Java EE (Java Enterprise Edition) General Discussion

I am currently writing a small application in JSP, and need something like a Excel grid to enter data, I would do text fields but that would take too long to enter the data into.

Do datagrids allow me to enter data? Or are they just used to display data? I have search the web and only found a few examples on how to display data but nothing where I enter data into a db using a datagrid.

If someone could point me in the right direction I would really appreciate it.

Thanks
