Eclipse GWT NoClassDefFoundError
I have a simple GWT project in Eclipse that requires another external project. Everything builds fine. But when I launch as a Google Web App using the App Engine I get a server-side NoClassDefFound for classes located in the external project. I've played around with the launch config and can't get around this. Under the classpath tab when I select the external project, Eclipse also chooses the project's dependent jars, but when I run the GWT project apparently Eclipse is not making these jars available to the App Engine. I can jar up the external project and cram it into WEB-INF/lib of my GWT project - the error goes away then. But this requires me to gather up every jar that the external project relies on and place it under WEB-INF/lib. I imagine Eclipse should be doing this for me through the launch configuration.

Making a fancy GWT Chart
My goal is to make a chart which shows standard deviations as a gradient on the vertical axis. I don't think it is easy to do this in the browser, so what I plan on doing is having the server render the chart to a BufferedImage and sending that to the client to display in an "Image" widget. The problem is that the Image widget only takes a URL, but how do I give it a bufferedimage? Also, is this the best solution for me to be using for making this gradient chart?

gin + Javascript Overlay types
Hi,
Is it expected that the following binding to a JSO type would fail?
bind(Jsot.class).in(Singleton.class)
The issue is: "Deferred binding failed for
'com.google.gwt.core.client.JavaScriptObject"
The get() method in the JSO type is
public final native Jsot get() /*-{
return this;
}-*/;
However, if I create the following binding:
bind(Jsot.class).toProvider(JsotProvider.class)
that has the following get() method
private Jsot jsot;
public Jsot get() {
return jsot;
}
everything is copacetic.
Thomas Broyer and I were talking earlier about using Provider methods
with JSO types. He mentioned the @Provides annotation, but I cannot get
that to work either.

Re: "semaphores" in gwt
I think your options are; a) Just nest one request inside the other. or b) Do both requests separately, but within both the OnResponse check a flag to see if the other one has finished as well.

Image/Absolute panel...how to make the clickhandlers fire on the abs, ignoreing the image?
Basically is it possible for an image widget to be "transparent" as regards to click events, passing them to the panel under it? I'm working on a panel-streaming engine; http://www.darkflame.co.uk/panalstreamer/panelstreamer.html Just click on the first option in the dropdown on the top right. (Anyone thats read Reinventing comics should recognize this idea ;) ) You will notice you can click and drag it around fairly easily when clicking on the "space", but if you click on the image panels the mouse will get 'stuck'. Any method to make the images on the absolute be completely ignored click-wise? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Country combobox and lookup country by IP

David, I will check out Winstone. It seems like a really cool program. It seems like it could work for me, since I wouldn't have to disrupt my existing setup. Discoveries like this make me really glad that I posted this question to the group :) elpix1, your comment made me aware of some of the issues I need to watch out for. I suspected that a framework might not really be necessary since Java provides most functionality inherently. With Python for instance, django makes communication with databases so easy that its hard to resist using a framework such as it. But I guess Java's JDO mechanism does similar things. Thanks a lot.

Re: Does GWT work in Snow Leopard?
I noticed that it should be possible for Google to release a quick patch of GWT 1.6.x that should allow users to run the legacy hosted mode under a Java 1.6 VM now. GWT's hosted mode, on the Mac, does an explicit check to ensure that Java 1.5 is being used. This check only existed because under Leopard, Java 1.5 is the only 32-bit JVM that was available. (I believe 1.6 was 64-bit only). I install Snow Leopard today, and it appears that while it only has Java 1.6, it appears to have both a 64-bit mode and a 32-bit mode. (Open "/Applications/Utilities/Java Preferences.app", and under the "General" tab you can see both of these modes.) So I think it should be possible to simply remove the explicit check that GWT does for Java 1.5.I have never built GWT from source, but I think I may try.

