프로그램에서 servlet이 필요하여 provided (group: 'javax.servlet', name: 'servlet-api', version:'2.5')와 같은 방법등으로 servlet api를 사용하는데 이렇게 되면 필요한 jar가 만들어지고 다른곳에서 만들어진jar를 쓸때 servlet관련 경고가 발생하면서 만들어진jar 전체를 사용하지 못하는 문제가 발생한다.

이때는 tomcat설치 위치 밑에 lib로 가서 servlet-api.jar를 복사하여 java가 설치된 위치의 jre/lib/ext에 복사해준다. 이렇게 하면 client에서 별도로 가지고 있지 않아도 전체적으로 servlet-api.jar에 있는 클래스를 사용할 수 있게된다.

*참고

정보: validateJarFile(C:devworkspace.metadata.pluginsorg.eclipse.wst.server.coretmp4wtpwebappssda2WEB-INFlibsda-common-2.0.0-SNAPSHOT.jar) - jar not loaded. See Servlet Spec 3.0, section 10.7.2. Offending class:javax/servlet/Servlet.class라는 부분을 보면 servlet.class만 등록되지 않는다고 했으나 "com.gooper.comm.logger.LoggerAspect"를 포함하는 test-common-2.0.0-SNAPSHOT.jar 전체가 등록되지 않아서 class를 찾지 못하는 오류가 발생하고 있다.
