Where can i put the images
Hi All,
As i m new to the GWT, i dont know where to put the images for my
site.
com.test.gwt.contactus.client is my package structure of my client and
contactus.java has the following code:
Image jimmyFull = new Image(bold.jpg);
final PopupPanel imagePopup = new PopupPanel(true);
imagePopup.setAnimationEnabled(true);
imagePopup.ensureDebugId(cwBasicPopup-imagePopup);
imagePopup.setWidget(jimmyFull);
jimmyFull.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
imagePopup.hide();
}
});
Basically where can i have the image, so that when i compile it should
go with my site.
Kindly guide me.Thanks :)
Cheers!!!
Mohan

Google Chrome Frame GWT
So here comes Google Chrome Frame. A brilliant idea and sorely needed by IE.(if you don't know what it is then: http://code.google.com/chrome/chromeframe/ ) Ok. So IE will be running content as if it was chrome based on a tag in the page. How do we deal with that? I am sure there are multiple strategies but someone has probably thought of some very smart way of doing this and I am too lazy to come up with one.

Best way to pass value to
My GWT app is embedded inside a tab view of a JSP page and I wanted to render the GWT module based on the content/context of the parent HTML. This requires passing initial value to the GWT app entry point and from there the GWT app can fetch values to server using RPC. I was able to do this using com.google.gwt.i18n.client.Dictionary approach. My question is, is this the best way to do it or is there better alternative/s?

FileUpload Service????
Hi,
The example below uses the FileUpload Class for sending a file to the
Server.
My question (being very new at this) where and how do I write my
Service (in this case form.setAction(/myFormHandler);).
If my question is clear.
Stephan
public class FormPanelExample implements EntryPoint {
public void onModuleLoad() {
// Create a FormPanel and point it at a service.
final FormPanel form = new FormPanel();
form.setAction(/myFormHandler);
// Because we're going to add a FileUpload widget, we'll need to
set the
// form to use the POST method, and multipart MIME encoding.
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);
// Create a panel to hold all of the form widgets.
VerticalPanel panel = new VerticalPanel();
form.setWidget(panel);
// Create a TextBox, giving it a name so that it will be
submitted.
final TextBox tb = new TextBox();
tb.setName(textBoxFormElement);
panel.add(tb);
// Create a ListBox, giving it a name and some values to be
associated with
// its options.
ListBox lb = new ListBox();
lb.setName(listBoxFormElement);
lb.addItem(foo, fooValue);
lb.addItem(bar, barValue);
lb.addItem(baz, bazValue);
panel.add(lb);
// Create a FileUpload widget.
FileUpload upload = new FileUpload();
upload.setName(uploadFormElement);
panel.add(upload);
// Add a 'submit' button.
panel.add(new Button(Submit, new ClickListener() {
public void onClick(Widget sender) {
form.submit();
}
}));
// Add an event handler to the form.
form.addFormHandler(new FormHandler() {
public void onSubmit(FormSubmitEvent event) {
// This event is fired just before the form is submitted. We
can take
// this opportunity to perform validation.
if (tb.getText().length() == 0) {
Window.alert(The text box must not be empty);
event.setCancelled(true);
}
}
public void onSubmitComplete(FormSubmitCompleteEvent event) {
// When the form submission is successfully completed, this
event is
// fired. Assuming the service returned a response of type
text/html,
// we can get the result text here (see the FormPanel
documentation for
// further explanation).
Window.alert(event.getResults());
}
});
RootPanel.get().add(form);
}
}

If you don't use ImageBundle, then either:
- you put them in your package's public subfolder (com/test/gwt/
contactus/public) and use new Image(GWT.getModuleBaseURL() +
bold.jpg);
- or put them in your war/ folder and use new Image
(GWT.getHostPageBaseURL() + bold.jpg)
You can of course use subfolders...
The advantage of the first approach is if your module is reusable
(inherit/ed in another module), you'll always have the images right
(that's how the GWT themes work for example).
The advantage of the second approach is that it's easy to change the
image being used: just change the image in the war/, or even have
multiple war folders each with a different bold.jpg in them. That's
generally how you'd do themed versions for, e.g., different clients
(e.g. the client's logo); provided it won't affect the app's layout.
And you wouldn't even have to compile the app for each and every
client: compile it once and just copy the generated code over and over
in your different war/ folders.

