I updated the wiki page with the API code for Drools 4.x:

Let me get this right, i musst use the JANINO-Compiler to avoid problems
with JBoss AS resp. Tomcat?
There is another problem: the
PackageBuilderConfiguration-Method
"setCompiler(PackageBuilderConfiguration.JANINO)" does not exists in Drools
4.0.1

Betreff: Re: [rules-users] JBoss AS 4.0.5 GA + Drools 4.0.1
This is a known conflict between JDT versions used by tomcat and drools.

Hello,
I have many problems to integrate Drools in my existing Application that is
running on JBoss AS 4.0.5 GA.
When I try to load and execute the rule-file I get the following Exception:
java.lang.RuntimeException : java.lang.NoSuchMethodError:
org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclip
se/jdt/core/compiler/CategorizedProblem;
javax.ejb.EJBException : java.lang.RuntimeException :

My Application consists of the following parts:
The rule-file:
#created on: 04.09.2007
package drools.rules
#list any import classes here.
import drools.session.Message;
#declare any global variables here
rule "Hello World"
when
m : Message( status == Message.HELLO, message : message )
then
System.out.println( message );
m.setMessage( "Goodbye cruel world" );
m.setStatus( Message.GOODBYE );
update ( m );
end
rule "GoodBye"
no-loop true
when
m : Message( status == Message.GOODBYE, message : message )
then
System.out.println( message );
m.setMessage( message );
end
a Class to encapsulate the rule-initialisation and rule-execution
(wrapper-Class):
public class RuleEngineWrapper
{
private WorkingMemory workingMemory ;
private boolean debugMode = false;
private DebugAgendaEventListener debugListener ;
public RuleEngineWrapper(WorkingMemory wm) {
this . workingMemory = wm;
debugListener = new DebugAgendaEventListener();
}
/**
* construct a RuleEngineWrapper with only a rule - file - name, no
idea of
* callers' class. Assume the rule file is located
*
* @param rulesFile
*/
public RuleEngineWrapper(String rulesFile) {
this (RuleEngineWrapper. class, rulesFile);
}
/**
* construct a RuleEngineWrapper with only a calling object known
*
* @param caller
* @param rulesFile
*/
public RuleEngineWrapper(Object caller, String rulesFile) {
this (caller.getClass(), rulesFile);
}
/**
* construct a RuleEngineWrapper with Class caller and rule - file -
name known.
* We load the rule - file as classpath resource.
*
* @param caller
* @param rulesFile
*/
public RuleEngineWrapper(Class caller, String rulesFile) {
super ();
try {
final PackageBuilder builder = new PackageBuilder();
System. out .println(caller);
builder.addPackageFromDrl( new InputStreamReader(caller
.getResourceAsStream(rulesFile)));
final RuleBase ruleBase = RuleBaseFactory.newRuleBase ();
ruleBase.addPackage(builder.getPackage());
workingMemory = ruleBase.newStatefulSession();
debugListener = new DebugAgendaEventListener();
} catch (Exception e) {
System. out .println( "cannot read rule file: " +
rulesFile);
}
}
/**
* Allow to add arbitrary objects as facts. Users can add any
objects to
* workingMemory
*
* @param o
* the fact to be added
*/
public void addFact(Object o) {
workingMemory .insert(o);
}
/**
* Execute rules.
*
*/
public void executeRules() {
workingMemory .fireAllRules();
}
