Best way to investigate this is to expand your DSL to the DRL to check how the expansion is working.

        DrlParser parser = new DrlParser();
        String expanded = parser.getExpandedDRL( drlSourceString, dslReader );
       
   Check what is wrong in the expanded DRL. I see your map has an error:

$stud : Student(name == "{studName}")

   The comparison must be made with '==' as above instead of '=' as in your template. But I don't know if that is the only problem.

Hi All,

    I used the following code in the dsl file.

DSL:

    [when] Check whether the name is present as "{studName}" = $stud :
Student(name = "{studName}");
    [then] Set the Error Code {errorCode} = String string = $stud.getName();
Error(errorCode, string);

DRL:

    package com.policy;
    expander StudendProgram.dsl;
    import java.util.Iterator;
    import com.class.Student;
    import com.class.Error;

   rule "StudendProgram_1"

        when
                Check whether the name is present as "Stephen"
        then
                Set the Error Code 88
    end


When I try to run this program I got the following error.

   Caused by: org.drools.rule.InvalidRulePackage: Rule Compilation error
File com/policy/Rule_SpeCodeSpeValProdPlan12_0.java, Line 12, Column 176:
Unexpected token "." in primary

When I remove the Line "$stud.getName();" in the then part and set the error
code alone its working fine. The "." inbetween $stud and getName() may be
the problem. But I don't know the solution for this.

Any suggessions on this.

Thanks,
McShiv....
