Menu Item and MVP
Just sharing some thoughts Would the MenuItem class need to implement HasClickHandler so that when a MenuItem is clicked, the action can be handled in the presenter. At this time, the MenuItem needs an object that implements the Command interface, so the view seems to know about the presenter. I would like to know what others think about this. - mic. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Extending widget built by UIBinder
I have a class UIPopup which is coded with UIBinder.
public class UIPopup
extends DecoratedPopupPanel
{
private static PopupUiBinder uiBinder =
GWT.create(PopupUiBinder.class);
interface PopupUiBinder
extends UiBinderWidget, UIPopup{}
@UiFactory
public UIPopup getThis(){
return this;
}
.
.
}
Then I extended UIPopup and called the class PopupWin.
public class PopupWin
extends UIPopup
{
public PopupWin(MaineWin maine){
this.maine = maine;
}
final public MaineWin maine;
}
However, GWT compilation complained of errors:
PopupWin has no default (zero args) constructor. To fix this, you can
define a @UiFactory method on the UiBinder's owner, or annotate a
constructor of PopupFrame with @UiConstructor.
There are two possibilities to my getting the error:
1. There is a mistake in my code.
2. Any class extended from UIBinder must provide a zero arg
constructor.
3. There is an undocumented UIBinder directive/annotation that can be
used to instruct that UIBinder features should not be passed on to
subclasses.
I believe the case is due to possibility #2.
If so, this is bad design on part of GWT architects.
Because a programmer using my widget library should be blind to
whether is was built using UIBinder or plain old java source coding.
There also are valid reasons when I deliberately do not want the user
of the library to have access to a zero arg constructor.
Either way it is wrong and bad practice to have the user of my library
to expect to be constrained by UIBinder.
I would like to know if the error is due to case #1, #2 or #3.
If case #2, I request such bad design policy be corrected.
If case #3, does the GWT team need my help in writing the
documentation. I am willing to donate my time because it is bad if GWT
(and other Google products) features seem to follow the early days of
Microsoft's practice of undocumented features, and you have to ask for
them in forums or insiders.

Re: New GWT widget resource, of sorts: vaadin.com/directory
Hi, this is the demo behavior or vaadin behavior which every widget will need to retrieve some data from server? It depends, as is often the case... Vaadin is server-driven, so most components communicate with the server _at some point_. But: - There is the concept of immediateness: e.g. if you have a bunch of non-immediate textfields, nothing will be sent until you press the save button (that would obviously be immediate). Almost all of the demos are immediate and provide some extra feedback, for the sake of the demo, so it will almost always send some extra stuff back and forth. Otherwise, if the state was just pushed to the server but nothing changed, only a short acknowledgement message will be returned. - You _can_ make customized client-side composites and components that communicate with each other but not with the server - this is done in plain GWT. But the main benefit with Vaadin is the server integration, so usually you would only do this if you have some very specific needs. I hope this cleared things up a little. I would recommend trying it out to see what I'm actually talking about; a small example with some buttons and textfields is really easy to make, especially with eclipse and the vaadin plugin. Anyway, questions are always welcome. Best Regards, Marc -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: New GWT widget resource, of sorts: vaadin.com/directory
Vaadin is not GWT. Vaadin makes use of GWT as the browser presentation component. There is a lot more within vaadin that is not GWT. Vaadin is a web application framework which presents and integrated perception to the programmer unifying the server and client components. Vaadin is architected with a subset of web application possibilities in mind and it is very good when used within that subset. There are too many other web applications whose architecture cannot fit into vaadin's constraints. Therefore, listing vaadin directory elements as generally useable GWT widgets would be misleading because to use vaadin widgets, you would have to use them in a vaadin application, which in turn locks you from the freedom to control your presentation and how the server communicates with the browser. Once you start with Vaadin, it is very difficult to escape out of the bounds of Vaadin's integrated server-client constraints. To many, this is an advantage, because such programmers want to see a unified picture between server and browser. However, for many who are too aware of the differences between the server and client and wish to control them separately by acquiring control of the communication process between server client, vaadin presents too many obstacles. It is difficult to use vaadin to construct a mashed application set. It is difficult to use vaadin to construct a site mashed from facebook, twitter, youtube, yahoo elements as well as under GAE constraints. It is difficult to access the http request and response objects and under GAE such is a rather painful constraint. Which means, I do not have full control of the presentation layer. Because I have to accept that the presentation layer is due to both client and server components, I have no control over the responsiveness of the presentation elements on the browser. I have been using smart-gwt with vanilla GWT as long as I ensure a clear dichotomy between smart-gwt and vanilla gwt widgets, and even succeeded in extending some smart-gwt widgets to be used within UIBinder. However, I found it really difficult in using other frameworks to work with vaadin and the process of writing wrappers did not work very well for me. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Dynamic Module Loading
Hi, I don't know if I'll answer your question but we working on a main GWT- module with pluggable sub-modules. Each sub-modules is an ui- independant part of the whole application. To avoid interferences, each module loads into its own iframe. I wrote a messaging system that allow each module to communicate with each other (JSON serialization, auto-discovery of other modules...). Olivier On 31 mar, 03:10, lineman78 linema...@gmail.com wrote: I know this is a common request of people trying to make pluggable applications. It seems that every time someone comes up with a solution to this problem the GWT team changes the way the core linkers work and break the solution. I was wondering if anyone knows a way to dynamically load a module either with a new linker, or a different method than the traditional appending a new script element to the end of the body. I try to append a script element to the end of the body and it completely blows the document away and freezes the page in a loading mode.

