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>
</servlet>
<servlet-mapping>
    <servlet-name>DownloadServlet</servlet-name>
    <url-pattern>/downloadFile</url-pattern>
</servlet-mapping>DownloadServlet.java:

Hi Pratibha,
I don't think you are getting the error due to the code which you have written here. You must have written some code that is causing the error. Put a breakpoint in your code and debug your code.

How to view the report of Upload and Download list

Hello,
I would like to see the Portal Activity Report of all the users who have logged in and out and their times and I would like to see the names also with how many uploades and downloades from the portal.
I can view only the user ids thats all in the Portal Activity Report.
Can anyone help me. Please
cheers
murali

Hi Murali,
KM access is not logged by the portal activity report so far.
You would have to implement it on your own. For an introduction see Documents hits count (KM Activity Reporting)
Hope it helps

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

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>

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...

Upload and download speed is horrible. it takes hours to download a movie from iTunes.

upload and download speed is horrible. it takes hours to download a movie from iTunes.

VangieChuck the problem is definitely not iTunes it is your ISP download provision. Either your ISP needs to make a service call and solve your bandwidth issues or you need a better service, granted it all depends where in the world you are located. In Kappy's and my neck of the woods we are use to 5 - 250 Mbps download rates with an average of about 25 mbps for most city dewellers. Upload will vary depending on your service.

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.

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!

dbms_lob.LOADBLOBFROMFILE(dst_loc, src_loc, dbms_lob.lobmaxsize, src_offset, dst_offset) ;
/* Closing the LOB is mandatory if you have opened it */
dbms_lob.close(dst_loc);
dbms_lob.filecloseall();
COMMIT;

bytes_rd := src_offset - src_osin;
dbms_output.put_line(' Number of bytes read from the BFILE ' || bytes_rd ) ;
/* Use the dst_offset returned to calculate the actual amount written to the BLOB */
bytes_wt := dst_offset - dst_osin;
dbms_output.put_line(' Number of bytes written to the BLOB ' || bytes_wt ) ;
/* If there is no exception the number of bytes read should equal to the number of bytes written */
END ;
