Hi everybody! I have to send an email from a gwt project using java mail api. I manage to do it with a normal java application (a Main project, a Junit test, whatever) but it just doesn't work inside an RPC call on GWT (version 1.7.1). I think I'm using the proper java libraries as I can send this email outside GWT. I'm using it in host...
Hello Is there a plugin for Eclipse GWT or any other method to automatically deploy and run GWT app on Tomcat (or any other Serlvet container)? For the moment the only method I know is copying the compiled classes into WEB-INF directory but this is an arduous work. Additionally you have to configure Apache Tomcat manually. I'd like to h...
I have an RPC service in GWT that needs to return a List. The List can be filled with various types of objects, all of which are serializable and all of are referenced elsewhere in my service so they should be available to GWT RPC. However, unless I put on a generic type parameter (e.g. ArrayList<String>), GWT gives me the warning: R...
Hi, I'm currently writing a web application in java using GWT 2.0 in eclipse. I wanted to know if there is a way to use Gson library in a GWT application's client code. and if there is a way - please tell me how... Thanks! ...
I've been a C++ programmer for 15 years... I've done NO Java development... I HAVE built websites with HTML, CSS, Javascript and PHP... Now, my question is this: Is the productivity gain I'll get from using something like GWT really worth the learning curve for me? I don't really have a strong desire to learn Java... I've never used Ecl...

In my main class i have a private class which extends PopupPanel and this panel is then called in the onModuleLoad().

I have window with few widgets inside. When it is rendered, it shows in top left corner for a second and then is centered. Is there any chance to lazy rendering? I mean that window is centered first and then child widgets are rendered. Or maybe I can hide window content behind mask during it is rendered? ...
Hi, I am trying to add click event to one of the widgets that use gwt-connector. Here is the code: public class Diagrams extends Diagram implements HasClickHandlers{ public Diagrams(AbsolutePanel boundaryPanel) { super(boundaryPanel); } @Override public HandlerRegistration addClickHandler(ClickHandler handler)...
So, I have a GWT client, which interacts with a Python Google App Engine server. The client makes request to server resources, the server responds in JSON. It is simple, no RPC or anything like that. I am using Eclipse to develop my GWT code. I have GWTTestCase test that I would like to run. Unfortunately, I have no idea how to actuall...
I am evaluating whether to use SmartGWT, and have no prior experience with it. I have one particular question on the Calendar widget. When you go to a airline/car rental website, and you need to specify the day of the month to make the booking, they pop up a month calendar which the customer-user could click forward/previous month to se...
I'm writing an application in GWT. It went really well, until I ran it in IE. I made an application that uses a FlexTable, and each cell of the table was to be highlighted. I wrote the MouseOver handler, but in the Internet Explorer it works incredibly slow. Is there anything I can do about it? ...
Hello! I am trying to get a proper method for days to select multiple cells in a flextable's column. So far i only managed to do it with clicks which works well, but a drag selection would be much better. I have been reading docs and searching, but all the stuff i found was based on deprecated code. I use GWT 2.0 . I know i need some ...
Hi, I've been using GWT for quite some time now and have only used the eclipse plugin to compile my projects so far. Due to a new requirement I need to use an ant build (for the first time) to build a gwt project. First I'll say that I have 2 modules which have an entry point and 2 other common modules which only contain java classes (wh...

Hello, I am trying to work out how to send a domain object from the server-side to the client-side using GWT RPC. I've coded a really simple use case that represents the sort of thing I (and others?) need to be able to do but presently can't get to work. I have scoured the docs, tutorials and forums but they either show Strings being p...
I'm using com.google.gwt.i18n.client.timezone to try and display a date (as at the server), but GWT automatically adds the current timezone to the date when formatting it, meaning The wrong date is shown in different timezones. To combat this, I'm sending the server's timezone offset to the client and using that when formatting. I live...
Hi, I am using GWT-Graphics to create shapes like rectangle, circles etc... Now i am trying to add text to these shapes. Here is how the code looks like: DrawingArea d1 = new DrawingArea(100, 100); Ellipse e = new Ellipse(29, 20, 30, 20); Text t = new Text(10, 20, "A"); d1.add(e); d1.add(t); boundaryPanel.add(d1, 200, 40 ); But when ...
What is the difference between GWT.create(SomeClass.class) and new SomeClass()? Why would you use one over the other? ...
Hi I need some configuration files, that can be changed without recompiling the project in my GWT application. However, the GWT i18n doesn't allow to be used serverside. So what's the solution for getting configuration constants to be used serverside? Thanks. ...
