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....
