Web upload and download

Can Apple add support for upload and download function on iOS Safari? I know Apple will have restriced access to its storage, but upload/download from or to DropBox maybe be the best solution. When click the upload link, it can chose file from DropBox and upload to web. or when clicked a download link, it would pop an option to download to DropBox, that whould be the best.

Can they? Probably. Will they? Who knows.
Your best bet is to send them feedback via their feedback link.
apple.com/feedback
Also there are some browsers that support uploads and download like that.
iCab Mobile is often suggested for that.

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,

So, apart from putting FileUpload UI on your view, you have to implement a method which will do the actual uplod for you.

File upload and download through web Dynpro2.0.9. with Java

Hai All,
      I am working in web Dynpro2.0.9 with Java.For file upload and download "IWDResource" is used.But this package is not available in web Dynpro2.0.9.How to download and upload files through using this version?
      Anyone can help me?

Hai Noufal,
    I successfully upload the files to the database.
    For file download i create two views.
   In the first view files are fetched from the database(datatype for the file is image in the database)and it is converted to byte from image.Afterthat the byte is converted to string by using the following code.
byte source[]=new byte[1024];
                    if(rs.next()){
                         source=rs.getBytes("cv_document_file");
                    String sourcestr=source.toString();
                    wdContext.currentContextElement().setDownloadfile(sourcestr);
        Now i put the converted string into the second view.In the second view i try to convert the string value into bytes by using the following codes.
String sourcestr=wdContext.currentContextElement().getDownloadfile();
         byte bs[]=new byte[1024];
         bs=sourcestr.getBytes();
         wdContext.currentDownloadElement().setDownloadfile(bs);
         But it doesn't work and no error.
         Now i am expecting the valuable suggestions from you.
Thanks in Advance,
Kind Regards,

Hi,
Well,i don't know whether if this helps people here are not.
It is always a good practise to do it via Servlet and then download content.
The adavantage of doing this is
1). You may not need to pack the downloadable with the .war which you ultimately genrate which ceratinly help us in terms of faster deployment.
3). You may update the new content just by moving a file to the backup folder.
2).One may definately download the content irrespective to the content/file.
Hope example below helps..
Configurations:
In the above example we are assuming that we placing all downlodable file in D:/webapp/downlodables/ and you have configured the same path as a init param with the name "filePath" in your web.xml.
something like the one below.
<servlet>
    <servlet-name>DownloadServlet</servlet-name>
    <servlet-class>com.DownloadServlet</servlet-class>
    <init-param>
       <param-name>filePath</param-name>
       <param-value>D:/webapp/downlodables/</param-name>
       
    </init-param>

The file upload and download

Hi all,
I am going to build a form and run on the web. I am going to do a form which intend to do the file upload and download (any type of file). How can I achieve it?
Also, once I put it on the web, I would like to do a 'web-like' function: when the user click on the file name, it can open it with the association with the browser (For instance, when I click on the *.doc file, it opens the word automatically). Is it poosible to do so and how to do so? Thanks first.

About "Upload and download files from ADF into blob type colum."

hi
Using JDeveloper 10.1.3.3.0 I have tried the example available for download from this blog post by Jakub Pawlowski:
"Upload and download files from ADF into blob type colum."
at http://kuba.zilp.pl/?id=1
First a thank you to Jakub for this interesting example.
I have a question about a PDF file that I uploaded using the example.
The file has a size of 10445518 bytes.
After I upload that file, the blob column has a value with a size of 10445516 bytes, 2 bytes less.
SQL> select file_name, dbms_lob.getlength(stored_file) from blob_table;
FILE_NAME
DBMS_LOB.GETLENGTH(STORED_FILE)
ADF-DeveloperGuide-4GL-B25947_01.pdf
                       10445516If I download that file using the example, it has the same size as the blob value, 10445516 bytes.
If I open the downloaded file, using Adobe Reader 8.1.1, it first shows this message:
"The file is damaged but is being repaired."
After that, there is not problem using the PDF file in Adobe Reader.
I have tried this with both Internet Explorer 6 and Firefox 2.0.0.11.
I have also tried this with other (smaller) files, and those upload and download correctly.
question:
Why are those 2 bytes lost during upload?
many thanks

Hi!
I can only post you my code that works for me and as I said I had same problems but can't remember what solved them. My code:
public void fileUploaded(ValueChangeEvent event)
    FacesContext fc = FacesContext.getCurrentInstance();
    UploadedFile file = (UploadedFile) event.getNewValue();
    if (file != null && file.getLength() > 0)
      // here I have some messages written and a call to the method on AM to save the uploaded file to the DB
private BlobDomain newBlobDomainForInputStream(InputStream in)
    throws SQLException, IOException
    BlobDomain loBlob = new BlobDomain();
    OutputStream out = loBlob.getBinaryOutputStream();
    writeInputStreamToWriter(in, out);
    in.close();
    out.close();
    return loBlob;
private static void writeInputStreamToWriter(InputStream in,
                                               OutputStream out)
    throws IOException
    byte[] buffer = new byte[8192];
    int charsRead = 0;
    while ((charsRead = in.read(buffer, 0, 8192)) != -1)
      out.write(buffer, 0, charsRead);
   * Launch the upload - see fileUploaded() for actual upload handling.
   * @return null navigation event - we stay on this page
public String UploadButton_action()
    if (this.getMyInputFile().getValue() == null)
      FacesContext context = FacesContext.getCurrentInstance();
      FacesMessage message =
        new FacesMessage(FacesMessage.SEVERITY_WARN, JSFUtils.getStringFromBundle("fileupload.emptyfielderror"),
                         null);
      context.addMessage(this.getMyInputFile().getId(), message);
    return null;
   * Setter for inputFile UI Component.
   * @param inputFile inputFile UI component
public void setMyInputFile(CoreInputFile inputFile)
    this.myInputFile = inputFile;
   * Getter for inputFile UI Component.
   * @return inputFile UI component
public CoreInputFile getMyInputFile()
    return myInputFile;
}fileUploaded is a valueChangeListener on inputFile and UploadButton_action is as the name says the action for upload button.
Hope this helps. If not, than your problem is probably not the same as mine was, although the message about file corrupted was the same.
Next thing you can check in this case is if your file exceeds max file upload size. I don't know the exact default value, but if the file is too long I think this upload logic will upload only a part of the file and save it to the DB which can also lead to the same file corrupted error.
You can set the max upload value in web.xml like this:
<context-param>

<param-name>oracle.adf.view.faces.UPLOAD_MAX_MEMORY</param-name>

<param-value>5120000</param-value>
</context-param>
<context-param>

<param-name>oracle.adf.view.faces.UPLOAD_MAX_DISK_SPACE</param-name>

<param-value>15360000</param-value>
</context-param>

hi bala ,
for a windown server u can use VNC (virtual network connection) which opens a session on u r desktop later u can drag and drop form there vice versa and for a linux box you can use Win SCP which helps to open a session with interface to u r desktop in both cases you can upload and down load files very easiy just as we drag and drop items in a simple pc .. we use the same technique...

At least that is what the code you posted suggests to me.It looks like that to me too.
I believe that
URLConnection urlc = url.openConnection(url);Will return you an FTP URLConnection implementation if you pass it a ftp:// url
So for simple FTP ops, you don't need any external libs.
Actually, looking at your code, this is already what you are doing, so I really don't get this:
am not using FTP server..... i want to implement in my system only ....So How i will do.
Can you give me any idea based on this code Can you explain a bit more what you need?