My pages outside of the vaadin framework is unable to access variables defined inside the framework unless I place them in memory cache or session attributes. It may be just one or two pages in every web app project, but those one or two pages that I have to create outside the vaadin framework are very crucial features required by the user. Since vaadin does not have an API to let non-vaadin components communicate with the framework, those two pages with crucial features effectively preclude me from using vaadin. For the same reason, then, vaadin does not play nice with non-vaadin components by not providing an avenue to communicate/acquire state changes to non-vaadin components. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT and GeoTools Servlet problem
Hi,
I've got a servlet which uses the GeoTools library to contact a remote
server and parse the XML, it then returns the results to the browser
client.
I've got a button on the client side which initiates the call to the
servlet. When I click this button the first time, I get an
ClassCastException. However, when I click it a second time everything
works fine!
I don't think this is a problem with GeoTools as it works perfectly
fine when I do a similar thing locally. My first assumption was that
GWT wasn't finding the necessary classes the first time around, but
had them ready for the second time. However I've added all the
required jars to my WEB-INF/lib folder and I still get the same
problem.
Something must be happening between the first and second server call
to make it work, but I don't know what it could be. Maybe GWT is
loading some required class or jar and not telling me about it?
I've included my stack trace and servlet code snippet below, although
I don't know how much use they'll be...
Any help would be appreciated.
Thanks,
Jon

Re: GWT 2.0.3 + Maven2 + Eclipse
Make sure you do a clean install of the google plugin in a clean eclipse. I tried updating the google plugin to version 1.3.2 but after the update, not all of the features in the plugin were enabled for me. I've spend a lot of time trying to get a sample project working without success. After using a clean eclipse with a clean google plugin installation (make sure you use version 1.3.2 of the plugin). The sample app ran without any problem. On 22 mrt, 21:46, Keith Platfoot kplatf...@google.com wrote: Hi Sergio, Just wanted to mention that we've just released the 1.3.1 version of the Google Plugin for Eclipse, which has much better interoperability with GWT+Maven projects. We even have a new FAQ dedicated to this scenario: http://code.google.com/eclipse/docs/faq.html#gwt_with_maven As of 1.3, it is easy to debug your Maven project's GWT code with a regular Web Application launch configuration. If you're using Eclipse for Java EE, you can also get automatic refresh when your source code or static resources (HTML, CSS, etc.) change. Unlike previous versions of the Eclipse plugin, you can now customize your project's configured WAR directory (e.g. set it to 'src/main/webapp') and specify that it should be used as input-only (per Maven convention).

Re: Menu Item and MVP
I created an EventFiringCommand class for instances like this. Basically, you put the event bus and the event to fire (or the code to generate the event) in the command. The Command should be a presenter- layer object, since it has no need to know about the view (and should be easy to unit test). Theoretically, you could just make inner classes in a Presenter for each Command you write. It all depends on how you want to organize your code and the needs of your specific project. On Mar 31, 12:07 am, mic mina...@gmail.com wrote: Just sharing some thoughts Would the MenuItem class need to implement HasClickHandler so that when a MenuItem is clicked, the action can be handled in the presenter.

