Taking website screenshots with Flash (or Java), client-side

Is there a way, or is it even possible to take a screenshot of a website with Flash (or Java)? If i开发者_开发问答t is, could someone please provide some basic information on how to achieve this?

The reason why I need it to be Flash or Java (or even Canvas), is because the screenshot needs to be done on the client-side.

I did some research with no definitive answer to my question.

From Flash you can not take a screenshot beyond the actual view of the flash rendering area - for security reasons. Just ask the user to press PrintScreen.

I did something like this before. Although my solution was to just have javascript send back the actual html rendered on the client-side. I had a servlet that accepts the html code, then the servlet calls an executable (I can't remember what it was, but it was a freeware but has a watermark, it accepts an html in its command-line argument) that produces an image from the html, which the servlet saves to a directory.

Although the business user's requirement also included making sure that the code is not used for spying or snooping on the client side... But they agreed with the outcome of the program in the end. As indeed the screenshot is not made in the client side...
