Using ActiveMQ with Camel (Camel을 가지고 ActiveMQ 사용하기)

Using Spring-DM (Spring-DM 사용하기)

It is often easy to define two application contexts for spring-dm, it helps you re-use configuration in Junit tests and cleanly separates OSGi from the normal spring application contexts.
그건은 종종 spring-dm을 위한 두개의 어플리케이션 컨텍스트를 정의하는 것이 쉽고 그것은 당신이 JUnit 테스트에서 환경구성을 재사용하고 보통의 Spring 어플리케이션 컨텍스트들로 부터 OSGi를 깨끗하게 분리하는 것을 돕는다.

You define these files in a bundle by adding them to the classpath under META-INF/spring
당신은 번들에서 META-INF/spring 폴더 아래 클래스패스에 그것들을 추가 함으로써 그 파일들을 정의하라

번역자 주) 한번에 전체를 지정해주는 것이 아니라 jms Connection 의 경우 OSGi 에 구현해 두고 일반적인 어플리케이션에서는 그것을 ref로 참조한 Jms 컴포넌트를 사용하는 것을 말한다.
