Hi Johannes,
I think we can define a JerseyGuiceModule, from which you extend from,
that defines those bindings.
If you don't define a scope for:
@Provides
public WebApplication webApp( @NotNull GuiceContainer
guiceContainer ) {
WebComponent component = Reflection.field( "webComponent"
).ofType( WebComponent.class ).in( guiceContainer ).get();
WebApplication webApplication = Reflection.field( "application"
).ofType( WebApplication.class ).in( component ).get();
return webApplication;
}
it should work yes? Since Jersey is managing the scope of stuff to be
provided it is not necessary to declare a scope for any of the
@Provides methods you have defined.
There are some issues supporting injection of @*Param because of
restrictions in the Guice binding model. Modification of Guice will be
required.
Paul.
