It can't know what name you put in there. 2. is the resultant stub as thus created threadsafe or is their any kind of restrictions of its being used simultaneously i.e can i save a reference of the stub as a static variable and call it from anywhere in my code ??

Maven versus Cypal
Hi, I started using GWT around a year ago and I used Cypal plugin in Eclipse. I now found out that there is another plugin that is used for SmartGWT which is called Maven. What's the difference between them? Should I switch to Maven or I can continue my work with Cypal?

call to JSNI randomly fires Object doesn't support this property or method
Hi I declared a native method
public native void defineBridgeMethod(ModelHandler modh) /*-{
$wnd.computeLoanInterest = function(amt) {
mo...@com.dhc.dhcvision.ui.client.modelhandler::computeLoanInterest(I)
(amt);
}
}-*/;
and build in in my application by calling
ModelHandler modH = new ModelHandler();
defineBridgeMethod(modh);
ModelHandler class looks like this:
public class ModelHandler {
public void computeLoanInterest(int amt) {
MessageBox.alert(String.valueOf(amt) + inner);
}
}
I call the native method in html javascript like that:
parent.computeLoanInterest(5);
The first time I called the native method from javascriptside
everything works fine but now after a while I always get an error
message Object doesn't support this property or method. It seems
that the mentioned 'object' is the ModelHandler instance because the
javascript error is pointed to line 2 which is position of the call of
the ModelHandler instance in the native method declaration.
Any idea why it works in the beginning and what could happened that it
does not work anymore? I always test these stuff in Hosted Mode.
Thx.

But there are a number of good cache implementations out there doing it for you: http://java-source.net/open-source/cache-solutions http://www.vipan.com/htdocs/cachehelp.html The advantage is that it allows a same ticket to be shared amongst sessions (a browser and a download manager for instance) in some circumstances (that *you* control; the cases where you don't want such sharing being protected using anti-CSRF techniques).

GWT Portlets framework published
GWT Portlets is a free open source web framework for building modular GWT (Google Web Toolkit) applications. GWT provides the low level building blocks required to build web applications (Java to Javascript compiler, basic UI widgets, an RPC mechanism etc.) but typical business applications can benefit from the additional scaffolding provided by GWT Portlets. In traditional web applications this role would be fulfilled by Struts and other web frameworks. http://www.gwtportlets.org/ Please have a look. All feedback will be appreciated. Note that the signup mails send by the site tend to get eaten by spam filters so check your spam folder if you don't receive the mail.

Re: A thought about GWT project structure
If you're referencing server-only code from the client, then you have a fundamental problem in what you're trying to do. Same if you're referencing a Widget from the server. Your developers should already know that. If they don't, they need to be educated anyway. It's not rules and tricks but rather right and wrong ways to build an app. The wrong way is to mix client side and server side in one single project. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

What I want is: o Just 1 JAR distributed by me. o Code for optional library in separate JAR distributed/maintained by others o Users of my library don't have to physically mess with the optional JAR (no need to download it, place it on build path, or add an inherits clause) if they don't use those optional features in their code. Ideally, my code might even somehow check if the optional library is available. If so, it uses it, otherwise it uses the built-in fallback. But it would be OK if the developer using my library would just tell it if the optional library is to be used or not. Can't you put those optional features into another module that developers would only inherit if they want to (and thus would have to pull the third-party JAR and put it in the classpath only when opting- in)? If you don't want (or can't, for whichever reason) separate the optional features in a distinct module, than you can use deferred- binding; and opting-in could be either: - inheriting another module containing the appropriate replace-with mappings - setting a property (set-property) to a specific value (this property having been set to a default value in your module) which would trigger different replace-with rules (all in the same module), e.g. your module contains (along with all the needed generate-with mappings) define-property name=use.optional.features values=true,false/set-property name=use.optional.features value=false/, and the developer opts in by adding this line to his module: set-property name=use.optional.features value=true/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Hi, The query formed with comma through sendRequest method of RequestBuilder results in 500 internal server error. For instance consider the following query, test.do?param1=oneparam2=test,withcomma. Above URL when posted results in 500 error. I tried using encodeURI and encodeURIComponent APIs of javascript but in vain. Please clarify the following, 1) Is comma a reserved character in GWT ? 2) If question 1 answers yes, how should we handle the same ? Is there any API in GWT to handle it or should we write a customized solution .?? Please clarify ASAP.

