@Stateless
public class HelloService {
}
public class UserMgr {
@Inject
private HelloService hello;
public void doSomething() {

...
}
}
というように、スコープを付けた POJO を @Inject で Injection する。せいぜい @Named でインスタンスを使い分けるくらいpackage com.mycompany.cdiexam;

import javax.enterprise.inject.Produces;
import javax.enterprise.inject.spi.InjectionPoint;
import javax.inject.Named;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@Named
@Dependent
public class LoggerProducer {
@Produces
public Logger getLogger(InjectionPoint ip){
return LoggerFactory.getLogger(ip.getMember().getDeclaringClass().getName());
}
}

@WebServlet(name = "HelloServlet", urlPatterns = {"/HelloServlet"})
public class HelloServlet extends HttpServlet {
@Inject
private HelloCDI helloCdi;

throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
logger.info("Start Response");
/* TODO output your page here. You may use following sample code. */
out.println("<!DOCTYPE html>");

out.println("</body>");
out.println("</html>");
} finally {
logger.info("End Response");
out.close();
}

@Produces
public Logger getLogger(InjectionPoint ip){
の ip から injection する側の Object が取得できているきしだのはてな に曰く
