Re: prerequisities of GWT to develop JPA
Read the tutorial Rakesh suggested. Hasan's sample has only one domain class and it works "by accident". If you have a more complex domain model, classes referencing one another, then this approach will not work as is. ORM libraries add proxies, which GWT serializer can not handle.

java to javascript code conversion question
I have two modules, module 1 & module 2 with module 2 inheriting module 1. When the code in module 2 gets converted to JavaScript, is gwt converting only the classes in module 1 used by module 2 or does it convert everything in module 1? I have this common module that contains code used in several other modules. Some of the panels are used in one other module, other panels are used in more than one module. When one module loads up I do not want the browser to load javascript code that is never used in that module. I am using GWT 1.5.

For PHP code, you might have to refresh the hosted mode browser (not recompile, just F5), but you might not even have to do that. If your app has a search button which does a typical search, then provided just the PHP code has changed (and not the GWT code which displays the results), you can just click 'Search' again.

HowTo: Module Inheritance in Eclipse
I fought with this for awhile, and finally figured out how to do this. I hope it can help someone else as they progress through their own GWT project. The problem arises when you want to create a GWT application, but not cram all your code in one huge monolithic GWT project. If you can isolate functionality into modules, you are much better off. Plus, you can let others make use of your hard work and contribute to GWT. In my application, I needed user authentication/authorization, but I certainly didn't want to put the code in my top level project. I wanted it generic enough where it could be used by not only the current project, but future endeavors. If I was writing a plain ol' java application, its really a no-brainer; you create a separate project, lets call it 'commons', and have your project to use the commons project on its build path. GWT is almost this simple, but it has a few gotchas that can drive you crazy. My projects are a bit more complex than the following, but for the sake of simplicity, lets say we have the following. I will highlight the most important features. I'm using the following. Hopefully my explanations of eclipse settings are similar to yours. Mac OSX Eclipse v 3.4.1 GWT v 1.7.0 loginmanager - an eclipse project - client folder: contains widgets like a LoginWidget, AccountManagementWidget,etc. Listeners can be hooked up to a anonymous event bus where you can receive notification about signin, signon, account update, etc. - server folder: contains a servlet with signIn, signOut, updateAccount, etc. Account persistence is in a mySQL database. WEB-INF/web.xml contains this among other things... LoginManager org.reue.loginmanager.server.LoginManagerServiceImpl LoginManager /loginmanager/login I used the Eclipse GWT plugin, so I automatically get a Loginmanager.gwt.xml file created for me. This works great when developing this project module, but it will not work when you want to use this module in another project. It contains an tag that points to the class I used when I ran the module standalone during its development. Lets make another module without the . I called mine login.gwt.xml. It contains the exact information as Loginmanager.gwt.xml, but does not include the Now i have loginmanager -src -org.reue.loginmanager +client +server login.gwt.xml loginmanager.gwt.xml ... MyApp - An eclipse project - I want to push a button and have the LoginWidget from the loginmanager module show on the screen. I should be able to access the anonymous event handler bus provided by the loginmanager module to register myself as a listener for the events that my loginmanager fires. I should not have to write any authentication/authorization/ persistence code. - client folder - contains MyApp.java which implements EntryPoint. I just have a button that when pushed, instantiates a new LoginWidget, provided by the loginmanager module, and shows it on the screen. I will also register myself as a SignInHandler which is provided by my module. - server folder - no server code As you can see in this example, the application code is tiny. All the work is done in the module. When I click the button, the LoginWidget will show where I can enter my credentials and then click login. An RPC call will be made to the servlet provided by the loginmanager module, and I didnt have to write a single line of code as a user of the module. (Obviously, one will have to create the MySQL database, schema, etc) but the point here is that my application code is not polluted by all the common authorization code. Steps to get the MyApp project to properly inherit the loginmanager module for design-time and runtime use: 1) Remember to create the extra *.gwt.xml file in your module so you can inherit the module. Otherwise you will get complains of having multiple entry points. 2) With the MyApp project selected, edit the build path Click: Project | Properties | Java Build Path Click the Projects tab Click the Add... button and add the loginmanager project Click the Source tab Click the Link Source... button The Link Source dialog shows For 'Linked Folder Location', Click Browse... and navigate to the loginmanager project. You want the src folder here. For 'FolderName', you can give it any name you wish. I would just name it after your module, like loginmanager. Click Finish Click OK on the Properties dialog In your Eclipse Package Explorer, you should now have 'loginmanager' as a folder under your MyApp project **Notes When setting the build path of your app project, you must use the 'Link Source' option if your module contains any servlet code. This was one of my main stumbling blocks. The LoginWidget would show up fine, but when I clicked the login button, which made an RPC call, I would get a ClassNotFoundException. If you do not link source, the classes will in war/classes will not have your server code. 4)
Re: How can I add a MouseOutHandler to a FlexTable cell?
Based on Kelo's example above:
public class BocaJrsTable extends FlexTable implements
HasMouseOutHandlers {
// ... as above, but add the following:
public int[] getCellForEvent(final MouseEvent event) {
final Element td =
getEventTargetCell(Event.as(event.getNativeEvent
()));
if (td == null) {
return null;
}
final Element tr = DOM.getParent(td);
final Element body = DOM.getParent(tr);
final int r = DOM.getChildIndex(body, tr);
final int c = DOM.getChildIndex(tr, td);
final int[] idx = new int[] { r, c };
return idx;
}
}
someTable = new BocaJrsTable();
someTable.addMouseOverHandler(new MouseOverHandler() {
@Override
public void onMouseOver(final MouseOverEvent event) {
final int r = row(event);
...
}}
);
public static int row(final MouseEvent event) {
// note that in general, events can have sources that are not
Widgets.
BocaJrsTable sender = (BocaJrsTable) event.getSource();
final int[] idx = sender.getCellForEvent(event);
if (idx == null) {
return -1;
}
return idx[0];
}
I hope that helps,.
Cheers,

