Capture cross domain content in iFrame | JSF

I use iFrame in my application in which I open other applications from different domains. I want to capture content of these applications either as raw text data or as an image (then I will apply OCR on this image).

I use JSF Framework.

I searched for this issue, but I found that I can't get iFrame content if these contents are from different domains. (Security Issue)

Could you please help me regards this? Please advice.

Thanks in advance.

Mahmoud Khodier.

Welcome to the JavaRanch, Mahmoud.

This is correct. It's a major security issue when one webserver can reach out through a client and muck around with another webserver. In fact, a lot of the trouble we've been having with the CodeRanch JForum software lately stems from our work on plugging loopholes in that restriction that can come from a compromised client program.

You should be able to copy/paste and drag/drop manually between the IFrames, I believe, but automated data transfer and control is haram.

JSF doesn't work all that well with frames in any event, whether original-style or IFrame.

An IDE is no substitute for an Intelligent Developer.
It is sorta covered in the JavaRanch Style Guide.
