c.setFixedNetNumber(true);

Thanks in advance for your support ...
If you're using Drools 5.2 you should be able to do:
c : CDRRecords( calledNumber str[startsWith] 011 )
If you are on earlier version of Drools you can match with a regular
expression:
c : CDRRecords( calledNumber matches 011.* )

[rules-users] Fire Rule in Stateless Knowledge Session
Hi, I am new in Drools. I am using Drools version 5.1.0 My requirement is kind of request response, where I have to perform some checks for the request and respond the result.

When some request receives I have to identify the rule(s) belongs to that request and then fire the rule(s). I am not able to figure out how to categories the rules request wise in DRL file? Also, how to fire only those rules which belongs to the category. For example, there are three kinds of requests Rq1, Rq2 and Rq3. There are rules in DRL file: R1, R2, R3, R4 and R5. R1, R2 belongs to Rq1, R3 belongs to Rq2 and R4, R5 belongs to Rq3. When some request receives only its belonging rules should be fired. For example, on receiving of Rq2 only R3 should be fired.

Re: [rules-users] Fire Rule in Stateless Knowledge Session
You can have a map of kbases containing the specific rules. When a request arrives, you get the proper kbase from the map and create a ksession from it. Another way could be to use Control Objects in your rules.

Re: [rules-users] Fire Rule in Stateless Knowledge Session
Because of node sharing, it shouldn't be that bad if you use the Request() constraint as the first conditional element of your rules. You must also use always the same order when checking for more than 1 request. For example: rule Rule1 when Request ( type == Rq1 || type == Rq2) ... then end rule Rule2 when Request ( type == Rq1 || type == Rq2) --- Constraints are in the same order ... then end Wolfgang, please correct me if I'm wrong :) Best Regards, Esteban Aliverti - Developer @ http://www.plugtree.com - Blog @ http://ilesteban.wordpress.com On Mon, Aug 8, 2011 at 10:41 AM, snehils sneh...@gmail.com wrote: I thought of doing same but this will become slow when number of rules are more (100 or 200 rules).

Re: [rules-users] RuleAgent - loading rules help ?
Here is some more details:
* Currently our system loads rules from Guvnor installed on a server
(version 5.0.0)
The problem is that there is no way to debug remotely the rules which are
already deployed on Guvnor.
So I was wondering what if I load the rule I need to debug from my local
machine instead maybe then I'll be able to debug it...
* On my local machine I have drools 5.1.0
Here is part of the original code:
public synchronized void loadRulebasesDefinition() {
ruleBaseList = RulesMapper.getRulesMapper().retrieveAllRuleBases();
for (EntryInteger, Rule entry : ruleBaseList.entrySet()) {
Rule currentRuleDefinition = entry.getValue();
Properties ruleBaseProperties =
createRuleBaseProperties(currentRuleDefinition);
RuleAgent agent = RuleAgent.newRuleAgent(ruleBaseProperties);
currentRuleDefinition.setRuleBase(agent.getRuleBase());
}
}
private Properties createRuleBaseProperties(Rule ruleDefinition) {
Properties properties = new Properties();
properties.setProperty(url, ruleDefinition.getRuleBaseURL());
properties.setProperty(poll,
Integer.toString(ruleDefinition.getRuleBasePoll()));
return properties;
}
The info about the rules is retrieved by the Mapper class from a DB and the
result is a map:
MapInteger, Rule ruleBaseList
So I modified the loadRulebasesDefinition() method and I changed the url info
in the DB for some of the rules to start with local: and to point to a
location on my machine:
--
public synchronized void loadRulebasesDefinition() {
ruleBaseList = RulesMapper.getRulesMapper().retrieveAllRuleBases();
for (EntryInteger, Rule entry : ruleBaseList.entrySet()) {
Rule currentRuleDefinition = entry.getValue();
Properties ruleBaseProperties =
createRuleBaseProperties(currentRuleDefinition);
if
(ruleBaseProperties.getProperty(url).startsWith(local:))
{
try {
String path =
ruleBaseProperties.getProperty(url).replaceAll(local:, );
File file = new File(path);
Reader source = new InputStreamReader(new
FileInputStream(file));
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl( source );
org.drools.rule.Package pkg = builder.getPackage();
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage( pkg );
currentRuleDefinition.setRuleBase(ruleBase);
} catch (DroolsParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else
{
RuleAgent agent =
RuleAgent.newRuleAgent(ruleBaseProperties);
currentRuleDefinition.setRuleBase(agent.getRuleBase());
}
}
}
When I start the project it looks like working,
But when I try to debug as Drools application it goes to some point - loads
some rules from URLs etc
- and boom:
Exception in thread main org.drools.RuntimeDroolsException: [Error: not a
statement, or badly formed structure]
[Near : {... Unknown }]
Any idea ?
Thanks Best regards

