    Way beyond me to figure that out, but at any rate, what code? It says "Page not found".

    A web browser as a term project? Are you going for your doctorate or Masters or something? That seems a bit hard, an entire browser!

    For future reference, please copy and paste the code into the post itself (be sure to flank the code with the code tags). To save the page simply, just save the html, and change all the links (url, img, etc...) in the page to full url links based upon the url of the webpage. If you wish to save as an archive, you must save all images and html into a directory, and redirect the image links to the downloaded images (changing the clickable links to full path). Cookies are a bit more difficult as you must send them on a per webpage basis based upon the cookie. Javascript is even more difficult as this is a language in and of itself.

    A web browser as a term project? Are you going for your doctorate or Masters or something? That seems a bit hard, an entire browser!




    Nope bro...I am doing my BSc...and I am a 2nd year student.....and well its not a browser with full functionality.....its beyond my capability now

    That's a lot of code. Could you reduce it to just the portion that deals with with the question at hand (ie saves)?

    Read my post above. You need to get the webpage html. Then parse the html to look for <img src=""> tags, for each of these you download the image to local and change the webpage html to reflect where the images were saves (for example if you save the page to a folder named web, and your images to web/images, you change the img src="" to point to images/imagename). Then you must parse the html to look for links, changing each <a href="" to a full path link. Then lastly save the modified html.

    We can help guide you when you have problems, but will not do your assignment. Given the above descriptions, you should have more than enough information to get started. If not, here's more.
    For files: Lesson: Basic I/O (The Java™ Tutorials > Essential Classes)
    For parsing, see String and/or Lesson: Regular Expressions (The Java™ Tutorials > Essential Classes)
    Being short on time is no excuse to ditch the learning process.
