Eclipse complain about @Override on interface methods?
Using the @Override annotation on methods that implement those declared by an interface is only valid from Java 6 onward. It’s an error in Java 5.
Make sure that your IDE projects are setup to use a Java 6 JRE, and that the “source compatibility” is set to 1.6 or greater. Open the Window > Preferences dialog, and browse to Java > Compiler. There you can set the “Compiler compliance level” to 1.6.