Re: Howto implement a RequestBuilder using gin

I'm doing the same exact thing, I'm still working to get it work with only one execute without actually having to add another parameter. So within an action class, I'll add the stuff that I need to send to the server here and then, when it reach de Dispatch call, if there's stuff to send, i'tll do a POST request with extra stuff, else, it'll do a GET request. It's the way it was originally designed, though without Gin and without command-pattern. > The pastie code demonstrates a unique class per object; which is > fundamentally the same as my first solution Actually, I make three extra classes client side for each action. Action/Reaction and the XML Unserializer for the type. Btw, it's less then what we have to do with gwt-dispatch, but once it's done, it's clear, concise and follow Better pratice guideline. Server side is a bit of a problem. Php doesn't have Generic and so, we have to select case wich class to build... Or I could do, one file per action and my client would call the appropriate file according to his action, so I don't have to select case it by exploring the xml file. Here's the problem for me. It takes a lot of work and it's suject to errors ! I'll have to find a nice and elegant proper way to do this.

Yes, I can see that. In another application, I used XML (Perl <--> JavaScript) for just that reason. It seems you are using Eclipse? I found that the XML & DTD editors were quite helpful constructing complex structures. The DTD was also input to an XML parsing/validating editor so that users could construct source documents in XML. These documents were sent to the client to be rendered as a questionnaire. The user responses were added to the questionnaire and the resulting document POSTed to the server for transformation via XSLTPROC into HTML. I can do the same thing to give the server some > informations by adding content to the request, read it on server side > and doing the action as said in my $_GET action string. Well, you're clearly doing exactly what I've been trying to do: take lessons learned from gwt-dispatch and formulate into something that works w/ RequestBuilder. I'm just not good enough at Java to understand how to get There from Here. Thank-you very much for taking the time to post this code. I will take the time to study it. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: WYSIWYG version of Google Plugin for Eclipse coming soon?
BTW, GWT Designer does support GWT-Ext and work on EXT GWT (GXT) is getting close to complete (SmartGWT will be after that). See... http://www.instantiations.com/forum/viewtopic.php?f=11&t=2204&start=30#p11874 The problem with many 3rd party widget packages (like the two you mention) is that they don't conform to normal GWT and/or JavaBean standards so they require a great deal of custom support within the GUI builder in order to provide a nice editing experience. The latest build also includes a multi-page CSS editor so that you can edit CSS files directly using the same CSS editing UI provided elsewhere in the tool.

Re: Howto implement a RequestBuilder using gin
First thing first, my implementation is for a server that don't have Servlet
! So gwt-dispatch wasn't the thing for me. I use it in another project, but
for this one, I had to build a dispatch api from scratch.
Si I decided to use XML for communication between PHP et my client and use
Request Builder to retreive that XML. So, I CAN'T use real object ! I have
to "serialize" them with a custom class before sending them and then, on
server side, deserialize them. There's a couple things to know when we use
that type of communication.
1. Server Side is unaware of client side classes. So we can't use clients
object or server object, that's why I have to "serialize" them in xml. I
could use JSON btw.
2. I don't really need a "response" classe like in the model, since this
classe is used to be send from the server to the client.
3. We have to do the work twice... That's shitty, but I had to make
Products obejcts in PHP as well as in java.
4. The only thing that is sent to the server by the client, is an URL !
The url to a specific php script that send back an XML reponse. So it's not
generic, because it's always String that your parse back in XML !
So now, here's the complete meat in action. Hope you'll find something to
use for yourself.
http://pastie.org/598942
So, in SearchProductPresenter I have the @inject is done here and I simply
call (dispatcher.execute) the appropriate action(GetProductsName) and when I
get the response(GotProductsName), I transform it from XML to the type I
want. In service side, when the PHP script is called, it looks at the $_GET
action and print out xml according to the argument.
It's work in progress, I have a couple things to do to generalize the
process on server side, and multiple type of objects actually doesn't work
verry well (For Batching purpose), I chose XML over json for this very
purpose. I can do the same thing to give the server some informations by
adding content to the request, read it on server side and doing the action
as said in my $_GET action string.