applet class not found
hi,
when i use a html-page with this applet-tag:
APPLET CODE = applet.MosaicUploader ARCHIVE = ../applet/
MosaicUploader.jar WIDTH = 50 HEIGHT = 50
Here is the MosaicUploader Applet
/APPLET
the applet is displayed. But if i use the same html in a widget
public class MosaicUploaderAppletWidget
extends Composite
{
public MosaicUploaderAppletWidget()
{
if( GWT.isScript() ) {
initWidget( getAppletHTML() );
}else{
initWidget( new Label( MosaicUploaderMock for embeded
mode ) );
}
}
private HTML getAppletHTML()
{
StringBuilder sb = new StringBuilder();
sb.append( applet code=\applet.MosaicUploader\ codebase=\../
applet/MosaicUploader.jar\ width=50 height=50 );
sb.append( Here is the MosaicUploader Applet );
sb.append( /applet );
return new HTML( sb.toString() );
}
}
the java-console of firefox shows this class not found exception:

Re: Problem with GWT Widget Printing

How about replacing DeferredCommand.add(printFrameCommmand); which is

We will jump directly to 1.6. The Print class boil down to :
public static void it(String html) {
try {
buildFrame(html);
DeferredCommand.add(printFrameCommmand);
} catch (Throwable exc) {
Window.alert(exc.getMessage());
}
}
public static void it(String style, String it) {
it(htmlhead+style+/head\nbody+it+/body/
html);
}
I did that so we could print both DOM elements and strings.
Perhaps I should treat DOM elements diferently adding them to the DOM
instead
of using the toString method? Anybody know if this will render faster
and/or more

Jay, does this work for both 1.4 and 1.5 or it'll only work on 1.5?

Re: GWT import external jar
That is correct, if your external library is only used on the server side (Hibernate, axis, etc) then there is no need to reference it in your gwt.xml file. However, if you do need to use it in your client code then it must contain source (.java files) as well as have a gwt.xml file of its own, AND be translatable (not something that your average java lib is) -jason On Apr 4, 2009, at 7:18 AM, Qing wrote: You mean I don't need to add inherits name='FinancialFookit'/ to the OnlineBanker.gwt.xml?

Re: How to get internal widget to notify its parent widget when clicked (and have the parent execute something)
the easiest way is to create a click handler that holds a reference to
the parent
the simplest form would look something like:
myWidget.addClickHandler(new ClickHandler(){
public void onClick(ClickEvent event){
parent.doSomething();
}
});
no need to do any sink/unsink mucking about.

Re: GWT for Solaris
The GWT compiler should run just fine on any OS with a Java 1.5 JDK. the compiled code should run on any supported browse (no matter what the OS ... for instance it works fine on android and iPhone) As for the Hosted mode, well that is pretty much de-emphasized as it will be replaced with OOPHM in GWT 2.0, so I seriously doubt you'll gain any traction in getting someone to develop a solaris specific version. You could try using the OOPHM version in SVN and see how that works for you.

Re: Runasync feature of GWT
I haven't switched to the trunk for this yet, but I can tell you that I positively must start using runAsync soon. My site (langolab.com) has over 100kb of gzipped monolithic gwt javascript at this point, and it's growing quickly.

Re: A thought about GWT project structure
Nothing says that you do. But you will want to then have at least a 3rd project that contains the common types shared between client server.

Re: iText Causing GWT-RPC callback to fail. Need to send to HttpServletResponse?
You can't send a PDF (or any other binary blob) to a GWT app over RPC. Well, you can, but you can't do anything useful with it on the client. You need to switch back to traditional servlets behind traditional URLs. It's the same problem as serving images over RPC and that's been discussed here before.

