Hi All,


    I am new user of Drools tool. I have done a sample business Rule in Drools and tested. It is working fine in Drools. So I validated the package and imported .drl file into talend studio under Meta data (Embedded Rules).

The code generated for the business rule is as follows:

package modelonsales

import salesmodel.Sales


import java.util.ArrayList
import java.util.HashMap
import java.lang.Integer

global ArrayList list
global HashMap globalMap



rule "SalesBR"
    dialect "mvel"
    when
        exists Sales( sales >= "100" )
    then
        Sales fact0 = new Sales();
        fact0.setName( "Discount" );
        fact0.setSales( -10 );
        insert(fact0 );
end



When I executing the job it is giving errors as follows:


Starting job DroolsJob at 14:14 21/11/2011.
