Hi Avneesh (guessing your name from your email address),

I'm curious what you're actually trying to do. Especially as you refer to "companyDivision" as a rule and as a function in different parts of your email.

If you intend to apply a function to all objects, is there any reason for it to be a guided rule in Guvnor? As Mike mentions, you could create a free-format DRL "technical rule" exactly as you wrote it below. It's perfectly fine to mix the two up. Some rules suit management by a 'business' person within a guided editor and others suit being hard-coded by a developer.

With the example you provide, it looks like you're trying to clone a fact when it is inserted and call a function using the cloned fact as an argument.

If you have a guided rule or decision table which inserts a fact, and you wish to apply a rule/function to the fact after being processed by the first rule, you can do things like set a flag on that fact or insert a new fact type, which the technical free-form DRL rule matches.

As a very trivial example:

when

$company: CompanyBean(!companyDivisionValidated)

then

companyDivision($company);

You would have to consider use of free-format DRL in this scenario.

Subject: how to import function in drl file on guvnor
To: michael.anstis@gmail.com

Hello mantis,
I am very new in drools and guvnor users. I have a problem during making rules. I want to use my predefined functions in rule execution.
Suppose I have a rule "companyDivision" and i want to import it into my rule file like this:

package com.exp.test

import com.abc.bean.CompanyBean
import function
com.abc.util.Validation.companyDivision;

rule "CompanyInfo"
dialect "mvel"
when
CompanyBean( businessType == "ABC" , insuranceProgram == "XYZ" )
then
CompanyBean fact0 = new CompanyBean();
fact0.setBusinessType( "ABC" );
fact0.setInsuranceProgram( "XYZ" );
companyDivision(fact0 );
end

How I can do this.
I am doing following steps to c\generate rules::
1. creating com.exp.test package
2. uploading jar(model) file which included all pojo files of application
3. creating "CompanyInfo" rule

rule file generated by guvnor is like this:::

package com.exp.test

import com.abc.bean.CompanyBean

rule "CompanyInfo"
dialect "mvel"
when
CompanyBean( businessType == "ABC" , insuranceProgram == "XYZ" )
then
CompanyBean fact0 = new CompanyBean();
fact0.setBusinessType( "ABC" );
fact0.setInsuranceProgram( "XYZ" );
insert(fact0 );
end

I have only two options there 1. insert and 2. insert logically.
but on place of insert and insert logically I want to use "companyDivision" function.
Please guys tell me how it is possible.
Thanks
