  • GWT and a jaxb objects

    - by arinte
    I am trying to use GWT to build objects on the client side that would be sent to a web service elsewhere. These objects are generate through JAX-WS which I am pretty sure uses jaxb to build objects from the xsds that are in the wsdl. Anyhow, GWT was supposed to be able to support this by ignoring annotations or whatever, but it isn't working for me. Here is one of the errors that I am getting: Line 4: The import javax.xml.bind cannot be resolve I am using GWT 2 and the Google plugin for Eclipse.

  • gwt typeahead missing

    - by arinte
    I have a GWT app with a bunch of textboxes. In firefox I would expect that when I type a word in a textbox that I have already typed in and submitted, that firefox would offer to autocomplete that text. But for this GWT app it is not happening. Also in IE it seems that none of my css stuff is loaded. And when I IE developer tools on my GWT page, it can focus in on any of the textboxes it just focuses on the encompassing DIV around all the textboxes.

  • Java + GWT + GSON on server side

    - by Jan
    Hi everybody. I already read that there is no possibility to run GSON in GWT client code, but that it is possible to run it in server code. The latter one is which I'm trying to achive, but not getting to work. I thought any class within the com.whatever.server package has access to the whole JRE namespace including reflection. It seems that that is not the point. So how managed all those developers to use GSON in GWT server code? (I'm new to GWT, so the answer may be really easy.) Thanks.

  • GWT tries to load a deleted module

    - by Dmitry
    I am using Eclispe with Google plugin for AppEngine and GWT. Recently I created a test GWT module, but eventually it has been deleted from the project and I can not find any sign of it in the project now. However, whenever I run the web app locally, I get in console the following message: Loading modules com.piq.exemity.Test [ERROR] Unable to find 'com/XXXXXX/Test.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source? Has anyone got any idea where it can be hiding?

  • GWT on Python App Engine

    - by Koran
    Hi, I have a python app engine code (matured backend) - and we are now planning to have a front end for that code. I was wondering whether it is possible to implement GWT as the front end. Even though Alex Martelli in this post [1] mentions it is not possible, a comment to that post suggests that it is indeed possible using rpc over json for GWT. I was unable to understand how this is possible. In app.yaml file, we have to specify the language to be python, right? In that case, how can it compile GWT based on JAVA? Are there any examples on anyone doing that? Can someone help me out? It would be extremely helpful.

  • Looking for substantial open source GWT/App-Engine project to use as reference

    - by tempy
    I'm working on GAE-J/GWT app, wherein a desktop app connects to the GAE-J component, and there is also a web-app component whose front-end is written in GWT, and the GAE-J backend supports both the desktop app and the web app. I have a good amount of experience with writing pure server code and desktop code, but not so much on the web-app side of things. So I'm looking to study some good sophisticated open source code to see how other's have done things, but I can't find much open source GWT and/or GAE-J stuff, other than frameworks. Does anyone know of any good projects out there?

  • recommend a server side technology for gwt (beginner)

    - by user486503
    hi all ! I am developing a gwt project and am looking for an appropriate server side technology. it should support be open source and support user login (and not using openID...) with password recovery etc it seems that the de-facto standard would be spring + hibernate. however, I am unfamiliar with neither of them and understand that the learning curve (especially for spring) is very high. gwt was quite easy to learn using GOOG's excellent online tutorials but the spring equivalent seem to impose lots of configuration files and deeper understanding of its internals. so I am looking for a simpler server side technology to deploy my gwt app. I am definitely prepared to learn a new framework if necessary but not something that would take me 2 months just to understand the fundamentals... any ideas...?

  • How to set CSS style colors in GWT

    - by AmaltasCoder
    I have a GWT + AppEngine application that lets users create online polls. I want to let the poll creator choose from a variety of themes for his poll. We will save the theme a poll creator chose on the server and whenever a poll respondent access the poll he will get the questions with the chosen theme. A theme for us means a set of 4-5 colors which we will use to style the poll page. Our client side application is a GWT application with styles set inline in UiBinder templates elements, for example: <ui:style> .header { background: color1; padding: 6px 6px; } .anothercssclass { background: color2; padding: 6px 6px; } </ui:style> Please suggest how we can set the color1 and color2 from the theme saved on server. Please note this is NOT a GWT module theme question.

