Upload a zip file, unzip and read file

Question

Hi,

i am using NetBeans, and i am working on a jsp page that allows the upload of a zip file. The zip file contains 6 CSV files, that is to be written to the SQL database.

My question is, how do i go about allowing the user to upload the file, unzip it in the jsp page, and allow me to read the file? Thanks in advance!

1. Add an <input type="file"> and make your form have enctype="miltipart/form-data"
2. Use commons-fileupload to obtain the byte[] of the file (in a servlet of yours)
3. Use java.util.zip.* to extract the files. See here
4. Either parse the CVS (here) or if your database has an utility to import CSV, pass the files using Runtime.exec(..)
