현재 프로젝트가 개발은 Tomcat으로, 서버는 JEUS를 사용하고 있습니다. 이런 환경을 제가 만든건 아니고 ㅡ.ㅡ; EJB개발하는것도 아닌데 JEUS가 너무 무거우니 간단하게 그냥 tomcat가자는 다른분의 의견이 받아들여진 것이었죠.
Servlet spec 2.4를 기준으로 작업을 하니 웬만한건 양쪽다 먹는데 JNDI로 datasource를 가져오는 부분의 방법이 서로 틀리더군요.
Spring에서 datasource정의하는 부분도 JEUS, Tomcat용으로 따로 사용을 하곤 했죠.
이건 그냥 Spring 설정파일 바꾸는거니 그런대로 할만 했습니다.
그러다가 Spring+Ibatis조합을 안통하고 그냥 JDBC 코딩을 해야 될 상황이 생겼는데 이때는 무지하게 귀찮아지더군요. 컴파일을 새로해야 되니 너무 귀찮아서요.
Liferay라는 오픈소스를 보다 정답을 찾았죠. Server의 종류를 알아내는 방법이 있더군요.
ClassLoader.getSystemClassLoader().loadClass();을 이용하더군요.
허접한 개발자라 몰랐습니다. 이런방법이 있을줄..
다음은 그 클래스 소스입니다.
