Thanks for this nice article. would be great if you could answer my question as well I have been in Java swing development for few years and now I see GWT getting popular , though I haven't used GWT , what are differences between GWT and Swing and how much learning curve for a swing developer to learn GWT.

Thanks

Hi when I am trying to deploy the greetMVP example in my process server I am getting with Multiple Servlet injectors detected. This is a warning indicating that you have more than one GuiceFilter running in your web application. Can you help me out in this.

Hi. Thanks for the tutorial - a great effort. I downloaded the complete project as a zip (as suggested in the article) - it compiled, but the RPC failed. The error message was "Application out of date ... expecting version 6, got 5 ...". Turned out I just had to replace gwt-servlet.jar (2009) with the latest version (2011).

Thanks for the information http://extreme-java.blogspot.com

HI Thanks for your tutorial. It works as miracle. Though i had a small question. How do we change the call from /greetmvp/dispatch to anything that we want like /greetmvp/checkthis and how do we call this???

Thanks again.

@Chris,

Any progress on the solution you are working on to get rid of the fudge factor?

I've worked with Sencha Ext GWT (a.k.a GXT) a lot over the last 9 months or so.

It's a rich library and can be adapted to fit in with MVP but it can take some work. For instance, at a basic level you'll need to make components adhere to HasValue interfaces and so on. Those sorts of changes are pretty quick. More advanced components like trees, grids and combos need more effort.

All in all, we've got some very impressive results using this library.

Cheers,

C.

Awesome! My manager says we can put a link to here in our license header and give you props. You probably saved me a week of work.

Would you by any chance have any recommendations on widget libraries? Some of them have some cool features we could really use, but seem to force you into the MVC pattern.

Even if this is old, it still looks like a great guide to get started!

Question: I don't see any license restrictions on any of this code. Have you released this into the public domain?

Hi,

You might like to take a look at gwt-platform (http://code.google.com/p/gwt-platform/ and http://uptick.com.au/content/getting-started-gwt-platform).

2010-10-02T13:07:32.761+01:00

Jared,

Sorry to hear that you had trouble getting this code working. I'll try to post a link to an updated snapshot based on the latest releases of the gwt-presenter/gwt-dispatch libraries. Is that the update you are referring to? If you let me know your particular pain points then I'll try to address them.

As with many blog posts, what was written above was correct (to the best of my knowledge) at the time of writing and, indeed, a year is a relatively long time with a project evolving as rapidly as GWT. In fact GWT 2.1 will provide its own MVP library potentially removing the need for gwt-presenter. It seems harsh to call me on the fact that the code is now out of date - that's just life in the technical blogsphere.

When I use the term "best practice", it is not self proclaimed but taken from a Google I/O 2009 talk which discusses a best practice approach to developing GWT projects which crucially means employing MVP, Command and Dependency Injection patterns. I believe this post successfully demonstrates the setup and interoperation of the required libraries to use the patterns.

Regards,

Chris.

2010-09-30T06:26:57.516+01:00

yea um, this article is almost too old to be worth using.
Wish OP would submit some updates for 2010...

I've managed to integrate gwt-presenter & dispatch, as well as work up a decent smart-gwt interface. Once I get it rock solid, I'll post it here by some means.

I feel compelled to share it, after working an entire day getting old code from 2009 to work.
I doubt that the above article even repesents an accurate "standards of practice" anyway. GWT has changed alot.

Now I know why Java's logo is a coffee cup..
it's the same as other things early in the morning that you hate to deal with, but do so anyway cause your cracked out on caffeine and lusted for money.

2010-09-16T13:38:32.025+01:00

Hi,

Great job. Do you think that you can post an integration with Spring framework on the backend ? It seems that i can use Sping MVC or Spring4gwt (not supported cause Google Gin), Google Gin, GWT-SL, ... There is also Spring Roo (I didn't have a look at it).

Thanks

Hi,
Do you check http://code.google.com/p/guit/ ?
I think Guit have the same structure with this example.
So sorry, I'm a new comer. I don't understand a lot of thing. Please help me.

Hi,

First thanks for this excellent tutorial! This incredibly helps to jump start.

It looks like the code is no longer compatible with the 2.04 GWT environment as I get the following ERROR which breaks the app.

Using SDK 2.0.4, Eclips (latest) and Java 1.6 on OSX

It starts with a warning:
14:56:04.924 [WARN] [greetmvp] Line 41: Referencing deprecated class 'com.google.gwt.user.client.rpc.SerializableException'

[INFO] Calling doSend
[ERROR] Handle Failure:

14:56:30.248 [ERROR] [greetmvp] 2010-07-24 14:56:30,247 [ERROR] Handle Failure:
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException: Type 'co.uk.hivedevelopment.greet.shared.rpc.SendGreeting' was not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a custom field serializer. For security purposes, this type will not be deserialized.

Now to fix this weired error, remove the gwt-sevelet.jar from the WEB-INF/lib dir and things will work again.

Hello

Thanks for a great guide.

I have a problem with the changing of presenters/views.

I have a LoginPresenter/LoginView when i login i want to change the presenter/view to StartPresenter/StartView.

Where and how should i do this?

Thanks again

2010-05-27T10:16:58.581+01:00

@Chris: Yeah, that's clear. I wanted to know, where the GreetingResponsePresenter will be triggerd. But I believe, that I have found the point: It's because of the

bindPresenter(GreetingResponsePresenter.class, GreetingResponsePresenter.Display.class, GreetingResponseView.class);

in GreetingClientModule, right?

Thanks for your answer.

2010-05-26T23:31:14.047+01:00

@seakey

Nothing too clever I'm afraid. GreetingResponsePresenter defines this:

@Override
protected void onBind() {
...

eventBus.addHandler(GreetingSentEvent.TYPE, new GreetingSentEventHandler() {

@Override
public void onGreetingSent(final GreetingSentEvent event) {
...
display.getDialogBox().show();
}
});
}

Obviously it's the call to .show() that causes the display of the dialog box. The code block is a handler for a GreetingSentEvent which is fired when a server call returns successfully:

public class GreetingPresenter extends WidgetPresenter {
...

private void doSend() {
...
dispatcher.execute(new SendGreeting(display.getName().getValue()), new DisplayCallback(display) {

...
@Override
protected void handleSuccess(final SendGreetingResult result) {
// take the result from the server and notify client interested components
eventBus.fireEvent(new GreetingSentEvent(result.getName(), result.getMessage()));

}

});
}