  • Trouble with setting entry point for GWT service

    - by Xorty
    Hello. I've followed serveral tutorials and read official docs at code.google.com, but still didn't manage to resolve this thing. I am creating simple service that'll check if user can be logged. CLIENT SIDE: public interface LoginService extends RemoteService { /** * Checks, if user has valid login. * @param user User's login. * @return True if such a login is in the database. */ boolean isValidUser(User user); } And here is Async interface: public interface LoginServiceAsync { /** * Checks, if user has valid login. * @param user User's login. * @param callback the callback to return True if such a login is in the database. */ void isValidUser(User user, AsyncCallback<Boolean> callback); } SERVER SIDE: public class LoginServiceImpl extends RemoteServiceServlet implements LoginService { /** * serial version UID */ private static final long serialVersionUID = 1044980345057997696L; /**{@inheritDoc} */ @Override public boolean isValidUser(User user) { boolean success = true; //TODO change } } Now I have entry point class MailClient.java. I append here widget like: CustomWidgets.getLoginWidget(this); // access rootPanel and append widget Now I need to make actual call to my service, and here is problem: LoginServiceAsync loginService = (LoginServiceAsync) GWT.create(LoginService.class); User user = new User(boxName.getText(), boxPassword.getText()); AsyncCallback<Boolean> callback = new AsyncCallback<Boolean>() { @Override public void onFailure(Throwable caught) { Window.alert(caught.getMessage()); //TODO change } @Override public void onSuccess(Boolean result) { Window.alert("success"); //TODO change } }; ((ServiceDefTarget) loginService).setServiceEntryPoint(GWT.getModuleBaseURL()+"login"); // dunno what should be here So to recap, I don't know how to set service's entry point. Here's my MailClient.gwt.xml file: <module> <inherits name="com.google.gwt.user.User"/> <inherits name="com.google.gwt.user.theme.standard.Standard"/> <entry-point class="com.xorty.mailclient.client.MailClient"/> <servlet path="/login" class="com.xorty.mailclient.server.servlets.LoginServiceImpl" /> <inherits name="com.xorty.mailclient.MailClient"/> <inherits name="com.xorty.mailclient.MailClient"/> <inherits name="com.xorty.mailclient.MailClient"/> <inherits name="com.xorty.mailclient.MailClient"/> <inherits name="com.xorty.mailclient.MailClient"/> </module> My web.xml file: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <!-- Default page to serve --> <welcome-file-list> <welcome-file>MailClient.html</welcome-file> </welcome-file-list> <servlet> <servlet-name>LoginService</servlet-name> <servlet-class>com.xorty.mailclient.server.servlets.LoginServiceImpl</servlet-class> </servlet> <servlet-mapping> <servlet-name>LoginService</servlet-name> <url-pattern>/com.xorty.mailclient.MailClient/login</url-pattern> </servlet-mapping> </web-app> And here is screenshot of project structure:

GWT module 'com.vaadin.terminal.gwt.DefaultWidgetSet' may need to be recompiled I've tried cleaning the project to no avail.

  • Comparing GWT and Turbo Gears

    - by sechastain
    Anyone know of any tutorials implemented across multiple web application frameworks? For example, I'm starting to implement GWT's Stock Watcher tutorial in Turbo Gears 2 to see how difficult it will be to do in Turbo Gears 2. Likewise, I'll be looking for a Turbo Gears 2 tutorial to implement in GWT. But I hate to re-create the wheel - so I was wondering if anyone was familiar with such projects and/or would be interested in helping me work on such a project. Thanks, --Spencer

  • GWT styles not applying

    - by sernaferna
    I'm creating a GWT application that uses UiBinder, and I've come across a bizarre problem where styles aren't applying to my elements--until I refresh the browser, and then the styles briefly get applied, in that fraction of a second before the page refreshes. In other words: Open page; none of my defined styles are used. Hit Refresh For a fraction of a second the styles are used, before the page goes blank The page reloads, without the styles again I'm going to include my entire *ui.xml file, because it's not too big. <!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"> <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui"> <ui:style> .idLabelStyle { font-weight: bold; text-align: center; width: 100px; border-style: solid; border-width: 1px; margin-right: 5px; } .nameLabelStyle { font-weight: bold; text-align: center; width: 500px; border-style: solid; border-width: 1px; margin-right: 5px; } .addressLabelStyle { font-weight: bold; text-align: center; width: 500px; border-style: solid; border-width: 1px; } </ui:style> <g:HTMLPanel> <g:HorizontalPanel> <g:Label addStyleNames="{style.idLabelStyle}">ID</g:Label> <g:Label addStyleNames="{style.nameLabelStyle}">Name</g:Label> <g:Label addStyleNames="{style.addressLabelStyle}">Address</g:Label> </g:HorizontalPanel> </g:HTMLPanel> </ui:UiBinder> I really hope I'm missing something simple.

  • GWT ScrollTable performance problem

    - by wolfi
    Hey all, I'm having a little performance problem with the gwt (incubator) ScrollTable. It's rendering really slow. Not even when I'm loading a lot of data - it happens already with a few rows. Or is it possible that the deserializing of the data takes so long? I'm using GWT 2.0 and IE. Maybe someone has the same problem or a solution for it. Thx and Happy Easter!

  • GWT and MVC type calls

    - by arinte
    I have a GWT app that when launched it takes you to a page with just a menu. So as a shortcut type thing I would like the users to be able to go straight to the page they want. So if the default start page is x, the should be able to say x/add and it will take them to the add page. How would I get that in gwt? Do I need a bunch of different entry points?
