Uploading and downloading blobs without wwv_flow_files

Hi,
I am currently working on oracle 10g database and application express.
i went throu the material to upload and download images, pdf from a htmldb book.
it was excellent material. but the book only gave example about loading and downloading images, pdf through flows_files.wwv_flow_files view.
it seemed like we can only d/l the pdf, images and display on htmldb report only throu flows_files.wwv_flow_files view, as in the case of the script below
select
   wff.id, htf.anchor( 'p?n=' || wff.id, wff.filename ) filename_1,
   wff.filename filename_2, ed.abstract abstract
from
   wwv_flow_files wff, easy_document ed
where
   wff.name = ed.name;but is there a way to load and download images, pdfs from my own tables without the involvement of flows_files schema.
if then how can i modify the above code to get the pdf from the following table
TableA (vessel number, cruise number, pdf blob)
here for every (vessel, cruise) combination there is a pdf.
how can i get this pdf displayed in my htmldb report.
Can someone guide me please.
Thanks,
Philip.

Hi,
I tried the document link you gave and it looks like, i can directly download pdfs from my own tables without needding to upload to wwv_flow_files_objecst$ table.
i modified the procedure in the document accroding to my requirements and it worked.
in my page i show a grid with the parameters and the pdf documentname as download link.
when i click on the link a popup window with the option to save or open comes up.
but the popup window shows the filename as my procedure name through which i pass the id for the pdf document instaed of the filename which is shown as download link on the page.
How can i change this popup window filename to the default file name shown in the download link.
so that everytime i select the parameters, the page shows the pdf filename as link and on clicking the link the popup window should be able to show the same name shown as link.
i think this can be set either at the procedure level or at the page level.
and this is the following contents of the procedure
--        SET UP HTTP HEADER
               -- use an NVL around the mime type and
               -- if it is a null set it to application/octect
               -- application/octect may launch a download window from windows
               owa_util.mime_header( nvl('PDF','application/octet'), FALSE );
                -- set the size so the browser knows how much to download
                 htp.p('Content-length: ' || B_LEN);
                -- the filename will be used by the browser if the users does a save as
-- htp.p('Content-Disposition: attachment; filename="'||'CR'||VES||CRU||'.PDF'|| '"');
                -- close the headers
                owa_util.http_header_close;
                -- download the BLOB
                wpg_docload.download_file( BREP );and this is what i did at the page level. for that particular column i went to link option and the foll is what i gave:
Link Text: CR#VESSEL##CRUISE#.PDF
Link Attributes: target="_blank"
URL: #OWNER#.PROC_DOWNLOAD_PDFS?V=#VESSEL#&C=#CRUISE#
Here the link text is the filename that i wanted to show when saving the file.
Can someone guid eme please.
Thanks,
Philip.

Upload and download files from ADF 11g into blob type colum

Hi Guys ,
Anybody help me how to upload and download the *.pdf / *.doc file in blob object in ADF 11G.
Thanks ,

You should try the JDeveloper and ADF forum. This is the Oracle FORMS forum.

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

How to upload and download in BLOB?

I tried webutil but is not working properly according to my needs is there any other way to upload and download files in BLOB?
If any body knows solution please tell me.
Regards,

Dear Colleague,
In my Forms application, I use the WEBUTIL to load files into a BLOB column. However, prior to getting WEBUTIL to work, I loaded files into the BLOB column using the following PL/SQL code.
Note, that the example assumes that the row already exists in the table and you are updating it by loading the file into the BLOB. You will also be required to first create a Database Directory object (in my case, it was called "RKMS_DOC_DIR")
I do not have an example for downloading, as I use the WEBUTIL functionality for this.
Good luck!

File Upload and Download in Oracle iAS PL/SQL Gateway

i'm using the example 113471.1 to "File Upload and Download in
Oracle iAS PL/SQL Gateway"
when i press the submit button after i select a file to upload
i get the next message in the browser "No se puede mostrar la
pagina" HTTP 404 file not found.
I think the problem is in ctnsample.upload_form in the line
htp.formOpen(curl => 'cntsample.upload', cmethod => 'POST',
cenctype => 'multipart/form-data');
The ctnsample.remove work fine.
Could you,help me...

There is a document in the Oracle 9iAS 1.0.2.2 Library titled "Using the PL-SQL Gateway" Part Number A90099-01.pdf that explains file upload and download through modplsql. In particular there is a section there titled "Direct BLOB Download" which explains how one can easily download a blob utilising the wpg_docload package.
I am still concerned that there exist duplicate copies of my blob content. One copy in the wwdoc_document$ table, and one in my custom table.
Dmitry/Oracle can you confirm this?

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
Jan Vervecken

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>

How to upload and Download the file in a system through java programing

I am trying to upload a file as well as want to download the uploaded file in my system....I don't have any server an all.
I want to implement this in my system only .
I got this code but i don't know ,where i have to make the change and what are the parameters i have to pass.
can any one help me on this code ....please
here some piece of code
File Upload and Download Code Example
package com.resource.util;
public class FileUpload
public void upload( String ftpServer, String user, String password,
String fileName, File source ) throws MalformedURLException,
IOException
if (ftpServer != null && fileName != null && source != null)
StringBuffer sb = new StringBuffer( "ftp://" );
// check for authentication else assume its anonymous access.
if (user != null && password != null)
sb.append( user );
sb.append( ':' );
sb.append( password );
sb.append( '@' );
sb.append( ftpServer );
sb.append( '/' );
sb.append( fileName );
* type ==> a=ASCII mode, i=image (binary) mode, d= file directory
* listing
sb.append( ";type=i" );
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
try
URL url = new URL( sb.toString() );
URLConnection urlc = url.openConnection();
bos = new BufferedOutputStream( urlc.getOutputStream() );
bis = new BufferedInputStream( new FileInputStream( source ) );
int i;
// read byte by byte until end of stream
while ((i = bis.read()) != -1)
bos.write( i );
finally
if (bis != null)
try
bis.close();
catch (IOException ioe)
ioe.printStackTrace();
if (bos != null)
try
bos.close();
catch (IOException ioe)
ioe.printStackTrace();
else
System.out.println( "Input not available." );
}

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?

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

TS3989 the uploading and downloading of photos in photostream is not working, it used to work. have gone through all the setups. checked that everything is on. using windows7 pc. any ideas ??

photostram has stopped working between iphone and pc, uploading and downloading. I have gone through all the setups, made sure everthing is on but still no luck. Any ideas??

Frank-
Thanks for the suggestion -- I hadn't tried that but just did and it still doesn't seem to work. Would the binding cache AttrDefs separately from results?

Using CSA to filter MSN Messenger file upload and download

How would i go about filtering out the file upload and download functionality in messenger ?
I've already disallowed the possibility of uploading or saving from Messenger by not allowing the program the read or write files. But when a PC without this policy on it uploads to a CSA protected host. The CSA will download the entire file but then refuse to save the file.
I'd rather disallow this functionality alltogether ? my guess are that i would hae to do some COM filtering ?
I'd be greatfull for any hints you might have.
Best Regards,
Lasse
