    Default Access to a shared folder over LAN

    Hello, everyone. I would like to know how to connect to and gain access to a shared network folder. I presume I need a login for that share folder. Can a URL construct be used?

    Use whatever the address of the file is (in general it's //{computer address}/{rest of address})

    So, for example, to access a computer with an ip address of 192.168.0.4 inside a folder called share:

    File file = new File("//192.168.0.4/share/theFile.txt");

    If you can access the other computer via the name, you can just use the name instead of the IP address.

    File file = new File("//HostComputer/share/theFile.txt");

    Lastly, you can access via the url as well.

    File file = new File("http://www.javaprogrammingforums.com/java-networking/4902-access-shared-folder-over-lan.html");

    Thanks for your speedy response. What I did already is exactly what you (or anyone else) probably would have suggested. My real problem is: creating the file object from the actual path works. However, what if the share folder needs authentication, which is the case with most Windows machine.

    Before I go any further. I probably should ask for suggests to the best possible route to achieve the follwoing:

    1. I want to get a file name externally ( the name of an image file, .jpg)
    The file names are within Oracle database. This part is fairly easy.

    2. Search a remote folder ( the share folder on the LAN that contains all the image files; the share folder requires authentication.

    3. Return the image file when found.


    The found image file will be used in a HTML context. I am not sure how to implement this.

    Im thinking about just returning the absolute path to the image file when it is found, this path will be embedded in the img tag. As I said I am not sure how to proceed. SUGGESTIONS PLEASE.

    Would an applet carry out this function?
