Hi everybody. Working with Google Web Toolkit (with Google Maps Extension) I got a little problem: I want to insert a Google Map into a TabLayoutPanel. Without that TabLayoutPanel everything worked fine. But as soon as the Map is inside of a tab it behaves really strange (its not centered right, and "jumps" when you try to scroll.). T...

Hello! Could anyone help me make normal layout in GWT. I need a main panel which: fills all the browser space (100% height); if being collapsed too much shows scroll bars (autoscroll).

I'm using GWT internationalization Messages. The documentation for Plural Forms says this should work: @DefaultMessage("{0} {1,number} hours {2}") @PluralText({"one", "an hour"}) String hours(String prefix, @PluralCount int count, String suffix); Well, it doesn't. Whatever value of count it still delivers DefaultMessage (e.g. "1 hours...

Does anybody know if it is possible to have a GWT-rpc call cause a file download prompt to appear without having to do a second request to a separate servlet?

I'm starting to get my feet wet in the latest Google Web Toolkit using the Eclipse plugin on OS X 10.5.8. So far I've been able to get the client up and running, which is great. The server, though, is a different matter. I'm trying to link to a .jar file that has some classes I want to use in a server ServiceImpl class, but it seems to ...

My custom callback class implements AsyncCallback (like MyAsyncCallback implements AsyncCallback) and planning use single instance of MyAsyncCallback for multiple rpc method executions.

I'd like to know if you guys have faced the same problem I'm facing, and how you are dealing with it. Sometimes, a small and harmless change in a Java class ensues strange errors at runtime. These errors only happen if BOTH conditions below are true: 1) the application is run on Google Chrome, and 2) the GWT JavaScript compiler outpu...
Has anyone successfully used the above statement to catch the exception before it goes to the browser as an alert?. I registered a custom Exception Handler in the first line of my application entry point.

I see that there are two ways of transferring objects from server to client Use the same domain object (Contact.java) as used in the service layer. (I do not use hibernate) Use the HashMap to send the domain object field values in the form of Map with the help of BeanUtilsBean class. For multiple objects, use the List>. Similary, use ...
I'm looking for a super simple JSON or YAML library (not particularly bothered which one) written in Java, and can be used in both GWT on the client, and in its original Java form on the server. What I'm trying to do is this: I have my models, which are shared between the client and the server, and these are the primary source of data i...

Hi all, I'm about to start developing a large-scale system and I'm struggling with which direction to proceed. I've done plenty of Java web apps before and I have plenty of experience with servlet containers and GWT and some experience with Spring.
