Re: Assistance required by a novice.

[Warren Tang]

Believe me WISIWYG is not a good way to start. 

Beginning with WISIWYG like editors (especially Microsoft's products) can 
make you do some tasks very quickly, at the price that you don't understand 
what you are doing. The generated code is usually of low quality, hard to 
read and against best practices. Inevitably something goes wrong, and it's 
time to look at the code, but you'll find it's hard because you never 
really understand it.

I'm not saying WISIWYG is wrong. Some can improve productivity with proper 
usage (especially for prototyping and for designers). But it should be in 
the right order - it's important to know what we are doing before going for 
it.

So, if you don't know Java (or Java like language such as C#) very well, I 
would suggest you begin by learning Java first. Then you can follow the 
StockWalker tutorial:

Re: future of gwt & who use gwt

[Warren Tang]

GWT is good at RIA, but not fit for CMS which values SEO. Actually SEO 
in all AJAX applications is a challenge. The solution provided by Google 
(#!) hasn't been adopted by other search engines.

I'm sure Dart will have some libs to deal with communicating down the

Re: future of gwt & who use gwt

[Warren Tang]

Another language, oh my...

The death of Go seems to me that Dart is just another experiment of Google. 
Whether it  will gain popularity or not is under question. Replacing GWT 
(Java) with something else will definitely drive away many java programmers, 
who are already overburdened by so many technologies and value making most 
of their existing skills.

IMHO. the possibility of Google getting rid of Java is low, but Dart is 
about future, maybe not the near future, maybe the day Java loses its prime 
time. It could also give Google a good position in negotiating web 
standards, as Google's eyes are on the web.

Re: a basic gwt-maven-plugin question

True. That's what the "Update Project Configuration" command is meant to 
do. So the settings needs to be in pom.xml for it to survive the 
command. This can be done with the "build-helper-maven-plugin":


org.codehaus.mojo
build-helper-maven-plugin
1.7


add-source

add-source



${project.build.directory}/generated-sources/apt

Maven - update project configuration does break things for me:

The missing module argument is the full name of your module, e.g.

Re: no "run as GWT application" in Eclipse 3.7 (indigo)

I noticed that "Run as Web Application" and "Run as GWT application" has 
different user interfaces - the former runs in an embedded window in eclipse 
while the latter runs as a standalone app. Does anyone know the differences? 


Besides, there is also a "Compile as GWT application" command in the full 
version of GWT Designer. I find it's easier to find than the toolbar button. 


I'd love a package command too, but for now I use Maven for packaging. An 
alternative is ant as described in the following articles in details:

Re: How can I get the "Expenses" sample up and running?

[Warren Tang]

Hi David,

I'm really thankful for your patience for answering this starter's 
question. 

I imported the project into eclipse from according to the readme file. Maven 
had an issue finding the gwt-servlet2.2.jar. I fixed it by changing the GWT 
version to 2.3.0 in pom.xml, and adding GWT SDK and Appengine SDK to the 
classpath. The project was then built successfully. But when I run it in the 
dev mode, the following error appears in eclipse's console view:

Exception in thread "main" java.lang.NoSuchMethodError:

I've no idea what it means. 

Besides, it should need my appengine credentials in order to fill data into 
appengine, right? How can I configure it?

How can I get the "Expenses" sample up and running?

[Warren Tang]

I have trouble to run the "Expenses" sample in GWT's samples folder. The 
sample appeared in Google I/O sessions a few times. 

I'm not familiar with App Engine, but this is what I've done:

   1. create an new Eclipse project and then overwrite the src and war with 
   those from the Expenses sample.
   2. add App Engine support and specified the application id/name I got by 
   creating a new application in appengine.google.com.
   3. compile "LoadExpensesDB.gwt.xml" (which I assume is used to fill 
   appengine with some sample data.).The permunations completed but at the 
   beginning of the log their are some errors:
   Compiling module com.google.gwt.sample.expenses.LoadExpensesDB
  Validating newly compiled units
 [ERROR] Errors in 
   
'file:/D:/work/learning/gwt/Expenses/java/com/google/gwt/sample/expenses/shared/EmployeeProxy.java'
[ERROR] Line 25:

[ERROR] Line 22: The import 
   com.google.gwt.sample.expenses.server.domain.Employee cannot be resolved
[ERROR] Line 29: Employee cannot be resolved to a type 
   ... ...
   4. When I run the module I got 
  HTTP ERROR: 503  SERVICE_UNAVAILABLE
   The log in hosted getty says:
   00:00:00.008 [WARN] failed GaeAuthFilter

Re: Need suggestions on supporting both Web and Desktop front-end.

[Warren Tang]

The info is quite valuable. Thanks.

BTW. The application shows blank page in IE9 but works fine in the latest 
Firefox and Chrome.

To Alain: By "run real java code" I mean the java code (business logic) 
should not be compiled to javascript (with the GWT compiler). Instead it 
should run natively on a JVM.

Re: Need suggestions on supporting both Web and Desktop front-end.

[Warren Tang]

I'll definitely check the Google IO videos. But I assume the new HTML5 
features won't work in legacy browsers like IE6? Anyway I don't think it 
can help me. The desktop application is offline (for a single user), but 
it should be able to execute *real* java code (not only javascript). I 
got the idea of embedding a local web server and the running my GWT 
application inside it from IRC.


Should I just go Swing as apposed to an offline GWT application (meaning 
"locally online" with an embedded web server in JRE)? Swing should do 
but the later could be much easier. I just don't know the difficulties 
of deploying such a GWT application running on an embedded web server. 
The end users is unskilled so the installation process should be as easy 
as possible. Are there any guides or should I try it out myself?

Don't forget that HTML5 brings with it a lot of support for offline 
apps: app cache, local storage, and the filesystem API 
(http://www.html5rocks.com/en/tutorials/file/filesystem/). GWT will 
auto-generate an app cache manifest for you via an app cache linker 
(see Chris Ramsdale's presentation on mobile apps with GWT from I/O 
this year), and GWT 2.3 offers the Local Storage API (also discussed 
in the same presentation).

As a said before, I never done that before (using RF from non-gwt
clients), but Thomas confirmed that it's possible.
Your app will carry the requestfactory-client.jar, I don't think
you need any server localy. You will need, of course, configure
the app to tell it where the RF server is located

Well, desktop apps are desktop apps. It's far easier to do things
like access filesystem, external devices, etc. If you don't depend
on such things, then I think your users will be ok with only the
gwt frontend

As for having  your businnes code on the client(desktop). No

the client. So if someone really really want to crack it he will.
If it s supposed to be the same application  running on 2

duplicating it ?

The desktop application works offline (do all the job
locally without ever connecting to a server). And the
business code can work with or without a database. So AIR
may not be the choice as I'm not so confident to compile
the business code into Javascript (AIR).

Need suggestions on supporting both Web and Desktop front-end.

[Warren Tang]

I need to build an application which has both a web font-end and a desktop 
front-end. There is a relational database. Lightweight frameworks are 
preferred. 
My previous project was done with SmartGWT + GWT + MyBatis. And it is the 
only java project I've done. 
Currently my thought is GWT + Spring + MyBatis. I also heard about 
SpringRoo. But the idea is quite vague for me. So could someone kindly make 
it clear for me? How can I use GWT + Swing/SwingRoo to support both the web 
and the desktop client, and reuse the business code? What else do I need? 
What's their roles?
