Re: javax.persistence package
If you have complex objects that you need to map, you might need to write configuration files. To be honest, I don´t know what´s meant by complex objects, I don´t have any configuration files at all for my Dozer implementation, and it works like a charm, even when mapping nested objects. I have my DTOs on the client side aswell, by I´m not the one to answer your security question. Our application is only used inhouse.

I wonder what dozer gives me as an advantage - it seems it does not guarantee writing less config files? is it a security issue that we do not to put DTOs in client side in dozer project? Thanks, Tolga On Wed, Sep 2, 2009 at 4:54 PM, Dalla dalla_man...@hotmail.com wrote: Yes, exactly. This is pretty much it: DozerBeanMapper mapper = new DozerBeanMapper(); //This is a mapping from EJB to POJO //SimpleHeader is my POJO, purchaseOrderHeader is an instance of the corresponding EJB. SimpleHeader header = (SimpleHeader) mapper.map(purchaseOrderHeader, SimpleHeader.class); //Mapping from POJO back to EJB looks exactly the same //Here, Arrivals is the EJB, arrivaldata is an instance of the corresponding POJO Arrivals arrivals = (Arrivals) mapper.map(arrivaldata, Arrivals.class); So if you already have EJBs and want to use Dozer, all you have to do is basically make a copy of your EJB, remove all annotations and imports of javax.* packages, create a default no argument constructor, and make the new POJO implement IsSerializable.

GWT does not emulate javax.persistence.*, importing that package on the client side would cause errors when compiling. However you COULD use EJB3, if you keep the mappings in a separate file. But´s that´s not very flexible. I use EJB3 myself on the server side, and then use Dozer to convert the EJBs to POJOs before sending them to the client. Once the objects is sent back, you convert it back to an EJB, Works like a charm so far. On 2 Sep, 13:26, Tolga Özdemir tka...@gmail.com wrote: oh..it does mean we cannot use ejb3 yet.. right?

The GWT runtime ignores annotations --- they're not kept at runtime on the client. So you can pass annotated objects perfectly happily over the link and they'll work fine. I've had good experiences using Berkeley DB JE and GWT. It's possible to query an object on the server, have Berkeley DB instantiate it for me, and then just return it directly to the client for display. So I'd imagine you could use something similar with javax.persistence. The only thing you probably need to be concerned with is that if you instantiate an object on the server, pass it to the client, then pass it back to the server, you're getting a different physical object than the one you originally instantiated so the persistence layer might get its cacheing confused.

Re: Custom boot-strap / setting locale from request headers
On 2 sep, 23:50, mayop100 mayop...@gmail.com wrote: Hey Guys - There's a section on this page:http://code.google.com/webtoolkit/tutorials/1.6/i18n.html That suggests that there's an easy way to set the user's locale by parsing the Accept-Language header in the user's request. I want to have my GWT app always display the locale specified in the client's Accept-Language header - not the locale specified in the host page. I think I should be able to write a servlet to do this... and it sounds like this is possible based on that page, but I don't know enough about the bootstrap process to actually make this work. Has anyone else done this? To make it simple, we're using Apache's MultiViews with several copies (not copies actually, as we have some static HTML that needs to be translated): index.html.fr, index.html.en, etc. And each page loads the appropriate locale using a meta name=gwt:property content=locale=fr (see http://code.google.com/webtoolkit/doc/1.6/DevGuideI18nAndA11y.html#DevGuideSpecifyingLocale ) but you could achieve the same using some servlet or JSP as your host page, and generating the appropriate meta; there's something about it in the GWT Incubator IIRC: http://code.google.com/p/google-web-toolkit-incubator A more general question is - is there a way I could write a servlet that pulls the client's browser type and locale from the request headers and returns the appropriate GWT permutation? This would let me skip the entire Proj.nocache.js bootstrap process and speed up initialization. I feel like this shouldn't be too hard, but I don't really know what setup goes on in the nocache.js bootstrap file. Has anyone done this before? Can this be done? or is there essential setup that occurs in the bootstrap file? the *.nocache.js also loads the stylesheet and javascript dependencies, so it's a bit more than just selecting the appropriate permutation. Also, although you could determine the browser type on the server side, you would have to make a choice when it comes to IE8, as it could use either the ie6 or ie8 permutation depending on the documentMode. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Forwarding to TomCat
Hi All This may be entirely the wrong place to ask this question, but I'm hoping someone here has done something similar. If anyone objects to this I am more than prepared to desist. What I want to do is this: 1. Host Apache or IIS on an externally facing server and have it serve static things like images and (GWT) JavaScript. 2. have IIS/Apache forward requests for HTML pages (which are served up via Spring MVC on TomCat), RPC calls and webservice requests to TomCat on an internal machine (presumably through a firewall with the appropriate port open). This will give me a number of things: 1. Better security 2. Move the serving of the big stuff from TomCat to Apache/IIS Any help greatly appreciated. -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com b: paulgrenyer.blogspot.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How can I center arbitrary content on a fixed-size button?
I've got a tentative solution, but it's not quite the pure css
approach I was hoping for:
(1) Define GWT's html-face style as:
.html-face
{
display: table;
height: 100%;
margin: auto;
}
(2) Wrap the user's text inside:
html
div style=\display: table-cell; vertical-align: middle;\
user-defined-text
div
html
Is there a better/simpler approach that I'm missing?

