최근 분산 환경에서 최적의 소프트웨어 개발 방법으로 각광받는 컴포넌트 기반 개발은 재사용성과 생산성 등의 이점으로 인하여 급변하는 IT분야의 시스템 구축에 적합한 방법으로 인식되고 있다. 그러나 새로운 시스템의 컴포넌트 기반 개발이 아닌 경우, 즉 기존 레거시 시스템을 컴포넌트 기반 시스템으로 변환하는 방법에 대한 연구는 미비한 상태이다. 본 논문에시는 기존 레거시 시스템에서 컴포넌트 기반 시스템으로 변환하기 위해 필요한 컴포넌트 추출을 위한 레거시 시스템 분석 기법을 제안하고, 이를 웹 어플리케이션에 적용하여 Servlet 프로그램에서 EJB 컴포넌트 추출 시 필요한 레거시 시스템 분석기로 서블릿 코드 분석기(Servlet Code Analyzer)에 대해 설명하겠다.
