jme2.0 error


Hello...
I performed the eclipse setup for jme2.0
http://www.jmonkeyengine.com/wiki/doku.php?id=jme2-creating_your_first_app_with_simplegame
An error occured while making the sample of leson1 on the link above
Texture texture = TextureManager.loadTexture(
        Lesson1.class.getClassLoader().getResource(
        "jmetest/data/images/Monkey.jpg"),
                Texture.MinificationFilter.BilinearNearestMipMap,
                Texture.MagnificationFilter.Bilinear);
I dont have the types of Texture.MinificationFilter.BilinearNearestMipMap and Texture.MagnificationFilter.I don't have bilienar types but there are those types in the samples. May I have setup it in a wrong way? Or is the problem something else?
