Not sure, but I believe Excel reads csv (comma-separated value) files. You would have to print to a text file with commas separating the values, and make sure you import into an Excel workbook with the same format.

Put a botton on the JSP page that causes the servlet (or another one) to generate a the data in a .csv file.

Or some other format that Excel likes. But csv is the easiest to do

Put the data in a text file (comma-separated value) then open the file with Excel, this is the easy way.
You can also call a servlet, iterate the list where you have the data and use the POI library (http://jakarta.apache.org/poi/), to bring the data in a file excel.
Another way is to use the library DisplayTag in your jsp, this is a tag that display the data in a table, give it a list of objects and it will handle column display, sorting, paging, cropping, grouping, exporting, smart linking and decoration of a table in a customizable XHTML style. Take a look to this url

Assuming the user has excel or some other spreadsheet installed on your desktop you can set your servlet response as the following and the page will automatically be loaded into excel.

 
Something must be done about this. Let's start by reading this tiny ad:
