We have a excel file stored as blob in the database. The user requested to
display in the web browser and they can do basic editing for the excel
document, such as change the cell, deleting or adding rows, and save the
modified excel to the server side. Is that possible to use GWT to program

Unless you're wanting to send it down to the client and get the
contents using the File API or similar, just parse it on the server
using POI or jExcelAPI and send it to the client via a request and
display it in a grid/table on the client. Then after they're done
editing it, send their changes to
Thanks, Kevin. I am new to GWT. My another question is how easy that
will be in GWT to edit the grid/table? Does GWT provide API to do
that? When I tried a small program the cell in the table of GWT is not

I'm not sure if GWT directly has that or not. Looking at their
examples, I'd guess not. I use GXT because of their more complete
widget set. If that's too large a library for your uses, you'd just
have to listen for clicks and put an editor (i.e. a form widget) over
the grid cell.
As for having
Hi,
Yes it is possible. At first you must open your excel file with a
library (e.g Apache POI) on the server side and then send excel file
data to your GWT application , after changing data , GWT application
send changes to the server and then you must persist this change with
your library (e.g Apa
