Question

我按照此页面的教程。http://www.coreservlets.com/Apache-Tomcat-Tutorial/tomcat-7-with-eclipse.html下载了test-app zip文件。该文件工作正常。但是，当我尝试创建一个简单的helloworld Servlet时，它会产生404错误。我在论坛上也看到了相关的问题，但似乎没有人能解决这个问题。我正在使用tomcat7和java6 ee。我能够添加链接并访问静态网页纯HTML页面，但在我尝试访问servlet时获得404。这是我的servlet代码。

@WebServlet(name="LoginServlet1",urlPatterns={"/LoginServlet1"})

public class LoginServlet1 extends HttpServlet {
  public void doGet(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {


    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    out.println
      ("<!DOCTYPE html>\n" +
       "<html>\n" +
       "<head><title>A Test Servlet</title></head>\n" +
       "<body bgcolor=\"#fdf5e6\">\n" +
       "<h1>Test</h1>\n" +
       "<p>Simple servlet for testing.</p>\n" +
       "</body></html>");
  }


}

这是我的index.html

    <!DOCTYPE html>
<html>
<head><title>Test Web App for Tomcat 7 or Other Servlet 3.0 Container</title>
<link rel="stylesheet"
      href="./css/styles.css"
      type="text/css"/>
</head>
<body>
<table class="title">
  <tr><th>Test Web App for Tomcat 7</th></tr>
</table>
<p/>
<fieldset>
<ul>
  <li><a href="LoginServlet1">hello</a> The HelloWorld servlet that
      generates plain text.</li>
</ul>
</fieldset>
<p/>
</body></html>

这是启动时的控制台日志。

Answer 1

这里的一切似乎都很好。尝试删除服务器并创建一个新服务器...并运行该项目。 Tomcat确实表现得很奇怪。

简单的Tomcat / Servlets - 获取HTTP状态404
