Eclipse is defaulting to Java 1.5 and you have classes implementing interface methods (which in Java 1.6 can be annotated with @Override, but in Java 1.5 can only be applied to methods overriding a superclass method).

Go to your project/ide preferences by right click your project and choose properties.

and then set the java compiler level to 1.6 and also make sure you select JRE 1.6 to execute your program from eclipse.

Okkay, i hope it can break your prob's ;) happy coding...
