Re: Calling Methode using JSNI failed

You should start by carefully reading the JSNI documentation:

http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html
http://googlewebtoolkit.blogspot.com/2008/07/getting-to-really-know-gwt-part-1-jsni.html

A simple JSNI method looks like this (note the specially formatted
braces, which Java sees as a comment block, and therefore ignores):

public static native void alert(String msg) /*-{
$wnd.alert(msg);
}-*/;
