Re: [rules-users] How to pass variables to a drools rule file?
It is looking for com.sample.Qos. Try to add the import statement
test.java.Qos somewhere on top of your file.

Hi,there.I have a class in test.java file.It looks like:
class Qos{
boolean S;
boolean W;
Qos(){
S = true;
W = false;
}
public boolean getS(){
return S;
}
public boolean getW(){
return W;
}
}
Now I want to use the Qos class in my rule file like this:
rule rule1
ruleflow-group myRules
salience 4
when
//conditions
$qos:Qos(S==true W==true);
then
System.out.println(rule1);
end
But here is an error.
[Error: could not access field: com.sample.Qos.S]

How can I do?

Re: [rules-users] How to pass variables to a drools rule file?
This is yet another MVEL bug, as it appears to fail to handle package
visibility correctly.
Put Qos into a .java file of its own in any package, precede class by
public and use a proper import in the .drl.
You can omit the import if the package of the Java class and the .drl
is the same.

Re: [rules-users] GC Overhead Limit Exceeded and 1B JoinLeftNode Objects
I wanted to circle back before this thread gets too far off the original topic and folks searching in the future don't get confused. I am still confused between the 'or' and '||' as explained here and in the documentation. I will attempt to review this in more detail. In the meantime, I have simplified my rules per the above comments and am able to run them with about 10M facts in under 3 hours. The system required more than 40GB of RAM. I am chunking the data and running multiple threads. I will look to reduce the overhead where possible as I am certain their are further improvements that can be made. Once I complete out my refactoring and reviews, I'll circle back again. Needless to say, things have moved in a very positive direction. I am not sure what memory expectations I should have so I'll take a complete run in this timeframe without errors as a win. Thank you, Wolgang and Mark. You guys have been fantastic!

Re: [rules-users] Guvnor Configuration file
I take it you hand't performed an export of your rules recently which you could restore? Assuming that you didn't set up a database for storage of your rules, then you should be able to find a directory called repository somewhere on the filesystem of your server. So re-installing Guvnor or the web server is likely to just pick up that location by default.

[rules-users] Guvnor JBoss 7 Authentication
Hi, I'm having some problems getting user authentication working with Guvnor on JBoss AS 7. I have this in beans.xml: security:IdentityImpl s:modifies/ security:authenticatorNamejaasAuthenticator/security:authenticatorName /security:IdentityImpl security:jaas.JaasAuthenticator s:modifies/ s:jaasConfigNameother/s:jaasConfigName /security:jaas.JaasAuthenticator guvnorSecurity:RoleBasedPermissionResolver s:modifies/ guvnorSecurity:enableRoleBasedAuthorizationtrue/guvnorSecurity:enableRoleBasedAuthorization /guvnorSecurity:RoleBasedPermissionResolver And I've created the following files on Guvnors class path: roles.properties: admin=admin users.properties admin=admin This initially gave me a '401 This user has no permissions setup.' error. So I followed this post: http://drools.46999.n3.nabble.com/How-configure-Guvnor-5-4-JAAS-with-jboss-7-0-2-td4020424.html#a4020854 And changed the /SecurityServiceImpl.java file as suggested (not sure if this was the right thing to do or not, but it got rid of the error). However now it gives me incorrect username/password regardless of what I enter. Has anyone had any success with this, or can see where I'm going wrong? I feel like I'm really close but can't work out this last step. As always, thanks for any help anyone can give.

Re: [rules-users] Guvnor Configuration file
That would let you provide a custom location, but it should have saved the repository files in a default location anyway. If I remember right, on a 'nix server, that would be under /repository/ So if you did no customisation, then a new install should pick it up there anyway. Hopefully that enables you to breathe a sigh of relief… :) On 27 Feb 2013, at 16:38, IPatel ishita.pa...@usbank.com wrote: Thank you for your response... Reading your post, i had an ah -ha moment.

[rules-users] How to integrate Declarative Fact created using Guvnor in Java
Hi, Basic questions on the facts that are created in Guvnor using New Declaritive Model I have the facts that are created in Guvnor which i dont have java classes defined. I am refering to the tutorial provided on Chapter 5 The Fact Model and in that it shows how to use the declarative facts from Java. I am having hard time following the steps. So i am going to layout below to see if my understanding is correct: Step 1: // get a reference to a knowledge base with a declared type: KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); Step 2:// get the declared FactType FactType personType = kbase.getFactType( PackageName, FactName ); Step 3:// handle the type as necessary: Not sure what this means Step 4:// create instances: Object bob = personType.newInstance(); Step5: // set attributes values personType.set( bob, name, Bob ); Step 6: // insert fact into a session StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); Step 7:ksession.insert( bob ); Step 8:ksession.fireAllRules(); I am able to understand Step 4 thru Step 8. I guess i am having trouble understanding step 1 and Step 3.

Re: [rules-users] How to integrate Declarative Fact created using Guvnor in Java
The KnowledgeBuilder processes the declared types in a DRL file, creating the bytecode on the fly. When the knowledge package is added to a knowledge base, the newly created class descriptor (the FactType and its related components) become part of the KB and the actual class is (re)loaded by the KB's classloader. Since the dynamic class is not available until runtime, the Type descriptors give you a reflection-like API to manipulate the instances. This said: Step 1: I'd actually get **the** KB which is being used to spawn sessions, to make sure you are using the same classes, as loaded by the same classloader. Step 2: The FactType also holds a reference to the loaded class, you can get it using FactType.getDefinedClass(), if needed Step 3: it's not really a step: it means that the next two steps (4+5) are just an example of what you can do now that you have the Type reference.

If so, how do I know (inside the cloneSolution() method) if the clone is intended for a best-solution or a new working-solution? Why would you need to know that? Would it alter your cloning behavior somehow? It's probably hackable through BestSolutionRecaller, but it will give you a hard time when upgrading to 6.0 if you do hack it there.
