Re: [rules-users] Need Sample Java Code
You can also write your rules in DRL which is much, much easier (especially
in eclipse) and then convert it to XML, like this:
public static synchronized String convertDrlToXmlRule(String drlRule)
throws DroolsParserException {
DrlParser parser = new DrlParser();
PackageDescr descr = parser.parse(drlRule);
XmlDumper dumper = new XmlDumper();
String xmlDumped = dumper.dump(descr);
// XmlPackageReader xmlReader = new XmlPackageReader();
return xmlDumped;
}
Also, there are some examples in the documentation pages.

I need sample java code that on Drools v5.0.. can anyone share the rule
XML file format along with the sample code
that fires the rules defined in XML? Do i need to save the file with
'.xml' extension or it will be XML data in .drl file?
Please throw some light on this..

Hi,
Thank you very much for all replies.
I've tried also with not ( EPackage(...)), but the result is the same.

continue in my workingMemory.
How I can see the facts of the workingMemory object (and how remove it)?

Hi Antonio,
Documentation states that the complement to not is exists, whereas
not keyword is used to match the absence of a fact (in Working Memory),
and exists keyword is used to test the existence of one or more facts (in
Working memory).
So if you want to test that a fact is not in working memory, then you
should use the
not(MyClass()) pattern.
Hope this helps,
Francois.

[rules-users] Frequently updated facts and truth maintenance
Hello, Recently I've been using Drools (version 5.0.1) to build a small sensor monitoring application and have run into memory consumption issues that seem to be related to logically inserted facts. The way it is set up there are Sensor facts which carry numerically encoded flags that can signal certain properties about that Sensor. My intent was to create rules to detect these flags and insert marker facts in order to abstract how flagging is handled and make it easier for other rules to use this information. Here is an example of the rules I'm using: declare DeltaFlagged sensor : Sensor @key end rule Delta Flagged agenda-group delta flag inference auto-focus true when $sensor:Sensor(eval(isDeltaFlag(flag))) then DeltaFlagged flagged = new DeltaFlagged(); flagged.setSensor($sensor); insertLogical(flagged); end Each Sensor is updated at regular intervals from outside of the rule engine, several hundred times a day. Similar to the examples given here ( http://blog.athico.com/2007/03/writing-rules-for-monitoring-and-time.html). This works very well for short periods of time. However, after many days of operation I can observe a clear memory leak trend. When I inspect a memory dump I see that there are many LogicalDependency objects created and stored by the truth maintenance system (on the order of several million) for each flag fact that has been logically inserted. Only one fact is being inserted per Sensor as expected. I am working under the impression that Drool's truth maintenance should not be recording duplicate dependencies, so I'm wondering what I have done wrong with the equals() and hashcode() methods of my objects to cause Drools to treat each activation of this rule as a new dependency. My Sensor objects use the default hashcode and equals methods. Thank you in advance. Bill ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Does not execute = builder.addPackageFromDrl(new InputStreamReader(this.getClass().getResourceAsStream(ruleFile)))
I am trying to execute a proof of concept. I have some code that runs a
rule. It works in Eclipse, but for some reason doesnt in Netbeans. I want
to get it working within a POJO Service Engine in Glassfish ESB and have is
execute as part of a BPEL orchestration. It does not throw an exception,
but it steps over that one piece of code
public void xmlImpl(String is) throws JAXBException,
FileNotFoundException, Exception {
try {
// unmarshal xml file
// JAXBElementEnrollmentRequest enrollment =
jaxbUnmarshalFromInputStream(is);
EnrollmentRequest enrollment = jaxbUnmarshalFromInputStream(is);
// setup rules engine
RuleRunner rule = new RuleRunner();
String[] rules = {../rules/834rules.drl};
// execute rules on xml file
try {
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilder builder = new PackageBuilder();
for (String ruleFile : rules) {
System.out.println(Loading file: + ruleFile);
builder.addPackageFromDrl(new
InputStreamReader(this.getClass().getResourceAsStream(ruleFile)));
}
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
WorkingMemory workingMemory = ruleBase.newStatefulSession();
Object fact = new Object();
fact.equals(enrollment);
System.out.println(Inserting fact: + fact);
workingMemory.insert(fact);
System.out.println(Firing Rules);
workingMemory.fireAllRules();
} catch (Exception e) {
e.printStackTrace();
}
// marshall changes out to xml file
jaxbMarshalToOutputStream(enrollment, new
FileOutputStream(F:/data/workspaces/enrollmentPOC/data/xmlenrollment.xml));
} catch (JAXBException je) {
je.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
} finally {
try {
} catch (Exception ex) {
java.util.logging.Logger.getLogger(global).log(java.util.logging.Level.SEVERE,
null, ex);
}
return;
}
}
If anyone has any suggestions I would appreciate them. At this point I'm
stuck
Thanks

Are you using Drools 4.x for a particular reason? I suggest you to try with

You are using the old apis,
take a look at the docs about the 5 version to update your code.
If you are working with maven, it should work on eclipse and netbeans.
I'm a netbeans user and I got all my examples running.

[rules-users] Can't make OR Diverge Gateway (Split OR) work
Hi all, I have this simple BPMN2 flow. http://n3.nabble.com/file/n782279/orflow.jpg When I use a XOR Diverge Gateway exclusiveGateway everything works fine. It also works fine for AND Diverge Gateway parallelGateway. But when I use OR Diverge Gateway complexGateway Drools complains that [Split node 'Gateway' [4] has no type.] http://n3.nabble.com/file/n782279/exeption.jpg As far as I can see it does have a type of complexGateway and this is how it looks in the flow definition: complexGateway id=_4 name=Gateway g:x=96 g:y=96 g:width=49 g:height=49 gatewayDirection=diverging / Am I missing something here? Did anyone implemented an OR complexGateway node in a BPMN2 flow successfully? I appreciate any help.