How to implement hashCode() and equals() for a point in 2D-space (x,y) in GWT?
Hi,
this question might seem stupid but how can one implement hashCode()
and equals() for a simple 2d point class as follows:
public class Point {
private double fX;
private double fY;
public double getX() {
return fX;
}
public void setX(double x) {
this.fX= x;
}
public double getY() {
return fY;
}
public void setY(double y) {
this.fY= y;
}
}
The generated equals() and hashCode() methods from Eclipse do NOT work
with GWT as method Double.doubleToLongBits() is missing:
@Override
public int hashCode() {
final int prime= 31;
int result= 1;
long temp;
temp= Double.doubleToLongBits(fX);
result= prime * result + (int) (temp ^ (temp 32));
temp= Double.doubleToLongBits(fY);
result= prime * result + (int) (temp ^ (temp 32));
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (!(obj instanceof Point))
return false;
Point other= (Point) obj;
if (Double.doubleToLongBits(fX) !=
Double.doubleToLongBits(other.fX))
return false;
if (Double.doubleToLongBits(fY) !=
Double.doubleToLongBits(other.fY))
return false;
return true;
}
Does anyone have an idea how to implement this?
thanks a bunch,
Dennis

Re: How to implement hashCode() and equals() for a point in 2D-space (x,y) in GWT?
It seems that this got reverted at some point:
http://code.google.com/p/google-web-toolkit/source/diff?spec=svn2434r=2434format=sidepath=/trunk/user/super/com/google/gwt/emul/java/lang/Double.java
does anyone know why?

Hi,
this question might seem stupid but how can one implement hashCode()

public void setX(double x) {

with GWT as method Double.doubleToLongBits() is missing:
@Override

result= prime * result + (int) (temp ^ (temp 32));

At this time, the MenuItem needs an object that implements the Command interface, so the view seems to know about the presenter. I would like to know what others think about this. I've recently migrated from views with many HasXxxHandlers getters to views with a setListener method that the presenter injects into its view. The listener defines callback methods such as save(), close(), italicize(), bold(), delete(), etc. It makes unit tests waaay easier to write (you don't have to mock each HasXxxHandlers, capturing each added XxxHandler, eventually mocking the XxxEvent, etc.) and in your case would make things easier: the Command is an implementation detail of the view. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Problem using java projects in GWT
Thanks I'm gonna to try it 2010/3/30 lineman78 linema...@gmail.com You cannot use source code from a java project in GWT directly. All GWT code must be in the client path of a module. i.e. sura.ticketcheck.bo.Instancia is not part of a GWT module. There is one workaround I have gotten to work(only once, so no guarantee). 1) Create a file BoModule.gwt.xml in your source folder under the following path: sura/ticketcheck 2) Put the following text into the file: ?xml version=1.0 encoding=UTF-8? !DOCTYPE module PUBLIC -//Google Inc.//DTD Google Web Toolkit 2.0.3//EN http://google-web-toolkit.googlecode.com/svn/tags/2.0.3/ distro-source/core/src/gwt-module.dtd module inherits name=com.google.gwt.user.User / source path=bo / /module 3) In your src/ticketcheckGWT/xxx.gwt.xml put inherits name=sura.ticketcheck.BoModule/ Essentially what you are doing is tricking the GWT compiler into thinking that sura.ticketcheck has a module who's source is in the folder 'bo'. This should work as long as all files within package sura.ticketcheck.bo don't import outside of that package except standard java objects that are available through the com.google.gwt.user.User module.

Re: image help

Re: image help
You can use any image manipulation software in batch mode to process all images at one go. Alternatively, if you are serving images via servlet, you can use the java image libraries to add the watermark. If you google around, you should find a lot of ways to add a watermark to multiple images in one go. --Sri On 31 March 2010 20:36, Chris thechris...@gmail.com wrote: Is it possible to lay a watermark Image on top of the image I already have on my page or do I have to edit each photo in Photoshop or something like that to lay a watermark over it?

