java. Lang. illegalaccessexception: is it related to the public / private attribute of the class?

The following error occurred in my java code:

java.lang.illegalaccessexception: Class org.apache.commons.digester.ObjectCreateRule can not access a member of class Response with modifiers ""

Maybe it's because the course response is not a public course? If so, how can I make it accessible and save the class response in the same file as the main class?

thank you

Update, code: http://www.smipple.net/snippet/aneuryzma/on:%20is%20related%20to%20public%20/%20private%20attribute%20for%20classes%20%3F

Solution

As far as I remember, your class response should follow the bean Convention: it should be public, there should be a public default constructor, and there should be setters and getters for all fields you reference from XML