Re: Why Not Bypass The Middle Man
On 23 sep, 06:24, lusus l...@fishbytedesign.com wrote: First I would like to point out a few important facts: 1) I think that GWT is a fantastic idea, and that the developers deserve awards and ice cream and funny hats and should be carried through the streets. 2) I am just throwing this out as a discussion point. 3) I am not a classically trained programmer, and some of my terminology may be technically errant. Try to go with the overarching idea, and not just write me off because I thought REST meant nap time. Now with that said, here's my question/thought. Isn't it time that we finally quit trying to warp the WWW into what we really want it to be, and come up with a new protocol all together? More specifically, isn't it time we made a browser that simply interprets the major programming languages - not riding on the WWW, but with it's own network protocols? Just like any computer's native apps, just with the ease of deployment of web apps? Well, have a look at Java Web Start, .NET ClickOnce or Adobe AIR install badge. It could exist like a stub on an individual client computer, run over it's own public port, and allow push AND pull communication. Something like Opera Unite? Programmers would need only to learn the proper communication methods, and could then write unbridled applications that are served directly to the clients, bypassing the rube-goldberg system of manipulation required to make it understandable by the CURRENT browsers. What if you could write a JAVA program where main() was served to the client browser and that's that. As cool as GWT is, when you step back and think about the actual structure, it's conjures (at least for me) images of popsicle sticks and duct tape. First you write the JAVA code, and add CSS styles. Those are combined and interpreted to Javascript which is optimized to several (currently used) browsers, which is in turn interpreted to HTML and displayed in the browser, which is based on a protocol that does not REALLY allow push communication. *** Again, nothing against the GWT developers. They did a fine job of contorting the existing structures to bring us closer to the goal. *** That'd be a Java applet, or a Java desktop app served with Java Web Start. I realize that, as far as cloud computing is concerned, the GWT outcome is (almost) the same as what I'm talking about. You write JAVA code, and it gets displayed in the browsers. Who cares what torture it has to go through to get there. right? Looking back, it was oh so simple to get virtually everyone using the WWW. Would it be that hard to get the general public to accept a new internet that involves application browsers? Yes! And finally, the browsers could be made to understand multiple programming languages. It could basically be an omni- (and slightly upgraded for communication purposes) Virtual Machine. Who would you do it? using a plug-in for each language? how would it be different from Flash, Silverlight or Java applets? Here is my list of key points: 1) Cut out the middle man. No more Rube-Goldberg. 2) Allow Push communication. Have a look at server-sent events in HTML5 and the WebSockets protocol and API. 3) No worries about upgraded or new browsers, and cross-browser compatibility. (The App-Browsers would just keep up with the current programming language upgrades.) Why do you think we're all dealing with x-browser compat? because people don't upgrade their browsers; so why would it be different? 4) Use the layout tools that belong the the program language you are using. 5) Wouldn't it possibly even be more secure? (maybe not) No, why would it be? 6) Let the kids play in the WWW kiddy pool. Let the real programmers swim in the deep end, away from the yellow water.

Re: Why Not Bypass The Middle Man
Hi lusus, I'm not a a guru in all web technologies, but I think knowing enough to comment on this. On Sep 23, 12:24 am, lusus l...@fishbytedesign.com wrote: First I would like to point out a few important facts: 1) I think that GWT is a fantastic idea, and that the developers deserve awards and ice cream and funny hats and should be carried through the streets. 2) I am just throwing this out as a discussion point. 3) I am not a classically trained programmer, and some of my terminology may be technically errant. Try to go with the overarching idea, and not just write me off because I thought REST meant nap time. Now with that said, here's my question/thought. Isn't it time that we finally quit trying to warp the WWW into what we really want it to be, and come up with a new protocol all together? More specifically, isn't it time we made a browser that simply interprets the major programming languages - not riding on the WWW, but with it's own network protocols? What do you mean by major programming languages? Javascript is a major programming language. (more on this below) I understand, however, that HTTP was originally created to display content (documents) in standardized way, as BBS were insufficient, and there was a need to, well, please the user and make it more attractive and user friendly. Hypertext markup language (HTML) was born to satisfy the problem, and it is still a proof of concept design even today with web applications. XSLT tried to change that and allow custom markups, and all, but my opinion is, why changing something that works and is general enough to support nearly any kind of data representation? On the same thought, I believe that the language is not faulty, but the renderers that interprets it... It could exist like a stub on an individual client computer, run over it's own public port, and allow push AND pull communication. Programmers would need only to learn the proper communication methods, and could then write unbridled applications that are served directly to the clients, bypassing the rube-goldberg system of manipulation required to make it understandable by the CURRENT browsers. What if you could write a JAVA program where main() was served to the client browser and that's that. As cool as GWT is, when you step back and think about the actual structure, it's conjures (at least for me) images of popsicle sticks and duct tape. First you write the JAVA code, and add CSS styles. Those are combined and interpreted to Javascript which is optimized to several (currently used) browsers, which is in turn interpreted to HTML and displayed in the browser, which is based on a protocol that does not REALLY allow push communication. *** Again, nothing against the GWT developers. They did a fine job of contorting the existing structures to bring us closer to the goal. *** Push communication is evil as it allows servers to send data to the client, and I certainly don't want to end up on a web page having data uploaded to me without my consent, or knowing about it. What about push techniques? you might say, well, at least we see a Loading... message while the page push is being made. Furthermore, the amount of work to simply allow this, supposing it's really implemented, and to keep track of all users connected to the web page is too great for the trouble. I mean, we're not talking about enterprise applications only here, but world wide web applications. How could a busy web server keep track of all the thousands users, if not millions, connected to it's content and knowing when it's no longer necessary to send data? The overall process would simply slow the server down. Except keeping track of session data between calls and have a garbage collection system to cleanup all this on inactive data is quit enough trouble already. On the other hand, you can actually use third party software (ie. Java) to do this; Applets may keep a socket open in TCP to the origin and receive push from it, if you really need to. GWT actually solves a big issue for many big project; a standardized way to communicate to the server(s) throughout the whole application. And even re-use the system in all projects. I personally consider text/ XML/JSON responses as legacy, and RPC as the new way of communicating with the server side part of the application. There are still improvements to be made, about protocol and especially on the software layer design patterns, but the general idea is there, and it works. There are actually existing projects being developped to allow GWT and PHP to communicate through RPC, and the idea is sound and looks promissing. This means that it won't matter what language your servers can support; your GWT application will be able to communicate using RPCs with PHP, Java, etc. in a seamless fashion. I realize that, as far as cloud computing is concerned, the GWT outcome is (almost) the same as what I'm talking about. You write JAVA code, and it