Re: Dynamic Module Loading
Yeah, there is 1 problem I have with your solution and a separate issue your solution doesn't address. The problem I have with your solution is that iFrames can't inherit size. One behavior I like is that you can stack the modules and they will fit tightly against the other and the one below will move if the upper one's height changes, i.e. a disclosure panel. The issue that your issue doesn't seem to resolve is that I would like to dynamically add the modules to the page as they are added and would like the main module to not know anything about them other than the fact that they extend an abstract sub module and the location of the module's nocache.js.

I try to append a script element to the end of the body and it completely blows the document away and freezes the page in a loading mode. I found an email exchange between members of the GWT contributors group in December where they discuss new methods for the default linkers using dynamic iframes. I have been exploring this capability since 1.5 and every time I revisit it the method(hack job) I used the last time will not work. I would really like a more consistent method. Every forum I have seen where someone asks this someone inevitably asks why, so let me head off this question by explaining. I have run into this in a few different situations, one when trying to integrate GWT portlets into Liferay(Java portlet). The second situation is in trying to create a dynamic binding of sorts. I have been trying to figure out a way to create a GWT portal where you could install modules and they could be added and removed dynamically without having to recompile the core, creating something similar to iGoogle or Liferay in a GWT/J2EE implementation. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Problem using java projects in GWT
In our projects, we just use our source code path directly.
When launching the project in DevMode from within Eclipse, the launch
config's classpath contains both the default classpath plus the /src
directory.
When compiling the project in Ant, we reference the source path
directly in the gwt Compiler call:
java classname=com.google.gwt.dev.Compiler fork=true
maxmemory=512M failonerror=true
arg line=-war ${temp.war} /
arg value=com.x.ModuleName /
classpath
path location=src /
path location=${temp.classes}/
/classpath
/java
Basically, the GWT Compiler needs both the compiled code and the
source code to successfully compile the module.
Hope that helps.

You cannot use source code from a java project in GWT directly. All
GWT code must be in the client path of a module. i.e.
sura.ticketcheck.bo.Instancia is not part of a GWT module. There is
one workaround I have gotten to work(only once, so no guarantee).
1) Create a file BoModule.gwt.xml in your source folder under the
following path: sura/ticketcheck
2) Put the following text into the file:
?xml version=1.0 encoding=UTF-8?
!DOCTYPE module PUBLIC -//Google Inc.//DTD Google Web Toolkit

module
inherits name=com.google.gwt.user.User /
source path=bo /
/module
3) In your src/ticketcheckGWT/xxx.gwt.xml put inherits
name=sura.ticketcheck.BoModule/
Essentially what you are doing is tricking the GWT compiler into
thinking that sura.ticketcheck has a module who's source is in the
folder 'bo'. This should work as long as all files within package
sura.ticketcheck.bo don't import outside of that package except
standard java objects that are available through the
com.google.gwt.user.User module. I have run into this several times
and sometimes you just have to rewrite(copy and paste) stuff into a
GWT project.

Re: Eclipse JavaEE tools + GWT Development mode
Hi David, I haven't tried the same setup with Tomcat yet, but I expect it should be the same procedure: In the Servers view in Eclipse, select the server you deployed the EAR to. Right-click it and choose Debug. This allows you to set breakpoints in your server side code. To debug the client side code, you can additionally start your GWT code server (the one that's usually on port 9997) in Debug mode (Select your GWT project, then Debug As... Web Application). You should actually modify that debug configuration to uncheck the checkbox Run built-in server! (Because you're using Tomcat instead of the built-in Jetty). Now you'll only start the code server, without Jetty. Then, if you're using default values for your ports, you can browse your application with something like: http://127.0.0.1:8080/MyProject.html?gwt.codesvr=127.0.0.1:9997 (instead of http://127.0.0.1:/MyProject.html?gwt.codesvr=127.0.0.1:9997) HTH Chris PS I'd really be interested, if it works with Tomcat, too - please report back.

Re: Is client side Javascript code always visible?
Of course, anything sent to and rendered/run by the client's browser can be retrieved by the user.

Yes. JS can be copied easily.

