Re: [rules-users] Get fact type returning null

2012-01-18 Thread Wolfgang Laun

A class edu.arizona.result is not to be seen (at least for me), and that's why
getFactType() returns null.

Does it work when you create a KnowlegeBase from DRL?

Is Resource changeset != null?

Why do you want to do that? You can compile and integrate them into a
Knowledge Base easily.

There is no such thing.

For your info, for the same rules. It's not always happen, the error some
times coming.
For me the rule is fine (I used guvnor)
Here is the rule

import com.rbtsb.tm.meter.model.CDR;
import org.apache.log4j.Logger;

global Logger log;

rule "ProductTag-FixedSMS"

when
$cdr : CDR(callClassCode == "F1" || callClassCode == "F2" )
then
$cdr.setProductName("fixedsms");
end

Re: [rules-users] ClassCastException when KnowledgeAgent loads declared type

2012-01-18 Thread Davide Sottara

In which order do you load the DRLs? Since resources are loaded one at a
time, the DRL with the declarations should be added to the knowledgebase
first.

Re: [rules-users] unable to load jar file

2012-01-18 Thread Esteban Aliverti

Seems like your model has some Groovy dependencies. If you upload a jar,
all the referenced classes (dependencies) of that jar must to be available
to Guvnor.
What I recommend to do is to create a plain POJO model without any external
library dependency (if possible)

Best Regards,

Hi,

Can anybody tell me how to use groovy classes as fact classes in guvnor.
Because, i tried to upload the jar file of the java classes and it seems to
be working fine.

Thanks,
Kavitha.

[rules-users] Why isn't my rule firing??

2012-01-18 Thread dunnlow

First, my intent:

  1) insert a pojo into a stateful session
  2) based upon that pojo's attributes, create and insert a new fact
(different type)
  3) retract the initial pojo, but keep the newly created fact in memory for
some period of time

After some helpful insight from the forum, I thought I could knock this out.

However, I'm stuck and I've boiled down to what I imagine is a
misunderstanding that I have.  I have the code and rules below.  

With each fact that I insert, I expected 
  1) to see the number of facts grow (the list of facts printed line 16 does
grow with each call).  This works
  2) to see the NotificationEvent added only once to working memory (the
facts printed shows only one NotificationEvent and then a new MyBean for
each one I insert).  So, I think this works also.
  3) BUT, each time I call fireAllRules(), I expect the "foundNE" rule to be
triggered and to see "Found A notification event" printed.  However, this is
only printed once - after my first insert. Also, I see that 0 rules get
fired (line 13) after the first MyBean insert.

SO, if I see a NotificationEvent in the list of facts in line 17, why isn't
my foundNE rule printing out the message each time I insert a new MyBean and
call fireallrules??

FYI, my future plan is to have a rule with low salience that retracts the
MyBeans just inserted and have my foundNE rule retract any
NotificationEvents that are at least 10 mins old.  (so that the
NotificationEvents will grow but not MyBeans) .

Here is my test code (please excuse typos - there are none in my code):

Thanks very much for any insight.
-J

===test.java ===

1  KnowledgeBase kbase = readKnowledgeBaseFromFile();
2  StatefulKnowledegeSession ksession = kbase.newStatefulKnowledgeSession():
3  KnowledgeRuntimeLogger logger =
KnowledgeRuntimeLoggerFactory.newFileLogger(ksession,"testlog");

4  for (int x=0;x<10;x++){
5   myBean mb = new MyBean();
6   mb.setName("me");
7   mb.setHeadline("my_head");
8   mb.setTag("tagline");
9
10  List cmds = new ArrayList();
11  FactHandle fh = (FactHandle) ksession.insert(seb);
12  int rf = ksession.fireAllRules();
13  System.out.println(rf+"rules fired");
14
15  Collection c = ksession.getFactHandles();
16  for (FactHandle f:c) {
17  System.out.println("  now: "+f.toString());
18  }
19
20  Thread.sleep(5000);
21 }

