Vaadin inside IFRAME error


I’m trying to integrate the J2EE-application (Oracle BPM 10 Workspace if you interested) with the Vaadin application. I’ve added servlet mapping to my web.xml as described in the Book of Vaadin:

  	Vaadin production mode</description>
  	<servlet-name>BpmVaadin Application</servlet-name>
  		Vaadin application class to start</description>
  	<servlet-name>BpmVaadin Application</servlet-name>
  	<servlet-name>BpmVaadin Application</servlet-name>

The vaadin*.jar and my classes are on their places.

And I’m trying to show this Vaadin-stuff inside of my JSP using IFRAME tag (this is JSF-application, so the page opens inside of another IFRAME, full DOM structure is really terrible):

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
	<iframe src="../vaadinform/" style="width:100%;height:100%;border:0;"></iframe>

And when it’s opening in IE, it’s all good. But in the Firefox (latest) there is a loading wheel and no application inside. The Firebug shows the error:

b is null
Line 3518

What am I doing wrong?
Thanks in advance.


I think Vaadin should run just fine in iframe (and just verified it with a simple test app). Would you provide some more details about your environment? What components do you have in your application? Have you tried the integration with a simple HelloWorld type app?