Re: Is client side Javascript code always visible?
If the JavaScript should be executed in the browser (as usual), then it will have to be downloaded to the browser. This means, that it can also be copied. GWT offers an option to obfuscate the generated code, and one of the effects of this is, that it's harder for someone to read the code. But it could still be copied. So, if you have some proprietary algorithms, you might want to run them on the server.

Re: Dynamic Module Loading
GWT's architecture is orthogonal to your requirement of dynamic module loading / pluggable sub-modules, so whatever solution you find will be a hack and not maintainable. One of the core philosophies of GWT - *If something can be done at compile time, do it*. The key benefit of such a philosophy is performance. GWT scores over a lot of other frameworks because of its monolithic, closed-world compile. Any framework for dynamic module loading needs to defer a few operations to runtime, and that is a cost GWT core is unwilling to pay (thats what I understand). Having said that, you can still achieve what you want. Define an API (in terms of javascript methods) for your module, and use GWT Exporterhttp://code.google.com/p/gwt-exporter/to export the methods. That way, your GWT modules can inter-operate with hand-written javascript or with other pre-compiled GWT code. You can also dynamically add new modules to a page if you wish to do so. Any shared/common will however get download multiple times as part of each modules nocache.js + guid.cache.html, and there is nothing you can do about it. --Sri On 31 March 2010 21:48, lineman78 linema...@gmail.com wrote: Yeah, there is 1 problem I have with your solution and a separate issue your solution doesn't address. The problem I have with your solution is that iFrames can't inherit size. One behavior I like is that you can stack the modules and they will fit tightly against the other and the one below will move if the upper one's height changes, i.e. a disclosure panel. The issue that your issue doesn't seem to resolve is that I would like to dynamically add the modules to the page as they are added and would like the main module to not know anything about them other than the fact that they extend an abstract sub module and the location of the module's nocache.js.

I try to append a script element to the end of the body and it completely blows the document away and freezes the page in a loading mode.

Posted issue http://code.google.com/p/google-web-toolkit/issues/detail?id=4805. As for equals, why not just compare the double values directly, vs bitwise equality? Unless you're concerned with the various versions of NaN and infinity this should work fine; in fact you might even want to allow a bit of a margin to deal with rounding. jchimene, you'd want to do something like the original poster to avoid that, 31*hashOfpX + hashOfpY.

Don't have a constructor with arguments, only use Set/Gets.

Fix the constructor and verify Kontakt is serializable and it should

What are the fields of the Kontakt class? Based on the error, one of the fields under Domain is a JavaScriptObject, but nothing in your Domain class above seems to be.

Your WAR directory (you'll have just one) will be the WebContent directory of TestWeb. Dynamic Web projects are configured to use the configuration and resource files (web.xml, HTML, CSS, JS, etc.) from this directory to build your WAR when debugging locally or creating a .war file for deployment. BTW, the default name is WebContent, but this can be customized during the New Dynamic Web project wizard. Your GWT code (in TestUI) will need to integrate into TestWeb's WAR directory when you run/debug locally and when you build a .war file. For running locally, you just need to tell GWT DevMode to run within the context of TestWeb's staging WAR directory (see steps 11 and 12 in my checklist). You don't need to copy any files manually, because GWT will pick up all the .java and .gwt.xml source files it needs directly from the launch classpath. So there really is no explicit link to TestWeb from TestUI. The only link from TestWeb back to TestUI is that your HTML host page in TestWeb's WebContent directory will need to reference your GWT module's bootstrap script (the TestUI.nocache.js file, which GWT will automatically insert into your staging WAR directory when you launch dev mode).

