Vaadin 7 and AppletIntegration

Vaadin 6 / 7 / 8
1

Hi I use Vaadin 7.0.7 and I want to Call an Applet for use a Token.

I did various tests:

  1. Use of AppletIntegration 1.2.9 but when I call applet there’s an Exception “ClassNotFoundException PaintTarget”
  2. Download Legacy 1.2.10 by https://github.com/Haulmont/AppletIntegration/releases but when I cal the page I have the Exception ""Widgetset does not contain implementation for org.vaadin.applet.AppletIntegration. Check its @ClientWidget mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions. Unrendered UIDL:

org.vaadin.applet.AppletIntegration(NO CLIENT IMPLEMENTATION FOUND)"
3) I create a class AppletCustom

public class AppletCustom extends CustomComponent {
    public AppletCustom(String codebase, 
            String archive, 
            String code,
            String width, 
            String height,
            Map<String, String> params) {
        setCompositionRoot(new Label("<div id='appletDiv'></div>", ContentMode.HTML));
        StringBuilder sb = new StringBuilder();
                /* create the applet */
        sb.append("var obj = document.createElement('object');");
        sb.append("obj.setAttribute('type','application/x-java-applet');");
        sb.append("obj.setAttribute('width','" + width + "');");
        sb.append("obj.setAttribute('height','" + height + "');");        
        
        sb.append("var codeParam = document.createElement('param');");
        sb.append("codeParam.setAttribute('name', 'code');");
        sb.append("codeParam.setAttribute('value', '" + code + "');");
        sb.append("obj.appendChild(codeParam);");        
        
        sb.append("var archiveParam = document.createElement('param');");
        sb.append("archiveParam.setAttribute('name', 'archive');");
        sb.append("archiveParam.setAttribute('value','" + archive + "');");
        sb.append("obj.appendChild(archiveParam);");
         
        sb.append("var param = document.createElement('param');");
        sb.append("param.setAttribute('name', 'codebase');");
        sb.append("param.setAttribute('value','" + codebase + "');");
        sb.append("obj.appendChild(param);");
        
        /* add params to the applet if you like */
        if(params != null && !params.isEmpty()){
            Iterator<Entry<String, String>> it = 
                    params.entrySet().iterator();
            while (it.hasNext()) {
                Map.Entry<String, String> pairs = (Map.Entry<String, String>) it.next();
                sb.append("param = document.createElement('param');");
                sb.append("param.setAttribute('name', '" + pairs.getKey() + "');");
                sb.append("param.setAttribute('value','" + pairs.getValue() + "');");
                sb.append("obj.appendChild(param);");
            }
        }        
        sb.append("document.getElementById('appletDiv').appendChild(obj);");
        JavaScript.getCurrent().execute(sb.toString());
    }
}

and i Call it in the page. The applet is seen correctly but i must to return a value using the method

vaadinUpdateVariable("docName", docName + SIGNED_FILE_SUFFIX, true);

How can i resolve my problem?
