Download file from button

Hi Guys,
I followed thread 214709 (download blob from table) and had similar code in my Portal app. I have a stored procedure with almost identical code. My page has a drop down list which shows the last 12 sales files a customer can download. Behind it I have a Download Button.
The procedure gets executed but the download window does not show up. If I put the call in a before header it actually works so nothing is wrong with the code. Where do I have to put the call and do I have create an additional branch. After download theu user should stay on that page. I actually have 3 sections with 3 buttons to download or request a file to be emailed.
So my last question is what is best practice in this situation.

the thread you followed...
Downloading BLOB from a table.
...showed you how to make a procedure similar to our P procedure that's used to fetch blobs out of a document table. once your file download procedure works, you can call it from the web in one of three main ways:
1) using an image tag as shown in File Upload ( again! )
2) using an anchor tag as shown at the top of File download-upload
3) directly calling it from the URL. this is effectively the same thing as clicking on a link from an anchor tag in number 2, above.
it sounds as if your download procedure's working because you said it works if you call it before_header. i'm gathering from your post that you are currently trying to call your download procedure in some kind of after submit process. you're finding that your procedure's executing, but you don't see your file. i just set up a test case for this and found that if my page didn't have a branch on it, my after_submit process did render my image correctly. it doesn't sound as if this is what you're shooting for, though. it sounds as if you just want a select list that allows users to select a particular doc. after selecting a doc and clicking a button on your page, the user is allowed to download the doc while still being left on your original page. if so, how about creating a button that calls a javascript procedure that checks the value of your select list and returns a rendering of that image? if that's what you're after, you could do it by adding javascript like...
<script language="JavaScript" type="text/javascript">
function viewSelImage (theItem)
var selVal = document.getElementById(theItem).value;
var url;
url = 'getmyfile?p_id=' + selVal;
location.href=url;
</script>
...which, of course, assumes your document download procedure is publicly executable and named "getmydoc". it also assumes that getmydoc accepts p_id which corresponds to your document table. then, assuming your select list item is called P1_MY_IMAGE_IDS, you could add a button to your page that has a URL target of...
javascript:viewSelImage('P1_MY_IMAGE_IDS');
...and that would popup a call to your document download procedure while leaving the user on the same page... which i believe is what you're after.
hope this helps,
raj

DMS - Download File from CV03n

Hi guys!
Is there some function or BAPI, that can I make donwload file from cv03n and move to another server or save file content in internal table?
I need develop the abap program that download file from cv03n and put in another unix adress, that is possible?
thanks

Hi,
if you have the document data (number, type, ....) you can use the report DMS_KPRO_READ. This report will list all originals of this document info record and with the small green download button you can easily download the file to your desired directory.
Best regards,

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?

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>

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.
Here is one...
# FTP Config
$FTPHost =
"10.10.10.5"
$Username =
"admin"
$Password =
"12345678"
$FTPFile =
"test.log"
# FTP Log File Url
$FTPFileUrl =
"ftp://" +
$FTPHost +
"/" +
$FTPFile
# Create FTP Connection
$FTPRequest =
[System.Net.FtpWebRequest]::Create("$FTPFileUrl")
$FTPRequest.Credentials
= New-Object System.Net.NetworkCredential($Username,
$Password)
$FTPRequest.Method =
[System.Net.WebRequestMethods+Ftp]::DownloadFile
$FTPRequest.UsePassive
= $false
$FTPRequest.UseBinary
= $true
$FTPRequest.KeepAlive
= $false
# Get FTP File
$FTPResponse =
$FTPRequest.GetResponse()
$ResponseStream =
$FTPResponse.GetResponseStream()
$FTPReader =
New-Object System.IO.Streamreader
-ArgumentList $ResponseStream
do
Write-Host
$FTPReader.ReadLine()
while ($FTPReader.ReadLine()
-ne $null)
$FTPReader.Close()
# Create FTP Connection
$FTPRequest =
[System.Net.FtpWebRequest]::Create("$FTPFileUrl")
$FTPRequest.Credentials
= New-Object System.Net.NetworkCredential($Username,
$Password)
$FTPRequest.Method =
[System.Net.WebRequestMethods+Ftp]::DownloadFile
$FTPRequest.UsePassive

-ArgumentList $ResponseStream
do

$FTPReader.ReadLine()
while ($FTPReader.ReadLine()
-ne $null)
$FTPReader.Close()

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"
# FTP Log File Url
$FTPFileUrl = "ftp://" + $FTPHost + "/" + $FTPFile

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

What type of file? From what site? What Apps have you downloaded for it?
Perhaps if you provide details of what you are doing we can provide more precise help.

How do I move a downloaded file (from YouTube) to GarageBand so as to separate video from audio, then send audio to iTunes?

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)

DATA TRANSFER - How to get a SINGLE SPACE in the downloaded file from UNIX?

Hi Experts,
Am sending data from SAP to UNIX/ Application server and text file on desk top as well.
So, I am keeping a single character just SPACE at the END of each record.
Then, When I see the downloaded text file, I found a SINGLE SPACE at the end of each record, fine.
Then, by using CG3Y t code, I downloaded the UNIX file to my desk top.
But, When I see this UNIX downloaded file from UNIX, I did NOT find any SPACE at the end of each record!!!
Am doing every thing same in both cases.
So,
1 - Why its happening in case of UNIX file?
2 - How to get a SINGLE SPACE at the END in the downloaded file from UNIX?
thanq

Hi,
I don't know if this works:
perform SET_TRAIL_BLANKS(saplgrap) using 'X'.
perform SET_FIXLEN(saplgrap) using '0' '060'. "put length of your line from-to
... download ...
It will put space at the end of your line, according to the length.
Hope it works,
Chang

Result of this code is : there is a pop up asking to open or save pdf format and process is complete, but i have problem in downloaded file.
At the time of creation i have put BMP image for signature in PDF file and it is working fine but when i upload that file in Application server and then download it with above used code it save the PDF file but when i open that file so whereever i have used signature that page gives error and could not display that scanned signature.
Can anyone please help me in this regard.
or is there any possibility from which i can download that file just like File transfer from BSP.
Keep in mind that i am using BSP technology so all GUI based function module to download file are not working.
waiting for your reply.....
Regards,
Gagan