Re: iText Causing GWT-RPC callback to fail. Need to send to HttpServletResponse?
you are unlikely to get the pdf back from an RPC in any useful form.
The RPC mechanism is expecting a particular format, and manually
mucking about with the response object is going to upset that
expectation. Even if you did manage to get the bytes back via the
RPC's XHR, what would you plan on doing with them?
basically, what you want to do is either use a form post to supply the
generation parameters and target a new window where the receiving
servlet could send the generated PDF, or use a 2 request system where
you send your RPC with the parameters and cause the PDF to be
generated, then a second request (new Window using a get request) to

Generating the PDF is not a problem. I can generate one and write it
to a file on the server without any trouble. However, I am having
trouble presenting the user with it (I would rather NOT write them to
files on the server, and just let the user save on their own machine
if they wish to do so).
Here is code for a sample Hello World
public boolean generatePDF(ReportDO report, int id) {
System.out.println(hello world to follow);
// get request
//HttpServletRequest request = getThreadLocalRequest();
// get response
HttpServletResponse response = getThreadLocalResponse();
Document document = new Document();
// generate test PDF
try {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
//PdfWriter.getInstance(document, new FileOutputStream
(HelloWorld.pdf));
PdfWriter.getInstance(document, baos);
document.open();
document.add(new Paragraph(hello world));
document.close();
// setting some response headers
response.setHeader(Expires, 0);
response.setHeader(Cache-Control, must-revalidate,
post-check=0,
pre-check=0);
response.setHeader(Pragma, public);
response.setContentType(application/pdf);
// content length is needed for MSIE
response.setContentLength(baos.size());
// write ByteArrayOutputStream to ServletOutputStream
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);
out.flush();
}
catch (Exception e) {
System.out.println(generatePDF:Exception +
e.getMessage());
}
return true;
}
This code is in my GWT-RPC Servlet, which extends
RemoteServiceServlet. Note if I use the currently commented line of
FileOutputStream(HelloWorld.pdf) it will generate the file and work
fine. However, if I try to send it to the browser, nothing appears,
and the AsyncCallback for GWT-RPC calls the onFailure() method.
Does anyone know where the problem might be? I'm assuming it has to
do with response. RemoteServiceServlet has a method
getThreadLocalResponse() which returns HttpServletResponse, which is
what the iText examples use. I know very little about these response
objects. But it seems that somehow there is some interference between
that and GWT-RPC. The AsyncCallback is a success when writing to
file. However, when attempting to send to browser, it fails.

Re: opening new page
In general, you need a module file (.gwt.xml) for each GWT module (anything with onModuleLoad()). Perhaps it would be best at this point if you posted your code and described in more detail what you're doing. Which GWT version? Are you testing in hosted mode? With the embedded server?

Also, you must do one of these things: ... b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. As GWT complies with section 6 (and is a work that uses the library), using option b (note it says you must do one of these things, not all of these things), there is no requirement they make an offer for source.

Re: iText Causing GWT-RPC callback to fail. Need to send to HttpServletResponse?
There is a PDF generation demo using a GWT entrypoint on the DynamicJasper
website (a wrapper for Jasper, which I think still uses iText deep inside).
http://dynamicjasper.sourceforge.net/
Anyway you can look at the relevant servlet code there, and the hand-off
from the GWT run report button.

Re: How to check a login
Please look at the tutorial
http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5s=google-web-toolkit-doc-1-5t=GettingStartedRPC.
That should hopefully clear things up.
There's two parts to the RPC (although 3 classes).
Async - the client side class that serializes the objects sends out a
request to the server.
Impl - the server side class that gets called when the request is received
deserialized. it then returns at which point the result gets serialized
sent back.
At this point, the callback given to the async invocation on the client side
is invoked with the result.
So on the client side, no references to the service implementation. 1 call
to the async is enough
On a side note, I dunno about what the recommended best practices are for
GWT, but I prefer to throw a custom exception instead of returning null
(that way onSuccess always has valid data onFailure is responsible for
handling failure).
Also, I recommend you provide template parameters for your AsyncCallback
(makes your code neater so you don't have explicit casting everywhere).
i.e. AsyncCallbackSerializableUser... onSuccess(SerializableUser user)
So mainly, just delete the lines:
LogonServiceImpl logservice = new LogonServiceImpl();
user = logservice.checkLogin(login, pass);

