Re: More than one module
This is just a suggestion off the top of my head and may or may not
work as i think it will.
To address your case I would setup 1 Module for the entry point and
use it to choose which of the other Module's to load for the main
page. I think this should allow you to take the most advantage of code
splitting so as not to load any of the data for one page when the
other is chosen.
Something like...
// PageChooserEntryPoint.onModuleLoad()
if(loadPageOne) {
GWT.runAsync(new AsyncCallback() {
(new PageOneEntryPoint).onModuleLoad();
});
} else {
GWT.runAsync(new AsyncCallback() {
(new PageTwoEntryPoint).onModuleLoad();
});
}
Im not sure if thats the best way to go about it, but its the first
thing that came to mind.

Re: Passing PHP variables to my GWT application
You might want to take a look at this:
http://code.google.com/webtoolkit/doc/latest/tutorial/JSON.html
Although the examples there are using a servlet for the server-side,
that is not a requirement. The server simply needs to be accessible at
the requested URL and output the formatted JSON.
The basic idea is to make a request to the server and have the server
send back the json data structure. You can then eval, or use a js json
parser, and setup Overlay types so you get to use the objects like
regular java objects.

Re: what large apps use GWT?
You can find out if a page is gwt with this http://gwt-instrumental.googlecode.com/svn-history/r5/latest/index.html Drag the box into a bookmark and when your on a page, activate that bookmark and it will give you info about the page. If it shows no widgets, then its not GWT.. Not that it is foolproof or anything...

Re: Million access to GWT Appl ??
Your essentially asking the wrong question. I think its better to think of by how much will GWT or products similar to GWT reduce the load on a server. You have to consider the fact that every user accessing a traditional website backed by a templating engine involves alot of resources for each and every request for new information. Take a web forum for example. I think they are probably one of the least effecient communication mediums and would be very interesting to see a GWT implementation of one. With the status quo web forum you have full page loads happening every single time a user wants to move around on the forum. And if the user wants to see what is new on the forum... you guessed it, full page load. Now, if you consider all the ways that having most of the web forum on the client side and using much more lightweight RPC calls to get new info (and ONLY new info) there would be quite large improvements. I wouldnt be suprised if the resource requirement of a GWT based web forum dropped the load on even the most highly active forums by upwards of 80%, and probably more if you really took the care to setup some proper caching. But regardless of how the server resource load would drop, just the bandwidth drop alone would be a 100% win. 2010/6/21 Jaroslav Záruba : > On Mon, Jun 21, 2010 at 9:28 PM, rakesh wagh wrote: >> >> If you compare gwt to other js based toolkits, they all behave similar >> as far as client to server communication is concerned. gwt only makes >> life simple for the developers. > > ...and (with comparably complex UI) makes your JavaScript run faster :) >> >> Rakesh Wagh >> >> On Jun 19, 7:44 pm, manish kumar wrote: >> > Hi, i have gone through many articles on web and found that GWT is not >> > good for an application that has million users access simultaniouly. >> > Is that really true?

Re: MVP Framework in GWT 2.1 M1 ?
The one half of Expenses isnt even MVP. The one you access via Expenses.html is a hard-wired app. That is the one they were showing at Google I/O. The other part, the Scaffold app I believe is what Roo spits out found under Scaffold.html. I'm not sure as to just how much of that has been hand tweaked and how much is straight up codegen. Of course, all of that stuff is still under heavy development.

Re: Does a private variable in Java stays private when compiled to javascript?
There is a GWT module you can include that might make life a bit

Re: Theory behind UiBinder that makes TabLayoutPanel work
I'm only just starting to dive into GWT internals but I believe to do this you will need to create a Parser for your widget to be recognized internally by UiBinder. http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/uibinder/elementparsers/TabLayoutPanelParser.java The method error your getting is from the fact that GWT is magically trying to map the attribute which it has failed to deal with in any meaningful way to a method in your class which of course doesn't exist. You'll notice within that parser that barHeight and barUnit are being consumed by the parser. And of course the rest of the parser is about dealing with the child tags that it supports as special.

Re: Devmode vs prod performance
In devmode you are running within a JVM, production is running from the browsers javascript engine.

Re: Best way to Deserialize JSON String to Java Object
Essentially that's about it. Although you probably want to put them
into a different package. The default Eclipse GWT Project contains a
'shared' package that is for this purpose. Its also by default in your
[project].gwt.xml file with the tag .
Adding those source tags to your gwt.xml file tells GWT that those
classes need to be available client side. Hence why you wont find the
'server' package in that file, as it's server side code only. By
accessing a class in shared from the server side code, it will get
compiled and be available for you.
The rest is all done for you when GWT creates the MyServiceAsync class
which you define the interface for, and within the
RemoteServiceServlet which your Servlet extends.
I think it would be a worthwhile experiment to see if and how much of
a difference there is between using GWT-RPC and using JSON with
Overlay Types.
Just to throw another option into the mix you could roll your own RPC
interface using GWT Generators like GWT does.
While we're on the subject of GWT-RPC, are you locked into using a
Servlet on the server side? Is there some binary format that GWT
converts to for serialization, or is it simply producing a JSON string
and decoding it in RemoteServiceServlet.

Re: Best way to Deserialize JSON String to Java Object
All good points, but I think you guys are totally missing the point.
He was taking a POJO and converting it to JSON for transmission using
GWT-RPC, which is completely redundant since GWT-RPC can simply send
the POJO and handle all the messy bits for him.
Simple is better...

Re: Best way to Deserialize JSON String to Java Object
Shouldn't have a problem sending a HashMap back and forth. As far as i
can tell GWT has a fairly complete implementation of the Java
Collections API, and all of which are Serializable, so there shouldn't
be any issues. I haven't used it for much more than Lists so there
might be quirks I haven't come across yet.

Re: Best way to Deserialize JSON String to Java Object
Is there a particular reason that you _need_ the JSON string? If your using GWT RPC then you can simply send a Java Object to the server and the underlying GWT will handle the serialization for you. If you the JSON string is coming from somewhere else and you really have no choice, then it may be worthwhile to put together a JSO Overlay, use the Overlay to instantiate a POJO on the client side code, and send the POJO to the server via GWT RPC. Since your new some of that probably makes no sense, and If you can give a little more detail as to why you need to have JSON originating from the client I'm sure this can be explained a bit better to fit your case.

Re: AsyncCallback - returning values to enclosing block
What you want to do is have some method in the caller that is waiting for the result that the callback can call once the data is retrieved. So you would make the getUser() method return type void and, if the class defining that method is the same as the one calling that method, add another method handleUser(String s) which will be called from within onSuccess.
