import java.net.MalformedURLException; 
import java.net.URISyntaxException; 

import javax.servlet.annotation.WebServlet; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest;

@WebServlet(urlPatterns = { "/main" }, loadOnStartup = 1) 
public class InitServlet extends HttpServlet { 

    private static final long serialVersionUID = 1L; 


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

     String actionn = request.getParameter("action").toLowerCase(); 
      if (actionn.equals("delete")) {

어제,하지만 오늘은 내가 프로젝트를 청소하고 업데이 트를했다

The requested resource is not available. /CCE/main 

(메이븐 프로젝트 업데이트)

: 메시지를 얻을 수

그럼에도 불구하고 나는 아무것도 바꾸지 않았지만이 컨텍스트 오류가 발생했습니다.

무엇이 잘못 되었나요?

Answer 1

이 문제점은 Eclipse 또는 Tomcat에서 프로젝트의 두 인스턴스를 실행하여 발생합니다. Eclipse 또는 Tomcat을 다시 시작하여이 문제점을 해결할 수 있습니다.
