embedding in ifame

i am trying to embed a vaadin application in my index.html file but an error is comming

Failed to load the widgetset: /testvaadin/VAADIN/widgetsets/com.vaadin.terminal.gwt.DefaultWidgetSet/com.vaadin.terminal.gwt.DefaultWidgetSet.nocache.js?1288345280671

in index.html this is written

my web.xml is

<?xml version="1.0" encoding="UTF-8"?> testvaadin Vaadin production mode productionMode false Testvaadin Application com.vaadin.terminal.gwt.server.ApplicationServlet Vaadin application class to start application com.example.testvaadin.TestvaadinApplication Testvaadin Application /Test/* index.html index.htm index.jsp default.html default.htm default.jsp

why it is not able to load default widget

Add a /VAADIN/* mapping to the servlet and it should work.

yes it was successfull but why what is the reason???
because adding /VAADIN/* only tells the url how to open in browser

i want to tell u something that my problem also got solved before also when i added default widgetset package in \WebContent\VAADIN\widgetsets\com.vaadin.terminal.gwt.DefaultWidgetSet from the vaadin-examples provided by vaadin community
