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.

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?

Using the string you have there and reflection the system tries to load
the JavaDialect, as long as its in your classpath it should work. The
code to do this is straight forward and is in PackageBuilderConfiguration:
public DialectRegistry buildDialectRegistry(PackageBuilder
packageBuilder) {
DialectRegistry registry = new DialectRegistry();
ClassLoader classLoader =
Thread.currentThread().getContextClassLoader();
for ( Iterator it = this.dialects.entrySet().iterator();
it.hasNext(); ) {
Entry entry = (Entry) it.next();
String str = (String) entry.getKey();
String dialectName = str.substring( str.lastIndexOf( "." ) +
1 );
String dialectClass = (String) entry.getValue();
try {
Class cls = classLoader.loadClass( dialectClass );
Constructor cons = cls.getConstructor( new
Class[]{PackageBuilder.class} );
registry.addDialect( dialectName,
(Dialect) cons.newInstance( new
Object[]{packageBuilder} ) );
} catch ( Exception e ) {
throw new RuntimeDroolsException( "Unable to load
dialect '" + dialectClass + ":" + dialectName + "'" );
}
}
return registry;
}
I've know idea why this is failing for you, let me know what you find.

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.

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!

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?

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.

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?

On the other issue, what is the correct way to get a hold of current working

Mark,
On the other issue, what is the correct way to get a hold of current

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

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.