In Java, AbstractButton.setVerticalAlignment(CENTER) just happens; you
don't have to think about it. But I can't seem to find any way to
achieve this same effect on a GWT Button.
Horizontal alignment is trivial: text-align: center. But I've spent
a couple of days trying increasingly bizarre strategies
(http://www.google.com/search?q=css+vertical+align) trying to achieve vertical
alignment, with no success to speak of.
Has anyone else struggled with this problem (or solved it)?

Re: ext-GWT vs GWT-ext

Um, ExtJS was underlying GWTExt - no? ExtJS went GPL - no? I guess if you are of a certain ideology then you prefer a BSD type license. Calling moves to the GPL dirty are flame bait I think.

Good practice: setting style before adding it to a panel!
He All, I would like to share the following good GWT programing practice (It just cost me to solve a tinny bug because of this): -- Set any style name/attribute just after a widget is created, before it's added to any panel!!! So do something like this: Widget wid = new HTML(test); wid.addStyleName(someStyleName); FlowPanel panel = new FlowPanel(); And NOT this: Widget wid = new HTML(test); FlowPanel panel = new FlowPanel(); // or some other panel wid.addStyleName(someStyleName); Wy? Suppose the panel is doing some sort of animation to add/insert the widget, like a slide/move, etc... animation. Then you could be in trouble in case the style name contains dimension information (width/ height) or other stuff that is used in your animation.. The dimensions that are retrieved by the animation that is contained in the flow panel will then be incorrect, as the style isn't set yet... This can lead to strange behavior depending on when the style is set, and what animation you use.. I may case it also was different in FF and IE.. In my case: I perform a slide in/out animation before the style name was set, such that the widget looked much bigger during the slide animation in IE (not FF) and all of a sudden turned to normal again after doing something else on the screen after the animation was complete. I put a little check in my animations now and check the style information that I need at the start and finish of the animation, as they should be the same, which wasn't in my case. So in general it's a good pratice to always set the style name/ attributes before adding your widget to any panel. Maybe you don't use animation, but you never know what will come in the future... And then al of a sudden you get these strange bugs after an upgrade of your own software or GWT. BTW: I noticed that the framework gwt-fx performs the slide animation in a deferred command, maybe for this reason --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

[ANNOUNCE] HtmlUnit 2.6, a headless java browser, released
A new release of the Open Source java GUI-Less browser is available, which allows high-level manipulation of web pages, such as filling forms, clicking links, accessing attributes and values of specific elements within the pages, you do not have to create lower-level requests of TCP/IP or HTTP, but just getPage(url), find a hyperlink, click() and you have all the HTML, JavaScript, and Ajax are automatically processed. The most common use of HtmlUnit is test automation of web pages (even with complex JavaScript libraries, like GWT and jQuery), but it can also be used for web scraping, or downloading website content. The main enhancements of this release: - Use cache for all kinds of (cacheable) content - Fix many issues with (de)serialization/li - Add a mechanism to save complete page along with images - Add support for Proxy Auto-Config - Better support for XHTML pages - And as usual, various bug fixes You can find more information in http://htmlunit.sourceforge.net/, the development team is looking forward to getting your feedback. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: gwt application does not run ie7
Without seeing the code, it's hard to tell. Personally, I'd level all the browsers and then see what you get.

Re: Good practice: setting style before adding it to a panel!
I can't see how creating a flowpanel between creating a widget and adding a style would make any difference whatsoever. Ian http://examples.roughian.com 2009/9/3 Ed post2edb...@hotmail.com He All, I would like to share the following good GWT programing practice (It just cost me to solve a tinny bug because of this): -- Set any style name/attribute just after a widget is created, before it's added to any panel!!! So do something like this: Widget wid = new HTML(test); wid.addStyleName(someStyleName); FlowPanel panel = new FlowPanel(); And NOT this: Widget wid = new HTML(test); FlowPanel panel = new FlowPanel(); // or some other panel wid.addStyleName(someStyleName); Wy? Suppose the panel is doing some sort of animation to add/insert the widget, like a slide/move, etc... animation. Then you could be in trouble in case the style name contains dimension information (width/ height) or other stuff that is used in your animation.. The dimensions that are retrieved by the animation that is contained in the flow panel will then be incorrect, as the style isn't set yet... This can lead to strange behavior depending on when the style is set, and what animation you use.. I may case it also was different in FF and IE.. In my case: I perform a slide in/out animation before the style name was set, such that the widget looked much bigger during the slide animation in IE (not FF) and all of a sudden turned to normal again after doing something else on the screen after the animation was complete. I put a little check in my animations now and check the style information that I need at the start and finish of the animation, as they should be the same, which wasn't in my case. So in general it's a good pratice to always set the style name/ attributes before adding your widget to any panel. Maybe you don't use animation, but you never know what will come in the future... And then al of a sudden you get these strange bugs after an upgrade of your own software or GWT. BTW: I noticed that the framework gwt-fx performs the slide animation in a deferred command, maybe for this reason --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: ext-GWT vs GWT-ext
Great, another clueless response. um, you are a *Ext* fanboy - no? There's a huge difference between a platform / app server / Java and a library being GPL. A library being GPL means you need you release the source of your entire application, simple. An app server or Java being GPL has absolutely no effect on the licensing and distribution of your application while using GPL library means that you need to release all your code making it unsuitable for use in commercial products. btw where did you read that Java bait and switched to GPL? We were considering using products from the Ext family a long time ago but avoid it like the plague now. Our legal team looked at it and found numerous violations and we did report in on the Ext / ExtGWT forums but the posts were mostly ignored or deleted. For example ExtGWT still uses some code from SWT. SWT is licensed under EPL and EPL is well documented to be incompatible with GPL. See http://en.wikipedia.org/wiki/Eclipse_Public_License Since we are no longer planning on using ExtGWT, I have no intentions of burning any more time trying to get them to resolve this. If you are going to make such statements or take a bait, do your homework first. To the original poster : we have decided to go with GWT and GWT incubator widgets and have had excellent results.

