Re: how to inherit external module jxl ? Problems working with excel sheets

Hi. Dalla. I am stuck with the same problem. Could you explain how you do it on the server side ?

Thank you.

You could do this using a file upload to the server,
do the excel work on the server side and then serialize the data and
send it back
to the client, displaying it in any way you want using GWT.
