Clarification regarding getting a singleton instance in GUICE

[Keerthi K]

Hi,

I am trying to create a singleton instance per class loader instead of an
injector. I am fairly new to google guice and i am wondering if we can
create a singleton using google guice per class loader instead of an
injector?

Yes only one instance of key [Service] but not of key [ServiceImpl].
instance.

On another note, does the following code also generate one instance
per injector?
public class MyModule implements Module {
public void configure(Binder binder) {
binder.bind(Service.class)
.to(ServiceImpl.class)
.in(Scopes.SINGLETON);
}
}
From Guice's user guide.

That does help. Thanks!!

What I like about this group, I always learn something new, static
is
indeed per classloader:)

I don't understand what you are trying to achieve. Guice is all about injecting so you cannot have guice without an injector.

If you try to have Guice inject an instance depending on the current classloader you could try to write a scope which ensures one instance per classloader.
