It turns out my binding was missing a to(Class<?>) statement.
binder.bind(Key.get(OptionsFilter.class,
Names.named("clinicsResource"))).in(Scopes.SINGLETON);
should have read:
binder.bind(Key.get(OptionsFilter.class,
Names.named("clinicsResource"))).to(OptionsFilter.class).in(Scopes.SINGLETON);
Question: shouldn't Guice issue some sort of warning in this case?
Thanks,

Hi,
I'm attempting to instantiate multiple instances of the same servlet
filter, with different filter parameters each time. Here is what I
did:
public class ServletConfiguration extends GuiceServletContextListener
implements Module
@Override
protected Injector getInjector()
{
return Guice.createInjector(new JerseyServletModule()
{
@Override
protected void configureServlets()
{
install(ServletConfiguration.this);
Map<String, String> corsParams =
Maps.newHashMap();
filter("/clinics").through(Key.get(OptionsFilter.class,
Names.named("clinicsResource")),
corsParams);
}
});
}
@Override
public void configure(Binder binder)
{
binder.bind(Key.get(OptionsFilter.class,
Names.named("clinicsResource"))).in(Scopes.SINGLETON);
}
}
I am getting this exception at runtime:
com.google.inject.CreationException: Guice creation errors:
1) No implementation for com.foo.OptionsFilter annotated with
@com.google.inject.name.Named(value=clinicsResource) was bound.
at com.foo.ServletConfiguration.configure(ServletConfiguration.java:
72)
1 error
Any ideas?
Thanks,
Gili
