getClass().getResourceAsStream("/config.txt");
It returns null if the file can't be found. if you place the
config-file in the same package as the class reading it, you
can leave away the slash.

Just to reiterate, I would like best to find a way to obtain the base
path for the web application that lives inside the war.
@Lothar:
Thanks for the tip; I am calling getClass().getResourceAsStream
("config.txt") from ServiceImpl.java in the server package. It works
when I put config.txt in the server package, but I was hoping to put
it in the war in the same place as the main .html file, on the same
level where /WEB-INF resides. If I try getClass().getResourceAsStream
("/config.txt") however, I get a null. Any idea what I might be doing
wrong?
@Mariyan:
This is a file that the server needs to load that the client knows
nothing about. I am new to java web application development though, so
I am open to suggestions about best practices. I've read about
properties files in XML that reside on the server but I can't find how
to set them up. I suppose I could manually add a property for the
correct path if I can't programatically determine it.

The way I'm getting around the issue is by calling
String root = getServletContext().getRealPath("/");
after the server has initialized (i.e. outside ServiceImpl.java's
constructor). Apparently you simply cannot get the ServletContext in
the constructor of ServiceImpl? I suppose that makes sense.

I don't agree about the separation of concerns factor with GWT-RPC.
GWT has gone to great lengths (to the point of being annoying in my
case) to ensure that a developer knows exactly where the code is that
is being written.
As far as the RPC vs RESTful debate, I think most everyone would agree
that REST is better from an abstract interface perspective. However,
in many cases RPC is faster to develop in, GWT RPC is a faster
transport, and makes life easier than json and overlay types. This is,
of course, IMHO.
Not that I'm saying GWT-RPC is a silver bullet. I'm just saying if the
following are true for you, then GWT-RPC may be good for you:
(1) My GWT-based webapp is (and will always be) the only consumer of
my server resources (i.e. servlets)
(2) A Java server will always be used
(3) In a tradeoff between perfect design and perfect performance, I
tend towards performance.

This is a bug. The List<List<Object>> return type is causing the compiler to
generate serialization code for any class X that extends List<T>, where T is
an interface that has a implementing class that extends class X. The
following code will reproduce the issue:
@Deprecated
public class MyTest extends java.util.ArrayList<MyTestInterface>{}
public class MyTestInterfaceImpl extends MyTest implements MyTestInterface
{}
public class MyTestInterfaceImpl extends MyTest implements MyTestInterface
{}
Could you add a bug to the GWT issue
tracker<http://code.google.com/p/google-web-toolkit/issues/list>
?

Hi,
I would like to add object to a suggest box, and when selected I would
like to get the object.
Is it possible?
My problem is that I have a some DTO, that have and id and a
description, but the description is not unique:
so, in the suggest I have some description repeated (and this is ok),
but when I get the selection I would like to know exactly what object
was chose...
Is it possible?
Thanks, bye

I would suggest using addStyleName(), as it will allow you to tweak the look
and feel, and still leverage all of the existing DecoratorPanel CSS. The
following code worked for me:
public ContactsView() {
DecoratorPanel contentTableDecorator = new DecoratorPanel();
initWidget(contentTableDecorator);
contentTableDecorator.addStyleName("orangeOutline");
...
}
With this CSS:
.orangeOutline {
border-style: solid;
border-width:1;
border-color: #CC6600;
}
.gwt-DecoratorPanel .middleCenter {
height: 100%;
width: 100%;
}

In my experience, the fewer components you have for a single view, the
easier it becomes to maintain code. With that being said, there are some
cases where it makes more sense to combine a large number of UI components
into a single view, but you certainly can have many views and many
presenters on screen at one time.
The way that I allow this is to have a MainPresenter and MainView. The main
view has several components that remain bound (exist in visible form within
the UI) regardless of the state of the application, and the MainPresenter
initializes all other presenters in my application. It determines what view
is shown with a number onEvent methods.

Yaakov,
Having multiple presenters driving a single view would be a bit strange.
Typically want to the presenter to define the display interface that the
view will implement. Having multiple presenters drive a single view means
that either a) the display interface is defined in some parent presenter
class, or b) one of the presenters is responsible for defining the display
interface. Either way, it decouples the presenter->display relationship that
is inherent to the MVP architecture.
For applications with large UI frontends, you could consider breaking the UI
up into smaller presenter/view pairs that are managed by some controller
class. Take for example Gmail; the folder list would be one presenter with
an associated view, the inbox list another, the Google Talk interface
another, and so on. All of these would then be managed by some
MainViewController class.
Keeping widget-based code out of the presenter for ease of testing is
golden. Beyond that it's really a question how much code you want to
maintain within a single presenter and view.

Hi Chris
Thanks for you input around the dividing of presenters and views in bigger
apps like Gmail.
Do you have any brief input on how runAsync and MVP play together?

Couple of diagnostic questions:
1. What version of Windows are you running (Vista, Windows 7, etc...)?
2. I'm assuming 32 bit architecture and not 64 bit. Is this correct?
3. What project are you trying to compile (custom or one of the samples)?
4. What do you see in the Eclipse log file (workspace/.metadata/.log)?
Regarding browsers connecting to port 9997, have you tried changing the
codesvr URL to reference "localhost" and not your assigned IP?

It's probably too late since it sounds like your project is quite far
down the line, if it was at its early stage, I'd recommend using
Google Maps API from the gwt-google-api[1] project?

Hi,
Eclipse seems to use old versions of my test classes. When I add a
method to my test class, and run the test via "Run as -> GWT JUnit
Test" or "Run as -> GWT JUnit Test (production mode)" or "Run as ->
JUnit Test", Eclipse doesn't see the new test method. Same for
removing old test methods. Even after I restart Eclipse. Only if I go
to the command line and run "ant test.dev", Eclipse picks up the
updated version of the Test.
Maybe it has something to do with the fact that I used webAppCreator
(with the -junit option) to create the project, instead of creating it
with the Eclipse wizard?
Does anybody else have the same problem?
Thanks
Chris

The reason I asked whether you have GWT2.0 on your debian server is
that if you look at the error message, all missing classes are those
introduced in GWT 2.0, so my guess is that the GWT compile isn't
picking up the 2.0 gwt-user.jar
Are you using a different classpaths for the GWT compilation and the
Java compilation? You might want to check that.