Re: rpc serialization problem
Are the List fields on your objects specified in terms of interfaces? GWT RPC needs to know as much about your objects at compile time, could you try using a concrete class instead - preferably ArrayList? It sounds like you're trying to serialize ORM objects directly, is that right? I don't know much about Data Nucleus and whether or not it dynamically enhances entity objects under its control with proxies etc. My experience is with Hibernate which usually does add something to a class, so serializing entities directly is strongly discouraged - either the entity objects have to be filtered of the Hibernate extras, or values copied into DTOs.

Re: GWT, MVP, and nested widgets
Ian,
Ok, I think I understand what are trying to do. Let me expand a bit on
the addMenuItem( Object i..); example in something a little less
abstract. First, I'm assuming your MenuItem is not equivalent to the
GWT MenuItem class, if it is the solution would be different. Note, I
don't have a full example so mileage may very. The approach is meant
to deal with MVP of list type interfaces, where the list items (i.e.,
MenuItem) bubble events up to a list presenter (i.e. MenuPanel).
The example assumes that instead of each MenuItem reporting
PlaceChange events, MenuItem selection events are bubbled from the UI
up to the MenuPanel presenter (through its view) and the MenuPanel
presenter fires the PlaceChange event. Effectively, a MenuItem's
display becomes a simple widget within MenuPanel's view and doesn't
require its own presenter (the presenter's work is handled by
MenuPanel's presenter).
First, some simple setup:
public class MenuPanel {
interface Display {
void addMenuItem( String label, String token );
HasSelectionHandlersString getMenuItemSelectionButton();
void clearMenuItems();
}
...
}
The above class shows a possible piece of the MenuPanel display
interface. I am assuming in the above that a MenuItem takes a label
that defines how the UI displays the object and the token as you
describe above for the associate place/location when the item is
clicked. In this example, the MenuPanel presenter determines the menu
items required for the current place and calls addMenuItem to tell the
MenuPanel view the MenuItem widgets to construct in the UI. The
clearMenuItem method can be used clear the MenuItems to rebuild the
specific items when the page changes. Notice that I included another
Display method called getMenuItemSelectionButton(), this returns an
object the MenuPanel presenter can add a handler to so it can detect a
MenuItem selection event. Here's an example of the bindDisplay method:
void bindDisplay( Display display ) {
this.display = display;
//Listen for a token selection when the user picks a MenuItem
display.getMenuItemSelectionButton().addSelectionHandler( new
SelectionHandlerString() {
public void onSelection( SelectionEventString event ) {
//Call MenuPanel private method to fire PlaceChangeEvent on
EventBus, selected item represents the Place token
doPlaceChange( new PlaceChangeEvent( event.getSelectedItem() );
});
...
}
With the above in place, the MenuPanel view becomes responsible for
translating the user input on MenuItems (such as a native Click
event) into a logical SelectionEvent
The above approach breaks down if the list items require a lot of data
to build or if the list items require additional logic beyond the
scope of the containing presenter. As I said in my previous post, this
approach also suffers from similar interface management problems as
DTOs.

I don't really understand how your addMenuItem( Object i ); method would
work.
I can't really have each view just create its own presenter (as a general
principle) as far as I can see. What I want to end up with is a menu item
which fires a PlaceChange event when it is clicked - for this it needs a
token, for example GWT/Panels/SimplePanel (where GWT is an item in the
top-level menu, Panels is an item in the GWT menu, and SimplePanel is a
final page of information to be displayed).
Each menu would set itself up if required by listening for a PlaceChange
event, and if a page recognised it was needed, it would display itself.
This, though, means that the MenuPanel needs to do a bit of setting up for
the menu items and associated pages.
It isn't actually quite the mess it probably sounds. All the hard work is
done in a hierarchy of a few abstract classes, so to create a new menu, all
you really need to is specify the menu text and the page it refers to, But I
do get the feeling I'm stretching the MVP pattern well out of shape in order
to get it all to work.

