Exception in loading Skin

I'm using SkinLookAndFeel and want to use the aqua theme pack of SkinLookAndFeel. I've downloaded sklf.jar and aquathemepack.zip. Here is my code:

        Skin skin = SkinLookAndFeel.loadSkin("aquathemepack.zip");
        SkinLookAndFeel.setSkin(skin);
        UIManager.setLookAndFeel(new SkinLookAndFeel());

and the exception is:

java.lang.Exception: Unable to load this skin file:/C:/Workspaces/Demo_Swing/Demo/aquathemepack.zip (by using filename matching),  try an explicit constructor
    at com.l2fprod.gui.plaf.skin.SkinLookAndFeel.loadSkin(SkinLookAndFeel.java:902)
    at com.l2fprod.gui.plaf.skin.SkinLookAndFeel.loadSkin(SkinLookAndFeel.java:883)
    at com.talk.Atalk.&l开发者_开发百科t;init>(Atalk.java:139)
    at com.talk.Atalk.main(Atalk.java:1214)

Why I'm getting this error? How can I solve this?

The SkinLookAndFeel.loadSkin(String) method expects a file name that ends with either "gtkrc" or ".themerc". The source code is here ... is you want to take a look.

Ok I have solved it.

Instead of using loadSkin() I use loadThemePack() and all works fine.
