Re: Why does GWT's API differ so much from the Javascript one?
Yes but it isn't clear how to share code between the client and server -- especially in the case the original poster mentioned: org.w3c.dom.* We were forced to wrap all the org.w3c.dom interfaces in classes that implement the com.google.gwt.client.xml interfaces. I understand that GWT can't implement some parts of org.w3c.dom.* (e.g. namespaces) but rather than introduce a new interface I would rather have had errors in those cases. The truly best situation would be if the org.w3c.dom interfaces were defined as extending the com.google.gwt.client.xml interfaces. But I don't see how that could be done.

Re: Why does GWT's API differ so much from the Javascript one?
org.w3c.dom is such a pain to work with, you'd better define your own API that you implement on top of it (or JDOM or dom4j or whatever) on the server-side, and com.google.gwt.xml or com.google.gwt.dom on the client-side. This is exactly what the Wave guys did, and it works pretty well: https://svn.apache.org/repos/asf/incubator/wave/trunk/src/org/waveprotocol/wave/model/document/MutableDocument.java (their implementation is a bit convoluted, as it's layered with IndexedDocument that is necessary for the Operational Transformation operations, but my point is that it's possible and quite easy); it allows for such things like easy iteration: https://svn.apache.org/repos/asf/incubator/wave/trunk/src/org/waveprotocol/wave/model/document/util/DocHelper.java and https://svn.apache.org/repos/asf/incubator/wave/trunk/src/org/waveprotocol/wave/model/document/util/DocIterate.java -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Window.open returns void. Stuff is missing like document fragments. It seems to me like none of this stuff has to be rewritten if it all the interfaces were generated from webidl then the implementations from GWT generators. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Display first web page in GWT
I am a complete beginner with GWT and web development generally and I
trying to build a GWT app using baby steps so I can understand each
step. I have created a tiny app that simply as a styled layout panel
in the RootPanel. My code in onModuleLoad is:
public void onModuleLoad() {
LayoutPanel p = new LayoutPanel();
p.setStylePrimaryName(appbackground);
RootLayoutPanel.get().add(p);
p.setVisible(true);
}
and I have the following entry in the application style sheet:
appbackground {
background-image: url (WEB-INF/images/background.jpg);
width: 80%; height: 80%; border: 10px,solid,red;
}
My problem is that I do not see any evidence of the styling in the
displayed web page. I have verified that the onModuleLoad() method is
being called. Can anyone spot what I could be doing wrong:

Re: GWT HTTP RequestBuilder
Hi Jens Yes i am sure, i got response code as 200 and the jsp from J2EE server is also getting displayed, sorry for typo my application is in server 2 and J2EE application is in server 1. to overcome SOP only, we have setup the 2 servers in above format. so that domain name and port are same, both servers end with 1. example.com 2. and also both servers have same port no. 8111 when i went through the sop policy in gwt documentation, i came across below way of loading images and javascript files from different server. which i felt is similiar to our setup. part of documentation is pasted below: However, many organizations setup their deployment platform in such a way that their main host HTML page is served up from http://mydomain.com/, but any other resources such as images and JavaScript files are served up from a separate static server under http://static.mydomain.com/. In older versions of GWT, this configuration would not be possible as the SOP prevented the GWT bootstrap process from allowing script from files that were added from a different server to access the iframe in the main host HTML page. As of GWT 1.5, the bootstrap model now provides support for this kind of server configuration via the cross- site linker (xs-linker). When using the cross-site linker the compiler will still generate a module.nocache.js that you will want to reference within your index.html. The difference though, is that the module.nocache.js produced by the cross-site linker will link in a cache.js file for each of your permutations rather than a cache.html file. To enable the cross-site linking simply add the following to your module.gwt.xml and include a reference to your module.nocache.js in your index.html as you normally would. add-linker name=xs/ according to this doesn't our setup overcome SOP.

Also shouldn't your code snippet use factory-dev109.example.com if server 2 is the server you want to request? Well but in general you have three options to make cross domain requests: 1.) You have to use a reverse proxy so you can make requests to external servers without leaving the domain which serves the GWT application. 2.) Make a GWT request to server 1 (works because there is no SOP) and then let your server side code on server 1 do a request to server 2 using plain java. 3.) Use JsonpRequestBuilder. But this would require some rewrite of your server 2 code as you now need to provide your data as JSON and also wrap this JSON data in a javascript callback function whose name is send by GWT to your server 2 via a GET parameter. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Deferred binding with ClientBundle?
How can I override a ClientBundle through Deferred binding to override or add resources like images? Explain: I have a CLientbundle LoginResources that extends from Clientbundle. The LoginResources contains images that are used in the CSS file. I like to be able to use the RichLoginResources interfaces that extends LoginResources that override some images methods in LoginResources such that other images are shown (I want to use this for Themes). So my gwt configuration contains: --- replace-with class=theme.standard.RichLoginResources when-type-is class=bla.LoginResources / /replace-with -- The ClientBundle is created through: GWT.log(LoginResources.class); This works well until I add the above gwt config. GWT complaints that RichLoginResources is abstract: -- 00:05:16,827 [ERROR] Deferred binding result type 'theme.standard.RichLoginResouces' should not be abstract --- I understand the error as RichLoginResources is an interface, just like LoginResources. However, I would expect that GWT is smart enough to see that it concerns a ClientBundle an generate the code itself, just like it does for LoginResources without the above gwt config. What is going wrong here? And how could I make this work? - Ed -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Breakpoints don't work in Development Mode
Hi, after switching to a Mac I just set up Eclipse and GWT and was trying to debug the Stockwatcher sample application. But the debugger doesn't stop at any breakpoint, no matter if it is located in client or in server code. (Yes, I'm sure that I started 'Development Mode'.) In non- GWT projects debugging works just fine. Here some informations about my setup: OSX 10.7, JDK 1.6.0_29-b11-402, GWT 2.4.0, Eclipse Indigo Service Release 1.

EntityProxy equals
Hi all, I was trying to check the presence of an EntityProxy in a SetEntityProxy [i.e. set.contains(proxy)]. This returned false even though the proxy was an element of the set. As it turns out EntityProxy.equals() doesn't work, or, more precisly, it seems to behave as the default equals() and check reference equality instead of value equality. So how do I get a working value checking equals? Without it, SetEntityProxy is just about useless. I didn't see anything relevant in [1] and Google was no help either. (I did find a similar question but it went unanswered.)
