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.
