GWT: Retrieve generated classname
This is the whole point (well, one of them) of CssResource: that the same class name in sources is turned into different ones once compiled, so you never fear name conflicts. Generated names depend on the fully-qualified name of the CssResource interface, so you have to use the exact same...
How to create an API REST?
As far as I understand, you want to implement a RESTful service (Web API). GWT targets the Web UI to be able to build it using Java and compile it into JavaScript. I think that it's not what you expect. Here is a link that provides you hints about concepts...
SoycDashboard$FormatException on GWT Compilation
SOLUTION After testing and debugging GWT Compilation process it appears to be a SAXParser problem. I´ve specified the default SAXParser for gwt compilation jvm using -Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl and the issue was solved....
How enable production mode in GWT 2.7 application
gwt,gwt-super-dev-mode,gwt-maven-plugin
Ok thank you very much for your comment. Indeed, my problem concerned the *.nocache.js and *.devmode.js files. I started my project (my first one in GWT) in 2.6 version and these files were created (by dev and super-dev-mode) and versionned by my fault. So, when my jenkins deployed my project,...
Is it possible to get non-random names for Cache Files from GWT Compile
If you only have one generated permutation, and you want to ignore the cacheing and give the file your own name, you can use the single script linker - this will generate only one JS file with both the selection script and the compiled app. This only works with one...
The import javax.ws cannot be resolved with GWT on Eclispe
With GWT you cannot use all Java libraries available for server side Java. You are restricted to a small JRE emulation subset. As a consequence you cannot use any librariy using standard Java classes outside of the emulation subset. Often there are special GWT libraries for the same purpose. You...
What Cell,Table can I use to create a grid of only images in every cell, in GWT?
css,gwt,web-applications,grid,cell
You can use a simple FlowPanel as a container, and add each image with a float set to "left". Alternatively, you can use a flex-box model with flex-flow: row wrap on a container. You don't need any widgets for this. This is simple CSS, and it will give you the...
Getting Exception in thread “main” java.lang.VerifyError: class com.google.gwt.dev.HostedModeBase$ArgHandlerNoServerFlag
gwt-dev-windows.jar is an old dependency from pre-2.0 GWT (you should have already removed it when updating to 2.0 a while ago), and it conflicts here with the newer gwt-dev-2.7.0.jar. BTW, unless you want to continue using "classic DevMode", you'll also need gwt-codeserver-2.7.0.jar. Last, but not least, you'll likely have to...

List servlets in a java webapp (running in tomcat)
I would write a simple JSP or ServletContextListener to read all the ServletRegistratioins from the servlet context and display them. So your JSP/ServletContextListener would read the data from servletContext.getServletRegistrations(); and just display it. Edit @WebServlet(urlPatterns = "/mappings") public class TestServlet extends HttpServlet { private static final long serialVersionUID = -7256602549310759826L;...
Is it possible to use widgets in a GWT ToggleButton?
ToggleButton's g:downFace takes an ImageResource as an image= attribute: – Source: http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/CustomButton.html But you cannot use both an image and text that way. AFAICT, you can however use an image and text through HTML (but without widget): <g:downFace>downFace Text <img src="{res.wantedImage.getSafeUri}" /></g:downFace> or through a @sprite in a CssResource: <g:downFace>downFace...
How to get gwt jars version information if it is not available in manifest file?
GWT provides the information in several ways: gwt-dev.jar contains a com/google/gwt/dev/About.properties you can launch the gwt-dev.jar (java -jar gwt-dev.jar, or java -cp gwt-dev.jar com.google.gwt.dev.Compiler, and it'll give you the version information) the version is also available into the generated JS, and/or accessible from client code using GWT.getVersion() ...

Set focus to an Input in a gwtbootstrap3 Modal
gwt,twitter-bootstrap-3,gwtbootstrap3
You should be listening on the ModalShownEvent (note: Shown, not Show). ModalShowEvent is fired when the modal is requested (for example, programmatically) to be shown. ModalShownEvent is fired when the modal is actually shown. This somewhat confusing naming is based on the events of the native Bootstrap Modal's events: show.bs.modal...
MGWT AnimatingActivityManager
In general with any GWT 2.6 to 2.7 conversion, make sure you do not have any straggling references to GWT 2.6. There was one 2.6 JAR file in my 2.7 implementation.
GWT - [ERROR] Line 265: Failed to resolve 'org.AwardTracker.client.RichTextToolbar.Strings' via deferred binding
Strings != String. Your example new String() is a creation of a new String value. Strings is something different. In short it will bind text from property file with the Strings interface due to the fact it extends Constants. See the GWT documentation about how this works for a more...

Changing tree node font color
A ValueProvider isn't meant for styling - it passes the value to be shown (or processed). So if you pass an HTML element, by default it will be printed out as you described. One possible solution is to set a custom cell. Change your Tree to Tree<SubmissionMenuData, SubmissionMenuData> and return...
How to group fields to get one change value handler
I think you can achieve more or less the same behavior by registering the same handler on both filterItemName and filterItemAmount : ChangeHandler handler = new ChangeHandler() {...} this.display.getFilterItemAmount().addChangeHandler(handler); this.display.getFilterItemName().addChangeHandler(handler); ...

