17장 에러

[나까치]

chap17장을 webapps 하단에 복사하면 제대로 실행이 됩니다.

그런데 chap17장을 ROOT 밑에 복사하고 에러없이 컴파일은 되었습니다.

글읽기에서 수정시 비밀번호를 잘못 입력하면 아래와 같은 에러가 발생합니다.

어디가 잘못된가요....

참고로 WritingRequest 와 ReplyingRequest 클래스가 model 에 있는데 책에는 service로 되어있네요.(컴파일은 제대로 되어있습니다.)

HTTP Status 500 - /chap17/update_error.jsp (line: 3, column: 0) "${updateException.class.simpleName}" contains invalid expression‎(s): javax.el.ELException: Failed to parse the expression‎ [${updateException.class.simpleName}]

JSP에서 ${updateException.class.simpleName} 를 ${updateException.getClass().simpleName}로 변경해주세요.
