HTTP状态500 - 实例化servlet类Projekt.svs.usersView时出错

时间：2014-12-02 18:22:24

标签： java servlets

我在那里寻找这个问题，事实上 - 它有很多，但没有什么可以帮助我。这是我的项目结构的屏幕（如果有问题，请纠正我），web.xml的代码和使用的servlet，当然也有错误的内容。

enter image description here 

package Projekt.svs;

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 usersView extends HttpServlet {
    private static final long serialVersionUID = 1L;

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

        response.setContentType("text/html");

        PrintWriter out = response.getWriter();
        out.println("<html><body><h2>Hello World! Today is " + new java.util.Date() + "</h2></body></html>");
        out.close();
    }
}

type Exception report

message Error instantiating servlet class Projekt.svs.usersView

description The server encountered an internal error that prevented it from fulfilling this request.