Ian,
When you mention your current solution fetches the MenuItem view from
the MenuPanel view, do you mean the MenuItem view(s) are already in
the MenuPanel view or do you mean the MenuPanel view acts as a factory
for MenuItem views? I have been experimenting a bit with the former,
though I imagine the latter would work. One approach I've also tried
for list based structures that might work for your list of Menu Items
is to make a function on the display interface to add the data
elements to build the MenuItem view from primitives:

I could easily be missing something important, but it seems like this should be a fairly easy thing for you to patch. My understanding is that the issue with GWT is that you need a 32-bit JVM, and in Mac OS X Leopard, the only way to get a 32-bit JVM is to use Java 5; the Leopard Java 6 is 64-bit-only. But in Snow Leopard, you can invoke Java 6 with java -d32 ..., and you will get a 32-bit JVM. Wouldn't this work for GWT hosted mode? Regards, Jim.

Re: GWT, MVP, and nested widgets
Thanks Jason,
I understand what you are getting at, and I have come across this before,
but hadn't considered using it here.
I'm using this project as an opportunity to learn and to see how 'right' I
can get it. If someone were paying me, then I wouldn't be so fussy, but my
feelings are this:
The MenuItem's presenter (and it's not GWT's MenuItem) should deal with user
gestures from the MenuItemView - I like the simplicity of 'Click-fire
event' and I don't like the idea that MenuItem+MenuItemView would not be a
stand-alone unit and would rely on parent widgets to sort out what is going
on. If the MenuItem presenter isn't going to do anything except pass through
a reference to the MenuItemView, and the MenuItemView is going to hold the
place token field, then why don't I just say to hell with it and get the
MenuPanel to send Labels to the MenuPanelView. It would save all that
faffing about.
I think I'd like to stick with the MenuItem presenter firing an event if I
can, and see if I can come up with a 'politically correct' answer to this.
I'm sure there must be someone out there, or something on the web which can
tell me how to do it, or explain why it's not possible, or give me a better
solution altogether.
If I find something, I'll post it.

I think you can quickly test this by disabling gzip compression in FireFox: http://forgetmenotes.blogspot.com/2009/05/how-to-disable-gzip-compres... This just causes the page to turn into garbage --- probably a server misconfiguration on my end. If the uncompressed size is particularly large then memory and compression time may be the limiting factor. Looking at the server stats its VM size doesn't appear to change during the first serialisation process, indicating that it doesn't want to allocate more memory. I have a feeling that memory's not the problem. Finally, what kind of objects are you serialising? Are you attempting to send something like Hibernate objects over the wire (or some other kind of proxied objects) which are causing unexpected database hits? Nope. The entire DB is being held in-memory. In fact, the way my app works is that the server logic calculates the delta needed to be sent to the client, constructs a packet of client objects from this, and then returns that packet as the result from the RPC call, so the stuff being serialised doesn't actually content to the objects in the DB at all. (My 400-object delta, the result of the initial DB sync, takes about 4s to generate.) The delta generation uses reflection and annotations to query the DB objects for properties that need to be copied into the delta. (The client is only allowed to see information from the DB that the user is allowed to have.) Simply by adding a cache for Field objects I managed to reduce the time taken for the delta generation by a factor of ten, so I suspect that reflection is dog slow with this JVM. What does the GWT serialisation system use? If it uses reflection, is there any way of persuading it to use byte-code generation instead? -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ─http://www.cowlark.com─ │ │ They laughed at Newton. They laughed at Einstein.

Re: ext-GWT vs GWT-ext
I don't think your response attacking me is productive. I wish you would stop your personal attacks. Please show me where I attacked you personally and I will rephrase it (just consider it a bug). Great, another clueless response. Maybe, maybe not. There's a huge difference between a platform / app server / Java and a library being GPL. A library being GPL means you need you release the source of your entire application, simple. An app server or Java being GPL has absolutely no effect on the licensing and distribution of your application while using GPL library means that you need to release all your code making it unsuitable for use in commercial products. So according to your analysis ExtGWT is unsuitable for commercial products. So what. The authors of ExtGWT are free to release their work under any license they choose. Just because the developers don't see their work serving your purposes...so what. A developer can choose any license they wish for their work. That is what the truth is so why are you calling me names? You somehow believe that ExtGWT developers should only release their work so you can use it in your commercial product. Other developers who are not distributing the ExtGWT library may not feel the same way. For example: A company that modifies open source software released under the GPL is not considered to be distributing (GPL v. 2) or conveying (GPL v. 3) when it runs the modified software as part of collaborative cloud computing. Therefore, the company does not have to contribute the modified software back to the community pursuant to the copyleft clause of the GPL. How about cases where the source code is not modified and the resulting java script is run over a network. Are you asserting that a javascript application run over a network requires that the source for the javascript be made available just because a GPLd library was used in generating the javascript that is run in the clouds. Our legal team looked at it and found numerous violations and we did report in on the Ext / ExtGWT forums but the posts were mostly ignored or deleted. SWT. SWT is licensed under EPL and EPL is well documented to be incompatible with GPL. See http://en.wikipedia.org/wiki/Eclipse_Public_License Since we are no longer planning on using ExtGWT, I have no intentions of burning any more time trying to get them to resolve this. Hmmn, let's think about this. The reason they changed in the first place was they had multiple incompatible licenses. You assert they are intending to violate the EPL. I suspect they will rewrite that as soon as they can. If you are going to make such statements or take a bait, do your homework first. Well you can keep using the ExtJS up to what it is 2.0.2 just like they said you could. They haven't changed that at all. They are no longer offering code under that license though. I did my homework. The developers felt that releasing with the type of license that would have been beneficial to you, would have allowed you to take what they felt was unfair advantage of their work. As developers, they choose (right or wrong for the ultimate success of their project) a more restrictive license that they felt was in the best interest of their development. I am sorry you don't agree. The SWT issue surely needs to be worked out but I still fail to see why a developer can not choose to release their new work under a different license than they did in the past. I honestly don't consider that dirty. Ok the developers of ExtGWT thought people were taking advantage of them. You are angry because you can't take advantage of them. Call me clueless all you want but I still fail to see how it makes the ExtGWT developers dirty. Anyway, thank you for your time.

