Re: Setting Up A Login Page To Use SSL
Nick, On Tuesday, May 24, 2011 11:56:57 PM UTC+2, Nick Apperley wrote: Max - With regards to point 1 I did consider it but it isn't feasible to use SSL for the entire website when large amounts of data is being sent to/from the server. Most of the data being received from the server is in JSON format, which although it is less verbose than XML it does include other pieces of data that hasn't been requested from the website (client). All of the received data comes from a DB as row(s). If a row contains a foreign key then the referred row (by the key) is automatically included instead of the key in a JSON file. This is automatically done by the server, no changes were made to do this. You can imagine just how much data is included if there is more than one foreign key, and this automatically scales up recursively if the included row also contains a foreign key. I'm sorry, but how is this an argument against TLS, again? Cheers! Max -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Please send some sample code in detail for Gwt server side method unit test cases.
Hi Rupesh, I don't think this has anything to do with GWT. Perhaps you'll have more luck asking the folks on the EasyMock mailing list at http://tech.groups.yahoo.com/group/easymock/ or read the Spring docs at http://www.springsource.org/documentation. You should consider posting some more code so that it's possible to understand your problem in detail.

Re: Setting Up A Login Page To Use SSL
Nick, two points: 1. Have you considered using TLS/SSL for your complete application? Without that a MITM would still be able to sniff the session cookie and act on behalf of the user, sniff users' data, modify data on the way between server and client and so on. 2. If you really really want to use TLS only for login purposes I recommend you redirect users to a simple login page using https and after logging in redirecting them back to the http version fo your app. HTH Max -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Prototypical implementation of Desktop Notifications
Hi,
(this is a re-post of my original posting to the GWT Contributors list. Due
to suspected lack of interest there I post it here now)
I'm a huge fan of Web Notifications (or Desktop Notifications as called by
Webkit/Chrome, see http://www.w3.org/TR/notifications/) so I started to hack
away a very rudimentary implementation of them in GWT. My implementation
consists basically of four components: A Notification class acting as a
wrapper around a NativeNotification class which extends JavaScriptObject.
For handling the display event (which is called show in the W3C spec) I
created a class DisplayEvent extending DomEventDisplayHandler.
For creating a Notification I borrowed the mechanism used in the
experimental Storage API of GWT 2.3:
final Notification popup = Notification.createIfSupported(, Title,
Body);
This creates a Notification object wrapping a NativeNotification object.
Since I'm not THAT firm with DOM events and stuff I would like you to
comment on my implementation and if it is somewhat usable or leaking memory
or sth.
The code is in prototype status and currently works in Chrome only.
Please find attached my implementation.
Cheers!
Max

Re: KeyPressEvent doesn't capture Enter
Hi julio, there's also an open issue in the issue tracker for GWT: http://code.google.com/p/google-web-toolkit/issues/detail?id=5558 It is increasingly annoying that the docs in http://code.google.com/webtoolkit/doc/latest/tutorial/manageevents.html are not updated to reflect this issue.

Re: textbox water mark
Hi pieceovcake,
yes, we're using sth. like you've mentioned a lot in our application. It
looks sth. like this:
...
private TextArea _ta;
...
_ta.setText(placeholder);
_ta.setStyleName(textarea-placeholder);
_ta.addFocusHandler(new FocusHandler() {
@Override
public void onFocus(final FocusEvent event) {
if (_isBlank) {
_ta.setText();
}
_ta.setStyleName(textarea-text);
_submitText.setVisible(true); // a submit button
}
});
_ta.addBlurHandler(new BlurHandler() {
@Override
public void onBlur(final BlurEvent event) {
if (ClientStringUtil.isBlank(_ta.getText().trim())) {
_isBlank = true;
} else {
_isBlank = false;
}
blurTextArea();
}
});
...
private void blurTextArea() {
if (_isBlank) {
_submitText.setVisible(false); // hide the submit button
_ta.setStyleName(textarea-placeholder);
_commentText.setText(placeholder);
}
}
We're using the _isBlank field to indicate that the user has typed sth. into
the text area and we don't replace this with the placeholder text if he
exists the area. But that's a matter of taste and requirements.
HTH
