Re: how to log messages in ABCServiceImpl
Hi Fahad!
As soon as want to log something in the serverside, you may need to
use a regular serverside logging.
There are several different libs which do help with this.
Jetty could use SLF4J as an impl one, so you could use
org.slf4j.Logger. (see http://www.slf4j.org/manual.html for samples)
For more details, look into here -
http://docs.codehaus.org/display/JETTY/Debugging

Re: Intercepting all gwt rpc calls on gwt (browser) side.
Sorry. Think I did not make the whole problem well-understood. I need to intercept the thing not in the serverside, but in client side! E.g. I can not import javax.servlet.filter - it is a part of Servlet API which lives in Servlet container, and I need to get info about RPC calls in GWT part - the one which is js-compiled and executed in browsing. Any more thoughts?

Intercepting all gwt rpc calls on gwt (browser) side.
Is this ever possible? My case is pretty simple - I want to detect when was the last call made to have the 'session expiration' kind of functionality. For this I wanted to have all the calls to the server intercepted and scheduled the timer for session lifetime each time. Once the timer fires (it is the same moment as server session dies) I could transfer the user to sessionExpiredPage. What do you think - is it possible at all? Maybe, there is much easier way of doing the same, but i missed it? Thank you all. Alex. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT JSNI : How to access a div
Hi Sumved.
If I'm not mistaken, GWT module gets loaded to an iframe on the page;
that's why jsni code can not locate the div.
Simply saying, 'document' is for an iframe document, and 'window'
points to that specific iframe window object.
In order to access hostpage structure you should use $doc and $wnd
respectively - they hold 'document' and 'window' of the host page,
respectively.

Re: Best ways to avoid unwelcome CSS cascade side effects?
>From what I got here, GWT styling style :) means that you do not
heavily use 'global' CSS selectors; most of the styling work is done
with classes.
we're working on large application, and only 'global' styles we use
are related to quirks, not to styling.
I'm using some more complex selectors as:
.widget-class td {
color: black;
}
but only for widgets internal structure of which I know and own. Just
to make styling easier.

Re: seo and google web toolkit
That's true; I was also thinking of redirect. Also, this is good for non-js browsers. Links users would see it OK, which is really valuable for me. Although, does not google ban for ? This sounds pretty much like a doorway page. I'm really interested in how searchers treat this. In official release what's they say about cloacking: " So what's an honest web designer to do? The only hard and fast rule is to show Googlebot the exact same thing as your users. If you don't, your site risks appearing suspicious to our search algorithms. This simple rule covers a lot of cases including cloaking, JavaScript redirects, hidden text, and doorway pages. And our engineers have gathered a few more practical suggestions: " (taken from http://googlewebmastercentral.blogspot.com/2007/07/best-uses-of-flash.html, though it's old) Unclear moment for me is that what do they mean saying 'exact same thing as your users.

Bot may think that you're blindly redirecting the user to strange page with the only 1 javascript file inclusion and no content at all. Maybe, something new has happened which allows more SEO methodics and i missed this? Thanks for the point with redirect, Alex.

Re: Openlayers Gwt
Hello. I think, elements inside openlayers have their own cursor style. You could create transparent topmost div (as lightbox, but transparent) and show it with cursor: wait. This would do better, because would block all the other events from being sent to the underlying widgets.

Re: Translate localised messages in GWT app
It's not that hard to make dynamic translations loading, and make them working (almost) the same way as google static i18n. We adandoned google static i18n because of compile time - we have huge app, and having 6 languages * 5 browsers = 30 different bundles was killer shot. This can be achieved with Generators - you need to create JSON-like file with all strings, then load in to the client, then (through JSNI) give access to these loaded strings. That's all. However, this way of doing things has some drawbacks as well: 1. Each client does 2nd request for translation. So, we have 2-step GWT bootstrap and then 1 more asyncRequest for the constants loading. 2. This is additional work noone wants to do for free :) On Sep 9, 3:18 pm, mars1412 wrote: > > After some research I'm thinking maybe we should use the gwt dynamic > > translations (somewhat like you mention mars1412), but this implies > > that all language strings of the application should be transferred all > > at once and then will be stored as a javascript variable on the > > client.

Re: seo and google web toolkit
I think they would never execute your code (even in javascript) on their crawlers :) electricity costs more. As for htmlUnit and google adSense - no prob with that; I believe, you could easily leave adsense blocks as externals even in HTMLUnit output. Or find other solution which would do this. Problem in having static content and enriching it with gwt is that you'll need to create application for each page (if they are different) and app creation in GWT is fairly overheaded. Also, you'll need to have gwt app bootstrap on each page load, which is no good.

Re: Polygons using GWT
actually, there are different Canvas widgets avaiable now.

Re: Translate localised messages in GWT app
Hi. Did I understand you correct that you want to create a tool to easily translate apps? Like this user story: 1. User logs into the app. 2. All the strings which are not translated are red. 3. They are clickable. 4. Once clicked - user is presented editbox to enter text to 5. once entered - value is saved in code in properties file and editbox disappears. 6. On the next compilation, these strings are included to the compil If this is what you meant - no, I have not ever heard of such an intelligent tool. If someone knows something about such tool, I'm interested also. Alex.

