Re: [rules-users] Hot Deployment
Brian,
I'm guessing that you mean the RuleAgent Class. The Javadoc on this
class gives more info.
Code sample (assuming that you have the BRMS setup as per the doc).
You'll need to change to whatever settings are appropriate for your BRMS.
Properties prop = new Properties();
prop.setProperty("url",uri);
prop.setProperty("newInstance", "true");
prop.setProperty("localCacheDir", ".");
prop.setProperty("poll", "300"); // poll every 300 seconds
for hot deployment.
//Get a new RuleBase using these properties
RuleAgent agent = RuleAgent.newRuleAgent(prop);
RuleBase rb = agent.getRuleBase();
Then use the RuleBase as normal

Hi, Can I keep two instances of the same class in working memory? I guess 'Yes'. If yes then how do I access each instance separately in DSL?

[rules-users] RCP and Drools
I have continued to try to isolate the problem that I have previously
described, where my RCP application that calls Drools runs properly,
but am unable to Unit test. Can reproduce the problem simply and am
hoping someone can lend some insight.
I started by creating a simple Drools project that had a JUnit 4 test
in it; this runs. It contains two java files and a DRL file. (Shown
at very bottom of this post)
I then created a Hello World RCP application from the Eclipse
templates. I copied the Drools project files (2 Java files and 1 DRL
file) into the same package as my RCP stuff. When I run the test, I
get the following error, which is exactly the same error I have been
getting with my much more complicated project:
java.lang.NullPointerException

I then removed all the source files relating to the RCP itself, and
the error persists. If I now remove the plugin dependencies from this
project from the build path, the problem goes away and the tests run.
If I add the plugin dependencies back into the project, the error
resumes. Finally, if I make my ORIGINAL Drools project depend on this
second one with the plugin dependencies, the test fails there too. If
I remove the plugin dependencies, the tests run.
The plugin dependencies are:

[rules-users] Problem when compiling rules in Jetty + Eclipse
Hi Everyone!
We've been using the engine for quite a while in the project (a web
app) and now we're switching from Tomcat to Jetty in our local dev
environments. This change triggered a strange error when it compiles
the rules (both with the eclipse and janino dialects).
I'm using eclipse 3.3.2, Jetty 7.1.7 and the error happened in Drools
4.0.4 to 4.0.6 (may be in other versions too).
The exception I'm getting with the janino dialect (which is more
verbose) is attached and the rule (here's a small snippet)
org.slf4j.Loggerorg.slf4j.LoggerFactoryorg.slf4j.Loggerorg.slf4j.LoggerFactoryorg.slf4j.Loggerorg.slf4j.LoggerFactoryorg.slf4j.Loggerorg.slf4j.LoggerFactoryorg.slf4j.Loggerorg.slf4j.LoggerFactoryorg.slf4j.Loggerorg.slf4j.LoggerFactoryorg.slf4j.Loggerorg.slf4j.LoggerFactoryRule

And I'm executing the following rule:
package com.elixir
#list any import classes here.
import com.elixir.model.*;
import java.util.HashSet;
import java.util.Date;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
rule "insertion of versions"
ruleflow-group "fact-insertion"
when
$a: Artifact(versions != null)
$v: ArtifactVersion() from $a.getVersions()
then
insert ($v);
LoggerFactory.getLogger("factinsertion.drl").info("Entered:
insertion of versions");
end
And the PackageBuilder get's instantiated like this:
PackageBuilderConfiguration
pkgBuilderCfg = new PackageBuilderConfiguration();
JavaDialectConfiguration javaConf = (JavaDialectConfiguration)
pkgBuilderCfg.getDialectConfiguration( "java" );
javaConf.setCompiler( JavaDialectConfiguration.JANINO );
PackageBuilder builder = new PackageBuilder(pkgBuilderCfg);
I'm quite sure that this is a mistake in how I'm running this, but I
can't find the solution :S.
Oh, and just in case, we're running the application without any
problems in jetty but not from inside eclipse.
Thanks in advance,
Augusto

[rules-users] Rules File Design Consideration
Hi, Any help to the problem below is much appreciated : ) Here is the problem: I have a set of rules. Intially these rules are evaluated individually. However, now there is a need to fire these rules in groups which is similar to a logic gate AND or OR. And, the results of this "groups of rules" are collected and returned to the user/ For example: There are 4 rules: Rule 1 Rule 2 Rule 3 Rule 4 Now, need to evaluate (Rule 1 AND Rule 2 AND Rule 3) OR Rule 4 And I need to know what are the results of Rule 1 to Rule 4 individually. What is the best way to implement a AND or OR using Drools? Best regards Chong Minsk ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Unable to fire Rules
Hi,
your rules represent the following Java Code (the system.out are just
to see the result of matches)
public static void main(String[] args)
{
// You're rule
System.out.println("ABC-834".matches("ABC-834-test-100.edi"));
//false
System.out.println("XYZ-834".matches("ABC-834-test-100.edi"));
// false
System.out.println("834".matches("ABC-834-test-100.edi")); //
false
so it could never work
but maybe this is what you want to have
// m.fileName matches .*+fileMask+.*
System.out.println("ABC-834-test-100.edi".matches(".*ABC-834.*")); //true
System.out.println("ABC-834-test-100.edi".matches(".*XYZ-834.*"));
//false, if this should also be true because fo the 834 you have to
use regex grouping with an optional group before the -
System.out.println("ABC-834-test-100.edi".matches(".*834.*"));
//true
}
Cheers

[rules-users] Unable to fire Rules
Hi,
I am inserting message(fileName, fromQ,toQ,transType) to WorkingMemory.
fileName as "ABC-834-test-100.edi"
I am inserting 3 instances of TrasactionVO's to workingmemory as follows:
TransactionVO transVO = new TransactionVO("ABC-834", "ABC.834.EDI",
"ABC.834.XML", "834");
TransactionVO transVO1 = new TransactionVO("XYZ-834", "XYZ.834.EDI",

TransactionVO transVO2 = new TransactionVO("834", "INBOUND.834.EDI",
"INBOUND.834.XML", "834");
In drl, which ever object of TransactionVO matches the fileName of Message,
then update Message's rest of the details with TransactionVO. But the rules
are not getting fired.
Follewed is the testCase and .drl file along with FactObjects.
