Re: [rules-users] Concurrency problem in PackageClassLoader

2011-09-28 Thread S_Kumar_P

I also was getting this error. I brought out package building logic to execute 
once, and KnowledgeSession related logic to repeat the required number of times.

Seems there required some delay in preparing rules related classes into one 
package during iteration and loading the same. Above step was working fine for 
me.

Pseudo code:

  KnowledgeBuilder kbuilder = 
KnowledgeBuilderFactory.newKnowledgeBuilder();

  // this will parse and compile in one step

  // get the compiled packages (which are serializable)
  Collection pkgs = null;

  // add the packages to a knowledgebase (deploy the knowledge packages).
  KnowledgeBase kbase = null;

  StatefulKnowledgeSession ksession = null;
  // constructor to be called once
public RuleEngine (byte[] rules) {

kbuilder.add(ResourceFactory.newByteArrayResource(rules),ResourceType.DRL);
//  Check the builder for errors
if (kbuilder.hasErrors()) {
  System.out.println(kbuilder.getErrors().toString());
  throw new RuntimeException("Unable to compile drl.");
}
pkgs = kbuilder.getKnowledgePackages();

// add the packages to a knowledgebase (deploy the knowledge 
packages).
kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(pkgs);
  }

// this method will be called required number of times
  public void fire(Object obj) {

ksession = kbase.newStatefulKnowledgeSession();
ksession.addEventListener(new DebugAgendaEventListener());
ksession.addEventListener(new DebugWorkingMemoryEventListener());

// setup the audit logging
//KnowledgeRuntimeLogger logger = 
KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "log/drools.log");

ksession.insert(obj);

ksession.fireAllRules();

//logger.close();

ksession.dispose();
  }


Check this out.

But you may start by using the existing report. If you go under Guvnor 
and see the package page, in the URL listing part, you will find a 
"documentation" link, which generates a PDF report with all your

Re: [rules-users] Can you remove logging information from BatchExecutionCommand?

2011-09-28 Thread dunnlow

Figured it out.  In case anyone else sees this, the issue was that the bean
that I was sending to the Drools server had a "logger" property, which
XStream was trying to serialize.  I didn't want to do a
myBean.setLogger(null) because I wanted to actually do some logging in the
bean.  So, the solution was to ask XStream to omit that logger property when
it created the XML.

I tried adding the annotation @XStreamOmit before the logger property in my
bean, but that didn't work.  I had to do this:

8<...
  BatchExecutionCommand command =
CommandFactory.newBatchExecution(cmds,"kession1");
  XStream xs = BatchExecutionHelper.newXStreamMarshaller();
  *xs.omitField(com.company.MyBean.class,"logger");*
  String xml = xs.toXML(command);
8<..

[rules-users] Can you remove logging information from BatchExecutionCommand?

2011-09-28 Thread dunnlow

I am sending a batchexecution command to a drools server:

8<...
  MyBean mb = new MyBean();
  List cmds = new ArrayList();
  InsertObjectCommand insertCmd = (InsertObjectCommand)
CommandFactory.newInsert(mb);
  insertCmd.setOutIdentifier("inserter");
  insertCmd.setEntryPoint("Default");
  cmds.add(insertCmd);
  FireAllRulesCommand fireAllRulesCommand = new FireAllRulesCommand();
  cmds.add(fireAllRulesCommand);

  BatchExecutionCommand command =
CommandFactory.newBatchExecution(cmds,"ksession1");

  String xml BatchExecutionHelper.newXstreammarshaller().toXML(command);  
8<...

The xml created by that last line contains A LOT of logging information and
includes characters that seem to be invalid.  (drools server throws a
"ConvertsionException, Invalid character reference: null character not
allowed in XML content" when it reads the XML)

Is there a way to tell the BatchExecutionHelper NOT not to include that
logger information?

ps.  I tried things like turning off the root logger programmatically before
calling.  Also, I tried setting a global parameter "logger" to a null object
(I saw that somewhere) but that didn't work either.
commands.add(CommandFactory.newSetGlobal("logger", null));

Thanks for any insight.