Re: GEP 1.3 : com.google.gdt.eclipse.suite.* packages not exported

Re: Dynamic Module Loading
I agree with everything you have said and this is the approach I am experimenting with except for one problem. Since 2.0 it is not possible to load modules dynamically. I have written a jsp that will add all the installed plug-ins' scripts to the head when the page is loaded, but unfortunately this causes a lot of unnecessary start-up loading. I am going to look into putting the entire instantiation under a runAsync and that should hopefully fix the problem. It would still be nice to load the modules dynamically, but i guess it isn't a huge deal to make them reload after installing a plug-in. On Mar 31, 12:12 pm, Sripathi Krishnan sripathikrish...@gmail.com wrote: GWT's architecture is orthogonal to your requirement of dynamic module loading / pluggable sub-modules, so whatever solution you find will be a hack and not maintainable. One of the core philosophies of GWT - *If something can be done at compile time, do it*. The key benefit of such a philosophy is performance. GWT scores over a lot of other frameworks because of its monolithic, closed-world compile. Any framework for dynamic module loading needs to defer a few operations to runtime, and that is a cost GWT core is unwilling to pay (thats what I understand). Having said that, you can still achieve what you want. Define an API (in terms of javascript methods) for your module, and use GWT Exporterhttp://code.google.com/p/gwt-exporter/to export the methods. That way, your GWT modules can inter-operate with hand-written javascript or with other pre-compiled GWT code. You can also dynamically add new modules to a page if you wish to do so. Any shared/common will however get download multiple times as part of each modules nocache.js + guid.cache.html, and there is nothing you can do about it. --Sri On 31 March 2010 21:48, lineman78 linema...@gmail.com wrote: Yeah, there is 1 problem I have with your solution and a separate issue your solution doesn't address. The problem I have with your solution is that iFrames can't inherit size. One behavior I like is that you can stack the modules and they will fit tightly against the other and the one below will move if the upper one's height changes, i.e. a disclosure panel. The issue that your issue doesn't seem to resolve is that I would like to dynamically add the modules to the page as they are added and would like the main module to not know anything about them other than the fact that they extend an abstract sub module and the location of the module's nocache.js.

I try to append a script element to the end of the body and it completely blows the document away and freezes the page in a loading mode. I found an email exchange between members of the GWT contributors group in December where they discuss new methods for the default linkers using dynamic iframes.

Re: Problem using java projects in GWT
I think the 2 of us are answering different questions. I believe the
problem he is having is that the GWT compiler is not allowing him to
use objects from a previous Java project he had done(I am assuming it
has some algorithms or POJOs that he doesn't want to replicate). The
GWT compiler won't allow you to reference these objects even if they
are in the classpath because they are not part of an included module.
Your responses assume his problem is a classpath problem, but eclipse
would be yelling at you for that one, not just the compiler. Also,
Lucas I forgot to mention, my approach will still not work if the
source(*.java) files are not in your classpath as the GWT compiler
requires the uncompiled source.
On Mar 30, 9:33 pm, Neil neiltol...@gmail.com wrote:
In our projects, we just use our source code path directly.
When launching the project in DevMode from within Eclipse, the launch
config's classpath contains both the default classpath plus the /src
directory.
When compiling the project in Ant, we reference the source path
directly in the gwt Compiler call:
java classname=com.google.gwt.dev.Compiler fork=true
maxmemory=512M failonerror=true
arg line=-war ${temp.war} /
arg value=com.x.ModuleName /
classpath
path location=src /
path location=${temp.classes}/
/classpath
/java
Basically, the GWT Compiler needs both the compiled code and the
source code to successfully compile the module.
Hope that helps.

You cannot use source code from a java project in GWT directly. All
GWT code must be in the client path of a module. i.e.
sura.ticketcheck.bo.Instancia is not part of a GWT module. There is
one workaround I have gotten to work(only once, so no guarantee).
1) Create a file BoModule.gwt.xml in your source folder under the
following path: sura/ticketcheck
2) Put the following text into the file:
?xml version=1.0 encoding=UTF-8?
!DOCTYPE module PUBLIC -//Google Inc.//DTD Google Web Toolkit
2.0.3//EN http://google-web-toolkit.googlecode.com/svn/tags/2.0.3/
distro-source/core/src/gwt-module.dtd
module
inherits name=com.google.gwt.user.User /
source path=bo /
/module
3) In your src/ticketcheckGWT/xxx.gwt.xml put inherits
name=sura.ticketcheck.BoModule/
Essentially what you are doing is tricking the GWT compiler into
thinking that sura.ticketcheck has a module who's source is in the
folder 'bo'. This should work as long as all files within package
sura.ticketcheck.bo don't import outside of that package except
standard java objects that are available through the
com.google.gwt.user.User module. I have run into this several times
and sometimes you just have to rewrite(copy and paste) stuff into a
GWT project.

