How to read Data From Excel File Using servlets,jsp

Requirements:
1) Read data from Excel File : Suppose the File contains: Empnumber, Empname, and Salary columuns.. There will be thousands of rows.

-> we have to read data from Excel file and validate the data( i.e, the Empnumber must be varchar, Empname must be character, and Salary must be numeric).
-> if the data is valid then store the data in the database table1.

-> if the data is not valid then find out the location of the invalid data with index number and the column which is invalid and store the invalid data with index number in a database table2.

This can be done using servlets,jsp,javascript

Expecting a reply soon from all of you guys.. I will be thankful to all of you if you give me a solution..

There is nothing in servlets or JSP that will help you read the Excel file. That is the domain of other tools.

You would use servlets and JSP to upload a file from a client system, but the actual reading of the file is independent of whether it's in a web app, a Swing app or even a command line application.

As such, I've moved this to the Other Open Source forum, where tools such as POI are discussed.

The two most popular packages to read Excel files are POI and jExcelApi. You can find links to them on the AccessingFileFormats wiki page.