Re: GWT architecture MVP/EventBus (mentioned at Google I/O)
Hi, I created a framework, Mvp4g, to easily build gwt application using Mvp + event bus + DI thanks to an xml file. A new version is now available (mvp4g-0.13-beta). You can: -Set an event bus without creating extra classes. -Configure which presenter handles an event. -Inject a view and one to many services into the presenter. I also added the Pure Mvc example (that you can see here: http://employeeadm.appspot.com/) but implemented with the Mvp4g framework in order to easily compare the two implementations. To ensure quality, the framework is covered by JUnit tests. It's still a beta version because I'd like to add a Place service before a version 1.0 (I'd actually like people ideas and remarks about the best way to manage history before starting, http://groups.google.com/group/mvp4g/browse_thread/thread/3d3e1753c43f1270) The framework and examples can be downloaded here: http://code.google.com/p/mvp4g/. I would like people opinions on it. Thanks :) On Jul 20, 7:39 am, Norman Maurer wrote: > I already ported my app to use gwt-presenter.

When I set up a new project to test my ability I noticed plugin puts come jar in template folder (war\WEB-INF\lib) and I start receiving datanucleus errors.. Then I delete all jars in this folder and copied my own.. viola! code run again.. 1- Do I misunderstand?

Newbie - HTML pages
Hello everybody.. I am just beginning with GWT development and this is my first post. I have some experience with web development. I am using Eclipse as IDE for developing. I created an GWT project using the GWT plugin for Eclipse. So far, so good... Eclipse created the packages, classes, etc.. I am able to change the client and the server-side, make deploy on tomcat. Everithing is working fine. My question is: I need to develop an application that will heavy many pages. Do I need one GWT project to each page of my application? Or can I have many HTML's in my WAR folder and only one project? My idea is to have some links in the top of these pages. Each link to a page of the application. I am not sure how to do that. I've searching for in the web, but I got nothing about. Can anybody give me a little help about?

Re: Asynch call does not return
I meant to mention that you'd probably want to save the finished results in a database, and maybe keep the last few jobs per user. My wife runs jobs that take weeks to process. Saving all on the server would let you come back the next day or 10 minutes later, from a different browser instance. This would also make sense for any type of job that takes a long time, like shipping a package, etc, not just computationally intense ones.