HTML label tag
Is there a good way in GWT to give the functionality of the HTML label tag? I do not mean the Label widget here. I want to write code that produces label for=nameName:/label input type=text id=name/ from a Texbox widget and something else. I have emulated this by creating a ClickHandler, assigning it to each of the labels, and storing the label-to-textbox relation in a HashMap, but that is a lot of trouble to emulate a basic part of HTML. There should be an easier way. Doing that aso forces one to remove the connections so one does not leak memory. I know--it's hard to give an arbitrary id to a Widget; the ensureDebugId method should only be used for debugging, but there should be something. The alternative method of using label doesn't really work with GWT being so table-happy: labelName:input type=text//label as Grids would put the label and text box in different cells.

Re: Is Google Web Toolkit for me?
I'll throw in here
GWT is primarily a client side technology, so in your statement
better off sticking with PHP, JS, CSS, GWT would replace only the
last 2. PHP (obviously) only runs on the server. By choosing GWT you
will still need to choose a server side technology assuming you want
to connect to a database. Many people are familiar with PHP, so they
stick with that, communicating between client and server using JSON,
which GWT handles terrifically. You can also use Java for your server
side technology, and then you can very simply use GWT-RPC to handle
your communication. As for connecting to MySQL, Java will connect to
MySQL all day long, as will PHP. Just a matter of what syntax/stack
you are familiar with. The key thing to focus on here with GWT is
that it is an AJAX client library that makes it very easy to build
powerful AJAX web clients (or substitute your favorite acronym for
that) using Java syntax. If you use Java for your server tier, then
you get to use a teenie bit more GWT, but that's it.
Does that make sense?
Later,
Shaffer

I'm using Berkeley DB JE for one of my apps; it's a pure-Java
reimplementation of the old classic Berkeley DB non-relational database.
It's got some really nice Java reflection glue that combines well with
GWT's RPC glue. I can pull an object out of the database on the server
and pass it directly to the client in about three lines of code, and GWT
and Berkeley DB take care of all the plumbing. And because it's pure
Java, there's no extra dependencies on the server --- you just drop the
jarfile in WEB-INF/lib and it Just Works(tm).
A server-side RPC implementation can be as literally trivial as this:
DataObject getFromDB(int key)
{
try
{
return _index.get(key);
}
catch (DatabaseException e)
{
return null;
}
}

Re: Iframe = multithreading ???

Javascript will let you do it, provided the security rules let you (the page in the iframe must come from the same domain that your script does). I don't know whether it's possible to make GWT give you seamless access from Java, though --- you'd probably have to use Javascript trampolines.

Aligning Widget in RootPanel
Hi, Consider 2 code snipet below: My intention is to display Hello in Center of the page. 1. Using Label directly Label l = new Label(NITESH); l.setHorizontalAlignment(HasAlignment.ALIGN_CENTER); RootPanel.get().add(l); This displays it in center. 2. Label widget contained in Vertical/HorizontalPanel - HorizontalPanel hp = new HorizontalPanel(); Label l = new Label(Hello); hp.add(l); hp.setHorizontalAlignment(HasAlignment.ALIGN_CENTER); //hp.setCellHorizontalAlignment(l, HasHorizontalAlignment.ALIGN_CENTER); RootPanel.get().add(hp); - If we replace HorizontalPanel with VerticalPanel we get result the same. How would I display my label at Center of page if its contained under some Panel ? Am I missing something ? 10x --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: @SuppressWarnings(serial)
Andy, If you are using Eclipse (I assume you are since you are using the GEP), just delete that and you will see the warning: The serializable class DataServiceImpl does not declare a static final serialVersionUID field of type long You will also get 3 quick fix options: - Add default serial version ID - Add generated serial version ID - Add @SuppressWarnings 'serial' to 'GreetingServiceImpl' Any of those three options would work.

