Hello,
thanks for the answer, Scott.
Its confusing. For example, as suggested by you:
@Singleton
public class MyFactory {
@Produces
public SearchService searchService() { ... }
}
SearchFilter implements Filter {
@Inject SearchService service;
public void doFilter(req,resp) {...}
}
}
1) I get an exception:
Can't find a bean for 'class ServiceService'
Do i need to register the MyFactory anywhere manually?
2)
I have a listener, that starts/stops the ComponentProvider (like pico) and
put/removes it into/from the servlet context.
Can MyFactory already be given the @inject ServletContext"? So that
filters/servlets can be given @inject stuff from MyFactory, that would now
implicitly depend on ServletContext?
3)
Do i really have to write explicitly, what MyFactory can produce? I have
hundreds of components in my provider, that potentially could be used.
I would like to be able to define a chain, like, look first in my own
ComponentProvider, and then maybe lookup somewhere else.
Hm. That all is very confusing. :-)
Thx
