What's wrong with my applet?

[Antonio Lazaro Carvalho]

I'd like to use prefuse (framework to visualization) then I extend a Treeview component and put in my code this:

package tree.applet;
 
import prefuse.util.ui.JPrefuseApplet;
import tree.componentes.TreeView;
 
@SuppressWarnings("serial")
public class TreeViewApplet extends JPrefuseApplet {
 
public void init() {
 
this.setContentPane(TreeView.demo("C:\\Desenvolvimento\\xml\\Informatica.xml", "name"));
 
}
}

but in my jsp file I tried this

<object
            classid = "clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
            codebase = "http://java.sun.com/update/1.6.0/jinstall-6-windows-i586.cab#Version=6,0,0,105"
            WIDTH = "480" HEIGHT = "140" ALIGN = "middle" >
            <PARAM NAME = CODE VALUE = "DrawTest.class" >
            <PARAM NAME = ARCHIVE VALUE = "treebolic.jar" >
            <PARAM NAME = MAYSCRIPT VALUE = true >
            <param name = "type" value = "application/x-java-applet;version=1.6">
            <param name = "scriptable" value = "false">

                    type = "application/x-java-applet;version=1.6" \
                    CODE = "DrawTest.class" \
                    ARCHIVE = ""treebolic.jar"" \
                    WIDTH = "480" \
                    HEIGHT = "140" \
                    ALIGN = "middle" \
                    MAYSCRIPT = true
                    scriptable = false
                    pluginspage = "http://java.sun.com/products/plugin/index.html#download">
                    <noembed>
                        
                    </noembed>
                </embed>
            </comment>
        </object>

and it doesn't work.
I put prefuse.jar,plugin.jar and another class (my components and applets)
in a treebolic jar file, but doesn't work.
I'm using struts 2...
