To Upload and Download an image

Hi Experts.
I have a requirement wherein i have to uplaod an image ( for eg: a screenshot of an error ).
Afer uploading i want to show the preview of that image and save the same in the database , so that later on i want to also download that image and show it next to the Text Area.
Any inputs would be helpful.
Thank You ,
Radhika.

Hello Radhika,
You need to create transparent table following fields e.g.
Field Name                Data Type
DATA          RAWSTRING
NAME          STRING
TYPE          STRING
Create the context for above mentioned fields and bind the properties of data, filename & mimetype with File Upload & Download UI elements
In WDA use File Upload & File Download UI Elements & Save button for saving the data file.
On Save action update the data base table.
Thanks
Vishal

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?

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.

Apex application file -upload and download a file.

hi
im having an issue with an application i created,its about uploading and downloading a file in application.the application is working and was able to upload and download a file but i have not idea there the file is stored in the application database,try to search for the file,its something dealing with the apex_application_file and i cant find it.
Any idea where the file is stored?
thnx
nivesh

Dear nivesh!
If you upload a file into an APEX application the file is temporarily stored in the APEX_APPLICATION_FILES table. If you close your current application page the APEX_APPLICATION_FILES table will be cleared. You should create your own table to store files in a BLOB column. I've create an example for uploading images into an APEX application on apex.oracle.com. If you want to have a look at it please use the following credentials:
Workspace: flo_demo
Username: dev_null
Password: password
Application: 61811
Yours sincerely

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?
Thanks in Advance,
Kindly Regards,
S.V.Selva Bala.

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,
S.V.Selva Bala.

How does cloud work out in the australian country where I have very slow upload and download speeds and have unreliable connections?

I really just cant get my head around how cloud works when I have such low access to internet downloads..

Under these conditions no service which relies on using a fair amount of bandwidth is going to work. In your situation you may be able to handle a moderate amount of email, calaendars and contacts, though it will be slow to load; but heavy uploading and downloading of for example images in Photo Stream is likely to take so long as to be impracticable.

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

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.