Re: seo and google web toolkit
I am not expert, though i have some recommendations. 1. Don't even try to generate _really_ different content for searchbot and for the end-user. Sometimes googles sends request with 'normal' user-agent, and if you have different content for users and bots, you'll be banned (because of cloacking :) ) Though, there are some ways to do so, Though, not sure /me has enough time to work with google customer support to clear this issue (if they have customer support, have never heard of it:) ) 2. You may try create normal static application with unique URS, and just wrap some page elements with javascript to provide rich functionality. UIBinder is of new stuff. 3. You may try searhcing here (in this group) for such problems. People resolve it in different ways. I've heard of interesting way - generating html content by HTMLUnit and feeding it to the bot. Simply - if your application sees it is a bot, it runs gwt (javascript) code in headless browser on the serverside, and flushes momental DOM snapshot to the response. 4. Look here - http://lexaux.blogspot.com/2009/03/afraid-of-being-banned-by-google-for.html I was going to make a little demo some time ago, but had no time to complete it :( sorry. Though, there may still be some interesting facts.

Re: permission issue?
You can only communicate to server from which the javascript was
downloaded.
There is a way of mixing different services, but from what I've seen
they mainly mean that you need to load some javascript from each of
the servers into specific iframe, and then make these javascripts
communicate throgh top window.

Re: Good practice: setting style before adding it to a panel!
In more or less big project I'd rather create set of widgets, which do
not need addition of the external styles.
So, all styles are applied in constructor.
And then - you just create widget, and add it to a panel.

Re: GWTCanvas and IE...
IE does not support canvas well. You may use wrapper libraries, which
dispatch output to canvas if possible, and for IE try to emulate it
with VML.
Here's blog posting about this:
http://lexaux.blogspot.com/2009/08/gwt-canvas-widget-drawing-in-browser.html
You can select among several libraries; make sure you create some
prototypes before making a decision.
I succeeded with GWT-Widgets canvas proof of concept widget.

Re: onMouseOut not always caught
I had same problems - mouseOut events were missing in IE. I believe, these are not GWT problems, browser does not simply produce appropriate event. I then had to implement EventPreviewer, and listen to all mouseMove events (well, it was performance-satisfactory). On each get of mouseMove event i was checking if target element is the one I'm listening to, and if not, treated this as mouseOut. Several tips: * Start eventPreviewer only when you get mouseOver event from your icon. This would save some ticks. * If you're waiting for mouseOut of complex element, beware not to forget to check the element as DOM.isOrHasChild(el, mouseOutEl) * be sure to disable event preview once you got synthetic mouseOut. This would help save ticks as well.

Re: Performance issues in GWT application
You might have setup redirect on your domain name management console. If so, all requests are being sent to the zoneedit first, and then their disaptcher sends them to your internet IP. Just open up shell/cmd and write ping myserver.com If you see your IP, this is OK, need to figure out other problems. I bet you'll see other IP - one from zoneedit. If ip is different this means that you need to setup DNS records. I'm not sure what management panel you use; but goal is to change A- records of the DNS to point to your IP.

Re: Problems with Async Calls
need more info. Try going to the published rpc endpoints with browser and see if they're published. Check logs of the web container. Try to add logging to the client code; log events to Firebug console, for example. And check the configuration again - your webapp is configured, working fine, clean in logs, server is accessible, etc. Also, make sure that you have not hardcoded entry-point locations in the client code.

Re: Create own widget
You'd rather use Composite then subclassing panels.
It would look like
public class MyClass extends Composit {
private VerticalPanel panel = new VerticalPanel();
public MyClass() {
initWidget(panel); // really important, this makes panel
underlying wdgt of composite
}
In this case you get 'clear' class, without all the superclass
methods.
You don't want users of your widget to manipulate it contents - it's
widget and it should be opaque. So, exposing add/remove methods is
bad.

your image in java2d, makes all necessary operations, etc. If there
are any parameters of image generation, transfer them to the servlet
as query-parameters (http://myservlet?a=110&b=123&c=aaasdfWEasdfa)
2. Set output content-type of the servlet to the appropriate image
format (resp.setContentType("image/png")
3. Flush the image body (encoded to corresponding format) to the
servlet's output stream
All you need then to get image on the client-side is to issue
something like this:
image.setUrl("http://myservlet?a=112&g=assa";);
Refer here for the details of the Image class:
http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/Image.html

Re: Performance issues in GWT application
Your request needs to go through too long chain, that's why it is slow. I'm not sure what's the purpose of the proxy server. Does it do any valuable work, or anything it does is just forwarding requests back and force between internet clients and your JBoss? Also, why do you need Apache on the local machine? You could just change JBoss configuration to listen to default port eighty, thus eliminating one more item from chain. What I'd recommend is to get some domain name. 3rd level names can be optained pretty easily. And then setup DNS to point this name to your jboss static ip address. In this case clients will have direct requests, except the first time when dns request would precede loaded one.

Re: How to set Font style for full application
Simply, style entries from the class (.gwt-label, for example) are
more important for the html renderer than element-related one.
So, what you could do is to replace style declarations from the
public.css with your own.
Also, if you're specifying fonts, be sure not to forget about fallback
ones. So, if you'd like to make a style with Times font, you should
see something similar to following:
.gwt-Label {
font-family: Times, arial, sans-serif;
}
if the client's system does not have Times font installed, it would
use arial, if no arial - any of the sans-serif fonts.

Re: Adding the same widget more than once
Basically, you could use Command pattern to tie out the widgets from
command actions.
[example] So, there are 4 different widgets (2 links, a button and a
key listener) that trigger the same action .
This may be a good practice.