Christian

The pastie code demonstrates a unique class per object; which is fundamentally the same as my first solution. Also, there is no demonstrated linkage between the gin binding (ServiceCached) and the pastie code; which linkage would be interesting to see, but I'm guessing will also map one-to-one rather than one-to-many. I really don't see any way to get around the one-to-one mapping requirement given that RequestBuilder is implemented as a class, not an interface. As always, I'm willing to be proven wrong. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: The dreaded "No source code is avail" error - ARGH!!!!
SOLVED!!! Isn't always something real dumb. So my final piece of misunderstanding on element was keeping this from compiling. The inherited module xml file was under gwt/. The path component of the element is relative to the directory in which the xml module file resides. So it looked like this ... gwt/ Patient.java Patient.gwt.xml So my entry was likely making the compiler look for source under gwt.gwt.Patient. LOL I changed it to which I doubted was legal. But it worked!!! Hope this might help someone.

Re: The dreaded "No source code is avail" error - ARGH!!!!
Ok, so now I have some idea of how the element works. I've gone a little further and I have created a jar file with gwt.Patient (both source and class files). gwt.Patient.gwt.xml now includes a . I think I need this since I am using a non-standard package convention that does not include client/server packages and I need to tell the GWT compiler where the code for this inherited module exists. This jar file is not in my projects classpath but I am getting the same old tiresome error. Any help would be greatly appreciated.

Re: WYSIWYG version of Google Plugin for Eclipse coming soon?
Hi Keith, I own the Designer, the only warning I would give about purchase is this; only get it if you are not planning on using any 3rd party widget libraries that are up to date. SmartGWT and GXT cannot be designed yet. They are working on it but you should not hold a project up for that. Other than that limitation (I am using GXT), when designing and laying out individual widgets (Composites mostly), it is great and fast. The CSS editor is really nice that integrates with it. The more recent version is much more flexible and solid. I usually create a sandbox widget that I use for my designs right now then copy/paste the layout code into my real widget. If you are using pure GWT this is not an issue, as long as your widgets are not terribly complicated especially at construction time.

Re: Java server frameworks for GWT
I didn't have any experience with Java servers also, having worked mostly with Python, but using servlets with the GWT RPC model is very easy. I run my test GWT application with Tomcat and Jetty with no problems. I think any of these servers are OK for testing and even production. I am not currently using any framework, but I am researching an ORM to use with my project (currently I am using standard JDBC). An ORM can really boost productivity but there is some issues using ORMs with GWT, since you can't transfer through RPC entity classes generated by the ORMs. These classes need to be converted to/from DTOs before RPC or you need to user some class converter (gilead, dozer).

TreeItem padding does not work
Hi all,
I'm trying to change the padding in the TreeItems I have in a tree. By
default, the TreeItem html code generated looks like this:
SOME HTML CODE OF A WIDGET
As you can see there is a 23px left padding for the indentation of the
elements, that is the one I want to modify. I have used different
approaches, firstly, I tried to create a style and add it,with the
code:
treeItem.addStyleName("divwithoutpadding");
. divwithoutpadding{
padding-bottom: 3px;
padding-left: 3px;
padding-right: 3px;
padding-top: 3px;
}
and the resulting code is:
cadena10
but this does not work, then I tried :
treeItem.getElement().getStyle().setProperty("padding", "3");
and
treeItem.getElement().getStyle().setProperty("paddingLeft", "3");
but though I can see the html code of the treeItem component in debug
mode with the padding set as I want, when I see again in the browser,
I get the same 23px left padding, I have been following the tree until
I add it to the RootPanel, and the padding continue always with the
one I set, so, seems that in the process of the final code generation
the value is changed, am I missing something or there is a bug?
thanks in advance

Re: Hosted mode hanging 4 out of 10times
Hi all, Even if this thread isn't so helpfull, I can said that I've the same problem as rahul. In hosted dev mode sometime I get "Connecting to site 127.0.0.1", specialy on low end dev machine. The same project, on the same OS and exactly the same dev environment, works on Core2duo but failed sometime on Atom 330. I know Atom 330 is somewhat slow and not really adapted to code with windows+eclipse+GWT+jetty but very usefull to test applications on low end final env. I think some parts on GWT hosted mode doesn't wait enough for others parts to be ready. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