Compiling against Gin in Repository fails
Hi I'm having a strange issue here... If I use the Gin jar from the central maven repository, my GWT compilation fails. However, if I use a version that I downloaded previously (unfortunately not marked as far as I could see! :( ), then everything works fine. Obviously, I'd quite like to be using the maven repository version...

Do you reckon this is a bug with Gin/GWT compile? Or perhaps I'm missing something? Any ideas how I can go forward?

Re: Menu Item and MVP
Thomas, I've heard of your approach before, but I'm not clear on the implementation... are you passing the presenter itself into the view? or are you passing instances of event handlers? The difference seems trivial, but in practice (as I imagine it, anyway) seems large: http://etherpad.com/sIAaiCfuiG Let me know what you think. I would assume the first way is what your referring to in your comment above, which implies that it is a View layer responsibility to deal with HandlerRegistrations and the like. Is that correct?

The listener defines callback methods such as save(), close(), italicize(), bold(), delete(), etc. It makes unit tests waaay easier to write (you don't have to mock each HasXxxHandlers, capturing each added XxxHandler, eventually mocking the XxxEvent, etc.) and in your case would make things easier: the Command is an implementation detail of the view. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to implement hashCode() and equals() for a point in 2D-space (x,y) in GWT?

Does this say that Point(2.0,0.0) and Point(0.0,2.0) have the same
hashCode()?
Yes, but this sort of thing is inevitable. You can't map two doubles
onto one integer without some duplication.
But that doesn't matter. Consider this hashCode() implementation:
public int hashCode() { return 0; }
This will work in all circumstances. It fulfills the hashCode contract,
it just doesn't make a HashMap with Point keys perform very well. Even
then, if you only have very small maps, this won't matter. My point is
that you shouldn't get too hung up on how this is implemented - just use
something fast and simple.

Re: Is client side Javascript code always visible?
No, it's not. The browser will see it, and so will your users if they do view-source. As the previous answers have noted, GWT optionally obfuscates JS code (i.e., makes it smaller, less readable), but that is done largely for performance purposes (the smaller your JS code, the less you have to download, the faster your app will be), not for hiding it from the user. There are tools that undo obfuscation. In other words, anything secret/prorietary should run on the *server*-side of your application. This, by the way, goes for all JS/AJAX apps and is not particular to GWT. kathrin On Wed, Mar 31, 2010 at 1:58 PM, NeuroPulse neuropu...@gmail.com wrote: What I mean is, is it compiled like C++ is compiled into a program?

Re: GWT/Hibernate/Oracle/Eclipse
It sounds like you're using a class that is not supported by AppEngine. But it also sounds like you don't want to use AppEngine ( http://code.google.com/appengine/) in the first place, because you have your own oracle database. I don't know what you mean by start the Google App Engine in eclipse, but what you probably want is to do debug/run as - Web Application, which starts development mode, which lets you debug a GWT application. Then, when you want to deploy it, you have to compile the GWT application (from Java to JavaScript), which you can do in eclipse under Google- GWT Compile. (Note that you then have to put the resulting js files from the war directory into the correct place on your server to be able to see them in the browser). If you *are* trying to use AppEngine, it's a different story. It doesn't look like you can make Hibernate work in AppEngine right now (from http://groups.google.com/group/google-appengine-java/web/will-it-play-in-app-engine ): *Hibernate* Versions: All Status: *INCOMPATIBLE* - You cannot currently use Hibernate directly. The differences between the App Engine datastore and SQL were too great to get the standard Hibernate up and running under App Engine. App Engine does support JDO and JPA, so you may be able to convert your Hibernate code to use one of these ORM interfaces. kathrin On Wed, Mar 31, 2010 at 6:19 AM, bebauer1200 be.ba...@gmx.at wrote: Hello, please, can anyone help me?