Hi
myFormHandler would be your server side class name.
in your xml file you would write something like this

/servlet
servlet-mapping
servlet-namemyFormHandler/servlet-name

So every time you submit your form it would go to that server mapping.
Something along those lines.

Refresh content of Dictionary object
Hi,
is there some way to dynamically refresh/change the content of the
Dictionary i18n object?
I currently have a script src=lang.js/script that provides for
the content of my dictionary.
This works fine, but now the lang.js content has changed (through some
actions).
Unfortunately, the changes are not reflected in my Dictionary.
I tried this too:
Element e = DOM.getElementById(MSGS_JS_TAG_NAME);
if(e != null) {
DOM.removeChild(RootPanel.get().getElement(), e);
}
e = DOM.createElement(script);
DOM.setElementProperty(e, language, JavaScript);
DOM.setElementProperty(e, src, url);
DOM.setElementProperty(e, id, MSGS_JS_TAG_NAME);
DOM.appendChild(RootPanel.get().getElement(), e);
But still the values I get from Dictionary are not the same as those
in the JS, until I eventually refresh the page.
Is there a way I can do this without refreshing?
Thanks,
Steven

Re: Why Not Bypass The Middle Man
Would it be that hard to get the general public to accept a new internet that involves application browsers? I think that you dramatically underestimate people’s reluctance to install something new. It took a long time for the web and its protocols to reach the levels of saturation that they currently have. Trying to create a brand new one would just about be an exercise in futility. But about GWT specifically... think about it like this. GWT is the evolution of web development. It does what computer languages and development technologies have always done. They took a look at what was needed Javascript, CSS, html, Ajax and they encapsulated it allowing the developer to compose solutions to their specific needs without (or with little) regard for the underlying complexities. Compare that what a high level language like C or Fortran are. They allow you to compose solutions to your problems in relatively easy to manage functions. You don’t care what it takes in assembly language to get user input from a keyboard you just create an input stream. This level of encapsulation is what GWT brings to the table for the web and in my opinion it is simply brilliant in its execution. I’ve been doing web and app development professionally for over 12 years now and I can’t remember the last time I was this excited about a new technology. I find that being able to compose web UI’s with a rich programming language to be liberating. Now that I’ve gone completely off track, to address your concern more directly: what would a new protocol mean for me as a developer? If all it provides is a way for me to execute Java (or some other high level language) on the client then for one thing it’s not really giving me anything fundamentally new. Especially if the UI Widget set was still based on Swing or AWT or the like. What it really does is limits where my app can be used because no one (or very few people) will have the ability to connect to it. The inherent ability to push from the server is pretty trivial in comparison to not having an app that can be used by the majority of people without requiring them to install new software and potentially modify firewall or other hardware settings. I mean, I’d rather just fake push by polling the server and have it usable to everyone. Ajax makes that trivial. And GWT makes Ajax trivial.

To put it simply: no; because Dictionary hasn't been designed for this

...but you can use JSNI and/or JavaScriptObject (overlays) instead of
Dictionary with the same result and more flexibility.

