If you are using 'commons-fileupload.jar' then it is dependent on 'commons-io.jar'.
So, you have to keep the 'commons-io.jar' in your class-path.

Thank you very much Shahin.

Servlets can handle file uploads by way of the Apache Commons FileUpload library.

I want to store the txt file in database so that the same file i can retrieve and see the content. i will store file in db as BLOB. can you send me the servlet code.

Thank you for your reply.
