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! -- View this message in context: http://drools.46999.n3.nabble.com/POJO-accessors-method-in-Drools-facts-t...