Why do we need to then convert that code to javascript, and then to html to then be interpreted by any number of different browsers. It's a long walk to get a short distance. Push communication is evil as it allows servers to send data to the client, and I certainly don't want to end up on a web page having data uploaded to me without my consent, or knowing about it. What about push techniques? you might say, well, at least we see a Loading... message while the page push is being made. Furthermore, the amount of work to simply allow this, supposing it's really implemented, and to keep track of all users connected to the web page is too great for the trouble. I mean, we're not talking about enterprise applications only here, but world wide web applications. How could a busy web server keep track of all the thousands users, if not millions, connected to it's content and knowing when it's no longer necessary to send data? The overall process would simply slow the server down. Except keeping track of session data between calls and have a garbage collection system to cleanup all this on inactive data is quit enough trouble already. On the other hand, you can actually use third party software (ie. Java) to do this; Applets may keep a socket open in TCP to the origin and receive push from it, if you really need to. I think I can safely say that push is NOT evil. Not in itself. Perhaps there are evil things that can be done with it, but push is actually very useful for number of purposes. It is absolutely possible/ plausible. We are talking about rich applications not just banner ads. And yes, sockets can be used, but that brings up my point about ports. (see my other responses). GWT actually solves a big issue for many big project; a standardized way to communicate to the server(s) throughout the whole application. And even re-use the system in all projects. I personally consider text/ XML/JSON responses as legacy, and RPC as the new way of communicating with the server side part of the application. There are still improvements to be made, about protocol and especially on the software layer design patterns, but the general idea is there, and it works. There are actually existing projects being developped to allow GWT and PHP to communicate through RPC, and the idea is sound and looks promissing. This means that it won't matter what language your servers can support; your GWT application will be able to communicate using RPCs with PHP, Java, etc. in a seamless fashion. Again, and I can't say it enough, I think that GWT is great, and a huge step in the right direction. I think that GWT points directly to what we have been slowly moving toward since the beginning of the WWW - the idea of serving real and robust applications. I think that, instead of continuing to contort the web, and stack new technologies on top of it, perhaps we should look at the idea of a new internet that takes into account the technologies and discovered needs that didn't exist when the web was originally created. Many optimizations have been made on the engines that runs Javascripts. The language itself has evolved and tends to have a more rebust structure (http://en.wikipedia.org/wiki/JavaScript. see versions table). The problem is that there is not a general consensus on this and browsers may implement the specification they want. It will take time, a very long time, but I believe that eventually we'll get to a point where Javascript will be as fast as Java. (Same with CSS.) I personally do not like the idea of a browser natively supporting many languages, as it is hard enough for all browsers to all support one single up-to-date language. Javascript is a great language for client side programming. There is this idea laying around for many years now, that a server and client might execute and communicate both sides with
Re: Why Not Bypass The Middle Man
Would it be that hard to get the general public to accept a new internet that involves application browsers? I think that you dramatically underestimate people’s reluctance to install something new. It took a long time for the web and its protocols to reach the levels of saturation that they currently have. Trying to create a brand new one would just about be an exercise in futility. But about GWT specifically... think about it like this. GWT is the evolution of web development. It does what computer languages and development technologies have always done. They took a look at what was needed Javascript, CSS, html, Ajax and they encapsulated it allowing the developer to compose solutions to their specific needs without (or with little) regard for the underlying complexities. Compare that what a high level language like C or Fortran are. They allow you to compose solutions to your problems in relatively easy to manage functions. You don’t care what it takes in assembly language to get user input from a keyboard you just create an input stream. This level of encapsulation is what GWT brings to the table for the web and in my opinion it is simply brilliant in its execution. I’ve been doing web and app development professionally for over 12 years now and I can’t remember the last time I was this excited about a new technology. I find that being able to compose web UI’s with a rich programming language to be liberating. Now that I’ve gone completely off track, to address your concern more directly: what would a new protocol mean for me as a developer? If all it provides is a way for me to execute Java (or some other high level language) on the client then for one thing it’s not really giving me anything fundamentally new. Especially if the UI Widget set was still based on Swing or AWT or the like. What it really does is limits where my app can be used because no one (or very few people) will have the ability to connect to it. The inherent ability to push from the server is pretty trivial in comparison to not having an app that can be used by the majority of people without requiring them to install new software and potentially modify firewall or other hardware settings. I mean, I’d rather just fake push by polling the server and have it usable to everyone. Ajax makes that trivial. And GWT makes Ajax trivial. Good input. And the funny thing is I agree with most of what you say. I definitely agree that GWT is the most exciting thing that has happened in the web world in a long long time. And yes, who cares what's under the hood (or in the cloud). But I still say two things: 1) even with GWT, you still have to rely on CSS, and therefore, deal with all the browser incompatibilities. 2) I still think that having push abilities would be a great step forward. oh, and I'm not saying it would be simple, but I believe that we could eventually get the world to accept a new browser (and network).

