please reply as it is needed to complete my project to submited to the collage

With SQLJ you can do it.
When you look at:
http://otn.oracle.com/sample_code/tech/java/sqlj_jdbc/files/basic/basic.htm
or
http://otn.oracle.com/sample_code/tech/java/sqlj_jdbc/files/advanced/advanced.htm
There are samples for reading LONGRAW / BLOB from Database. If you want use it in servlet you have to pass the result to the responce object, set the correct mime-type and set the response.setContentLength( xx). This is for some PlugIns nessessary (pdf).

How to download a file from a server

Hi,
I have a question with a general design implementation. Hope anyone more skilled than me helps me.
I want to do an application based on an android client and a java server. Local wifi transmission, no 3G.
Basically, the client must connect to the server and request a file to download using a code.
How can I do that?
Things I know:
* I must create a background thread in the client to create a file in the SD card and update a progress bar using a Handler to communicate with the UI thread.
* The server must be multithread and non-blocking.
* The file is a binary file like a mp3 audio. So the server has to:
1. Send information about the file: name and total length.
2. Open the file, read and send bytes while it does not reach the end.
* The client has to:
1. Receive the information about the file and create an empty file.
2. Read bytes and dump them into the empty file. Update progress bar.
3. When all bytes are recieved close the file.
I have knowledge implementing a client and server in C (very awful) but I am beginning with a real client-server application done in java.
Questions:
* How can I download a binary file like an mp3 from a server to a client?
* Where I have to put my server application? I supose that I must create a jar, save it on a folder and execute it at PC start-up, right?
Thanks!
PD: I know this is not an android forum but I only need help with the download process.
Edited by: user13425637 on 06-dic-2010 11:08

Questions:
* How can I download a binary file like an mp3 from a server to a client?There are a ton of examples on the internet on how to download files. If you are having a problem, please post your code.
>
* Where I have to put my server application? I supose that I must create a jar, save it on a folder and execute it at PC start-up, right?Your server application will exist on a server and will run the application. hence the reason for the server. The best best for you is to read some online tutorials on client/server and how it works.

How to download a file from Middleware server

Hi,
I have a requirement to list file names in a table layout and when user clicks on file name, file must be downloaded to the client tier. Source files are located in 11i Apps middletier.
I did not find any examples on how to achieve this using OAF. All I see is downloading file from BLOB inside a database.
please help..

OAMessageDownloadBean is the bean that lets you download a file from middletier.
Please see the File Upload and Download chapter in devguide for implementation details.

How to download a file from a server path?

Is it possible to attach files on the server to a web dynpro response with cl_wd_runtime_services=>attach_file_to_response? All the examples I have seen assume you have the file content as an XSTRING. But how can one just send a file from a known path?
Is it really necessary to first load the file (e.g. a 50Mb TIFF) as an XSTRING before downloading it? If so, how is this done?

Hi Marc,
Try using this FM to convert String to Xstring.
SCMS_STRING_TO_XSTRING
HR_KR_STRING_TO_XSTRING
and also check this...Error document.getElementById(...) in function 'SCMS_STRING_TO_XSTRING'
Might Helps you.
Cheers,
Kris.
