Invoke vaadin widget from the dojo page through an ajax call

Hi Folks,

I have an application where vaadin is embedded in an dojo page. Now i want to invoke or launch an vaadin UI widget from the event of dojo UI component through an ajax call.

I tried by communicating to vaadin ApplicationServlet from the dojo page through an ajax call, but the call does not reach the servlet. However the same works… if i configure an another servlet.

Folks, i would like to know that how dojo page and vaadin will communicate each other.

I would appreciate all the suggestions and solutions.