Re: DOM.getElementById() vs $doc.getElementById()
I found what works in IE, and does not break hosted mode, Firefox 3.5,
or Safari 4: Do NOT try to hide/show my application DIV or put my
widget into it. Hide the LOGIN_DIV as show, but put the
MainWindowWidget in the default root panel. So
private static void doLogin() {
...
logonPanel.setVisible(false);
RootPanel.get().add(new MainWindowWidget());
...
}
Returning to the login is now just
public static void showLoginDiv() {
RootPanel.get().clear();
RootPanel logonPanel = RootPanel.get(Workstation.LOGIN_DIV);
logonPanel.setVisible(true);
}
I was afraid this would break some things in my application, like a
DIV in which I occasionally open an IFRAME for downloading various
files from the server. However that still works fine.
Thanks for the help.
Now on to History.

From the comments on that
page:http://groups.google.fr/group/Google-Web-Toolkit/t/2b2ce0b6aaa82461
I've followed the link above. What I have works excellently in hosted
mode, as well as in Firefox 3.5, and Safari 4--the browser's password
manager is triggered, and the user is logged in. However I've still
no luck with IE7 (and no Javascript error indicated).
Does IE have a problem with hiding/showing DIV's? The form behaves
properly. injectLoginFunction() works (see below), the doLogin()
method is called, and the user logged in (so says my server's
console). As you see below, on a successful login, the LOGIN_DIV in
the original panel is hidden, the APPLICATION_DIV is made visible, and
the application's MainWindowWidget is created and added to the
APPLICATION_DIV. (After a user logs off the server, the showLoginDiv
() method is called, and we start over.)
As I said, this works in hosted mode, Firefox 3.5, and Safari 4. In
IE, after the login completes, all I see is a blank browser, and
Done in the lower left message area (no JS error).
Is there another way to handle this that will work with IE?

Hi Dave, I would have to agree that UI Standards is a pretty broad term here, so it's hard to tell what exactly you or the higher-ups in your company are referring to.

Re: @SuppressWarnings(serial)
Sorry, I was reading that the reason that Servlets implement the Serializable interface was so that server vendors had the option of hibernating a Servlet's state for the purpose of load balancing or server replication. The only 'state' that I can think that a Servlet could have would be a static object that did something like count how may times the Servlet has performed a particular task. As there are far better ways of doing that sort of thing, I guess that Servlets should be stateless and therefore don't need to be Serializable. However, as they have to implement the Serializable interface, suppressing the warnings is neater than generating IDs all the time.

Re: Hyperlink Token and Parms
Thanks for reply, but I can only do Window.Location.replace onHistoryChanged. So my HistoryHandler fires twice.

Re: GWT, MVP, and nested widgets
Ian,
we've taken a little different approach than you have. Let me explain
the setup we have for the navigation section of our application:
NavigationPresenter - the presenter for this section of the
application
NavigationDisplay - a presenter-utilized, view implemented interface.
HasMenuStructure - an interface, extended by NavigationDisplay, used
for adding menuitems and submenus.
NavigationPanel - a view layer object, extends Composite, implements
NavigationDisplay
We're using an adaptation of the GWT MenuBar widget that implements
the HasMenuStructure interface.
interface HasMenuStructure {
...
void addMenuItem(String html, Command cmd);
HasMenuStructure addSubMenu(String html, boolean hasChildMenus);
...
}
hasChildMenus is important in our particular use, but may not be in
yours.
Using this setup, we can create the menu structure in the presenter
dynamically, without worrying about the underlying display details.
The html and cmd parameters for addMenuItem() are read in from a
configuration file on the server, filtered based on authorization
information, then passed to the presenter to allow the view to show
things to the user. It would be trivial, I would think, to replace the
Command interface with a ClickHandler interface, but since MenuBar
made use of commands, we went with that.
HTH...

Thanks Jason,
I understand what you are getting at, and I have come across this before,
but hadn't considered using it here.
I'm using this project as an opportunity to learn and to see how 'right' I
can get it. If someone were paying me, then I wouldn't be so fussy, but my
feelings are this:
The MenuItem's presenter (and it's not GWT's MenuItem) should deal with user
gestures from the MenuItemView - I like the simplicity of 'Click-fire
event' and I don't like the idea that MenuItem+MenuItemView would not be a
stand-alone unit and would rely on parent widgets to sort out what is going
on. If the MenuItem presenter isn't going to do anything except pass through
a reference to the MenuItemView, and the MenuItemView is going to hold the
place token field, then why don't I just say to hell with it and get the
MenuPanel to send Labels to the MenuPanelView. It would save all that
faffing about.
I think I'd like to stick with the MenuItem presenter firing an event if I
can, and see if I can come up with a 'politically correct' answer to this.
I'm sure there must be someone out there, or something on the web which can
tell me how to do it, or explain why it's not possible, or give me a better
solution altogether.
If I find something, I'll post it.
Thanks again,

