Tomcat 서블릿 ClassNotFoundException

간단한 서블릿을 만들었습니다.Tomcat 서블릿 ClassNotFoundException

package servlets; 

import javax.servlet.ServletException; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import java.io.IOException; 
import java.io.PrintWriter; 

public class testServlet extends HttpServlet { 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     PrintWriter out = response.getWriter(); 
     out.print("TEST"); 
     out.close(); 
    } 

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 

    } 
}

web.xml을 구성

<servlet> 
     <servlet-name>testServlet</servlet-name> 
     <servlet-class>servlets.testServlet</servlet-class> 
     <load-on-startup>3</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>testServlet</servlet-name> 
     <url-pattern>/test</url-pattern> 
    </servlet-mapping>

왜 실수가?

서블릿이 클래스 경로에 있습니까? –

는이 파일이 있어야합니다 :

의 webapps/WEB-INF/클래스/서블릿/대신 낙타 케이스의 파스칼 경우와 클래스의 이름을하시기 바랍니다 말했다 testServlet.class

- TestServlet

IntelliJ IDEA를 사용합니다. 나쁘게 배포를 구성했습니다. 화면을 참조하십시오. ! – BILL

@BILL과 같은 서블릿의 모습을 어떻게하는지? – Bozho

기존 서블릿을 만들거나 편집 할 때마다 .war 파일을 다시 WebApps 폴더로 내 보내야합니다.
생성 된 서블릿 클래스가/WEB-INF/CLASSES 아래에있을 필요는 없지만 패키지 아래에 만들어야합니다.
web.xml 파일의 xxxx.jsp에서이 servlet 클래스를 사용하는 .jsp 파일이 참조되는지 확인하십시오.