Subject: Re: [rules-users] RuleAgent - loading rules help ?
Which version of drools are you using?
If you are using a change-set to feed you kagent, then you can use other
protocols rather than http to get your rules from: file://, classpath://

Hello,
Is there a way to tell RuleAgent to load rules not only from remote URL ?
i.e. some rules from URL and some rules from LOCAL path on my computer.
(e.g.: c:\some\folder\rule.drl)
Or if it's not possible exactly that way is there another way to have some
rules loaded from URLs and some rules loaded from local path ?
Best Regards
Ivan
Re: [rules-users] Drools Execution Server memory leak?
Hi, We are having the same problem with a similar setup (drools 5.2.0 Final) using stateless sessions and camel integration, using a KB with ~3000 rules. Session memory is never reclaimed, and after some hours we got an out of memory error. We still dont know the cause, but the profiler shows that these objects are increasing rapidly: org.drools.reteoo.BetaMemory 176.478 +176.163 (+55925 %) 6.893 kB org.drools.core.util.LeftTupleList 175.467 +175.156 (+56320 %) 6.854 kB org.drools.core.util.RightTupleList 172.806 +172.536 (+63902 %) 6.750 kB org.drools.rule.ContextEntry[ ] 164.784 +164.724 (+274540 %)2.659 kB org.drools.core.util.Entry[ ] 160.520 +160.449 (+225985 %)16.561 kB org.drools.core.util.ObjectHashMap 158.309 +158.253 (+282595 %) 6.183 kB org.drools.reteoo.AccumulateNode$AccumulateMemory154.505+154.503 (+7725150 %)4.828 kB org.mvel2.integration.impl.IndexVariableResolver 76.262+76.234 (+272264 %) 1.787 kB We used drools 5.1.1 before with no problems, so we think this leak is upgrade related.

Re: [rules-users] Drools5.2.2 integration with scala2.9.0.1
Thank Mario, Thank a lot for the reply. The solution was really helpful and I am able to run my code. I would also like to know is there any guideline or document to debug these kind of errors, since it doesn't show any problem at compile time or runtime.

[rules-users] Lock-on-active and ruleflow-group
I have three rules: rule First rule salience 20 ruleflow-group rfs_1 lock-on-active true when $c: Car(color == red) then $c.setPrice(1); update($c); end rule Second rule salience 25 ruleflow-group rfs_1 lock-on-active true when $c: Car(size == small) then $c.setPrice(2); update($c); end rule Second step salience 40 ruleflow-group rfs_2 lock-on-active true when $c: Car() then System.out.println($c); end I have class, for example Car, which has three prioperties: color, size, price. I insert into session fact-Car(red, small), next start process, and execute rules. After that, price value is 1. I thought that Second rule should be fired only because it has bigger salience but it is exactly the opposite. Could anyone explain me why first rule was executed/fired and what can I do to fire only Second rule (without invoking First rule).

[rules-users] Off to a very bad start - please help
I downloaded droosljbpm-tools-distribution-5.2.0.Final and installed the plugins in eclipse. I downloaded droolsjbpm-integration-distribution-5.2.0.Final and imported the example project into eclipse (Helios) per instructions in the ReadMeDroolsjbpmintegration.txt file. I used the first mechanism(File/Import) rather than the second (which required m2eclipse plugin). The project is full of errors, and none of the java files would compile. There were no class files generated. I created a Drools project from scratch. I copied the src directory from the example into the new project. The java files now compile and the errors are gone, however something is wrong because it can't find any of the drl files. Also, src/main/resources is not showing in the project tree. I believe that I have followed the directions to the letter (in the first case), and took a wild stab (in the second case) and I am still at the starting point. Won't someone please help me (and shouldn't the ReadMe file be fixed so others don't have this problem) Thanks Ron -- View this message in context: http://drools.46999.n3.nabble.com/Off-to-a-very-bad-start-please-help-tp3237300p3237300.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Off to a very bad start - please help
I wasn't clear. The resource files copied over as well as the Java files. However, the resources (and subdirectories) do not show up at the outer level, as they do on the imported project. http://drools.46999.n3.nabble.com/file/n3237310/DroolsProblem.png -- View this message in context: http://drools.46999.n3.nabble.com/Off-to-a-very-bad-start-please-help-tp3237300p3237310.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Off to a very bad start - please help
You should try with m2Eclipse, it will be easier to handle the dependencies. Maven will take care of the dependencies and the project structure showing you all the resources and adding all of them in the class path. If you don't want to use maven , you should provide all the drools dependencies to the project and set up the right build path in order to see your resources, as in any java project. Cheers.

Re: [rules-users] stopping the rule sequence execution
You can retract the object and it will stop firing rules. Let me know if that doesnt work.
