of ChangeSet could make things a little simpler too (rather than the
individual UrlResources).
Cheers,
Mike

Awesome, I was hoping there was a simple solution, but I just didn't see it in all the
documents I've been through. I'm starting out with my proof of concept by just
coding like this and then will look more into ChangeSets as that sounds to be more in
tuned to our application.

In the example below you showed how I could use the .drl, but is there an advantage for me
to directly use the package here? Or say I create a package snapshot and it gives me the
following url
http://vmjboss:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/A_RDR_...
Does using this package decrease the runtime inside of my app because Guvnor has pre-built
the tables?
If so, based on the example below, how would I implement using something like this package
snapshot? Would it be as simple as:
final String STANDARD_URL=
http://vmjboss:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/A_RDR_...;
and then
kbuilder.add( standardUrlResource, ResourceType.PKG);
leaving all other lines the same?
Thank you!

Depending on the amount of rules you have, compilation could be expensive. I
recommend you to use the binary format instead of the drl.
You already figured out the things you need to change in your code, so there
is nothing else to say.