Re: A well-behaved, browser independent layout framework
Thanks for the pointer to LayoutPanel, at first glance it looks like it is trying to address some of this, so I'll certainly join in the discussion there! As for UiBinder, it really doesn't solve the problem, just punts it to...html. GWT solves most every problem in cross-browser compatibility, allowing the building of great coherent applications in browsers - except for a good layout framework. Relegating GWT to widgets sprinkled throughout a web of html, while a fine usage model, takes a step backwards and drops on many of the benefits of building a sophisticated, dynamic application in GWT. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT + mysql (noob questions)
I am writing a fairly large web app using GWT in Eclipse.My background is as a c++ desktop developer, so while I have used java before, sometimes I stumble on easy stuff. Anyway, I am currently attempting to implement a database to store data from my webapp. I am far from an expert in SQL, but I have done some desktop programming of SQL before, so I feel comfortable enough doing SELECTs and whatnot. (Most recently I did some development using the iPhone Sqlite stuff). Can someone point me to a good tutorial or something that gives an example of storing simple user data in a database from a GWT app? I found a servlet based java/mysql example, so I am concentrating on classes like datasource right now. I can only assume the SQL stuff needs to be contained on the server side of a GWT app anyway, so I was going to start there. But I had questions like: - what is the process for connecting to a database in hosted mode? Is just left to me to get something like MySql installed locally, and then follow instructions like listed here ( http://humblecode.blogspot.com/2009/05/gwt-16-using-jndi-datasource.html) in order to connect? - when I do deploy to a live webserver, is it just a matter of switching the database config (username/password, database name etc)? (as long as I have everything setup in mysql on my live webserver obviously) - how does 'Hibernate' fit into all this? I read about it, and see it mentioned everywhere.It looks like a library for persisting my java objects in the database, rather than pulling information out of my objects and storing the data only?

Eclipse client server separation
Hi all, GWT enables. among other things, the use of the same classes in client and server code. Client code is compiled to JavaScript and server code to Java byte- code. My problem is: If a GWT application is developed in one eclipse project - both client and server, client code can directly invoke server code and vice versa. The recommendation to help from making such a mistake is to use a package convention: - com.same.client for client code and - com.sample.server for server code This is not sufficient enough, for such mistake may still happen - especially when the eclipse adds imports automatically to the head of file in the imports section which is folded by default, causing you not to notice the package name. Also, there are classes that are shared by both the server and the client, like the Greetings interface(client uses and server implements). Where does it goes? I tried creating a working development environment with 3 projects: - Client - Server - Shared It was very complicated and needed a symbolic link from Shared to client - for the compilation to JavaScript. Does anyone feels the need as I am? Did anyone create such a hello world development environment?

Re: GWT + mysql (noob questions)
I dont have any tutorials at hand but your understanding of where the DB code lies is correct. It's totally on the server side and has nothing to do with GWT. Your GWT app would get access to the data via RPC. The RPC methods would in turn get data from the DB. Hibernate is an ORM (object relational mapper) which allows you to tie Classes to DB tables in a way that is largely transparent to your application. One problem though in using hibernate with GWT is that the classes created via hibernate cant be serialized to the client via RPC (not that i know of anyway) so a lot of people use different libraries to make clones of the faux-POJO's so that they can be serialized. (I do this in the project that i'm working on but i did it by hand) (um, POJO means plain old java object). If you're interested in using hibernate you should probably use it from the start because retrofitting the application after the fact would on undoubtedly be extremely painful. But with that said and with as much as i love hibernate if you're using all of these new technologies together for the first time you may become overwhelmed and hibernate is a fairly involved framework so you might be better off getting a good grip on GWT and GWT's RPC mechanism first. but as always, ymmv On Sep 23, 10:53 am, PJ Gray pj4...@gmail.com wrote: I am writing a fairly large web app using GWT in Eclipse.

Re: How can I have a function in my button call back, call a function in another class?????
Instead of defining the callback as an anonymous inner class you could
make it a regular class and pass an instance of the class containing
the method that updates your data into the constructor of the new
callback instance that you create before passing it to the RPC. Then
when the response comes back from the server you could simply call
it.
You could also call the method directly from the anonymous inner class
but there are some limitations as to what an anonymous inner class can
call from the outer class.
Side question, what is that 5 sec timeout for? You're not trying to
wait for the rpc to finish are you? That's bad voodoo. Async is not
your enemy.
Also, one other question what's with the 'onResponseReceived' why not
just use onSuccess?

