【问题描述】：
我们正在使用 spring 来配置 jetty 并加载所有内容，我正在尝试将 jersey 用于 Web 服务并使用 jetty/spring 库，以便我可以将一些服务类自动连接到我的 jersey 资源中，但是我我无法启动服务器，因为它总是说ServletContext 为空。
这是我的 spring 配置 xml：
<property name="handler">
<bean id="handlers" class="org.eclipse.jetty.server.handler.HandlerList">
<property name="handlers">
<list>
<bean class="org.eclipse.jetty.servlet.ServletContextHandler">
<property name="eventListeners">
<list>
<bean class="org.springframework.web.context.ContextLoaderListener" />
<bean
class="org.springframework.web.context.request.RequestContextListener" />
</list>
</property>
<property name="initParams">
<map>
<entry>
<key>
<value>contextConfigLocation</value>
</key>
<value>classpath:applicationContext.xml</value>
</entry>
</map>
</property>
</bean>
<bean class="org.eclipse.jetty.servlet.ServletHandler">
<property name="servlets">
<list>
<bean class="org.eclipse.jetty.servlet.ServletHolder">
<property name="name" value="Jersey" />
<property name="servlet">
<bean
class="com.sun.jersey.spi.spring.container.servlet.SpringServlet" />
</property>
<property name="initParameters">
<map>
<entry>
<key>
<value>com.sun.jersey.config.property.packages</value>
</key>
<value>com.mycompany.ws.resource</value>
</entry>
<entry>
<key>
<value>contextConfigLocation</value>
</key>
<value>classpath:applicationContext.xml</value>
</entry>
</map>
</property>
</bean>
</list>
</property>
我按照此处的说明进行操作：http://blogs.oracle.com/enterprisetechtips/entry/jersey_and_spring 集成了 jersey 和 spring，但不同之处在于我有一个配置了 spring 的嵌入式码头服务器。
我不确定为什么我不断收到以下错误。我认为码头 ServletContextHandler 是他们文档中的 servlet 上下文。
