Re: Compiled GWT JS size > handwritten JS size?

Thanks for the vote of confidence, Dal. In fairness, there are some cases
where you wouldn't use GWT, and writing a static Web page with NO Javascript
is certainly one of them. GWT is intended for rich Internet applications.

GWT incurs some overhead just to bring in the base JRE, so if all you need
is a few lines of Javascript, there's not a compelling case for GWT. But I
know of an app that started with a few lines and grew to 3000 lines of
script, at which point the developers wished they'd used GWT even for the
few lines.

Apps that benefit the most from GWT are those that could not conceivably be
written without it. One example that comes to mind is Sumwise, which
implements a complete financial modeling language and spreadsheet in the
browser. Large projects / teams also get the most from GWT due to the
improved manageability of a strongly typed language vs. a dynamic language.

Re: Compiled GWT JS size > handwritten JS size?

2011-03-15 Thread Gal Dolber

I have been working with gwt for more than 2 years now and I can't imagine a
page where I won't use gwt.

If you really try you may find some cases where handwritten js produce a
smaller page than gwt. It is also probable than in the small size of that
cases the difference won't matter. But I doubt you will get a better
performance from js than gwt.

Design of Breadcrumb Interaction

2011-03-15 Thread Jake Wharton

I have created a widget which allows for easy construction of the breadcrumb 
design pattern using common GWT patterns (including HasWidget) with relative 
ease. It is only when trying to wire this widget up to my MVP that I am 
running into issues.

While the breadcrumbs could be history based, my implementation is of 
pure hierarchical structure mapped to the logic of what the pages represent. 
A good example would be a vehicle inventory. The inventory has vehicle 
manufacturers, each manufacturer has models, and each model has pages for 
viewing specific info on a component.

Navigating into a more detailed view and adding the associated crumbs should 
be easy as you're only pushing items onto the stack via an event or 
injecting some kind of controller and calling a method.

The things I am uncertain of are:

   - If the user starts the application directly on viewing a car from a 
   bookmark, who is responsible for publishing the parent crumbs? Obviously 
   work has to be done to fetch information from the server about the names of 
   the parent crumbs.
   - Clicking a link which navigates "up" a crumb-level but to a different 
   car/manufacturer/whatever requires both removing the more detailed 
   breadcrumbs from the control and changing the current level to point to the 
   correct page. Should the whole trail be rebuilt on every place change?

My current line of thinking is for writing some kind of BreadcrumbController 
which would handle the (re)building of the crumbs and loading any 
information on parents. This would be a singleton injected with the place 
controller and request factory. I'd then inject this into each activity for 
the interaction.

Does anyone have any thoughts on this whether critiques on my thoughts, 
suggestions for a better solution, or perhaps a link to something with 
similar functionality?

Compiled GWT JS size > handwritten JS size?

2011-03-15 Thread ss.require

Let's take a common non very interactive page, like a common
"Wikipedia" page. For such pages, where there is not a lot of
javascript: Compiled GWT JS size > handwritten JS size and it's more
optimal(performance overhead) to use simple JavaScript than GWT

On the other hand, if web-page is very interactive, like Gmail, then :
Compiled GWT JS size < handwritten JS size due to GWT's optimizations.
In such cases it's more optimal(performance overhead) to use GWT than
JavaScript.

In general, It would be a mistake to use GWT for Wikipedia due to
performance overhead. Am i right?

The

Nothing to do with JSR 303 Bean Validation.

Can't help on the validation side though.

Re: Older version of GWT Eclipse plugin

2011-03-15 Thread KD

This is what I would do..
Install sdks in a separate directory say /gwt-sdks/2.0 , 2.1,
1.7 etc

In Eclipse under Preferences, just choose which one you want to be
active/default. Same goes for app engine
Now under project properties, chose the desired sdk in "Use Specific
SDK"

If you reference versioned gwt jars in your project, then you better
mavenize it if possible and change dependency as need be

Re: GWT application requires Plugin to be installed in browser

Hi BhaskerT, welcome to GWT.

Ben is correct. GWT development mode allows you to develop and debug quickly
in the browser without having to do a full compile to JavaScript. If you
haven't tried it already, be sure to try Debug As | Web Application and set
a breakpoint in your app in Eclipse, then tickle it in the browser. When
you're ready to publish your app, click the Compile button in Eclipse to
create the war folder.

FYI, Gmail was written before GWT and hasn't yet been rewritten. Many other
Google apps use GWT, including the AdWords and AdSense admin consoles, parts
of Docs and Maps, the new Groups interface, Google Moderator, and coming
soon, Blogger, which I tweeted yesterday from @googledevtools.

You are running your application in development mode, which means you
are probably running it from your IDE.  Its used for debugging and fun
stuff like that.

