It does not seem related to the reference being a superclass.
I added a second servlet which uses a reference to
RectangularWithDiagonalsPuzzle
directly.
@WebServlet(urlPatterns="/DiagonalSlitherlink/GetDiagonalSlitherlink")
public class GetDiagonalSlitherlinkImpl extends RemoteServiceServlet
implements GetDiagonalSlitherlink {
private static final long serialVersionUID = 1L;
public RectangularWithDiagonalsPuzzle getPuzzle(String category) {
try {
RectangularWithDiagonalsPuzzle puzzle =
(RectangularWithDiagonalsPuzzle)FileUtil.deSerialize(PathUtil.PUZZLES_DIR+
"/DiagonalSlitherlink/Challenging/DiagonalSlitherlink-00001-3.ser");
LogManager.getLogger(getClass()).warn("In DiagonalSlitherlinkImpl,
Loaded puzzle "+puzzle);
return puzzle;
} catch( Exception e ) {
LogManager.getLogger(getClass()).error(e);
return null;
}
}
}
And I see this in the server log:
WARN: In DiagonalSlitherlinkImpl, Loaded puzzle
com._3dmathpuzzles.slitherlink.RectangularWithDiagonalsPuzzle@76c929a9
Thank you,
Neil