The dreaded "No source code is avail" error - ARGH!!!!
I understand what this issue is and basically how to solve it. Namely, I need to create a module xml file for code that I want to use in my client and inherit it in my client's xml module. In my case, I have a widget that calls a service through GWT-RPC. The service returns a simple DTO (that I define it in an external project and bundle into a jar file and include it in my client's Eclipse project)... I call it "gwt.Patient". -Eclipse is good with what I've done [check] -I use in client module xml. [check] -I create gwt.Patient.gwt.xml (I know without this GWT compile will immediately complains it can't find it) [check] >From what I have read, this is all I need. Alas, it is not true. Still I get "did you forget to inherit a module" when I do a GWT compile for every class that references gwt.Patient (the service interface, the async interface and the widget class). I couple of things I have done to work around this ... -turned on Debug level when compiling: I see GWT inheriting the module. But I also see some indication of gwt.Patient being "excluded" in some context - what context this is isn't clear from the logging. -the above made me think I needed to do something with tags in the client's xml. I kinda understand this tag in that it includes and excludes source from GWT compile. But I have yet to read a good explanation of what 'path' means. At any rate when I do I do get around the error but then it complains ... "Checking rule [ERROR] Unable to find type ..." ARGH Anyone understand what's going on here and what I am doing wrong?

Re: Howto implement a RequestBuilder using gin
Hi Christian:
Thanks for the meat!
I hope you have time for a few questions...
So ServiceCached is:
Public interface ServiceCached {
public class GetProductsName implements Action;
public abstract class GotProductsName implements RequestCallback;
}
Action: from gwt-dispatch? How do you get past the "extends
serializable" part of its definition? Serializable seems to bring in
all kinds of Java RPC baggage; which definitions cause problems at
link time. I notice that here it's not bound to a generic type.
Why is GotProductsName an abstract class?
I'm assuming that the injection is something like:
@Inject
Fred (ServiceCached serviceCached) {
this.serviceCached = serviceCached;
}
So how does that get us to GetProductsName?
Looking forward to your responses!

I use Winstone on my server --- it's very small and lightweight but runs GWT servlets perfectly. As my server box is actually an ARM based device with interpreted Java only (no JIT!) this is kinda necessary. Like most servlet engines it can work either as a standalone webserver or as an extension for an existing server. I use it in conjunction with thttpd, so that thttpd serves all the static files and Winstone is invoked for the RPC entrypoints only. - -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ─ http://www.cowlark.com ─ │ │ "People who think they know everything really annoy those of us who │ know we don't." --- Bjarne Stroustrup -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iD8DBQFKmTbnf9E0noFvlzgRApPSAKCQJrRtuMkesS21NU952QuENyvbGACgiXW7 AOo4B8bj/U+Nv2lKR3wHpig= =LFhQ -END PGP SIGNATURE- --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Howto implement a RequestBuilder using gin
Huh, I have done this with a command pattern style... bind(ServiceCached.*class*).in(Singleton.*class*); As simple as that ! I use XML between client and server. Action class know what is the url to use and when a response is received, I have a class that transform my XML in object. Works fine, I have to rework the cache a little because for now I use a static array.

Re: Howto implement a RequestBuilder using gin
It looks like that's the only way. One wrinkle that was not mentioned in the original post is that the URL argument to a RequestBuilder instantiation is RESTful with volatile path components. IOW, instance bindings will not solve this problem. I'm using binding annotations: bind(RequestBuilder.class).annotatedWith(XXX.class).toProvider(XXXRequesterAsync.class); bind(RequestBuilder.class).annotatedWith(YYY.class).toProvider(YYYRequesterAsync.class); I'm using the provider binding because I want only one instance of each implementing class. The XXXRequesterClass knows what CGI method and URL to use when instantiating a RequestBuilder object. The volatile URL path components are concatenated at runtime. Each annotation class (XXX.class, YYY.class) is an interface. Discuss amongst yourselves.
