Hey folks,
I'm just getting started with Guice (and DI in general). I have a
question, hope it's not too dense.
I have a method that looks something like this in its first
incarnation (_predictors is a collection):
public boolean dispatch()
{
for( PredictorProfile predictor : _p
public DispatchHandler newInstance(PredictorProfile predictor) {
>> return new DispatchHandler(predictor, d1, ...);
>> }

Great, that's roughly how I was intending it to begin with, hence not
wanting another level of indirection in there really.
Nice one for putt
. Hope it helps.

Morning folks,
I have a custom provider for creating SoapDispatchHandler objects,
which implement an interface called DispatchHandler.
I want to set up a binding in my module such that any reference to
Provider is injected with an instance of
SoapDispatchHandlerProvider, the provider class which
Yep, working fine now, thanks Alen. This is my second week of Guice,
expect more silly questions :-)

Maybe I'm doing something stupid, but what's wrong with this picture:
// In my module RealServicesModule
bind( String.class ).annotatedWith(
FuncNetVersionDependent.class ).toInstance(
"http://cathdb.info/FuncNet_0_1/"; );
// A static member in my test class
@Inject @FuncNetVersi
PS This is using old-skool Guice 1.0 release, I'm hesitant to upgrade
while I'm still learning, but if this is a known issue then I can...
Cheers.
Andrew.

You mean initialize it as a static member itself or something?
private static Injector injector = Guice.createInjector( new
RealServicesModule() );

Morning folks, just FYI:
I accidentally bound an interface to an abstract class (forgot to
un-abstract it after some refactoring) and got an NPE in
BindingBuilderImpl$FactoryProxy:
com.google.inject.ProvisionException: Error while locating instance
bound to info.cathdb.funcnet_0_1.sessiondb.Re

Whoops, my bad for not checking. Thanks.
Andrew.

You received this mess
You can do this by binding List references annotated with
a particular marker annotation to a specific implementation of
List, which preloads itself with the required elements.
e.g. Set up annotations called @FileMenu, @EditMenu ... and Guice can
look for these and bind to the right preload
annotated with the appropriate annotations.
Or I might have completely misunderstood the problem :-)
Andrew.

Hi,
Does anyone know why I can't post to this group from a secondary,
non-gmail email address?
Google is aware that the address belongs to my account, because it
shows as a secondary address here
https://www.google.com/accounts/EditUserInfo and here
https://www.google.com/accounts/EditUserInfo .

There were some last month from someone at @nrc-cnrc.gc.ca ...

Hmm, having tried various combinations, the only way to make it work
if you're actually *using* gmail to send mail from your non-gmail
address, is to subscribe both accounts to the list. Otherwise it

How stable is Guice 2.0? Is there an estimated release date?

Simple answer: Stick to constructor injection. Then when the
constructor actually starts running, you know all the injection is
done.

Hi folks, I'm looking for a bit of advice here...
I'm building a JAX-WS Provider web service using the CXF toolkit. The
Provider class is created by CXF (actually via Spring but I don't use
Spring myself) via a no-arg constructor on starting the application.
NB When I say Provider in this message
PS I'm still using Guice 1.0 but I'm happy to upgrade if nearly-2.0
makes this easier...

but it
doesn't do much so it doesn't really need to be. And the real web
service provider can be tested with mocked-out dependencies without
using Guice.
If anyone has a better solution I'd be happy to hear it, but this
seems to work pretty well.
Andrew.