=== test.drl 
import com.me.MyBean
import java.util.Calendar

declare NotificationEvent
name: String
headline: String
tagline: String
dts: Long
end

rule "foundNE"
dialect "mvel"
when
$ne : NotificationEvent()
then
System.out.println("Found a Notification Event");
end

rule "NotTemplate_1"
dialect "mvel"
when
$myb : MyBean(name matches "me", headline matches "my_head")
not ($ne : NotificationEvent(name matches $myb.name,
headline=$myb.headline)
then
NotificationEvent fact0 = new NotificationEvent();
fact0.setName($myb.name);
fact0.setHeadline($myb.headline);
insert(fact0);
System.out.println("Adding a notification event");
end

Re: [rules-users] Why isn't my rule firing??

2012-01-18 Thread dunnlow

Ok, still working on this, but I have more information from 

http://drools.46999.n3.nabble.com/fireAllRules-multiply-times-td1019111.html#a1019469

and

http://drools.46999.n3.nabble.com/How-to-avoid-multiple-calls-to-fireAllRules-if-possible-td50345.html#a50349

apparently fireallrules() doesn't actually fire all rules...the second time. 
this noob is unclear why, but i'm looking into a way to update an fact
handle.  (One challenge I left out of my initial description is that
eventually I'll be connecting to a session on a drools server - so that
further limits my options)

Re: [rules-users] Why isn't my rule firing??

2012-01-18 Thread Greg Barton

This is by design.  Unless you modify an object and inform the inference engine 
of the change, rule conditions will not be re-evaluated.  If you want the rule 
to re-fire you must tell the engine to reconsider the old NotificationEvents 
via update() or modify().  A rule like this would do it every time a new MyBean 
is detected:

rule "TouchAllNotificationEvents"
     dialect "mvel"
     when
          MyBean()
          $ne : NotificationEvent()
     then
          update($ne);
end

Re: [rules-users] ClassCastException when KnowledgeAgent loads declared type

2012-01-18 Thread lhorton

I was able to create a working unit test for the workaround of moving the
declared type out of the rules file and into a different package; but when I
deployed this change on my server, the files loaded ok the first time, but
again I ran into trouble when I would redeploy the base rules file.  This
time I got an error when the knowledge agent tried to load the package:

WARN  2012-01-18 14:15:03,416 [com.abclegal.rules.server.RulesServiceImpl] -
KnowledgeAgent has KnowledgeBuilder errors  object=Unable to resolve
ObjectType 'TransgressionMetaData' : [Rule name='Remedy Transgressions ']

Which looks like another symptom of the same bug.  I will see if I can test
for the bug with 5.4 when I get a chance.

Re: [rules-users] How to combine different drl files

I have about 100 drl files. If I load them in knowledge base, it will be very
slow. So I want to combine them into one big drl file then compile it.

Re: [rules-users] How to combine different drl files

2012-01-18 Thread Wolfgang Laun

You realize that you can compile once and load the serialized
Knowledge Base repeatedly, which results in the fastest possible
startup.

Combining DRL files will be faster but not as fast as using a
serialized KB.

Re: [rules-users] How to combine drl files to one binary file

2012-01-18 Thread Wolfgang Laun

You pass all the DRL files to the Knowledge Builder, one after the other.
Then you obtain the Knowledge Packages. Either you serialize them,
or the Knowledge  Base builot with them.

This is described in the Expert manual.

Re: [rules-users] java.lang.ClassCastException: java.lang.String cannot be cast to com.sample.DroolsTest$Message

2012-01-18 Thread Wolfgang Laun

You cannot cast an object of type java.lang.String (i.e.
$a as it is bound to "add") to Message.

Apparently you have not understood how "from" works.
(Its various forms are described in the "Expert" manual.)
Most frequently, it is used to "pull" one or more objects,
one at a time, from a fact, in order to permit them to
match a pattern although they have not been inserted
in Working Memory.

What I see in this rule doesn't indicate what you might
have intended to do - so I cannot propose an improved
version.