Re: GWT + mysql (noob questions)
Thanks for the information. I feel fairly comfortable with GWT and GWT-RPC now. I implemented the command pattern MVP pattern as per Ray Ryans talk, for my communication over RPC. That gave me a pretty good crash course! I am sure there are details in there I'll be learning along the way though! As for Hibernate, I am just trying to decide if its something to invest time in now. Cause I really hate using technology just for whiz-bang/bandwagon reasons. It sounds like hibernate, when integrated into my app, allows me to avoid having to worry about the lower level SELECTs parsing results etcetc?

Re: Lost runtime exceptions when in hosted mode
If you client code has try catch blocks to catch the exceptions, then you can use the GWT logging framework and put the exception logging statements in the catch block. That'll log the exception into your server logs. Otherwise, I'm not sure if GWT provides the infrastructure to show exception stack trace on console because when the client code is running on browser as javascript there is no underlying console. May be the exceptions get translated into javascript errors.

Re: Why Not Bypass The Middle Man
Let me summarize: what you want is... Java applets, Silverlight, Flash/ Flex, with a way to do server push. Well, you already have all this: Silverlight can use sockets [1], as well as Flash/Flex [2] (I don't know for Java/JavaFX, but as far as I'm concerned java on the web is dead for a long time (except on the server side)). If you want some form of standard protocol to transport typed values, instead of plain old binary sockets, you can implement WebSockets (or any other protocol) on top of them. Thanks for adding to the discussion, but ... •As I have already said in several different ways, I know that there are solutions to the challenges I have mentioned. But as Célio pointed out, they are all kludges. We have constructed a huge Rube- Golberg machine to crack an egg. That's what originally started me thinking about this new browser idea. • Manipulating pull to simulate push is not the same as push. • Sockets/ports can be blocked. But as I said earlier, hardly anyone blocks port 80. If we had a standard port for serving application that allowed push communication, you wouldn't have to worry about it being blocked. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT + mysql (noob questions)
It sounds like hibernate, when integrated into my app, allows me to avoid having to worry about the lower level SELECTs parsing results etcetc? That is true for the most part but as Charlie said it's not a pure win because getting it to do what you want, how you want it to do it can be very tricky. I've been using it for oh, maybe a year and a half now and i still feel like i'm just getting my arms wrapped around it. I haven't really dug into IBATIS but it sounds like it may be an easier to use ORM. For me, the hibernate full text search is very valuable. It can be very fast but you really need to understand how it works to get it to do things right. The way the handle lazy instantiation often feels obtuse to me and i'm continually getting a better handle on it. There are a few books out on it if you're really interested as well as a lot of documentation online. If you do use it just never trust that it will query for data the way you expect it to. You have to stay on top of it or else it is very easy to cause situations where it will query repeatedly for data that you should be able to get with one round trip. On and BTW, i'm also a huge fan of the MVP pattern. I'm very glad that i saw Ray Ryan's presentation before i got to far into my project. He saved me from having to write a *lot* of boilerplate code. Are you also using Gin? I was reluctant at first because i was getting framework fatigue but it is pretty handy for being able to unittest your presenters.

It sounds like hibernate, when integrated into my app, allows me to avoid having to worry about the lower level SELECTs parsing results etcetc? All that code is handled by hibernate, so I can just make calls to classes for accessing/storing data and everything is persisted behind the scenes for me by hibernate? Is that correct? -pj On Wed, Sep 23, 2009 at 12:30 PM, Trevis trevistho...@gmail.com wrote: I dont have any tutorials at hand but your understanding of where the DB code lies is correct. It's totally on the server side and has nothing to do with GWT. Your GWT app would get access to the data via RPC. The RPC methods would in turn get data from the DB. Hibernate is an ORM (object relational mapper) which allows you to tie Classes to DB tables in a way that is largely transparent to your application. One problem though in using hibernate with GWT is that the classes created via hibernate cant be serialized to the client via RPC (not that i know of anyway) so a lot of people use different libraries to make clones of the faux-POJO's so that they can be serialized. (I do this in the project that i'm working on but i did it by hand) (um, POJO means plain old java object). If you're interested in using hibernate you should probably use it from the start because retrofitting the application after the fact would on undoubtedly be extremely painful. But with that said and with as much as i love hibernate if you're using all of these new technologies together for the first time you may become overwhelmed and hibernate is a fairly involved framework so you might be better off getting a good grip on GWT and GWT's RPC mechanism first. but as always, ymmv On Sep 23, 10:53 am, PJ Gray pj4...@gmail.com wrote: I am writing a fairly large web app using GWT in Eclipse.