Re: Starting Hosted Mode leads to java.lang.UnsatisfiedLinkError (Unable to load Mozilla for hosted mode)
Hi Steffen, Make sure that you have the libstdc++5 installed on your machine. Other developers who have experienced this issue found out that they were missing the library, or had a different version of the library installed (e.g. libstdc++6). Also, you might want to verify that the permissions are correctly set on the .so to make sure the hosted mode process can access it on startup. If you're using Debian, the following command may help: sudo apt-get install libstdc++5 Hope that helps, -Sumit Chandel On Tue, Mar 31, 2009 at 1:15 PM, stsch stsc...@schliwinski.de wrote: If I try to run the samples or a newly created GWT application in Hosted Mode I get the following error: ** Unable to load Mozilla for hosted mode ** java.lang.UnsatisfiedLinkError: /home/steffen/Desktop/gwt-linux-1.5.3/ mozilla-1.7.12/libxpcom.so: libstdc++.so.5: cannot open shared object file: No such file or directory at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1767) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1663) at java.lang.Runtime.load0(Runtime.java:787) at java.lang.System.load(System.java:1022) at com.google.gwt.dev.shell.moz.MozillaInstall.load (MozillaInstall.java:190) at com.google.gwt.dev.BootStrapPlatform.init(BootStrapPlatform.java: 49) at com.google.gwt.dev.GWTShell.main(GWTShell.java:354) My OS is Ubuntu 8.04 (Hardy Heron).

Re: MenuBar Submenu Remove Border
Wow - you can't even install a firefox plugin? That sucks. But even still, you could have manually iterated over the DOM (or used DOM.toString() at the appropriate time to get the DOM structure at a specific point in time). All widgets have a getElement method that returns the DOM element.

Re: iText Causing GWT-RPC callback to fail. Need to send to HttpServletResponse?
Thanks for all the responses. I had (and still do) little
understanding of responses and requests as I rarely work directly with
them. However, I now see that GWT-RPC is not the way to go. From
what I've read and what I saw using Firebug, GWT-RPC sets up the
response variable for it's own purposes as part of GWT-RPC, so by
going in and modifying it myself I caused problems with GWT-RPC.
Instead of extending RemoteServiceServlet, I extended HttpServlet and
have been able to get a result. However, I was not able to get a
result from the GWT app yet using RequestBuilder. I attempted to do
so, and the function ran (I had some print statements which showed up
in the log) successfully and the RequestCallback received a response.
However, nothing happened.
Is it possible to do this using RequestBuilder? Using Firebug, I saw
a response was generated and it seemed to have the correct headers as
I had set. However, no PDF file opened, was offered, etc. and it
appeared as if nothing happened.
I was able to get it to generate a PDF by simply typing the URL into
my browser...
www.site.com/app-name/PDFServlet
that URL displayed a Hello World example PDF as expected. Ideally,
this would open by clicking from GWT app. I suppose I could create a
standard HTML link in the GWT app and that may work, but I wonder why
the RequestBuilder did not work, even though response was returned.
And finally - does anyone have any tips on ways to make it more secure
somehow? While there is a rare chance, and it probably wouldn't be
anything serious, anyone could type in the URL in the browser and view
the reports that will be generated, provided they pass in the report
ID, etc. Is there a way that it would only work if accessed from the
app (which is user protected) or are there any other tips on making it
a bit more secure?
Below is my current servlet code, followed by the RequestBuilder part
of the app that failed to work as expected.
public class PDFServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse
response) throws IOException, ServletException {
System.out.println(Hello World! to follow);
Document document = new Document();
// generate test PDF
try {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
//PdfWriter.getInstance(document, new FileOutputStream
(HelloWorld.pdf));
PdfWriter.getInstance(document, baos);
document.open();
document.add(new Paragraph(Hello World!));
document.close();
// setting some response headers
response.setHeader(Expires, 0);
response.setHeader(Cache-Control, must-revalidate,
post-check=0,
pre-check=0);
response.setHeader(Pragma, public);
response.setContentType(application/pdf);
// content length is needed for MSIE
response.setContentLength(baos.size());
// write ByteArrayOutputStream to ServletOutputStream
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);
out.flush();
}
catch (Exception e) {
System.out.println(PDFServlet::doGet::Exception +
e.getMessage
());
}
}
}
/*
* Code in GWT app - ultimately I will pass report type, ID to the
servlet to generate the
* appropriate report
*/
public void onRecordClick(RecordClickEvent event) {
//need to add report ID, etc. to the request in
the future
RequestBuilder request = new
RequestBuilder(RequestBuilder.GET,
PDFService);
request.setCallback(new RequestCallback() {
public void onError(Request request,
Throwable exception) {
SC.say(onError); // this is