Re: Asynch call does not return
Assuming you can't make the code run faster, one technique I've seen done is to have the the RPC return when the job has been submitted. The user can then check on a "jobs" page to see a list of jobs from a database. Unfinished jobs can say "processing" until the server side has updated the list that it has completed/failed/etc. Save the results on the server side (possibly write the bare minimum needed to construct the final object, whether it's a report or a rendered image, etc) and for finished jobs on the jobs page, selecting a finished job will stream back the finished binary/display a widget/etc. On Tue, Aug 11, 2009 at 3:43 PM, lakshmi thyagarajan < tlakshmipr...@gmail.com> wrote: > Hi, > > One of my server side methods requires about 20 minutes to complete > (involves executing a series of scripts and a whole lot of iterations to > execute a complex algorithm). > An asynchronous call to this method from my client does not return back to > the client even after the method finishes execution.

Re: Asynch call does not return
This is actually a very bad idea! IE will most probably kill the request before the server does. You should see if you can implement this in an asynchronous operation on the server side and check for the state on regular intervals.

Asynch call does not return
Hi, One of my server side methods requires about 20 minutes to complete (involves executing a series of scripts and a whole lot of iterations to execute a complex algorithm). An asynchronous call to this method from my client does not return back to the client even after the method finishes execution. My GWT application is deployed in a Tomcat server. The session expiry time in the tomcat server is set to 30 minutes. This problem however does not exist in the hosted mode.

Re: Entire Website in GWT
Hi Jack -- this completely depends on what you want to do. You can build a standard website using whatever tool/frameworks, etc. you want and you can embed GWT widgets into pages. You could also build your entire site in GWT. Normally what people do is have a single entry point, and then dynamically add / remove components from the application based on user input. I like the idea of putting nearly 100% of the presentation logic into the client's browser and not having this served from the server. I have always found that model painful. This is the pattern I am using now for building a fairly complex application. The only thing I go back to the server for are stateless service requests for data (not presentation). I found the single entry point model slightly limiting, especially since I want to have a couple different entry points based on the initial URL ( e.g. http://host/app/admin or http://host/user/davis ). I posted a blog on how to use multiple entry points here: http://zenoconsulting.wikidot.com/blog:16 Regards, Davis On Aug 11, 6:09 am, Jack wrote: > Hi Guys, > > I want to develop a portal in GWT 1.5.

Re: A newb needs your help with hyperlinks
You'll be better off using an Anchor instead of a Hyperlink - it's the
same visually, but you get to control what happens on click by adding a
ClickHandler. You should find it results in much cleaner code.

Re: Best practices for screen layout in GWT
I personally did the layout all in code. I originally used a DockPanel and realized that I was only using WEST, NORTH, and CENTER. And being in a DockPanel limited me. So I ended up swapping out (Fairly easily) for a VerticalPanel with either Widgets or a HorizontalPanel in it. While the widgets were all set in code, I still have a lot of flexibility to change things with CSS. This also allows the widgets to all "speak" to each other if you so choose.