Testing MVP Applications when using Overlay Types
Hello all, I've recently converted my GWT application to use MVP, specifically using the gwt-presenter project. I'm also using Overlay Types and RequestBuilder to talk to JSON-based services on the backend. Since Overlay Types use JSNI, it's not possible to do any JSON parsing in unit tests. The problem with not being able to do any JSON parsing is the callbacks will often call eventBus.fireEvent(GwtEvent) after the JSON parsing has happened. This means I can't fully test the flow of a presenter if event firing happens in a callback. I wrote up a detailed explanation of this issue on my blog[1]. Does anyone here have any suggestions on how I might go about solving this problem?

Config file for a user .
4. after saving it system tries to navigate to main page this does not
work with Internet explorer but works absolutely ok with Firefox 5.0
and in Hosted mode as well. this is the native code I am calling to go
to Main page
private native void reloadApp(String locale) /*-{
$doc.getElementById('locale').value=locale;

to be more specific in case of IE it is not making server call at all.
As per my understanding GWT takes care of Cross browser compatablity
issues as a Java devloper i dont have to bother abt this.
Please correct me if i am wrong.

Date-String, String-Date
I have a class called DateFormatter, which currently lives in both the
client and server directories, because I haven't found a way to do
what it does within a single file, or rather what I want it to do
within a single file.
Here's what the code looks like on the server side:
**
(package name removed)
import java.text.DateFormat;
public class DateFormatter {
private static final DateFormat dateFormatter =
new SimpleDateFormat(-MM-dd HH:mm:ss);
public static final Date timeToDate(String time) {
Date date = null;
try {
date = dateFormatter.parse(time);
} catch(ParseException e) {}
return date;
}
public static final String dateToTime(Date date) {
return dateFormatter.format(date);
}
}
**
...and here's the code on the client side:
**
package org.codingventures.blog.client;
import com.google.gwt.i18n.client.DateTimeFormat;
public class DateFormatter {
private static DateTimeFormat dateFormatter =
DateTimeFormat.getFormat(-MM-dd HH:mm:ss);
public static final Date timeToDate(String time) {
Date date = null;
try {
date = dateFormatter.parse(time);
} catch(IllegalArgumentException e) {}
return date;
}
public static final String dateToTime(Date date) {
return dateFormatter.format(date);
}
}
**
Currently this is breaking just about everything because the client
code won't run on the server and the server code won't run on the
client. This _wouldn't_ be an issue but because I have serializable
classes being sent across GWT's RPC which have to use one of these I'm
running into a lot of problems.
So, is there a way to combine these classes?

Re: Testing MVP Applications when using Overlay Types
Couldn't you do something like make the class that actually does the parsing be a dependency of the callback (ie passed in). Then create a mock version of that class that just returns whatever data (for verification)? This mock version wouldn't be based off the JSNI overlay abstract class, while your 'real' one was.Heck if you wanted, you could always implement the JSON parsing by hand for the mock class, without using the overlay.it is, after all, just a way of making parsing easier, correct? Then your testing could verify not only the flow of your app, but the JSON parsing as well. -pj On Wed, Sep 23, 2009 at 3:05 PM, Matt Raible m...@raibledesigns.com wrote: Hello all, I've recently converted my GWT application to use MVP, specifically using the gwt-presenter project.

You're not forced to use GWT-RPC Async-like (using AsyncCalback) interfaces, you can make your own callback interface if AsyncCallback doesn't fit your needs; but all in all, what I mean is that the JSON parsing should be hidden, an implementation detail of your service implementation. - make JSOModel an interface: that's part of my experiment too; except that I'm envisionning changing from a wrapper (similar to your BaseModel, but mine isn't generic and entirely implemented using JSNI methods) to a JSO overlay when I'll switch to GWT 2.0. Just that, because I actually never used GWT-RPC, I don't know how it works (or not) when arguments and return values are interfaces, so using AsyncCallback and GWT-RPC-like interfaces might not be a good choice after all (I even code the sync, RemoteService interface, to please the Google Plug-in for Eclipse; I haven't used it yet, but I thought about using dummy service servlets for some demo apps) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Serialization of Member Types
Hi all.
I am experiencing the dreaded was not serializable and has no
concrete serializable subtypes error in GWT... but... it's not the
typical issue... promise.
The class failing the 'IsSerializable' test is a member class inside
another IsSerializable class i.e. (using a dummy example):
public class Outer implements IsSerializable {
public class Inner implements IsSerializable {
public Inner(){}
}
private Inner myInner = new Inner();
public Outer() {}
}
Technically, in Java reflection terms, the Inner Class's constructor
has a single parameter, the instance of the Outer class that the Inner
is to be instantiated in. but, it is still a 'no-argument-
constructor' ... right?
If I change the Inner class to be declared as 'static' (public static
class Inner .) then RPC works fine.
My particular case is somewhat more complex, and the prospect of
having to externalize the inner class is messy... Am I missing
something about IsSerializable, or is it not possible to have an
IsSerializable Member Class?
Thanks in advance...

