如何在Jetty中部署Servlet? [英] How do I deploy a Servlet in Jetty?

问题描述

我创建了一个想要在Jetty 7.2中部署的简单Servlet. Jetty正在运行，并且能够在http://localhost:8080/jonas/test.jsp上提供JSP页面.我用java -jar start.jar命令启动了Jetty.

我将编译后的Servlet MyServlet.class保存在<my_jetty_directory>/webapps/jonas/WEB-INF/classes/MyServlet.class上，然后尝试在http://localhost:8080/jonas/servlets/MyServlet上访问该Servlet，但是出现了HTTP 404错误.

HTTP ERROR 404

Problem accessing /jonas/servlet/MyServlet. Reason:

    Not Found

还有更多要做的事情吗?我应该在Jetty文件结构中的哪个位置放置MySerlvet.class?

---

我现在已经创建了一个简单的web.xml文件，并将其保存在<my_jetty_directory>/webapps/jonas/WEB-INF/web.xml中，然后重新启动了我的Jetty，但是它不起作用.这是我简单的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app>
  <servlet>
    <servlet-name>MyServlet</servlet-name>
    <servlet-class>MyServlet</servlet-class>
  </servlet>
</web-app>

我在JSP中遇到了类似的问题，现在已经解决:解决方案

您必须使用<servlet>和<servlet-mapping>在web.xml中映射您的servlet，如果使用servlet 3.0，则必须用@WebServlet对其进行注释. /p>

I have created a simple Servlet that I want to deploy in Jetty 7.2. Jetty is running and is able to serve JSP pages on http://localhost:8080/jonas/test.jsp. I started Jetty with the java -jar start.jar command.

I saved my compiled Servlet MyServlet.class at <my_jetty_directory>/webapps/jonas/WEB-INF/classes/MyServlet.class and then tried to access that Servlet on http://localhost:8080/jonas/servlets/MyServlet but I get a HTTP 404 error.

HTTP ERROR 404

Problem accessing /jonas/servlet/MyServlet. Reason:

    Not Found

Is there something more I have to do? Where in the Jetty file structure should I place MySerlvet.class?

I have now created a simple web.xml file and saved it in <my_jetty_directory>/webapps/jonas/WEB-INF/web.xml and restarted my Jetty, but it doesn't work. Here is my simple web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app>
  <servlet>
    <servlet-name>MyServlet</servlet-name>
    <servlet-class>MyServlet</servlet-class>
  </servlet>
</web-app>

I had a similar problem with JSP, that is solved now: How do I deploy a JSP file in the Jetty webserver?

解决方案

You have to map your servlet in web.xml, using <servlet> and <servlet-mapping>, or annotate it with @WebServlet if using servlet 3.0.
