[rules-users] UI for Rule Engine

[Gaurav Silakari]

Hi, I need to know whether Guvnor UI is customizable. I have a requirement where there is a need for a customized UI for managing the rules. So for that case, either a new UI has to be created or the Guvnor UI needs to be edited/modified and integrated with the Application. Could anybody please help me on how should I proceed in this case. How can the Guvnor UI be modified and Integrated it with an Application.If a separate UI is been created then how we can connect it with Guvnor to achieve full functionality, any APIs that would be useful or through some web service calls from the Custom UI to Guvnor.Thanks & Regards,Gaurav SilakariMailto: gaurav.silak...@tcs.com  =-=-=Notice: The information contained in this e-mailmessage and/or attachments to it may contain confidential or privileged information.

[rules-users] Calling a method in when part

[Sumeet Karawal]

Hi,

I have a requirement where there is a customized Java class having a method
that returns some value.
like:

getValueBoolean("Some String")

{ //some calculation
   // returns a boolean value
}

The default getters and setters are not being used in the Application. The
value that is being returned by the method needs to be checked in the .drl
file.
There are different Java classes with these kind of methods. Where the
string and integer value is also returned. I have gone through the
documentation for Drools-Expert but have only found the implementation for
the method in the consequence part, i.e., the then part.

This is how I tried:

importing the class

in when
binding the a variable to the Class name suppose $c
eval ($c.getValueBoolean("abc"))
then
System.out.println("the value is true")


It didn't work this way.
I tried by another way like :

creating a function in the .drl itself that calls the method of that class
and returns a value
then calling this drl function in the when part and carrying on.

It would be very helpful if some body could let me know how to do this in
the .drl.


Thanks & Regards,
Sumeet Karawal

[Wolfgang Laun]

If you don't show your code we can't tell you what is wrong with it. So I
think what you may have to do is

when
   $someObj: SomeClass()  # matches each WME of SomeClass
   eval( $someObj.getValueBoolean("abc"))
then

There is not much to be gained by using a DRL function; it would have to be
called like
   eval( someFunction( $someObj, "abc" ) )

Re: [rules-users] Calling a method in when part

[Sumeet Karawal]

Hi,

Below is the drl that I am using and the class that it is referring to:

Drl:

package rules.person

import com.person.Age
Import com.person.Classification

rule "Check_person.option1"

when

$age : com.person.Age()
$classification : com.person.Classification()

eval ($age.getClassification("16"))

then

modify ($classification) {$classification.setResult('"Teenager"; }

end

rule "Check_person.option2"

when

$age : com.person.Age()
$classification : com.person.Classification()

eval ($age.getClassification("40"))

then

modify ($classification) {$classification.setResult('"Adult"; }

end


Application Class :

public class Age
{
public string getClassification(String name) {

return str;
}
}

public class Classification
{
public void setResult(String name) {


}
}



Queries :

   Please let me know if I am using the 'when' part correctly.
   And please check for the use of the object 'classification' in my
   application (as return value to the application)

[rules-users] Collect with same value

[wendy]

Hi,
  I'm trying to write the following rule but am having some trouble.  

  We have a object say Shape and which has attributes size and color.  I
want to get a list of all shapes with the same color that have size > 5. 
How can I make sure the color is the same for all objects in the collect
without having different rules for 'red', 'green'...? 

Thank you,
Wendy

Re: [rules-users] Calling a method in when part

[Sachin Thapa]

There are two things:

1. You want to call this method when a condition is satisfied 
2. You want to check this condition and do something.

If you want to do '1'

when
  <>
then
   boolean val = c.getValueBoolean("string");
end

if you want to do '2'

when
   eval(c.getValueBoolean("string"))
then
   <>
end

I am not sure what you want to do about of these two, hope this helps. If i
have not understand your problem could you please provide more details will
try to post solution.

Sachin

I did some benchmarking yesterday and noticed this too.  I also found that
package load time is much slower when using change sets.

originally my drools-spring file looked like this (snippet):

Hi, 

I'm trying to update the facts before a flowgroup and after a script

Do I need to press in the session to the parameter map and call
session.update(FactHandle handle,   Object object)??

session.fireAllRules();

If you import, you can use just "Age" and "Classification".

This is not correct since the return value of Age.getClassification is not a
boolean.

As you present this code, it doesn't make any sense. The condition is a join
of an Age object and a Classification object and the argument of
getClassification("16") is a literal.

Providing an object to collect results is one reasonable way of doing it.

 Do you activate the ruleflow-group before you insert the Car fact?

try adding /execute to your URL, i.e.

