[jagan reddy]

HI,

I have a small doubt.
I am using kie  workbench and kie server 6.5.0.Final version in tomcat 8

i uploaded a jar file which contains models (Pojo classes).
i uploaded a drools excel file and converted into guided decision tables . i used data object which it refers from jar file. which i uploaded.

build is success
now i want to fire rule by using rest spi (using post man ). or using kie server client api .

url : http://localhost:8080/kie-server/services/rest/server/containers/instances/{container id }
how to be request data to fire rules

Please send me sample request data . please, consider data object are from jar file which i uploaded (i didn't created any data object in kie workbench .)

i need to show demo to the client.
Please, help me

Thanks,
Jagan

Hello Jagan Reddy,

     I'm using Rest Server (Execution Server) with JSON.
     

     -The first step is to create the project and one Data Object to your PoC;

     -Done this, develop some rules to view execution. Example:

             rule "test 1"

             when 

             then System.out.println(´Result of Rule #1');

             end 

      

    - Build&Deploy;

    And done! If no errors founded on your project, your container is created.

    To consume rules, I attached JPG files of the Postman. Of course, adapt to your application.

Best regards and sorry for my poor english.

Are you expecting updated facts after rule execution in REST API response ? Am I correct ?

Hi Abhijit Humbe,
Thanks for reply

yes, i am expecting updated facts after rue execution in REST API response.
one more issues., in guided decision table , one of the action i  have given system print out statement, when all conditions matched it prints statement.

when i fire rules from REST API first time it print statement
         with the same condition    second time it print same statement 3 times.
         with the same condition    third time it print same statement 5 times. it is increasing +2 times. it happens when i fire rules

but in guided decision table conditions matches only one row.
how to fix it.

Thanks,

Jagan

Facts available in working memory are getting reevaluated after sending REST requests to execute rules. In this situation you have two workarounds:

   1. Retract fact from working memory in rules, like as:

         rule retractInitialFact
            when
                  $pojo:MyPojo
             then
                   retract($pojo)

             end

  2. Define maximum number of rules to be executed in  fire-all-rule command:
 {
            "fire-all-rules":{"max":"1","out-identifier":"firedActivations"}
         }

  This approach is not suitable if you have multiple rules to execute.

Thanks,

Jagan

Hi Abhijit Humbe,

Thanks for reply

Please, explain about retract($pojo) 
how to use it.
Thanks,

 Jagan

To remove fact from memory you just need to call pre-defined function 'retract' in the 'then' part of the rule. You just need to pass object reference which you want to remove from memory.
