Vaadin 7 and applet - vaadin

Question

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?

you might have have run into one of two Maven GWT plugin bugs: [MGWT-147][1] or [MGWT-148][2] just like [Henri Sara][3] said .
i recommended this blog for you : Vaadin addons and maven and eclipse.
please read this also : Using Vaadin with Maven 2
to help you getting your add-on work . if still n't fixed i refer using [Embedded][6] ui component and avoid the hard coding html tag's.
i wish if i helped you if n't i'm sorry that all i know about Vaadin+applets.
