  • Question on how-to Upload File tutorials

    Hello everyone,
    on page8-7 in HTML DB 2 day developer
    under the title of Store the document in a custom table:
    IF (:P2_FILE_NAME is not null ) THEN
    INSERT INTO file_subjects(id, NAME, SUBJECT, BLOB_CONTENT, MIME_TYPE)
    SELECT ID, :P2_FILE_NAME, :P2_SUBJECT, blob_content, mime_type
    FROM HTMLDB_APPLICATION_FILES WHERE name = :P2_FILE_NAME;
    DELETE from HTMLDB_APPLICATION_FILES WHERE name = :P2_FILE_NAME;
    END IF;
    :P2_FILE_NAME and :P2_SUBJECT are the expressions of bind variables.
    I'm thinking in the select statement, it should use the filed names of the table HTMLDB_APPLICATION_FILES, something like name and subject.
    but I tried select id, name, subject ...... I'm getting an error.
    my question is: are :P2_FILE_NAME and :P2_SUBJECT field names of the table HTMLDB_APPLICATION_FILES?
    Thanks for your reply,
    Emily

    Scott,
    Thanks for your answer. I can understand :P2_FILE_NAME and :P2_SUBJECT are bind variables. If I need implement an upload function, then I need to know the filed names in table HTMLDB_APPLICATION_FILES. How could I know that?
    Or should user always use the two bind variables in their own application?
    There is an expression in page 8-4:
    p?n=#ID#
    I can understand ID is a stubstition string. but I don't know what p?n stands for? I looked up in the HTML DB 2.6 user's guide. Unfortunatly, I didn't find a reference.
    In page 8-9:
    To change the download link to use the new download procedure
    step5: #OWNER#.download_my_file?p_file=#ID#
    when I try to download the files, I always get the same file, namely my work space name.
    and I don't understand the syntax of the above notation.
    Is there somewhere I can get a reference.
    Thanks a loooot for your reply,
    Emily

  • How do I find music that has been uploaded to iTunes from a purchased CD and iTunes is "unable to find the original file?" I no longer have the CD. I have tried all the usual methods of looking in my iTunes library and through Find. No Luck.

    How do I find music that has been uploaded to iTunes from a purchased CD and iTunes is “unable to find the original file?” I no longer have the CD. I have tried all the usual methods of looking in my iTunes library and through Find. No Luck.

    Backup drive?
    Subscribe to iTunes Match?
    If neither of the above and you don't have the CD and can't find your tracks on the computer then they you're stuck.  A file recovery utility will cost $100, plus another $100 for an external drive to which to resue the files, and may not even work.  You can buy a lot of CDs for $200.

  • In Blurb trying to upload an album that I have prepared in Adobe, but I can't find any Adobe files that way.

    I am in Blurb, trying to upload an album that I have prepared in Adobe ELements 10.  To upload I need to navigate in my computer to whatever Adobe folder has the album, but I can't find any Adobe files that way.  So I wanted to save the album to
    an external drive where I could be sure to find them for the upload
    But when I tried to copy the photo album, the dialog box said that the photos will be deleted from the main program.  I didn't like the sound of that, so I chose "Backup" which seems to have copied everything from Adobe to my eternal drive, not just the photo album that I want.  To make matters worse, but exported folder named for my photo album is not the group of photos that I assembled in Adobe.
    How do I upload directly from Adobe the program on my hard drive so I can be sure it is the correct assemblage of photos?

    The album photos are just the originals; there are no special copies in the album--it's just a list. Select the photos in the album, then go to File>Export as New Files and send the new copies where you want them.

  • OLT - Why can't it find my databank file after I've uploaded it?

    I got this last minute high priority load test dropped in my lap the last second so any help asap would be greatly appriciated! We've started using OpenScript, but not OLT yet so I'm trying to figure this out.
    All I'm trying to do is run a simple login script - it works fine and iterates through when I play it in Open script, but I can't get it to find the databank using OLT.
    1) I added my script to the scenario
    2) Then went to Tools - Upload file - and uploaded the .csv to the right repository - Upload was successful.
    3) On the Build Scenarions tab I go to the Configure Data Bank icon - my data base IS there, but when I click on it it says "Cannot find the databank file (repos=...rep name)
    Help! any ideas?

    I'm not sure if this is your problem, but one thing that was added recently is that OpenScript has a setting to store the databanks with a RELATIVE path.
    If you open your script, go to Script / Script Properties / Script Assets.
    If you then look at each databank, there is a checkbox "Save path relative to current script".
    You may have problems if you have a databank locally (whilst developing the script) but needs to be in the same place on the SERVER when actually running them in OLT. If you develop scripts purely on the server itself, this shouldn't be an issue.