Re: How to get internal widget to notify its parent widget when clicked (and have the parent execute something)

at different levels.
Currently i am using a VERY dodge way of this.getParent().getParent

Hi Brandon,
I'm not clear why you would need to compile the sub modules independently
from the main module. The GWT compiler performs a monolithic compilation for
each module it compiles, therefore the submodules would be completely
independent from the main module if they were compiled separately. It seems
like if you want to reuse those submodules, the best way would be to
reference them from your main project (linking source in Eclipse, for
example), and adding the submodules to your main GWT compilation target as
shown in the ant snippet.
If you have server-side classes that you want to compile separately and
include in the main project, you should probably set up a build target that
will javac those classes and copy them over to the main GWT project
directory. The gwtc target would then be dependent on that step before being
able to perform its own GWT compilation.
Putting into context of your next goals, 3. would be solved by what was
described in the last paragraph. 1. and 2. might not need to be explicit
goals since compiling separately probably won't be of much value for what I
think you're trying to do. Although I may have misundertstood the purposes
for goals 1 2.
Hope that helps,

Hi Brandon,
I think the typical way to reuse an existing GWT module in another is to
package that module into a JAR file (source included) and then refer to
the
module from main project in its module XML file, as you did above. You
would
then add that JAR to any launch or compilation scripts so that all
references would be resolved while running hosted mode or the GWT
compiler.
In the same way, you would refer to this JAR in your ant build.xml file
for
gwtc or hosted mode startup targets.
You could also refer to the GWT module's source folder and classpath
directly, as you did in your Eclipse configurations. This should also
work
in Ant by defining the appropriate path element. Something like the
snippet below should do the trick:
path id=apple.class.path
fileset dir=../Apple/src/com/gawkat/gwt/apple/client
include name=**/*.java/
/fileset
/path
target name=gwtc depends=javac description=GWT compile to
JavaScript
java failonerror=true fork=true
classname=com.google.gwt.dev.Compiler
classpath
pathelement location=src/
path refid=apple.class.path/
pathelement location=${gwt.home}/${gwt.dev.jar}/
/classpath
jvmarg value=-Xmx256M/
arg value=com.gawkat.gwt.Test/
/java
/target
This would be in addition to other path elements you would need to define
to
build your project.
Hope that helps,

Still don't see the problem.

if (w instanceof MyChildClass) {
MyChildClass child = (MyChildClass) w;
child.addClickHandler(this);

{
// whatever goes here - not sure what you mean - is the target

}
}
public void MyChildClass extends Composite implements HasClickHandlers
or
public void MyChildClass extends ClassWithClickHandlers
By the way, I'm pretty sure it's not allowed to add a single widget to
multiple parents widgets because it will completely break the DOM AFAIK.
Oh, and the above code has a memory leak since it never releases the handler
when the child widget is removed - that is left as an exercise for the
reader.

Re: libswt error on 1.6 RC2
That's the hosted mode trying to launch your browser. That particular
problem is caused by 1 of 2 issues (at least from my experience);
1. You are using a 64-bit JVM (which you aren't so this doesn't apply to
you)
2. You either moved, or don't have, the full GWT installation simply
added gwt-dev-linux.jar to your project.
When launching, GWT launches the hosted browser that is in the same
directory as gwt-dev-{platform}.jar. If you copied the jar into your
project without also copying in the browser (or the library is missing), you
will see this error.

Re: libswt error on 1.6 RC2
On a side note, I'd recommend just using OOPHM from trunk - I had far less
problems with it than with hosted mode on 64-bit linux, it's compatible with
the 1.6 project structure, and now that there's a wiki for it, it's very
easy to set up.