IE 11 isn't officially supported in GWT 2.5.1 (I couldn't even tell which permutation is selected in this case; and it depends on X-UA-Compatible). Try updating to GWT 2.7.0, where IE11 has been tested, and should select the gecko1_8 permutation....
“Development mode is loading…” and “Waiting for launch URLs” in GWT
java,gwt,google-plugin-eclipse
Both errors (missing gwt-codeserver, and unknown argument) hint that the Google Plugin for Eclipse didn't properly detect the version of the GWT SDK you're using. GWT 2.3 is now really old, so I'd suggest trying with GWT 2.7. As you're beginning with GWT, it's also better to start right with...
How to transform elements to widgets?
try with something like FlowPanel panel = new FlowPanel(); HTML wrap = new HTML().wrap(myElement); panel.add(wrap); RootPanel.get().add(panel); note : the FlowPanel is not strictly necessary. It adds a <div> around your elements (and HTML.wrap() will add one too). A panel could be helpful if you want to group elements/widgets together....
java.lang.NoSuchMethodError: com.google.gwt.util.tools.Utility.versionCompare - Google Web Toolkit SDK 2.6.0
If this is a Maven project, then M2Eclipse and the Google Plugin for Eclipse should auto-configure the project to use the GWT referenced from your POM, and not the one you could have installed in your Eclipse. So the problem is that you have GWT 2.6 on the classpath; your...

Filtering for UI developed using GWT
We have a GWT app that supports sorting and paging of large tables. Both is done in the backend. First, I'd say it depends on how fast your backend can handle these requests. If it's about 20ms or less per roundtrip you could do it in the backend. Another point...
GWT: How do I initialize the back-end before the server starts listening? [duplicate]
You could try with a ServletContextListener. Check this : http://www.mkyong.com/servlet/what-is-listener-servletcontextlistener-example/ . In short, you define a context listener that gets triggered when the webapp starts up, and there you can initialize your server-side logic. Here's an example : public class MyServletContextListener implements ServletContextListener{ @Override public void contextInitialized(ServletContextEvent ctxEvt) { System.out.println("this...

Using tag-specific CSS selectors in GWT CssResources
Okay, now that I've tested a little, as Igor Klimer requested, I found out that the tag-specific selectors work the way they should and that pseudo-selectors can also be used. I hope that will be useful for someone googling this question in the future. Edit: Even CSS3 Animations work perfectly...
cannot debug GWT native code within gwtmockito
After digging in the GwtMockito code, it seems there are a certain set of classes that are stubbed and some methods' body is removed. Therefore it's not possible to debug those methods. The question that remains is that somehow GWTMockito breaks the code coverage tool(EclEmma) which shows less code covered...

GWT FlowPanel not adding widget
You tell DataGrid to take all available space inside the FlowPanel. Then you tell Grid widget to do the same. The result is that your Grid has a height of zero, since there was no space left for it after the DataGrid took 100% of the FlowPanel height. You either...

Grid with rows in anchor not visible in GWT (UIBinder)
You create your ticketTable and your links with UiBinder (createAndBindUi) and then you create a new Grid (re-assigning the ticketTable field BTW) and move your links to it (setWidget), but you never actually use that Grid anywhere.

HibernateException: Could not instantiate dialect class when using HTTPS for GWT

GWT 2.7 Super Dev Mode not working while testing on the same network
As Thomas pointed out, the problem I had was that from GWT 2.6 onwards, if you want to test from other devices in the same network, you have to whitelist the addresses you'll be using in each *.gwt.xml file using a command line like this: <set-configuration-property name="devModeUrlWhitelistRegexp" value="http://(localhost|127\.0\.0\.1|192\.168\.150\.(\d{1,3}))(:\d+)?/?.*" /> I...

How should I set a custom style on a object that is a gwt component?

There are two ways to do that. First, you can define the rule in CSS. You do need to learn HTML and CSS for web development - no way around that. Second, you can set a particular CSS property directly in your code: loader.getElement().getStyle().setFontSize(24, Unit.PX); ...
Servlet not found from a GWT web application
One likely difference is the webapp's context path. In dev, the web app is deployed at root (contextPath=/) whereas in Tomcat it's using the name of your war file by default (contextPath=/mywebapp/).

GXT MessageBox with scrollable content

GwtMockito - click handlers for many buttons
Let's read that code together: whenever getClearButton() or getChangeStatusButton() is called, return this.button; that is, the very same button for both method calls, which means you won't be able to tell which is which: it's just the same. whenever addClickHandler is called on that mock button, store the click handler...
How to configure mvn/Jrebel/wtp/gwt/eclipse to work smoothly with changes on the service interface
The client side doesn't need anything special. The server side though requires the RequestFactory and all its RequestContext and proxies hierarchy to be processed by the validation tool.

How to append a link to gwtbootstrap 3 InputField
The HasText bit is about InputGroupAddon, not Anchor. "Text-only context" (implied by implementing HasText) means you can only put, well, text into that widget.

I'll assume that you've got the code generation side covered, and only focus on how we might pick the correct implementation in GWT: but you'd still have to somehow feed the factory with the current context, e.g. the current locale). We could do this at runtime, as you suggest, but...

Problem solved....

The details depend on your build tool and/or IDE, but the goal is to have all server-side classes in the webapp's WEB-INF (either in WEB-INF/classes, which is probably the case for your GWT project, or in a JAR in WEB-INF/lib). This will be necessary anyway when deploying the webapp to...
Is it possible to shadow Vaadin Applicaitons
well, although it could be possible to have this feature in Vaadin, it is not implemented right now, nor planed. Vaadin RPC mechanism maintains synchronised set of states between the user session in server side and javascript in client side. In theory it could be possible to code some kind...