  • File upload: problem with writing uploaded file to server-harddisk

    Hello,
    according to the example in the File upload tutorial, I tried to save an uploaded file to disk, but it didn't work (and also no messages / exceptions were thrown).
    The Javadoc for the function uploadedFile.write(filename) says that if the file should be written in an other directory than the servers' tmp-directory, the server.policy has to be adjusted.
    The following line is already included in my server.policy:
    permission java.io.FilePermission "<<ALL FILES>>", "read,write";
    So I have two questions:
    1) Where can I find the servers' tmp-directory?
    2) How should the sever.policy permission code look like?

    The File Upload tutorial at http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/file_upload.html has you save the uploaded file to disk. It also gives this information:
    The server holds the uploaded file in memory unless it exceeds 4096 bytes, in which case the server holds the file contents in a temporary file. You can change this threshold by modifying the sizeThreshold parameter for the UploadFilter filter entry in the web application's web.xml file. For more information on modifying the web.xml file, see the last section in this tutorial, Doing More: Modifying the Maximum File Upload Size.
    In cases where you want to retain the uploaded file, you have three choices:
    * Write the file to a location of your choosing, as shown in this tutorial.
    * Create an UploadedFile property in a managed bean and set it to the component's value before you exit the page (as in the button's action method).
    * Save the file to a database.
    By default, the File Upload component can handle files up to one megabyte in size. You can change the maximum file size by modifying the maxSize parameter for the UploadFilter filter entry in the application's web.xml file, as described in the last section in this tutorial, Doing More: Modifying the Maximum File Upload Size.

  • How to upload file from client to server

    Can someone please help.
    User needs to browse file on his desktop and upload file using browse button. This file should then be uploaded to the server. I am using javascript in the front end and servlet in the back.
    Any help will be highly appreciated.
    Thanks,

    Jakarta Commons FileUpload is the standard way of doing the file uploading these days. You can find source, binaries and documentation at the Jakarta Site http://jakarta.apache.org/ . The Commons has a number of subprojects, so start with the Commons libraries, then find FileUpload.

  • Is there a way to silently upload files?

    Ok, so I've taken the plunge. I've started working on an AIR
    app using Flash CS3. I'm putting together a little app that will
    keep my online store updated with all the product updates from our
    wholesaler. This includes parsing a csv file, downloading product
    images from the wholesaler, updating the database, and then
    uploading the images to our server.
    The problem is that AIR does not seem to have the
    functionality to silently upload files! Sure, I can use the
    file.reference object to fire off the browse method, which then
    opens the OS file browser window BUT I would really like the whole
    thing to be hands off. In the past, I've written these types of
    apps using Visual Studio but I haven't touched VS in two years.
    Has anyone run across a way to silently upload or ftp files
    in AIR?

    Hey Oliver,
    Thanks for your answer--the fact that it CAN be done has
    gotten me a lot further on finding a solution. Here's what I have
    so far. As it runs, I can see the progress and completion of the
    upload but I'm still not getting it saved. I'm uploading it to a
    ColdFusion processing page.
    AS3 Code:
    import flash.filesystem.*;
    import flash.net.URLRequest;
    //Silent File Upload (no browse window)
    function imageUpload(imageName,uploadPage):void
    trace('Starting Upload of ' + imageName + '\n');
    var myFile:File =
    File.applicationDirectory.resolvePath(imageName);
    var request:URLRequest = new URLRequest(uploadPage);
    request.method = URLRequestMethod.POST;
    myFile.addEventListener(ProgressEvent.PROGRESS,progressHandler);
    myFile.addEventListener(Event.COMPLETE,completeHandler);
    myFile.upload(request,"theFile");
    function progressHandler(event:ProgressEvent):void {
    var file:FileReference = FileReference(event.target);
    var pLoaded =
    Math.ceil(event.bytesLoaded/event.bytesTotal*100);
    trace(pLoaded + '% uploaded');
    function completeHandler(event:Event):void
    trace ('Upload complete.');
    var uploadPage = "
    http://www.aaronbday.com/upload_file.cfm";
    imageUpload("angelic_cat.jpg",uploadPage);
    Here's the CFM page:

  • Uploading Files to DMP for local storage (Failover ) in DMM/DMP 5.2 is not working

    Dear All,
    I face a problem in making failover on the DMP , I did the following:
    1- make the design and save the presentation the needed to be failover.
    2- from Advanced Tasks ---> File transfer to DMP or Server and select the presentation.
    3- in the Adanced Task ---> Go to URL you will find an automated file genrated .
    4- Go to Digtal Media Player and select the generated URL and select the DMP and press GO.
    in DMM 5.1 after the above steps,the player was restart and after it back it displayed the uploaded presentation.
    but now the system running with 5.2 and it is not working ,Can any one help me to make this in DMM/DMP 5.2?
    Thanks,
    Ahmed Ellboudy.