Re: Robust (cross-browser) check for a specific keycode?
Not always, this particular manifests itself for special keys like the
cursor keys etc. I believe quirksmode has a good table/chart which
tables keycodes. Perhaps a good future enhancement might be for GWT to
normalize the differences so developers can code without being aware
if these quirks. Unfortunately while most of the time the codes are
the same across all browsers there will of course in the spirit of
browser coding be exceptions to the rule often enough to make you
angry:).

Re: Folks.. I need a direction
You are missing something here. and that is RPC. Calling get set on your beans will modify that value only in the client browser. You want to communicate this value back to the server. So you need to make an RPC call. Now, you can generate a bean that will make RPC calls in its get set methods... why not? However, there is no such library or framework currently that work this way. With little code, you can create this behaviour. However I will recommend that let a bean be bean. do a rpc when set is called on the bean. Send the entire bean to your service layer. In service layer make the db call.

[gwt-contrib] Re: weak listener in GWT?
Hi Hiho, Thanks for your reaction. I don't want to sound (too) arrogant, but your solution is way to simple in my case (I wish I could use it). Because of the complex requirements I have to meet, I have several layers on top of basic widgets. That is: on the level I want to do some cleanup, these widgets are way out of scope (and I have too many widgets below). That is also desired behavior as on the level I want to do some cleanup, I don't want to directly see these widgets anymore as I am in another problem scope. I did some more prototyping and even my above suggestion doesn't solve my problem entirely as I sometimes want to remove part of the listeners that belong to a category. What I will do now: Like explained above: I have my own Form that contains Form field (these are the ones that wrap the basic widgets). These form fields (general gwt things) contain all kind of default behavior: validation, dirty checking, resetting, validation handling, etc.. (I have all kind of general form field for strings, birthday, datepicker, group of checkboxes, etc...) I will add a method to the Form field beforeRemove () that will always called by his managing Form just before removing (detaching) the form field of the Form, that gives the form field a change to do some cleanup. That is: when removing widgets/form field of the Form, I always do this trhough the manging Form. I will then add an extra method to the form field: addRemover (HasDestroy destroy), such that I can add things that need to be called by the Form field when beforeRemove() is called. In my builder I can then add instances to the Form field that need to do some cleanup. I think this is an elegant and nice solution, don't you think ? Da, I do miss the Weak Listener from SWT/Swing in cases like this... (It's back to the stoneage to do everyting yourself. Btw: don't get me wrong, I am not blaming GWT for this it's simple javascript that doesn't support this all) I would love to hear experiences of other developers have bounced their head against this issue. -- Ed --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---

-TODO(bobv): Copy wiki articles from incubator to here; cross-link the pages

-= Migrating from ImmutableResourceBundle =
+= Introduction =
+
+ The resources in a deployed GWT application can be roughly categorized
into resources to never cache `.nocache.js`, to cache forever
`.cache.html`, and everything else `myapp.css`. The ClientBundle interface
moves entries in the everything-else category into the cache-forever
category.
+
+= Goals =
+
+ * No more uncertainty if your application is getting the right contents
for program resources.
+ * Decrease non-determinism caused by intermediate proxy servers.
+ * Enable more aggressive caching headers for program resources.
+ * Eliminate mismatches between physical filenames and constants in Java
code by performing consistency checks during the compile.
+ * Use 'data:' URLs, JSON bundles, or other means of embedding resources
in compiled JS when browser- and size-appropriate to decrease the number of
round-trips entirely.
+ * Provide an extensible design for adding new resource types.
+ * Ensure there is no penalty for having multiple ClientBundle resource
functions refer to the same content.
+
+= Non-Goals =
+
+ * To provide a file-system abstraction
+
+= Examples =
+
+To use the ClientBundle, add an inherits tag to your `gwt.xml` file:
+{{{
+inherits name=com.google.gwt.resources.Resources /
+}}}
+
+Interfaces:
+{{{
+public interface MyResources extends ClientBundle {
+ public static final MyResources INSTANCE =
GWT.create(MyResources.class);
+
+ @Source(my.css)
+ public CssResource css();
+
+ @Source(config.xml)
+ public TextResource initialConfiguration();
+
+ @Source(manual.pdf)
+ public DataResource ownersManual();
+}
+}}}
+
+You can then say:
+{{{
+ Window.alert(MyResources.INSTANCE.css().getText());
+ new Frame(MyResources.INSTANCE.ownersManual().getURL());
+}}}
+
+= I18N =
+
+ClientBundle is compatible with GWT's I18N module.
+
+Suppose you defined a resource:
+{{{
+...@source(default.txt)
+public TextResource defaultText();
+}}}
+
+For each possible value of the `locale` deferred-binding property, the
ClientBundle generator will look for variations of the specified filename
in a manner similar to that of Java's `ResourceBundle`.
+
+Suppose the `locale` were set to `fr_FR`. The generator would look for
files in the following order:
+ # default_fr_FR.txt
+ # default_fr.txt
+ # default.txt
+

