| Hello Richard,
WO components can access instance variables just as well as set/get methods, so that's not the issue. (They don't even need to be public.) Perhaps your Main.java has the wrong target, or some other similar scenario. Because although you are seeing them in the source code, they're not ending up in the final, built class.
Regards, Mark
It's the problem. WebObjects don't acces directly the instance variable but the getter and setter methods. Just look at the error message that explains you webobjects try to find the right method .

So add the methods setAPersonn() and getAPerson() (or aPersonn() if you rather like).

Hello,
The instance variable in Main.java aPerson is has access level of pubilc
and the method addPerson is also public.
The class Person is a public also, so think this may not be the problem.