Diagnosing serializable class compilation issues.
Imagine your favorite statically compiled language's compiler treated certain classes of statically determinable semantic errors differently than normal. Instead of erroring out with a useful message, the compiler simply injects code in the offending location that will cause an error at runtime. The runtime error will not provide a useful stack trace, nor will it provide any information to the cause of the error. Now imagine that your compiler take several minutes to compile your program, so that when you encounter the error at runtime you have to guess what went wrong at compile time, modify your code, recompile, and after several minutes re-run your application to see if the error is still present. Such a compiler would be ludicrous, yet this appears to be exactly what the GWT compiler does. It knows that I as a user marked a particular class as IsSerializable. It knows that I am using this class as part of an RPC interface. It knows that it will not or cannot actually compile code to serialize the object at runtime. And yet, the compiler moves on and compiles the code in such a way that a useless error message will display at runtime when the RPC is invoked. Even if I set the log level to ALL, I get no information from the compiler's output that I couldn't get by inspecting the produced gwt.rpc whitelist file manually. Why does the gwt 2.0 compiler not error out automatically with a useful message in this scenario? I can't think of any situation where the current behavior is desirable. Also, why is no useful diagnostic information ever given when the scenario occurs even with full logging enabled? I have searched the Internet for a long time for an answer to this and have not found an answer. I have also wasted a significant number of hours playing a guessing game when my classes aren't serializable. I feel like every time I create a new RPC, after potentially hours of painful debugging I find a new reason for the gwt compiler to fail silently. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: UIBinder and IE6
I believe Google has begun to transition away from IE6 support, though, I don't think UiBinder is incompatible with IE6 at all. If you read the documentation it explains quite well what doctypes to use. From what I gather, GWT is for eliminating inconsistencies between browsers in a way that the developer doesn't have to worry about whether or not their app will run on IE6/7/8, among other things.

Re: Menu Item and MVP
I've been looking into this for a chapter in the new edition of GWT In
Action, here's where I'm at.
The Google I/O approach to MVP has never sat well with me because, apart
from the fact that the interface can get out of hand, it just seems wrong
that the interface specifies that the view must, say, have something
clickable and not leave the implementation to the view.
So what I'm playing about with right now is (for the example you gave).
There would be a couple of interfaces HasClose and HasSave which would be
along the lines of
public interface HasSave
{
void save();
}
There would be a couple of corresponding CloseHandler and SaveHandler
classes e.g.
class SaveHandler implements ClickHandler
{
private HasSave presenter;
public SaveHandler(HasSave presenter)
{
this.presenter = presenter;
}
@Override
public void onClick(ClickEvent event)
{
presenter.save();
}
}
The presenter looks like this
class Presenter implements HasSave, HasClose
{
View view;
public Presenter(View view)
{
this.view = view;
}
@Override
public void save()
{
view.setText(Save);
}
@Override
public void close()
{
view.setText(Close);
}
}
and the view like this
class View extends FlowPanel implements HasText
{
Label label = new Label();
public View()
{
Presenter presenter = new Presenter(this);
add(new Button(Open, new SaveHandler(presenter)));
add(new Button(Close, new CloseHandler(presenter)));
add(label);
}
@Override
public String getText()
{
return label.getText();
}
@Override
public void setText(String text)
{
label.setText(text);
}
}
in the AppController or onModuleLoad method, you'd just have the line
RootPanel.get().add(new View());
Does that make sense? Feel free to ask but I'm still not too far forward
with this approach yet.
For a tiny project, it's a bit of work (unless you have already written the
interfaces and handler classes for some other project) but it does keep
everything well organised in larger projects.

Thomas,
I've heard of your approach before, but I'm not clear on the

or are you passing instances of event handlers? The difference seems
trivial, but in practice (as I imagine it, anyway) seems large:
http://etherpad.com/sIAaiCfuiG
Let me know what you think. I would assume the first way is what your
referring to in your comment above, which implies that it is a View
layer responsibility to deal with HandlerRegistrations and the like.
Is that correct?

Just sharing some thoughts
Would the MenuItem class need to implement HasClickHandler so that
when a MenuItem is clicked, the action can be handled in the
presenter. At this time, the MenuItem needs an object that implements
the Command interface, so the view seems to know about the presenter.
I would like to know what others think about this.
I've recently migrated from views with many HasXxxHandlers getters to
views with a setListener method that the presenter injects into its
view. The listener defines callback methods such as save(), close(),
italicize(), bold(), delete(), etc.
It makes unit tests waaay easier to write (you don't have to mock each
HasXxxHandlers, capturing each added XxxHandler, eventually mocking
the XxxEvent, etc.) and in your case would make things easier: the
Command is an implementation detail of the view.
