File upload and download using jsp/servlets

How to upload any file to the server using jsp/servlets. . Help me out

You can also try the Jenkov HTTP Multipart File Upload. It's a servlet filter that is easy to add to your web-project. After adding it, you can access both request parameters and the uploaded files easily. It's more transparent than Apache Commons File Upload. There is sufficient documentation to get you started, and there is a forum if you have any questions.
Jenkov HTTP Multipart File Upload is available under the Apache license, meaning its free to use.

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.

Lasse

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?

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,

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?

The file upload and download

Hi all,
I am going to build a form and run on the web. I am going to do a form which intend to do the file upload and download (any type of file). How can I achieve it?
Also, once I put it on the web, I would like to do a 'web-like' function: when the user click on the file name, it can open it with the association with the browser (For instance, when I click on the *.doc file, it opens the word automatically). Is it poosible to do so and how to do so? Thanks first.

New User M.Senthil..

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>

Upload video by using jsp/servlet

Please help me asap.

You need to use the Oracle jdbc driver. Apparently, the Weblogic JDBC driver is being selected:
weblogic.jdbc.rmi.SerialPreparedStatement
The Oracle JDBC classes can be found in <ORACLE_HOME>/jdbc/lib/See <ORACLE_HOME>/jdbc/readme.txt for how to specify the correct class path in the application.
I would have thought that the oracle JDBC driver would have been selected (if in the classpath) or an exception would be raised if the Oracle JDBC driver was not found.... because the code should include:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
This should load the Oracle jdbc driver and classes, not the weblogic ones. IF the Oracle JDBC drivers are not found, an exception should be raised...

Tips or tools for handling very large file uploads and downloads?

I am working on a site that has a document repository feature. The documents are stored as BLOBs in an Oracle database and for reasonably sized files its not problem to stream the files out directly from the database. For file uploads, I am using the Struts module to get them on disk and am then putting the blob in the database.
We are now being asked to support very large files of 250MB+. I am concerned about problems I've heard of with HTTP not being reliable for files over 256MB. I'd also like a solution that would give the user a status bar and allow for restarts of broken uploads or downloads.
Does anyone know of an off-the-shelf module that might help in this regard? I suspect an ActiveX control or Applet on the client side would be necessary. Freeware or Commercial software would be ok.
Thanks in advance for any help/ideas.

Hi. There is nothing wrong with HTTP handling 250MB+ files (per se).
However, connections can get reset.
Consider offering the files via FTP. Most FTP clients are good about resuming transfers.
Or if you want to keep using HTTP, try supporting chunked encoding. Then a user can use something like 'GetRight' to auto resume HTTP downloads.
Hope that helps,
Peter

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
