HTTP状态500 - 实例化servlet类的错误com.zeste de savoir.servlets.Test>

标签: java eclipse jsp tomcat

当我尝试在Eclipse上运行动态Web项目时收到错误消息。

文件web.xml位于WebContent / WEB-INF。

servlet已保存在Java Resources / src下,名称为" com.zestedesavoir.Test"并且servlet被命名为" Test.java"。

有servlet代码:

package com.zestedesavoir.servlets;

import javax.servlet.http.HttpServlet;

public class Test extends HttpServlet {

}

我运行http://localhost:8080/test/toto

时收到的错误消息下方

我多次尝试删除servlet并创建一个新的但我仍然收到相同的错误消息。

感谢您的帮助

您是否注意到班级名称末尾有一个奇怪的>字符?

该杂散字符位于堆栈跟踪中的异常消息和HTTP响应消息中(显然)。

在你的webapp配置的某个地方,你必须错误输入一个类名。我先检查“web.xml”文件,但它可能在其他地方。
