[jersey-dev] Cannot @Inject into ExceptionMapper

[Martynas Jusevičius <martynas@xxxxxxxxxxxxx>]

Hi,

I'm attempting to inject some RequestScoped objects into an ExceptionMapper:

    public class NotFoundExceptionMapper extends ExceptionMapperBase
implements ExceptionMapper<NotFoundException>
    {

        @Inject TemplateCall templateCall;
    ...

In my ResourceConfig I have

    register(new AbstractBinder()
    {
        @Override
        protected void configure()
        {
            bindFactory(TemplateCallProvider.class).to(TemplateCall.class).
            proxy(true).proxyForSameScope(false).in(RequestScoped.class);
        }
    });
    ...
    register(new NotFoundExceptionMapper());
    // register(NotFoundExceptionMapper.class); // also tried this, same effect

However I get an error when NotFoundException should be mapped:

Looking at similar problems online, my guess is that it has to do with
a RequestScoped object being injected into Singleton. However I
haven't been able to find a solution yet.

Thanks.