Ian,
Ok, I think I understand what are trying to do. Let me expand a bit on
the addMenuItem( Object i..); example in something a little less
abstract. First, I'm assuming your MenuItem is not equivalent to the
GWT MenuItem class, if it is the solution would be different. Note, I
don't have a full example so mileage may very. The approach is meant
to deal with MVP of list type interfaces, where the list items (i.e.,
MenuItem) bubble events up to a list presenter (i.e. MenuPanel).
The example assumes that instead of each MenuItem reporting
PlaceChange events, MenuItem selection events are bubbled from the UI
up to the MenuPanel presenter (through its view) and the MenuPanel
presenter fires the PlaceChange event. Effectively, a MenuItem's
display becomes a simple widget within MenuPanel's view and doesn't
require its own presenter (the presenter's work is handled by
MenuPanel's presenter).
First, some simple setup:
public class MenuPanel {
interface Display {
void addMenuItem( String label, String token );
HasSelectionHandlersString getMenuItemSelectionButton();
void clearMenuItems();
}
...
}
The above class shows a possible piece of the MenuPanel display
interface. I am assuming in the above that a MenuItem takes a label
that defines how the UI displays the object and the token as you
describe above for the associate place/location when the item is
clicked. In this example, the MenuPanel presenter determines the menu
items required for the current place and calls addMenuItem to tell the
MenuPanel view the MenuItem widgets to construct in the UI. The
clearMenuItem method can be used clear the MenuItems to rebuild the
specific items when the page changes. Notice that I included another
Display method called getMenuItemSelectionButton(), this returns an
object the MenuPanel presenter can add a handler to so it can detect a
MenuItem selection event. Here's an example of the bindDisplay method:
void bindDisplay( Display display ) {
this.display = display;
//Listen for a token selection when the user picks a MenuItem
display.getMenuItemSelectionButton().addSelectionHandler(
Re: hosted mode trouble
Otherwise, you're going to have problems with the SOP (Same Origin Policy). Basically javascript has a rule that you can't make requests to a server other than the one the script originated from. There are ways around this, but I'll let you do the research on that, or alternately, compile and deploy each time you make a change.

Re: Iframe = multithreading ???
There is just 1 JS thread. Regardless of URL or IFrame. The limit of max 2 connections is purely based on URL, not on per IFrame basis. IE8 allows more than 2, I forgot the exact number. To work around the connections limit you can spread web resources over different hosts in the same domain. Getting access to static classes in different IFrames can works but: 1) security restrictions might stop you from calling from one IFrame to another. 2) GWT code is obfuscated and can be totally different with every change you make. So in order to get access to some static classes, you will need to expose them through JSNI.

Re: Is it a bug in DialogBox?
Not sure if its a Bug of DialogBox
my guess is its a bug of decorator panel
any way your problem is you are setting size of DialogBox which is creating
the problem
solution 1) remove setSize
solution 2) if you want to use setSize then wrap your content in vertical
panel
something like this
class ClothingForm extends DialogBox {
public ClothingForm() {
setText(Clothing);
//setSize(30em, 30em);
Button ok = new Button(OK);
ok.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
ClothingForm.this.hide();
}
});
VerticalPanel content = new VerticalPanel();
content.setSize(30em, 30em);
setWidget(content);
content.add(ok);
}
}

Re: Unable to Find 'com/google/gwt/widgetIdeas/libIdeas.gwt.xml'
I might as well document this for myself so I don't forget...
To use the incubator in GWT 1.7 you'll need to do the steps above, and add
something like this to your build.xml file:
fileset dir=${gwt.sdk} includes=gwt-inc*.jar/
The build.xml is only created if you used webAppCreator to create the
project, and as far as I know that's needed if you want GWT to output files
like the old version... (I'm using GWT/PHP on my wamp localhost server, so I
need the files.)
Here's an example of my build.xml (Note: I never use hosted mode, I just
copy over files to a gwt folder on localhost).
?xml version=1.0 encoding=utf-8 ?

Re: Is Google Web Toolkit for me?
Hey Spierce,
If u require AJAX enabled web app, GWT is viable option but it seems u
dont have much hands-on with JAVA/its related technology and learning
the whole JAVA web App stack is quite an effort from scratch.
There is no doubt that choosing GWT means ur web app has to be purely
Java-based.
As rightly pointed out in above post, u would require GWT (client-
side) and Spring/Hibernate or other similar technologies (server-side)
to create a maintainable, efficient Java web app. Thus u would be
learning a whole new techs to bring ur web app live.
If u r comfortable with Php world, I would suggest u stick to it and
find ways to introduce Ajax within it, in the end ur goal is not to
learn different technologies or be an architect but to build ur web
app, make it live.
Hope it doesnt confuse u,

I'll throw in here
GWT is primarily a client side technology, so in your statement
better off sticking with PHP, JS, CSS, GWT would replace only the
last 2. PHP (obviously) only runs on the server. By choosing GWT you
will still need to choose a server side technology assuming you want
to connect to a database. Many people are familiar with PHP, so they
stick with that, communicating between client and server using JSON,
which GWT handles terrifically. You can also use Java for your server
side technology, and then you can very simply use GWT-RPC to handle
your communication. As for connecting to MySQL, Java will connect to
MySQL all day long, as will PHP. Just a matter of what syntax/stack
you are familiar with. The key thing to focus on here with GWT is
that it is an AJAX client library that makes it very easy to build
powerful AJAX web clients (or substitute your favorite acronym for
that) using Java syntax. If you use Java for your server tier, then
you get to use a teenie bit more GWT, but that's it.
Does that make sense?