to provide localized versions of other resources, say `ownersManual_en.pdf`

+= Pluggable Resource Generation =
+
+Each subtype of `ResourcePrototype` must define a `...@resourcegenerator`
annotation whose value is a concrete Java class that extends
`ResourceGenerator`. The instance of the `ResourceGenerator` is
responsible for accumulation (or bundling) of incoming resource data as
well as a small degree of code generation to assemble the concrete
implementation of the ClientBundle class. Implementors of
`ResourceGenerator` subclasses can expect that only one `ResourceGenerator`
will be created for a given type of resource within an ClientBundle
interface.
+
+The methods on a `ResourceGenerator` are called in the following order
+ # `init` to provide the `ResourceGenerator` with a `ResourceContext`
+ # `prepare` is called for each `JMethod` the `ResourceGenerator` is
expected to handle
+ # `createFields` allows the `ResourceGenerator` to add code at the class
level
+ # `createAssignment` is called for each `JMethod`. The generated code
should be suitable for use as the right-hand side of an assignment
expression.
+ # `finish` is called after all assignments should have been written.
+
+`ResourceGenerators` are expected to make use of the
`ResourceGeneratorUtil` class.

are not always accessed by the program, thus inlining should be
configurable on a per-resource or per-ClientBundle basis.

[gwt-contrib] RFC : Adding deprecations to gwt.xml files
I'm in the process of migrating ClientBundle into trunk and it occurred to me that even if you remove the use of all deprecated types from your code, your module might still inherit an otherwise-unused module.

[gwt-contrib] Re: RFC : Adding deprecations to gwt.xml files
Sounds pretty useful. We should lock its behavior down more, though. Maybe just deprecated superceded-by=othermodule/ where superceded-by is optional. It would be helpful to have consistent-looking deprecation messages, so we probably shouldn't leave the text open-ended.

[gwt-contrib] Re: weak listener in GWT?
The solution that I suggest above, seem to work fine. BTW: I also had another look at the solution suggested by MiroSlav, but that is a technical soution that isn't correct in my case. His solution was to remove the global model listeners when the widget got detached. However, I can easily detach a widget/panel from one form and connect it to another form, which in my case is completely legal, but will result in correct behavior as the listeners are removed :(. So I solved it in a functional way by adding listeners to my Form Fields that are informed about form field removal/insertions. These listeners are added to the Form Field. I also have a Form listener that receives these kind of notifications, but couldn't be used in the form field builder as Form isn't know there, where as the Form field is. I hope it's of some use to others. -- Ed --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---

Maybe Locking it down is just going to get in the way because we can't cover all of the types of messages that you'd necessarily want to be able to convey in tag attributes. I may not be thinking about the spectrum clearly enough. Do you have some examples in mind? It seems like the 99% case is people saying Don't use this anymore; use that instead. Developers will just have to be judicious in their use of a free-form message; it more-or-less works for JavaDoc. (tangent: ModuleDoc?) In javadoc, it has always seemed like an un-usefully underconstrained tag. Everbody says exactly the same things, phrased every-so-slightly differently. If you want to lock it down, the most useful thing to be able to specify is a URL with additional information. I don't think that handles the most common use case, though. Wouldn't the most common thing be, Don't use this; use that? Most people will go to the absolute minimum trouble necessary, so it's unlikely people would be included to create an actual URL to point to.