A newb needs your help with hyperlinks
I been assigned the task of making hyperlinks work, change color on
hovering and clicking, and being able to enable and disable the
links. I have the color changing part working and I thought I had the
disable/enble working, but now I can not get the onClick to be
reconized. Below is the code to extend the hyperlink so I can add the
enable/disable methods.
public class lawHyperlink extends Hyperlink implements
SourcesClickEvents, HasClickHandlers {
// define the HTML hyperlink
private Html hyperLink;
private final String str;
private static HyperlinkImpl impl = GWT.create(HyperlinkImpl.class);
public lawHyperlink(String s1, String s2) {
str = s1;
hyperLink = new Html("" + s1 + "")
{
protected void onRender(Element target, int index) {
super.onRender(target, index);
el().addEventsSunk(Event.MOUSEEVENTS);
el().addEventsSunk(Event.ONCLICK);
}
};
enabled();
} // end of lawHyperlink constructor
public Html displayHyperlink() {
return hyperLink;
}
public void disabled() {
hyperLink.removeAllListeners();
hyperLink.addStyleName("gwt-Hyperlink-disabled");
hyperLink.setStyleAttribute("color", "#E0E0DA");
} // end of disabled method
public void enabled() {
Listener listener = new Listener() {
public void handleEvent(BaseEvent be) {
Html h = (Html) be.getSource();
String c = h.el().getStyleAttribute("color");
// Info.display("Listener color before test ", c);
c = c .equals("#ff00ff") ? "#ff" : "#FF00FF";
// Info.display("Listener color after test ", c);
h.setStyleAttribute("color", c);
}};
hyperLink.addStyleName("gwt-Hyperlink");
hyperLink.setStyleAttribute("color", "#00ff00");
hyperLink.addListener(Events.OnMouseOver, listener);
hyperLink.addListener(Events.OnMouseOut, listener);
} //end of enabled method
@Override
public HandlerRegistration addClickHandler(ClickHandler handler) {
Info.display("addClickHanler called ", "from lawHyperlink");
return addHandler(handler, ClickEvent.getType());
} // end of addClickHandler method override
@Override
public void onBrowserEvent(Event event) {
super.onBrowserEvent(event);
if (DOM.eventGetType(event) == Event.ONCLICK &&
impl.handleAsClick
(event)) {
History.newItem(getTargetHistoryToken());
DOM.eventPreventDefault(event);
}
} // end of onBrowserEvent method override
} // end of lawHyperlink class definition
I add the onClick handler in another class that puts it on a panel
that gets added to the rootPanel.
lawHyperlink firstPage = new lawHyperlink("|< First Page",
"FirstPage");
firstPage.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
MessageBox.alert("onClick", "Clicked First Page", null);
}});
linkPanel.add(firstPage.displayHyperlink());
Everything displays fine and the trace looks good, but the onClick
event is not being reconized. I believe I'm missing something from my
lawHyperlink class, but I have not been able to determine what. Any
help will be greatly appreciated.
Thanks,
Ray

Re: location for images
I had problems with this too.
Regular images, that are NOT in an Image Bundle can go in your war
file. I typically keep a WAR/images folder and drop everything in
there. Then a reference to them would be Image test = new Image(images/
test.png); if the image file is WAR/images/test.png
ImageBundle pictures have to be kept in the code files. It's kind of
confusing, but essentially these pictures get compiled using the code
and put into one single image. They will be kept somewhere in (typical
folder structure) com/client/[AppName]/...
An example from the API:
@Resource("com/client/myapp/icons/btn_cancel_icon.png")
public AbstractImagePrototype cancelButtonIcon();
Hope this helps.

Re: Will I have memory leaks if a Widget is removed from Panel without call to HandlerRegistration#removeHandler()
Hi, If you remove the widget from the view and you keep no reference to that widget then normally the widget will be garbage collected. You only need to keep the HandlerRegistration and call remove if you want to stop listening to the widget, while the widget is still being used somewhere.

Missing quick fix in the eclipse plugin for RemoteService with super interfaces
Using plugin version 1.7.0 and Eclipse Galileo.
When a RemoteService interface defines a method, the corresponding
Async interface is marked as error and there is a quick fix which
generates the method in the Async. Good.
However, when the method is defined in a super interface of the
RemoteService, the Async is marked as error, but the quick fix is
missing.
Here is how to reproduce:
public interface Super {
void x();
}
public interface GreetingService extends RemoteService, Super {
}
public interface GreetingServiceAsync {
// The error is reported that x() must be declared, but there's no
quick fix
}

Re: Does anyone has a nice written class for bypassing SOP restrinctions
Thanks for the code. This actually covers well the GET part, but as
you say, not the POST.
Thanks cause it is still very interesting implementation.
Does anybody has written or seen around a similar code that would also
support POST ?
Thanks for the help.

Re: How to split a large application?
Hi Stefan, take a look at the blog entry that I just wrote. It may give you some idea on how to do this: http://zenoconsulting.wikidot.com/blog:16 I split my app up into multiple GWT entry points that all build in the same project. It has been working great so far.

Re: How to split a large application?
I already described how I do it. I can not just post the complete code since I am not allowed to do that. Through JSNI I just define a property on the DIV element. This property maps back to the GWT applications so acts as a communication gateway. nothing special really.