I'm using Berkeley DB JE for one of my apps; it's a pure-Java
reimplementation of the old classic Berkeley DB non-relational database.
It's got some really nice Java reflection glue that combines well with
GWT's RPC glue. I can pull an object out of the database on the server
and pass it directly to the client in about three lines of code, and GWT
and Berkeley DB take care of all the plumbing. And because it's pure
Java, there's no extra dependencies on the server --- you just drop the
jarfile in WEB-INF/lib and it Just Works(tm).
A server-side RPC implementation can be as literally trivial as this:
DataObject getFromDB(int key)
{
try
{
return _index.get(key);
}
catch (DatabaseException e)
{
return null;
}

[gwt-contrib] Re: New API proposal: BatchedCommand
Could this also be used as a general pattern to batch DOM updates from multiple Widgets performing updates? e.g. a current approach to avoid the overhead, of say, installing a dozen widgets, is to concatenate all the HTML together, slam it into innerHTML, and then wrap the widgets around the HTML. But this rather breaks the nice OO design people are used to with widgets. Templating is an alternative, but I'm wondering, why can't we make all of the attachment stuff happen via a batch queue. A special optimizer on the queue could even recognize instances of when DOM updates can be coalesced and leverage documentFragment or innerHTML. e.g. VerticalPanel vp = ... vp.add(new Label()) vp.add(new Label()) The objects are constructed, but the HTML mutations are deferred/queued. When adding a DOM mutation to the queue, you could check if existing queue data isOrHasChild the new DOM mutation element, and if so, just modify the queue element (coalesce) rather than appending another queue item. Then, when processing the queue, you only need to add the roots to the DOM, attaching/modifying enmasse. This would preserve the OO-ness of constructing widget hierarchies without requiring 'foreign' string-based templating. -Ray On Wed, Sep 2, 2009 at 5:13 PM, Bruce Johnson br...@google.com wrote: On Wed, Sep 2, 2009 at 6:07 PM, Scott Blum sco...@google.com wrote: I do agree with John that we should really discuss how this can be implemented.

No trick, it's as bad as you'd hope it wasn't. On the positive side, it's already been done -- I'm just augmenting the tests for the various subsystems such as RequestBuilder and event dispatching to make sure we tighten the correctness noose as much as possible. Longer term, Bob and I both would really like to find a general mechanism for making this pattern easy to do from any path into a GWT module from the outside, exactly along the lines of what Matt was talking about. I think rolling this functionality into gwt-exporter (and then rolling that sort of functionality directly into GWT proper) will get us pretty far down the road.

[gwt-contrib] Re: A number of layout-related changes.
Just a few remarks relating to the design changes...
*RequiresLayout.java* : We expose now animation routines in this interface.
With those new animation methods this interface becomes more constraining
when you have to provide a subclass. What about a panel provider that would
not want to implement any animation stuff ? Maybe something like
RequiresLayoutWithAnimation and RequiresLayoutWithoutAnimation or design
something that would lead to optional animation would be nice.
*LayoutPanel.java* : ProvidesLayout is replaced by both interfaces
RequiresResize and ProvidesResize. IMHO this split seems to be redundant.
Why this separation if at the end onLayout() calls onResize() and onResize()
calls onResize() for all its children ?
*ProvidesLayout.java:* This class is removed and replaced by ProvideResize
but in the providers side, we have two different interfaces RequiresLayout
and RequiresResize ...
Joel, would be very interested to understand the limitations you got in the
previous design ….

[gwt-contrib] Re: Focus/blur on a group of widgets?
Oooh, sorry. You were asking the *hard* question, not the easy one. I think the short answer is that there's no easy answer. See http://code.google.com/p/google-web-toolkit/issues/detail?id=1431 for some of the reasons. Another short answer is I don't get this stuff but Joel does. rjrjr On Wed, Sep 2, 2009 at 12:13 PM, Ed post2edb...@hotmail.com wrote: Tanks Ray, I understand what you mean but don't really see how this could solve my problem. My problem is to detect a single focus/blur event of a group of widgets. Looking at your explanation I do translate these events to a general ValidationChange event. However, to trigger the validation of my composite widget I have to detect a single blur (like explained above of the examples). Reading your explanation; my problem is the implementation of this semantic event as the client won't see this blur/focus event directly, but the ValidationChangeEvent. Is there anyway to analyze the upcomming gwt events, when receiving a gwt event? In this way I can see if a focus event of one of the widgets in the group is following the blur event, so I can decide if the blur event is a blur of the whole group of widgets --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
