Downloading files from a browser

I need to write an app that will download files from our clients and put it on our server. It is client initiated process from a browser.
I know the html type is "type=file" and when the user clicks it it brings up a file dialog. Then they can select a file name from their hard drive.
Now, when the user hits "submit" I want the file to download to our server. But how can I get an http servlet to control this process?

First of all, download is when data comes from somewhere to your local machine, Upload is when you send data from your local machine to somehwere. So, you are looking to UPLOAD data.
Second, if you search on here for references to 'upload', you will find exactly what you are looking for.

  • Can't download file from any browser and download manager

    i confused wit my MBP, becaus MBP can't download file from internet ( via USB modem & Wi-fi)..

    i use iGetter, and it not responding to download, safari too..

    I was able to download the trial from rarlab.com. What happens when you click on a download? You need to make sure you select to download the Mac version. The .exe files do not run on a Mac.
    BTW, you might want to check out GUI Tar  https://www.macupdate.com/app/mac/14503/gui-tar
    The other two sites also work for me. What exactly happens when you click on a link to download? Do you know how to find your downloads?

    How do I move a downloaded file (from You Tube) to Garagband - so as to separate video from audio (which I will send to iTunes)

    Create a new GarageBand "Movie" project, then import your movie into GarageBand, by dragging it from the "Movies" tab of the Media Browser into the Timeline. GarageBand will split the movie into a video channel and an audio channel. Delete the video/movie channel and use the "Share" menu to send the audio channel to iTunes (assuming you have iLife '11 GarageBand)

  • Where can i get an example of Viewing wap, downloading files from wap site?

    as we know, almost every simulator has this function. now i wanna write the same function via MIDP, how?
    And, anyone know nextel i730, it's very weird that it cannot download file from the wap site but other phones can do it from the same site.
    any help would be appreciated.

    WAP = HTTP. Just open a http page in midp and read the data. Displaying WAP in MIDP is another thing, since it does not have facilities for that. Why should it anyway? All phones that hava java, already have a W(AP/EB) browser.

  • Help required with downloading files from inside WEB-INF folder

    I am working on a web application and I have an upload script which uploads different files to a foler called 'uploads' . To stop users from accessing the folder content I have put it in the /WEB-INF/.
    In my JSP file, I used to link to the uploaded files like this before for users to download them :
    if(filesListIterator.hasNext()
    files = (FilesBean)filesListIterator.next();
    <tr><td><a target="_new" href="<%=files.getFileName()%>">"<%=files.getFileName()%></a></td></tr>
    }I need to know how to alter the above link to make it access/download files from the /WEB-INF/uploads/ while still restricting direct access to the files.
    Thanks

    Anything under WEB-INF is not directly accessible via the browser/ client. You could try defining the JSP/ Servlet inside web.xml deployment descriptor and see if you can access the file from there.
    I think a better way to accomplish this would be to keep the file outside WEB-INF , and use other techniques to protect the folder that contains the file - for example password-protection, or defining a .htaccess file and serving a 403 Forbidden error.

  • Why can't I download file from any websites?

    Whenever I try to download files from filesharing sites like mediafire, I click the download button and the page appears to be loading and nothing happens.
    After several tries, I found out that while the page is loading, it is actually downloading the file because the time it takes for the page to load before the "open" or "save file" windows come out depends on the size of the file. And immediately after I click "save file" the download is done, and I can open whatever I downloaded. The time ranges between 5min to 30min depending on the file size.
    Usually the "save file" window will display immediately when I click on the download button, the the fire fox download window will show the progress of the download and % of completion. But no, for me nothing appears in the download window, and I don't get to see the progress of my download until it is apparently "completed" after the webpage finished loading.
    I have tried every solution that I know, cleaning my browser history and cookies, resetting firefox, clearing up my computer's registry, even did a clean reinstall of firefox, wiping everything including my bookmarks, but none of these solves the problem. I am also pretty sure that my firefox extension are not the ones to blame as I did do a test download after a clean reinstall, which did not work as well.

    My problem is fixed after I set the firefox connection settings from "use system proxy setting" to "no proxy". After setting to no proxy, the downloads happens as it should.
    but my question now is what is system proxy? and what is the difference between using these 2 different options?

    It seems to work again but can I get rid of opening permission request please? I may have 2 versions of the browser in the computer or the new program did not replace the old?

    Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
    '''Note:''' You might want to print these steps or view them in another browser.
    #Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
    #After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
    #Delete the Firefox installation folder, which is located in one of these locations, by default:
    #*'''Windows:'''
    #**C:\Program Files\Mozilla Firefox
    #**C:\Program Files (x86)\Mozilla Firefox
    #*'''Mac:''' Delete Firefox from the Applications folder.
    #*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
    #Now, go ahead and reinstall Firefox:
    ##Double-click the downloaded installation file and go through the steps of the installation wizard.
    ##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
    Please report back to see if this helped you!

  • Download file from ftp server

    Can I download files from an ftp server by simply using the ip address or https:// url?    I've only gotten this to work by using the "ftp//:" address in previous projects and I'm not getting this to work in many different attempts.

    Hi!
    You don't need to specifically use an IP address. E.g can use
    $FTPHost = "myrandomserver.mycompany.com"
    $Username = "admin"
    $Password = "12345678"
    $FTPFile = "test.log"

  • Uploading and downloading files from a web app (Urgent!!)

    Hi everyone:
    I'm developing an application in PL/SQL to upload and download files from an HTML webpage. I congured the document table and the parameters necessary in the DAD of my application.
    when I upload the file using my webpage that file info is automatically uploaded to the doc table. This is as far as I have gotten.
    I need to do the following:
    - Place the uploaded file into a column in another table in my database as part of a text message (think of it as an email message), and delete the file from the doc table (as this is thought to be a temp table that holds the file when uploaded from my webpage)
    - Retreive the file so that it can be downloaded from another web page.
    The file can be a PDF, WORD DOC, etc...
    I now that I can do this with InterMedia but I haven't figured out how :(
    Can anyone please point me to an example or some documentation that can guide me through the process.
    DB VERSION: 8.1.7
    IAS VERSION: 1.0.2.2
    Thanks,
    Carlos Abarca

    The idea was for you to look at the code and get an idea of how to access the BLOB in the document table. IF you look at the procedure
    insert_new_photo( new_description IN VARCHAR2,
    new_location IN VARCHAR,
    new_photo IN VARCHAR2 )
    It shows how to access the blob that is stored in the document table. You can then copy this blob to your own table using the DBMS_LOB package.
    Hope this helps,
    Larry
