Java JBoss 7-ResourceConfig实例不包含任何根资源类

我在JBoss 7.1中发布project.ear时遇到一些问题，它与WAS一起工作，并通过Eclipse直接发布到JBoss，但是当通过部署文件夹中的.ear或JBoss中的控制台发布时，我出现了错误“ResourceConfig实例不包含任何根资源类”

我已经尝试了几种解决这个问题的方法，但没有成功。我发现这个问题是可以解决的，但不知道如何解决

有人能给我解释一下纠正这个错误的步骤吗

这是我在web.xml中的servlet定义

<servlet>
    <servlet-name>Jersey Servlet</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
         <param-name>com.sun.jersey.config.property.packages</param-name>
         <param-value>com.xxxxx.webservices.rest</param-value>
    </init-param>
    <load-on-startup>2</load-on-startup>
</servlet>

当我对标记进行注释时，您在“当我对它进行注释时”中遗漏了一些内容，但我只需要将其限制在com.xxxxx.webservices.rest包中。当我对标记进行注释时，您在“当我对它进行注释时”中遗漏了一些内容，但我只需要将其限制在com.xxxxx.webservices.rest包中。
