hi! consider doing both - javascript may be turned off by the user in the browser. if turned on, all required fields will return filled out correctly. if some values are missing, you know that javascript has been turned off and can handle the checks on the server side. in that case you will normaly know the names of the required fields anyway - but in order to make your code portable, consider the previously posted tip to use standardized names for the required fields (by adding a prefix or suffix like "req_" or "_req" or the like...) so the servlet may be used for any HTML-form. greets
