Can you use HTML5? If so, then why not
use com.google.gwt.storage.client.Storage? For example in my newer apps, if
the login is successful and a checkbox is set, the app remembers the target
server and username:
// set/clear local storage
final Storage storage = Storage.getLocalStorageIfSupported();
if (storage != null) {
if (view.getRememberId().getValue()) {
storage.setItem("o_username", user);
storage.setItem("o_server", server);
view.getRememberId().setValue(true);
}
else {
storage.setItem("o_username", "");
storage.setItem("o_server", "");
view.getRememberId().setValue(false);
}
}
The next time the user calls up the app, I check local storage for these
values:
// Fetch fields from storage.
final Storage storage = Storage.getLocalStorageIfSupported();
if (storage != null) {
String user = storage.getItem("o_username");
view.getUsername().setText(user);
view.getServer().setText(storage.getItem("o_server"));
if (user != null && !user.isEmpty()) {
view.getRememberId().setValue(true);
}
}
I don't store the password, but I could.
This is a lot less painful than my older approach of injecting HTML
(similar to yours) and it's consistent across HTML browsers, include mobile
devices using MGWT.