If you compile and deploy your web application to a server, like
Apache or Tomcat, you wont get that.

GWT application requires Plugin to be installed in browser

2011-03-15 Thread BhaskerT

Hi All,

I am new to GWT(2.0) development.
Problem statement: While accessing a GWT based web application, IE ask
me to install GWT plugin.

Solution: If i instal the plugin then it works perfectly fine.

As per my knowledge Gmail is based on GWT. and if i try to access
gmail from any where it does not ask me to install any plugin.

I want my application to behave in similar manner.

What i have googled till now is, there is something called GWT
development mode, due to which this problem is caused.

Any suggestion will be very helpful.

Thanks.

page. On start and on end jsp I have a GWT EntryPoint and I checks
that the onModuleLoad method is called.
I tryed to add these html tags to my jsp:




but I always saw the old page. I tryed to submit FormPanel on taget
"_blank" and it works (the browser shows me the new page).

Someone, can help me?

How to compile selectively or avoid compilation of inheriting/implementing classes?

2011-03-15 Thread KD

Here is my situation.

On the top level of my API is...

com.mycompany.core.MODEL

I have made this a GWT module, has a blank entry point and has
MyModel.xml. Its structure is as below...


  
  
  
  
  
  
  
  


Now there are implementations of this model to make a default out of
the box framework and those reside in the following packages

com.mycompany.core.API
com.mycompany.core.KERNAL

i.e. Abstract and concrete classes in these 2 packages above implement
interfaces from the MODEL package
e.g
AbstractMessageListner (in core.API) implements MessageListener (in
core.MODEL)

Now there is another GWT module...

com.mycompany.DASHBOARD

which inherits the MODEL

When I compile all in eclipse or do a 'mvn clean install', there are
no errors. There are Maven dependencies in Dashboard for MODEL source

When I launch dashboard module from eclipse using my custom .launch
file, I get a lot of "No source code..." found errors pointing to
classes in API and KERNAL and also things like

- No source code is available for type java.io.ByteArrayOutputStream;
did you forget to inherit a required module?
- The method close() is undefined for the type OutputStream
- No...for type com.thoughtworks.xstream.io.StreamException; did
you...
- No...for type java.io.Writer; did you...

So my question is:
How can I avoid API and KERNEL being pulled in while compiling. My
argument is MODEL does not depend on anything, rather everything
depends on MODEL. Is there a way I can tell GWT compiler (preferably
selectively) not to worry about classes that DEPEND ON core.MODEL with
the exception of DASHBOARD of course.

My end goal is that, I would like to use MODEL in DASHBOARD on client
side and avoid writing new DTO interfacing between widgets and
backend.

Any ideas or help here would be super in taking me over this roadblock.

EditorDriver.setViolations in 2.3 release branch doesn't work as expected

2011-03-15 Thread Marcin Misiewicz

Hi

Lately I have a problem with calling isChanged on RequestContext here is the 
link to discussion on that topic 
https://groups.google.com/d/topic/google-web-toolkit/HznAkg94WUc/discussion

Thomas has suggested that my problems can be solved by using 
editorDriver.isDirty introduced in gwt 2.3. Today I compiled gwt from 2.3 
release branch and editorDriver.isDirty works as expected, but 
unfortunately 
setting violations on the editorDriver does not result of showing of the 
error messages in the view.
The view is quite straightforward and it consists a bunch of 
ValueBoxEditorDecorator instances and one embedded address editor. 

After some debugging, I guess the problem lies in the line 112 of the 
com.google.gwt.editor.client.impl.SimpleViolation#pushViolations.

  /**
   * Maps an abstract representation of a violation into the appropriate
   * EditorDelegate.
   */
  public static void pushViolations(Iterable violations,
  EditorDriver driver, KeyMethod keyMethod) {
DelegateMap delegateMap = DelegateMap.of(driver, keyMethod);

// For each violation
for (SimpleViolation error : violations) {
*  Object key = error.getKey();*
  List> delegateList = 
delegateMap.get(key);
  if (delegateList != null) {

// For each delegate editing some record...
for (AbstractEditorDelegate baseDelegate : delegateList) {

Calling error.getKey() always returns null, for every violation object in 
the collection and then delegateMap returns null for the null key.

Am I right, or maybe in 2.3 passing the validation error should be done in 
different way ?

I run the DynaTableRF example and in that app validation messages around 
textboxes are not displayed as well.

Also, I'm confused, what kind of errors are recorded by the editorDriver 
during flushing. 
In DynaTableRF checking for errors after flush results in one error related 
to the zipCode field (so suprisingly it looks like client side validation ? 
).
But in my example it simply doesn't work, althought I also have the embeded 
Address ValueProxy with the zipCode member annotated by @Pattern.

