Access to external Embedded content


i’m browse in Embedded component my servlet:

ExternalResource source = new ExternalResource("");

This is IBM Lotus webform.
All OK, but in HTTP header of this servlet are important data (Form ID) that is important for me to know!
These data are also duplicated within the HTML text of my servlet.

Is it possible to get access to IFrame (embedded) content through Vaadin application?

I think it should be possible if the iframe is open to the same domain (and port). There’s no built-in support for that, but you can do it in a custom GWT widget or with JavaScript.

It’s usually not possible to different domains, which is a security feature in browsers. Otherwise some friendly website could offer you a handy little embedded view to your Internet bank account. Afterwards, you might notice some extra transfers that you dont remember making…