    Ahmed,
    Let's not worry about failover at this time.
    Let's just attempt to get the LOCAL presentation to play.
    Your steps appear to be correct for transferring the
    presentation to the DMP.
    * From the DMM-DSM, Select the action to play the presentation
      on the DMP in Question
    Does the Presentation play on the DMP?
    then
    * go to the advanced tasks on the DMM-DSM and find the
      GO TO URL for the presentation that you created.
      Copy URL to your clipboard.
    * Now go to the DMP-DM of the DMP where you transferred the
      presentation.   Go to the Display Actions-->URL to be displayed
      and Paste the GO TO URL here then press the GO button
    Does the Presentation play on the DMP?
    Let me know what you see....

  • Can you upload files from the iPad to a Web Browers

    I recently received an iPad and I love it. I would also love to leave my laptop at home and only use the iPad while I'm away. One thing I think is missing for this to be possible is the lack of a native filesystem, as far as I know.
    I know there are many apps that allow you to store and sync documents but I can't find a way to upload files to a website. For example, if I'm on a job site that requires me to upload my resume, the browse button on the browser is not active. I can't upload the files using the documents I've stored in Pages or in readdledocs.
    Does anyone else think this is a major shortcoming?
    Is there a way to do that I'm not aware of?
    You assistance will be greatly appreciated.
    Thanks,
    joe

    I had the same complaint. I actually stopped using my laptop for the iPad. It was frustrating having to go to the laptop just to upload a resume to career builder. I just downloaded iCab browser in the app store. I sent my resume to an external email account and signed in. You need to open the email through the iCab browser and download the file there. ICab has its own download drop box. I was able to them go to career builder and upload a resume without a problem. It may be a pain to start emailing files to yourself just to import them into the app but it's worth it not having to either copy and paste or go back to your laptop. Hope that helps and you found a job.

  • Uploading files to website not working with Safari in Windows 7

    Safari version: 5.1.7
    OS: Windows 7
    Hi,
    I am a website owner, and I have a feature on my site where users can upload large (up to 50MB) music files to my server. The feature works in Firefox on OSX & Windows platforms and it also works in Safari on OSX. The uploading feature is not working with Safari for Windows. Do you have any idea why and how to fix this? It can't be an issue with my server as it works in other browsers fine and works fine in Safari for OS X.
    If you have any information on how to solve this or things for me to try to rectify this for use with Windows operating system it would be much appreciated.
    Thanks.

    GREAT NEWS!!!!
    I have solved this issue myself with some help from my a user on Microsoft Forums. The issue stems from the mime type of each Browser Chrome, IE, & Safari for Windows defaults as audio/wav. When the mime type is changed to audio/x-wav everything works. Firefox defaults to audio/x-wav and when changed to audio/wav it DOES NOT work.
    Once I input some code in my .php upload page to change the mimetype if audio/wav is detected everything works GREAT!!!
    So Here is what you need to do: Find your upload page and input this code:
    echo "<p>MIME Type: ".$_FILES["file"]["type"]."</p>";   
    right before your "If/then" statement of file type. For me it was near line 30 in my upload.php page, but I'm sure this is different for everyone.
    This will detect and DISPLAY the default mime type of your browser on the error page when your upload doesn't work. Once you know what mime type works for your file type then you can change your "if/then" statement for mime type upload to change your mime type to the correct one.
    I don't want to give the code here, because I'm sure it's specific to your file types and your site construction, but this should lead you on the right track.
    ***This is the solution if you ARE NOT ABLE to upload any certain file in a certain Browser. It has to do with mime type construction***
    I hope this helps others like it helped me!!!!!

  • How do I find a corrupted file in a backup folder on my computer?

    I have recently had to replace the battery in my iphone, but before doing so, I had backed up the phone about 3 times, all saying they were successful.  And then I had erased the phone(before I realised the battery was the problem).  However when I went back to restore from the backup, it says that it cannot be restored because the backup is corrupt.  I read on one site that sometimes if a phone turns off or disconnects while backing, it might cause a corrupt file, and I think that's exactly what my phone did due to the battery issues.  The big question is, is it only specific files inside the backup folder that are corrupt?  And how do I find out which files they are?  Please help.

    Hi
    This can be an issue on other end ( server end ) as export to HTML works fine so Muse is exporting the files correctly but while exporting to external server if it stuck then we should check on server side if there is any problem related to specific file upload.
    As a workaround, you can use any FTP client and then upload the exported html files to root location.
    Thanks,
    Sanjit