/drools-server/kservice/rest/execute

Re: [rules-users] Insert a fact into drools server from a web application or java application

[kkelleyjr]

I have already tried that... I got HTTP/1.1 204 No Content [Server:
Apache-Coyote/1.1, Date: Wed, 10 Aug 2011 21:21:45 GMT]...


Thank you for the advice... 

I have been thinking that it may have something to do with xstream and jaxb
stuff, but I am very new to both tech's...

Re: [rules-users] Insert a fact into drools server from a web application or java application

[lhorton]

I got the 5.2 drools-server working with xstream.  You can see my code here:

http://drools.46999.n3.nabble.com/rules-users-how-to-invoke-rest-service-on-drools-server-with-serialized-objects-td3179834.html

at the time of that post, i hadn't figured out how to get the return
objects.  this post covers how to do that:

Re: [rules-users] Insert a fact into drools server from a web application or java application

[kkelleyjr]

Thank You I had been looking at your post actually, trying to understand the
difference between the two technologies... I will take a look at the xstream
and will post if I figure out what the issue is with the jaxb...

[rules-users] Drools Queries with relation to the LHS and RHS syntax of the rule

[Dibya]

I have the below two requirement for Drools implementation.

1. To use a java method(with single argument) of my application class in the
'LHS' of the rule .
2. To pass the object set in 'RHS' of the rule back to my application.

Is it possible to implement point 1 and point 2 as below ?

Example :

Application class is defined as :

//Class for getting various types from my application

package application.custom;

public class Project
{
public string getStringValue(String name) {

return ;
}
}

//Class 2 for setting the rule result

package application.customresults;

public class ProjectResults
{
public void setResult(String name) {


}}

===
Drl file like :

package application.rules

#I shall set the object 'projRes'  in my appl using setGlobal
global application.customresults.ProjectResults  projRes ; 

import application.custom.Project;

rule "project-1.option1"

when

$proj : application.custom.Project();

eval ($proj.getStringValue("Drools") .equals ("ABC")) # Logic specific to my
application 

then
#Requirement is to set and make use of the object 'projRes' in my
application

modify (projRes) {projRes.setResult("Drools project");  }
end

rule "project-1.option2"

when

$proj : application.custom.Project();
$projRes : application.customresults.ProjectResults();

eval ($proj.getStringValue("Java") .equals ("DEF")) # Logic specific to my
application 

then
#Requirement is to set and make use of the object 'projRes' in my
application

modify (projRes) {projRes.setResult("Java project");
 }
end


Please let me know if the above way of writing the drl would suffice both
the requirements (or) is there a better way to implement it.

Thanks
Dibya

Re: [rules-users] Insert a fact into drools server from a web application or java application

[kkelleyjr]

I was looking at you code and I was wondering if there is a reason that you
did not use the new httpcomponents for the httpclient?

No reason - I used the old HttpClient because I'm familiar with it.

Re: [rules-users] Insert a fact into drools server from a web application or java application

[kkelleyjr]

Well after modifying some of the code that you gave and setting the drools
server back to using xstream... so basically, the exact code that I posted
but with the xstream marshaller... the code works... so I am very confused
with what the deal is with the jaxb situation

I would think maybe that it has something to do with how to configure the
drools server for jaxb correctly???

[rules-users] best way to write this rule?

[Warner Onstine]

I am new to Drools and I've been trying to figure this out through the
user guide and examples I've been finding, but I'm not sure what the
best way is to write this rule (or set of rules).

What I'm trying to write is a set of rules for determining when
someone has earned (or is starting to earn) a badge. I want to be able
to show their progress on badge completion as well as when they
finally complete said badge.

I'm passing in the following to the rule:
- Player
- Earned Badges (list)
- All possible badges

The first rule only deals with one specific badge. So I have something
like this in my when:
$badge : Badge(name == "Something") //my assumption is that Badge
comes from the list of all possible badges I've just passed in

Then, I decided to split the rule into two. One rule for when they had
not earned it yet:
and I call a function
function earnedBadge(List badges, String name) {
boolean found = false;
for(EarnedBadge badge : badges) {
if(badge.getBadge().getName().equals(name)) {
found = true;
}
}
return found;
}

when:
earnedBadge(badges, $badge (name))

Then I got stuck. If they have completed one or more tasks I would
like to create (or use the badge they've started to earn) to track
their progress. So, If I have 5 possible things they need to do and
they've done three of those I'd like to create a new EarnedBadge for
the one they are earning and give it a percentage of 60%. What would
be the best way to do something like this?

Thanks for helping out the newbie, it's greatly appreciated :).
