JSF에서 값을 가져 와서 bean으로 가져 오거나 그 반대로 가져 오는 JSF로 웹 응용 프로그램을 작성합니다. 내가 제대로 모든 것을 다했다 생각하지만 서버를 시작하고 2.0 프레임 워크페이지의 JSF 오류 - bean에 값을 가져 오거나 설정할 수 없습니다.
내가 JDK 1.6와 이클립스 헬리오스를 사용하고SEVERE: Servlet.service() for servlet [jsp] in context with path [/SimpleJSF] threw exception [/greeting.jsp (line: 20, column: 85) #{...} is not allowed in template text] with root cause
org.apache.jasper.JasperException: /greeting.jsp (line: 20, column: 85) #{...} is not allowed in template text
다음과 같은 오류를 얻을 첫 페이지, 아파치 톰캣 7 JSF에 액세스하려고 할 때

greeting.jsp 내 코드입니다
