[renuka_anil]

Hi All,

Im new to forum and to java . Im devloping an application that uses HttpServlet for receiving request from mobile device.

Im uploading an image from mobile to server and saving it on server.

I am accepting one chunk in one request and saving it locally.
But i dont know how to save second chunk along with first. Means append next to previous.

Please need help. If any body knows please tell me.
If any can give code snippet then it will be great

Basically, what you need to do is save each chunk, and, when you have received all the chunks, you then retrieve them and process them.

If this is a small app on a single instance Web server, you can use a class with a static method to hold the chunks in a static HashMap. Be sure to synchronize! However, this will *not* work on a Web server farm.

You can also store the chunks in a database. That's a little more effort, but it will always work.

I suggest starting with the first approach as a prototype. Once the process works, use the database.
