How to store a Excel document using Webdynpro

Hi Folks,

I need a Web application, where user will have an option of uploading an Excel file. Then the application should store this file in application server in Excel format.

Then I need another web application where, I will display a tabular structure with two date column and third column showing as a link to the file. Also this second application will have an option to save the file on desktop. I need a button to pass the data in this file to another program.

Technical issues:

I know how to read data from an excel by using Upload UI element. But how can I store the file on application server in excel format. And then how can I read the Excel file in such way that, I can show a link of this Excel file in a tabular structure displayed on a Webdynpro application.

Please provide your valuable inputs on this technical issue.

Regards

PG
