에 U 감사

긴급. 그러나 서버는 com.jp.loginservlet이라는 클래스를 검색합니다.

<servlet> 
    <servlet-name>NewServlet</servlet-name> 
    <servlet-class>com.jp.loginservlet</servlet-class> 
</servlet>

이어야

<servlet> 
    <servlet-name>NewServlet</servlet-name> 
    <servlet-class>com.jp.NewServlet</servlet-class> 
</servlet>

편집 : 이 단지의 경우 : 당신이 "깨끗하고 빌드"시도 않았다 당신의 web.xml에

, 태그가? 대부분의 경우 문제가 해결됩니다.

예 ...하지만 방금 틀린 error.it을 게시했습니다. 다른 페이지의 오류였습니다. 그렇습니다. 오류는 깨끗하고 빌드하여 해결됩니다. –
