[rules-users] Drools facts using POJO accessor methods error

[aliosha79]

Hi, 
i have some troubles to undestand how drools processes FACTS. I have a POJO
class resulted from an UnMarshal jaxb processing like this: 

public MyClass { 

protected String className = "Class1"; 

public getClassName(){ 
        return className; 
} 

public setClassName(String className){ 
        this.className = className 
} 

} 


Now i have to compose a drl file with a rule like this: 


when 
        $Class : MyClass() 
        eval ($Class.getClassName() == "Class1") 
then 
        System.out.println("ok!!!"); 
end 


This syntax doesn't rise errors BUT doesn't match the real name... no ok
message are printed. 


when 
        $Class : MyClass (getClassName() == "Class1") 
then 
        System.out.println("ok!!!"); 
end 

This syntax raises me a null pointer exception!!! 


What's the right syntax? 
Can i use the accessor methods building drools facts? 
Thanks a lot!
