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.

Thanks in advance.You know one of the most key elements of getting help in programming is to post sections of code, or preferably, working examples and then ask specific questions on things you would like to improve, don't understand, or just doesn't work.
Without some displayed effort on your part, you are going to be fairly hard pressed to get any type of help.

Does anyone know how to upload and download files to the icloud storage?

Well, it says i have 5g of free storage... but what good is it? There doesn't seem to be any way to put anything there.
What am I missing here?

iCloud does not have a general file syncing service, like Dropbox or Sugarsync. Only certain types of files can be synced and only by applications/apps that specifically support these files and that support iCloud. For example, Pages can sync to iCloud and only Pages apps on devices can access these files. Within DocsToGo, nothing can be synced to iCloud.

Upload and Download Files in an Application

hi,
I'm use Application Express 2.1.0.00.39 and the procedure " How to Upload and Download Files in an Application" :
http://download-west.oracle.com/docs/html/B16376_01/up_dn_files.htm#sthref177
I do not find the following tables or view:
HTMLDB_APPLICATION_FILES or wwv_flow_file_objects$.
which it is my error?
thanks.
Luigi

The documentation was for version 2.2. I could not find a 2.0 version of this howto:
http://download-west.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm#CIHCFCHF
However, I did find the correct name of the view for my version, HTMLDB_APPLICATION_FILES
After following the instructions in the above-mentioned "how to" (uploading and downloading files), I am a getting a html 403 error (You are not authorized to view this page) when I try to download from my custom table using the procedure specified in the howto.
I've granted execute on the procedure to public only (as specified in the doco).
err nvm. This has already been answered,

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 can I upload and download files with uiXML?

I want to implement upload and download files with uiXML. In some previouse topic I got answare to look in AbstractPageBroker class in JavaDOC. I did it but this is a very-very little resolution description for this problem. I think for developers YOU (UIX Team) must in very quick time to put some examples on the NET because this is a nice technology but with adecvate samplase and developers guide it will be dead very soon. I digging this forum for information. I see many many people have same problems about this technology. They like it and want to use and try but documentation is very very poor.
WE WANT EXAMPLES and separate forum for UIX. I think it deserve this.
If You have any more detailed documentation would be nice to put on the net. I have uixdemo.zip file but this is in very early fase of development. I downloaded it before fwe months. And now I can't find it anymore on youre site. What happend?

Attila -
I went back and re-read the JavaDoc for AbstractPageBroker and MultipartFormItem and put together the following sample PageBroker based on the description from the JavaDoc:
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import oracle.cabo.servlet.BajaContext;
import oracle.cabo.servlet.Page;
import oracle.cabo.share.util.MultipartFormItem;
import oracle.cabo.servlet.xml.UIXPageBroker;
* An extension of UIXPageBroker which stores all uploaded
* files in the temporary directory.
public class UploadingPageBroker extends UIXPageBroker
* Override of AbstractPageBroker.doUploadFile() which saves
* all files to the temporary directory.
protected String doUploadFile(
BajaContext context,
Page page,
MultipartFormItem item) throws IOException
// Get the location of the file to create in the temp directory.
// Of course a real application probably wouldn't upload files to
// the temp directory - just using this contrived example to
// demonstrate basic uploading support.
File file = _getFile(context, item);
if (file != null)
// Create a FileOutputStream. Of course, a real application would
// probably want to buffer the output
FileOutputStream out = new FileOutputStream(file);
// Write out the file
item.writeFile(out);
// Close up the output stream
out.close();
// We can return a value here to add to the PageEvent
// if so desired.
return null;
// Gets the File for the item that we are uploading
private File _getFile(
BajaContext context,
MultipartFormItem item
// Get the file name
String name = item.getFilename();
// If we don't have a file, bail...
if (name == null)
return null;
// Get the path to the temporary directory
File dir = _getTempDir();
// Return the File object
return new File(dir, name);
// Returns the path to the temprary directory
private File _getTempDir()
// Get the temporary directory from the ServletContext
ServletConfig sConfig = getServlet().getServletConfig();
ServletContext sContext = sConfig.getServletContext();
return (File)sContext.getAttribute("javax.servlet.context.tempdir");
In this sample, each uploaded file is simply saved in the temporary directory. You'll want to replace the code that creates the FileOutputStream for the uploaded file to use whatever OutputStream makes sense for your application.
BTW - I used the following UIX page to test this out:
<?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://xmlns.oracle.com/uix/controller">
<content>
<pageLayout xmlns="http://xmlns.oracle.com/uix/ui">
<contents>
<form name="uploadForm" usesUpload="true">
<contents>
<fileUpload name="uploadedFile"/>
<submitButton name="upload" text="Upload"/>
</contents>
</form>
</contents>
</pageLayout>
</content>
</page>
Hope this sample helps with the uploading part of your question. I'll see if I can provide a download sample in a later post.

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!

Uploading and Downloading files in an Applicaiton

I was able to successfully upload and download files stored in the database through Application Express by following the how to instructions at -->
http://download-uk.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm#CJAHDJDA
QUESTION: Is it possible to retrieve the downloaded file without granting execute to the download procedure? My DBA is requesting that I remove the procedures public grant, but when I do, I can no longer download the file.

As long as the Oracle username with the connection has 'execute' on the package 'public' should not need execute. Though I do not use the tools in question so there may be factors I am unaware of, but Oracle wise the connected session needs execute. If can get it from public, a role, or a direct grant. I just say use role based grants or direct grants rather than a public grant to get the privilege.