Re: How to split a large application?
Nathan, The use case is indeed not what you think it is. In your case I could just deliver the main application as a widget library and build the final application from this jar. It is not possible to compile both the main application and child applications in one unit because these are developed by different groups/companies. The sub applications are installed separately from the main applications and the main application is updated separately from the sub applications as well. When you create a portal you don't always write/compile all the portlets that are being deployed. Per installation the version and type of portlets can also be different so it is just impossible to deliver everything as one big application. We do not host the service either, so the portal is delivered as an ear that will allow appserver admins to configure the installed applications at runtime. So we just don't know what applications are used and they are not even from our group/company.

Programmatic resize of root panel
I have a Tree widget within a HorizontalSplitPanel within the root panel. I have an intermittent problem with the hosted browser at process start--the TreeItems are collapsed to the vertical center of the enclosing panel. Resizing the browser window, even by a very small amount, causes the tree items to paint normally, and everything works as desired from that point. Does anyone know why there would be an intermittent problem painting the tree? Is there a programmatic method to resize the browser window?

server side expected behaviour?
Hello, I am experimenting with new GWT plugin + GWT 1.7 and I notice the following: I create a new GWT only application and start it in debug mode, if I get on the code view of eclipse and edit anything on the client side, the changes are loaded instantly after I reload the page, if I edit anything on the server side (package com.niceapp.server) for example the class GreetingServiceImpl.java nothing happens: the only way to see it is to stop the engine (embedded jetty in gwt plugin) and start it again. I just wanted to know if this is the expected behaviour, since using jetty in eclipse normally this doesn't happen.

Hi Ed & Nathan, the crux of the matter is, that I really can't use a single compilation unit. There are potentially hundreds of sub applications that are automatically generated.

Re: Spring and GWT integration
Hi P.G. I've seen a lot of ways to achieve that integration, and none looks complicated. The fact is that spring-gwt integration is easy (thanks to R. Jellinghaus' refactoring of the RemoteServiceServlet), which explains the plethora of libraries. Hibernate-gwt integration on the other hand is hard, that's why there are only 3 (afaik) out there of which only 1 (imo) is to be taken seriously. I guess it all comes down to : - what kind of flavour you prefer - if you like annotations or XML - prefer convention over configuration - whether you can live with a certain 3rd party dependency or not - how much documentation you need - how big and active the supporting community is Especially the later point is a threshold for commercial adoption when arguing in favour of a library in technical meetings, so maybe that's the answer you are looking for ;-) On Aug 11, 11:04 am, "P.G.Taboada" wrote: > Hi, > > I have seen a lot of (quite complicated) Spring and GWT integration > approaches, and I wonder why noone is using the autowiring bean bean > factory to simple auto-inject the required beans into the GWT RPC > services. > > http://pgt.de/2009/07/17/non-invasive-gwt-and-spring-integration-relo... > > I have been using this approach for a while.

Re: How to split a large application?
But why not make a direct link from the main app to the sub app? And why not make it one compiler unit ? I have the same now: I have 4 app's: login, profile, admin, declare. After the login I decide which app to load... When I start using 2.0 I will make it one compile unit and do the same switch... They are just separate eclipse projects and just linke them together when using 2.0... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Java To Java RPC
Possible, yes. Problematic, yes. The basic problem you'll run into is that GWT RPC uses a custom version of JSON for serialization. Essentially, you would have to recreate the GWT-RPC mechanism for your thick client, which may or may not be difficult. I can't say how difficult, since I've never had to do it, but I would wager that it would be easier to either 1) Leave GWT-RPC behind in favor of the more standard XML or JSON methods. 2) Forget about having a thick Java client. Personally, I would prefer 2, but I don't know your particular use case.

Re: How to split a large application?
I agree with Ed, but don't know that I fully understand the use case... I'm doing a similar thing without iframes or runAsync. Essentially, I created a PresenterMap that extends HashMap where Presenter is an interface that has an "presentIn (HasWidgets)" method. This method does the necessary work to load the UI into the given panel (of course, I separate UI-specific concerns into "view" classes). What this allows me to do is generate a navigation pane that has no knowledge of the underlying pages and can be configured for whatever navigation needs a given user/admin has. I know I'm kind of leaving things unclear, but I don't want to go into too much detail without understanding your needs.

