WWW Page Java Parser - Ctrl + C Ctrl + V

I'm new programmer in java and I have a problem with my parser. Exactly I try to get data from source page and i know how to do that.

But another www page doesn't have any data included in page source.

Is it possible to do using Java with data/text line on this page something like Ctrl+C and copy to file or wherever I want?

I have access only to view this page like evry normal users on Internet.

Thanks for your help!
