How to upload and download any file from plsql through weblogic server

hi all,
how to upload and download any file from plsql through weblogic server? i am using oracle 10g express edition and jboss.
Thanks and Regards,

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...

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?

How to upload and download files using FTP to a server(webserver) in JSP

I have to upload and download multiple files Of(size >5 MB)using FTP to a
Server(webserver) in JSP
how to do that ?

Or he could create his own tag libraries, no? :)One supposes that, technically, one could create a taglib wrapper around an existing FTP library. There might be licensing issues with distributing that taglib wrapper.
Of course, one could find the FTP RFC online, read it, and implement one's own FTP client implementation, complete with a tag library access point.

          OutputStream     out = new FileOutputStream( new File(destFile) );
          int n = 0;
          byte[] buff = new byte[8192];
          while( (n = in.read( buff, 0, 8192 )) != -1 ) {
               out.write( buff, 0, n );
          out.close();

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

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!

Can u please send me a sample code to upload and download a file using java

Hi,
Please can u send me a sample code to upload a file and to download the same file from a remote server using a java servlets. The file should be read byte by byte.

Hi, Thank u.
Sorry, I forgot to attach a code. Here it is.
Actually i need to upload a file to a remote server and download it from a server to my machine. I'm trying it using servlets and using tomcat5.0 as a servlet container. Here i'm sening a code used to upload a file. Let me know whether it works. Only few lines are here.

Problems with How-to upload and download

I downloaded and followed the instruction listed on the Oracle HTML DB How To Documents site titled - Build a file upload and download application
I completed the exercise and am having the following problems:
1) The one download link that is working gives me a popup to download a file named XXXX from www.XXX-YYY.net. The actual file I am trying to download is called stinger.exe. Www.XXX-YYY.net is the name of the site where the HTMLDB is loaded. XXXX is the name of the customer. I don't know where it is pulling the customer name from when I do the download. The correct file name is displayed in the file list. However, XXXX is the file named in the dowload pupup and an unrecognized file type call XXXX is downloaded.
(Actual names are not being used.)
2) There are two other files in the list but when I click down load for them I get The Page Cannot Be Found Error.

Thanks for responding. Lol! Seriously found this old post and decided to attempt a little bit of humor with the more recent post. Sorry did not mean to create any negative energy. Smile!!
Do you happen to know anything about APEX in the cloud. Is it out yet?

To upload and download any file to the server

Hi,
I want to upload and download files into and from the server; as we do it in yahoo attachments. Give the location of the file, click upload, it must upload the file to the web server and click on the uploaded file, it should get downloaded. i want to do this in Application server.
Can anyone help me on this please......
Thanks in advance,,
Bala

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...