In order to achieve this I added the module name of the sub application after the module name of the main application and included the source and class directories of the sub application in the class path of the HostedMode execution. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Problem cascading styles in GWT
Hello, i'm trying to use CSS with gwt (cascade styles).
I have this code:
hpMain.add(hp1);
hpMain.add(vp1);
hp1.add(lb);
hp1.add(new Label("in hp1"));
vp1.add(new Button("B 1"));
vp1.add(new Button("B 2"));
vp1.add(new Button("B 3"));
hpMain.setStyleName(styleMain);
vp1.setStyleName(styleVP1);
hp1.setStyleName(styleHP1);
lb.setStyleName(styleLabel);
where
private String styleMain = "GadgetTest1";
private String styleHP1 = "hPanel1";
private String styleVP1 = "vPanel1";
private String styleLabel = "lbl";
CSS file:
.GadgetTest1 .hPanel1 .lbl{
color: blue;
}
.GadgetTest1 {
font-size: 11px;
font-family: Arial Unicode MS, Arial, sans-serif;
border: 1px solid red;
width: 100%;
}
The label with style "lbl" has a blue color and inherits style
"GadgetTest" (set to main panel). The problem is that only the font-
family tag is recognized (the font size is still large which is
implicit) but I used firebug plugin and i saw that the label object
also inherits the font-size tag but it doesn't show on the browser (if
i modify it nothing happens). What's the problem here ? Is it a bug?

Re: XML Parsing and NamedNodeMap
I saw that the implementation of that IF depends on the browser. This however should be transparent to the GWT programmer I'd say... Any further hints?

Re: How to split a large application?
Hi All, Why not use the Async functionality in 2.0? (to lazy load/run the code for the other apps).

Re: How to split a large application?
Hi David, I started my struggle to launch sub applications. The first results using an iframe to load the sub applications look promising. Yet, until now, I did not manage to run it in the hosted browser. Do you know / think that it is possible at all? When I try to start a sub application the hosted browser loads the iframe but complains that it can not find the requested module. It gives the hint that "all active GWT modules must be specified in the command line arguments". Unfortunately I did not find much material that documents the command line of the HostedMode.java class. --Stefan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Spring and GWT integration
Hi, I have seen a lot of (quite complicated) Spring and GWT integration approaches, and I wonder why noone is using the autowiring bean bean factory to simple auto-inject the required beans into the GWT RPC services. http://pgt.de/2009/07/17/non-invasive-gwt-and-spring-integration-reloaded/ I have been using this approach for a while. It is easy to setup and works perfectly. Would appreciate any comments. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT and PHP
Cant you just use HttpRequests to the php pages (using query strings to send the data), and set them pointing to absolute urls for your sever? That should work, I think.

Re: Best way for changing UI layout on browser size changes? Deferred binding an option?
My advice would be to use alternative sets of CSS for different sizes, and switch between them.

Re: prerequisities of GWT to develop JPA
Hi Tolga, Below is a simple demo [1] from one of my GWT presentations implementing GWT-JPA integration. It's configured as to connect HSQLDB but you can find a commented configuration to connect to MySQL as well (see [2])... you can check it out and run using GWT Eclipse Plugin - you don't need any extra tool: svn checkout http://faculty-gwt.googlecode.com/svn/trunk/examples/hellogwtwithjpa-addwidgetshellogwtwithjpa [1] http://code.google.com/p/faculty-gwt/source/browse/#svn/trunk/examples/hellogwtwithjpa-addwidgets [2] http://code.google.com/p/faculty-gwt/source/browse/trunk/examples/hellogwtwithjpa-addwidgets/src/META-INF/persistence.xml hope it helps, Hasan... http://www.jroller.com/hasant On Tue, Aug 11, 2009 at 10:04 AM, tolga ozdemir wrote: > > Hi everybody, > > I am starting to learn GWT stuff for a while.
