Jetty 虚拟主机

Question

我正在尝试使用多个域配置 Jetty，我面临的问题是 Jetty 正在与另一个名为 SmartfoxServer 的服务器产品一起运行，所以我不确定是否可以按照我喜欢的方式进行配置。

这是我的jetty.xml：

<Configure id="Server" class="org.mortbay.jetty.Server">
    <!-- =========================================================== -->
    <!-- Server Thread Pool                                          -->

      <New class="org.mortbay.thread.QueuedThreadPool">
        <Set name="minThreads">10</Set>
        <Set name="maxThreads">200</Set>
        <Set name="lowThreads">20</Set>
        <Set name="SpawnOrShrinkAt">2</Set>
      </New>

      <!-- Optional Java 5 bounded threadpool with job queue

我有以下文件夹结构：

• 万维网/
• www/根/
• www/域名2/

localhost:8080 加载根/索引.html

本地主机：8080/domain2/加载 domain2/index.html

在根文件夹和 domain2 文件夹中，有这个 WEB-INF/web.xml 文件：

<web-app>
    <display-name>default</display-name>
    <description></description>

    <welcome-file-list>
        <welcome-file>index.py</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>    

    <error-page>
        <error-code>404</error-code>
        <location>/errors/404.htm</location>
    </error-page>

    <servlet>
        <servlet-name>DefaultServlet</servlet-name>
        <servlet-class>org.python.util.PyServlet</servlet-class>

        <init-param>
            <param-name>python.home</param-name>
            <param-value>./lib/</param-value>
        </init-param>

        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>DefaultServlet</servlet-name>
        <url-pattern>*.py</url-pattern>
    </servlet-mapping>

</web-app>

我尝试添加：

<Configure class="org.mortbay.jetty.webapp.WebAppContext">
  <Set name="contextPath">/www/domain2/</Set>
  <Set name="virtualHosts">
    <Array type="java.lang.String">
      <Item>domain2</Item>
    </Array>
  </Set>
</Configure>

到 web.xml 文件，然后使用http://域名2:8080，但这样做不起作用，我真的不确定这是否是正确的做法。此处的信息：http://docs.codehaus.org/display/JETTY/Virtual+hosts指的是战争，但我甚至没有战争。正如所说，我甚至不确定这是否可能，因为我在 SmartfoxServer 中使用 Jetty。感谢您的帮助。

好的我通过以下方式解决了它：

1. 创建与 www 文件夹同级别的 contexts 文件夹。
2. 在 contexts 文件夹中创建以下 domain2.xml 文件（不要忘记添加 xml 标头）

'将 xml 标头放在此处'

<!-- ==================================================================
Configure and deploy the test web application in $(jetty.home)/webapps/test

Note. If this file did not exist or used a context path other that /test
then the default configuration of jetty.xml would discover the test
webapplication with a WebAppDeployer.  By specifying a context in this
directory, additional configuration may be specified and hot deployments 
detected.
