Hi,

I am developing a web application using JSP/Servlet. I have a form in .jsp to upload excel file which is then processed (by servlet) and an excel ouput is generated. I need to validate input file to see if a certain cell in the workbook has some value as soon as user selects file (before hitting Submit). I don't want to use Javascript ActiveX control for validation since it only works with IE. Please suggest what's the best approach.

Thanks.
