> In case that you specify interface type for entity bean in ejb-jar.xml that does not correspond with definition in the class of the bean then just Null Pointer exception is shown without any other info what's happening.
> I mean when you define bean through interface as remote and the ejb-jar.xml describes bean interfaces as local
> {code}
> public interface SomeBean extends EJBObject {
> ...
> }
> public interface SomeBeanHome extends EJBHome {
> ...
> }
> {code}
> and the ejb-jar.xml looks like
> {code}
> <ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"
>   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