Re: Server Side ColumnSorting with AsyncDataProvider

2011-03-15 Thread John LaBanca

You can call CellTable#getColumn(int) to get the Column object from the
index.  Then you can use a Map of Column to ServerColumnId to resolve the
value to send to the server.

Spring Security 3.0 authentication problem

2011-03-15 Thread julio

Hi,

I have a GWT client that communicates with a Spring/SpringSecurity 3.0
server via REST/JSON.
Both run on the same tomcat/jetty perfectly, but I have a problem
introducing the authentication:
If I "POST" the server with an external HTTP client the url:

http://localhost:8080/myserverapp/j_spring_security_check?j_username=julio&j_password=mypass

the server response is OK (200)

but when GWT client tries the same, the status code returned is 0.
This is the code I'm using at the moment:

final StringBuilder content = new StringBuilder();
content.append("j_username=" + URL.encode("julio"));
content.append("&j_password=" + URL.encode("mypass"));

final RequestBuilder builder = new
RequestBuilder(RequestBuilder.POST, URL.encode(BASEURL + "/
j_spring_security_check"));
builder.setHeader("Content-Type", "application/x-www-form-
urlencoded");

try {
builder.sendRequest(content.toString(), new
RequestCallback() {

public void onResponseReceived(Request request, 
Response response)
{
Window.alert("STATUS : " + 
response.getStatusCode()); // returns
0 ??
}

public void onError(Request request, Throwable 
exception) {
Window.alert("ERROR");
}

});
} catch (final RequestException e) {
Window.alert(e.getLocalizedMessage());
}

why does it return 0? any idea?

Thanks,
Julio

Re: image gallery with celltable or celllist

2011-03-15 Thread Albert Lacambra

I find a cellList ok. The problem come with key navigation. With celllist I
think you can just us Up and Down arrows and when you use a float or
inline-block pressing up and down you move to right or left. The cell table
doesn't resolve the problem because it works with rows.

The other think I don't really understand is why to use a cell with image. I
would just build a cell per image.

Server Side ColumnSorting with AsyncDataProvider

2011-03-15 Thread Stephan T

I'm trying to implement server side sorting using CellTable and
AsyncDataProvider in GWT 2.2. I've followed the example in the
documentation and have everything working with the AsyncDataProvider
only fetching ten objects at a time. But when it comes to sorting I
can't make it work.

I can't figure out how to tell the server on which of the objects
attributes to sort the query result. In the onRangeChanged-method I
can get the ColumnSortList and then get the columns. But the column
object does not contain information like the columns headerString.

If I could get the columns headerString I could figure out which
attribute of the object to do the sorting on, but I can't and now I'm
out of ideas.

I could of course subclass the column-object and add some kind of
identifier-method to it, but I have a feeling that it's something I've
missed because it shouldn't be that tedious.

Re: Code splitting like Facebook

2011-03-15 Thread ss.require

MVP framework is a top-level gwt framework that uses all standard gwt
features. In particular, it uses standard "code splitting" feature. I
can split my code in  the same way as MVP does, but my initial problem
still remains. I don't see any advantages of using MVP. Maybe, you
mean something else or you have not understand my problem!

Re: Need Help for gwt-rpc mysql database connectivity

Yeah, I've been meaning to do something like that in my application.
The current lack of details on the client isn't very pleasant for
users or developers.  SSH-ing into the prod server is annoying as
well.  I'm always worried about breaking something with a twitchy rm -

I'm still curious as to why OP can't see the logs in his server,
though.  If it happens in development mode, odds are the server

Manage dependent GWT projects with Eclipse

2011-03-15 Thread Samuru Jackson

Hi,

I have a project that contains certain common stuff which is defined as a
GWT module.

I want to included that commons project into several other independent GWT
projects.

At design time there is no problem adding the commons project as a
dependency. However, running jetty from Eclipse fails.

The only simple solution that I'm aware of is to link the source folders
from commons into the sub-projects.

Is there any alternative to that?

Thanks

Re: Get value of GWT property at runtime

2011-03-15 Thread Paul Robinson


Possibly not as simple as you wanted, but you can do something like this:
(1) Create base class com.foo.ThemeInfo and subclasses ThemeInfoOne and 
ThemeInfoTwo
(2) Add this to your gwt.xml:










(3) In your client-side code:
  ThemeInfo info = GWT.create(ThemeInfo.class);

and you'll get an instance of ThemeInfoOne when using theme1 and ThemeInfoTwo 
when using theme2 and an instance of the ThemeInfo base class otherwise

This should let you do what you want, and also move the "if using theme#1" test 
to compile time.

There's no need to merge, because when you do a working copy, you're locking 
the public version. The idea of a working copy is that you work in private, 
and the public version stays the same until you "publish" your work.