Re: Cookies and RPC
Hi Tom,
not sure I understand your cookie question, but in GWT you can query
for cookies using the class
com.google.gwt.user.client.Cookie
and there have a look at the method
/**
* Gets the cookie associated with the given name.
*
* @param name the name of the cookie to be retrieved
* @return the cookie's value, or codenull/code if the cookie
doesn't exist
*/
public static String getCookie(String name)
So in your GWT code you would check if a cookie exists like this
String cookie = Cookie.getCookie(myCookieName);
if(cookie != null){
// cookie exists
}

Inaccurate RPC Server-Client string transmission
Hi -- A strange thing. I'm creating a String on the server, and it's getting mangled by GWT RPC before it gets to the client (I think). I'm creating a 4 character String val1 = \0\0\u0032\u001b on the server and returning to the client within an IsSerializable class. I return the class as a function result to the client. The client sees the string as 3 characters: \0 \u0002 \u001b That is, the \0 \u0032 appears to be turned into \u0002 (yes, 2 characters turned into one)! I'm guessing that this is some weird Unicode processing, though I'm having trouble figuring it out. Does anyone know what's going on here?

Re: Best way to pass value to
Thanks for the reply. My GWT module is part of classic web
application embedded inside an html (generated using jsp). There are
certain parameters (string type) I'd like to pass a GWT module upon
initial load inside my page. So far, my solution is to use a
com.google.gwt.i18n.client.Dictionary. Is this the best way to pass
parameters to GWT module upon loading or there are better
alternatives?
e.g. in my JSP/XSL page
script type=text/javascript
var ID = {
identifier:xsl:value-of select=$path/@ID disable-output-
escaping=yes/
};
/script
and on the GWT module entry point:
Dictionary dic = null;
String ID = null;
try {
dic = Dictionary.getDictionary(ID);
ID = dic.get(identifier);
} catch (Exception e) {
Window.alert(No ID found!);
}
/* fetch some data based on the ID */
Thanks,
Dann

I'm not 100% sure i understand the question but it sounds like the
answer would be History. That's how you tell a GWT app to show a
specific page.

My GWT app is embedded inside a tab view of a JSP page and I wanted to
render the GWT module based on the content/context of the parent
HTML.
This requires passing initial value to the GWT app entry point and
from there the GWT app can fetch values to server using RPC. I was
able to do this using com.google.gwt.i18n.client.Dictionary
approach.
My question is, is this the best way to do it or is there better
alternative/s?

[gwt-contrib] Re: Adds parsers for Dock Stack layout panels. Updates Mail sample to use UiBinder.
Thanks, Isaac. If only it allowed us to have separate newline rules for
annotations on fields vs. methods. Unfortunately, turning off newlines for
annotations on members would have this unfortunate side-effect:
@Whatever @SomethingBig(blah) void foo() {
}
I'm not sure, but I think the cure might be worse than the disease...

Hey guys,
The autoformater will change this to
@UiField

which sucks. I want to fix that for annoations with no arguments, but
have no
idea how to. You have any clue to share?
Bugs the crap out of me too. I can't find any annotation-related
settings in the code formatter, unfortunately.
Just in case you didn't see this: in Eclipse 3.5 (I haven't looked at
earlier versions) there's an Annotations section on the New Lines tab.
That will let you remove the new lines after annotations, but it
doesn't let you decide based on whether or not the annotation has
arguments.

[gwt-contrib] Simple crawler
Reviewers: Dan Rice, Description: Could you review this patch for me? This simple crawler is intended to be used by users who crawl-enable their apps. It gives them an idea of what the crawler will see, without making any guarantees about emulating the real google crawler. It takes in either a sitemap file (get one from http://j15r.com:8800/Showcase/Sitemap.xml) or a URL (e.g., http://j15r.com:8800/Showcase). Optionally, it also takes an output file (by default, it prints to stdout).

[gwt-contrib] Conditionalize rich text area tests for HTML Unit, use the initialize event for delays
Reviewers: jlabanca, jgw, Message: I re-wrote some of the tests to use the new initialize event instead of a timer to wait for the area to become available. Htmlunit has some issue with FF3 emulation, so I filtered out the InitializeHandler out for Htmlunit. I also found a bug in the IE implementation in that the initialize event was called back before the cached HTML data was transferred over into the iframe.
