gwt - Is it possible to save state of Web application -


i build web application using gwt (and/or smartgwt) uses number of forms collect data. possible save progress user can leave application , when comes continues data (s)he has entered?

if yes, have use database?

of course.

one of way use gwt 's rpc framework make calls java servlets . not need database store form data can store form data inside httpsession object provided java servlets . can imagine httpsession has built-in data store allows store number of key/value pairs , each client has own httpsession.

you can refer followings links/ tutorials basic ideas .