I think you can create functions in Guvnor and use that.

For a complete picture, get the Expert manual of 5.1.1. Most constraint have
to be written as

   field == (one + 2) // parens are required

Can you please explain what you mean by "deviate from the constraint syntax

Re: [rules-users] Not able to call parameterizied Java method in LHS

2011-09-28 Thread Tinku

rhs part worked ok now..

I am facing one more issue with calling a method in lhs of the rule ..

When I call a method as mentioned below ('getValue' is the method in class
'customObject' and 'numberofObjects' is method in class 'AnotherObject') ;
the drl file has problems in saving in eclipse.
The error says like 'Multiple Markers at this line'

***
rule A

when
$B : customObject() 
$C : AnotherObject()
eval($C.numberofObjects($B.getValue("Database")) > 10) 
then

end

Re: [rules-users] Getting Exception while running rules continuously on the Event Streams from Mule Component.

2011-09-28 Thread Hari Kishan

Done the same way using accumulate ... but still the exception is thrown.

May be the Frequency of Exception occurring is reduced. 

But this time it is occurring from the Accumulate Node.

Some times the Rules Execution is continuing even after the Exception. 
Some times the Exception keeps on repeating continuously for event (may be
here the Context/Working memory is lost).

I am really getting frustrated with this. 
Need to find the permanent solution for this.

Want to know If this is a bug in Drools 5.0.2 . and got fixed in the later
version. If yes please mention the version number . I will check if i can
succeed by replacing the Drools Version in the Mule ESB.

2011-09-28 Thread Hari Kishan

The below code which you wrote is very appropriate but where should we
mention on which collection we are traversing the conditions on .


Like in collect 

$alarms : ArrayList(size>0) from collect ( Alarm( .. ) from 
  
av.getAlarms() )

Here is an example:

 

$av: List() from accumulate ( $a: Alarm( ...select "interesting" alarms...

init( List alarms = new ArrayList(); )

action( alarms.add($a); )

reverse( alarms.remove($a); )

To select "interesting" alarms, separate the constraints for fields

Re: [rules-users] DROOLS PLANNER - getting started

2011-09-28 Thread Geoffrey De Smet


Either create a new eclipse project from the directory examples/sources 
(from the download zip) and add the jars from the binaries directory 
(not the examples/binaries directory!)
Or install the m2eclipse plugin and open the examples/sources/pom.xml 
(from the download zip).

Afterwards, just run DroolsPlannerExamplesApp.

@wolfgang

Yesterday you told me to use accumulate instead of collect.
But i could not find the right way to use accumulate here.
Please see below my rules when condition [ collect function(Bold & Italic) ]
and please tell me how can i use accumulate there. If possible change the
conditional element to accumulate with appropriate changes.

when
// "Sensor Data Idem Stream" is where Mule sends the Sensordata facts
// for each Alarm / Sensordata combination that is identified via the
vehicle id
$sd : SensorDataIdem ($vid : vehicleId) from entry-point "Sensor Data
Idem Stream"

// Set a references for later on the initial facts 
$av : AlarmVehicle(vehicleId == $vid)   

//The Condition to be added to get the active Alarms from the List of
Alarms
eval($av!=null && $av.getAlarms()!=null && $av.getAlarms().size()>0)

/*$alarms : ArrayList(size>0) from collect ( 
Alarm(  
(
(activation == 
AlarmConstants.ALWAYS_ACTIVE) 
||  (activation == 
AlarmConstants.ACTIVE_ONLY_ONTOUR && $sd.onTour
== true)
||  (activation == 
AlarmConstants.ACTIVE_ONLY_NOT_ONTOUR &&
$sd.onTour == false)
||  (activation ==
