Mark,

You know what, it was a Drools project. But, it was one created under the old 3.0.6 version. I wonder if this is a migration issue then?

Ron,

Could you clarify - in Eclipse was this project created as a standard Java project or a Drools project? When Drools creates a project it adds in jdt-core from the plugin classpath, which doesn't happen in standard java projects. I've check this myself, and it seems to work fine.

hmm yes that could be a but with JBoss IDE. I'm using the current classloader, suspect i need to use another one.... We want to use the JDT that is already in the Eclipse system.

Kris, do you know what classLoader I need to search for Eclipse?

Mark,

I hope you saw that my earlier problem had to do with the fact that the JBoss Rules IDE did not include the jar file for theclass Java compiler. Once I added it, it started to work. is this a bug in the JBoss Rules IDE as I never had to do this before?

Now onto the other problem, does that mean I have to do something like drools.getWorkingMemory().getQueryResults() then?

Thanks Again!

We have slimmed down what KnowledgeHelper does, so it only does operations involving the current rules context (i.e. the Tuple of matched data), as KH supplies access to the WorkingMemory you can simply call getQueryResults on that.

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.

Ron