Re: How can I put Hyperlinks inside a CellTable, which behave the same as the Hyperlink widget?

2011-03-15 Thread John LaBanca

If you want to allow both clicks and new tab clicks, try this:

Render an anchor tag with the history token as the href:
Click Me

In your Cell, catch the click event and do the following:

   - If shift or ctrl is pressed, ignore the event.  The user is opening a
   new window.
   - If the right button was pressed, ignore the event.  The user will see
   the context menu.
   - If the left button was pressed, call Event.preventDefault() to prevent
   the page reload in IE, then call History.newItem("myToken").

Jetty in development/production

2011-03-15 Thread Jens

I know it is a GWT group but as GWT uses embedded Jetty I hope someone with 
a deeper Jetty knowledge is reading my questions and willing to answer :)

We currently use Glassfish 3.1 with the following features:
- EJB 3.1 Lite (only local no-interface beans, mainly for using @EJB)
- @ManagedBean on some classes to be able to use @EJB inside
- JPA 2.x (Eclipselink)
- JAX-RS 1.1
- Servlet 3.0
- Session Failover / Clustering
- Connection pooling and validation
- maybe in the future: web sockets / push

Our server code is pretty stateless and with some rewrite I guess we could 
get rid of @ManagedBean classes and maybe also of EJBs as we only use them 
for easy @EJB injection (could be done with google guice also).

Is it possible to integrate these features into Jetty? Do you think this 
will result in some performance increase (and memory reduce)? Does anyone 
use GWT + Jetty in production or even has compared Jetty + J2EE features 
with Glassfish? If its possible to integrate all of these features, how 
robust is session failover / clustering?
Could we also configure the embedded jetty used by GWT Eclipse Plugin to 
match our production settings (J2EE features + same application context root 
+ hot redeploy)?

Thanks in advance.

This is more for Ben then the original poster, but you can make your own

Code splitting like Facebook

2011-03-15 Thread ss.require

Hi!
I need to create a web-application with the design like Facebook. So I
want to have a single gwt-module for the entire app and use "code
splitting" feature for dynamic loading of all needed pages. But there
is some problem:

>From main page(when the module is already loaded) a user can navigate
to any page of my app. The total amount of pages will be very
huge(Let's say 1000). If I use "code splitting" feature I must to
place the next code-fragment 1000 times in my module:
GWT.runAsync(new RunAsyncCallback() {
@Override
public void onSuccess() {
new 
SomePagelet().load();
}

@Override
public void onFailure(Throwable 
reason) {
}
});
Thus my single module will be a large size and the loading time will
be very long as well. I want to find a way to say gwt what a pagelet
to download in runtime! Now I see an only possible solution: 1)analyze
compiled js scripts 2) then, extract the piece of the script that
handles loading of the exclusive fragment 3)On the server I add
extracted piece with specified pagelet-name to be downloaded to the
output html.

But this approach is hard. Does anybody have similar problems? Any
useful advices would be very appreciated!

Is there a way to detect the debug mode inside the code ?

2011-03-15 Thread oarguim...@labocom.com

Hello.

I'm new to GWT development and I want to detect if the GWT application
is in debug mode/session (i'm using Eclipse plugin), i have to do this
because in Debug mode many POST and GET have different locations
(cross site using a proxy in apache) than Release mode.

Actually I use a constant property in my project but it's easy to
forget and if another developer compile my GWT application it WILL be
forgotten...

Here is an example of my code to explain why i need to detect this :


String GetUrlPost(String Url)
{
String res = GWT.getModuleBaseURL()+Url;
if (constants.modeDebug())
res = constants.adresseServeurPost() + "/proxyredir/" + 
Url;
res = URL.encode(res);
return(res);
}


Where adresseServeurPost is the IP of apache.

I want to do a thing like :

if (isDebugMode())
...
else
...

Ok a cloned proxy would be a solution. But I still need a queue or something 
in case the real non-cloned proxy isn't saved yet but the next auto save 
occures. So in general RF forces me to wait for the response. But its ok.. 
as I have to wait anyways because of the entity version (either by waiting 
for the response or by increasing auto save intervals).
And you are right, in case of constraint violations one should lock the form 
and the entity during save. But in our aggressive auto save strategy we 
would like to not lock the form and display any constraint violations in a 
non intrusive way. In most cases the user will correct these violations 
anyways because most violations will occur because of "unlucky" auto saves 
(e.g. data not completely and thus maybe incorrect edited be the user).

Uhh..so if I work on my private copy for 2 weeks and then unlock it to 
update the public copy, a second user can destroy my work by unlocking his 
copy a day later and thus overwriting my 2 weeks of work? :) Having working 
copies is a nice idea but merging them back into one public copy seems 
tricky. But of course it depends on the application.
