Re: [rules-users] Cannot find the declaration of element 'rule-set'.

Main Class as follows package com.sample; import java.io.InputStreamReader; import java.io.Reader; import org.drools.RuleBase; import org.drools.RuleBaseFactory; import org.drools.WorkingMemory; import org.drools.compiler.PackageBuilder; import org.drools.rule.Package; /** * This is a sample file to launch a rule package from a rule source file. */ public class DroolsTest1 { public static final void main(String[] args) { try { //load up the rulebase RuleBase ruleBase = readRule(); WorkingMemory workingMemory = ruleBase.newWorkingMemory(); //go ! Message message = new Message(); message.setOp1(2); message.setOp2(2); workingMemory.assertObject( message ); workingMemory.fireAllRules(); } catch (Throwable t) { t.printStackTrace(); } } /** * Please note that this is the "low level" rule assembly API. */ private static RuleBase readRule() throws Exception { //read in the source Reader source = new InputStreamReader( DroolsTest1.class.getResourceAsStream( "/Sample1.drl" ) ); //optionally read in the DSL (if you are using it). //Reader dsl = new InputStreamReader( DroolsTest.class.getResourceAsStream( "/mylang.dsl" ) ); //Use package builder to build up a rule package. //An alternative lower level class called "DrlParser" can also be used...
