OK, I got this workinkg now, by adding the jar file core-3.2.3.v_686_R32x.jar from the distribution to my project.

Now though when I run it, I get the following error:

The method getQueryResults(String) is undefined for the type KnowledgeHelper

has getQueryResults been removd in 4.x or renamed?

All,

I am in the process of migrating my 3.0. project to the 4.x series and when I attempt to run my code I get the following exception when I attempt to load my .drl files:

Caused by: org.drools.RuntimeDroolsException : Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialect:java'

Here is my package builder code:

static
    {
        try
        {
            builder = new PackageBuilder();
            builder.addPackageFromDrl( new InputStreamReader( RtvDecisionEngine.class.getResourceAsStream("rtv.drl" ) ) );
            builder.addPackageFromDrl( new InputStreamReader( RtvDecisionEngine.class.getResourceAsStream ("modelDiscrepancyRules.drl" ) ) );
            ruleBase = RuleBaseFactory.newRuleBase();
            ruleBase.addPackage( builder.getPackage() );
        }
        catch(Exception e)
        {
            throw new RuntimeException("Failure loading the Rules", e);
        }
    }

Any thoughts appreciated.
