  128.  原因: 使用向导创建web工程时 自动在 web.xml文件内生成了一个Servlet的 <servlet-name>JAX-RS Servlet</servlet-name>
  130. <servlet>
  131.     <description>JAX-RS Tools Generated - Do not modify</description>
  132.     <servlet-name>JAX-RS Servlet</servlet-name>
  133.     <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
  134.     <load-on-startup>1</load-on-startup>
  135.   </servlet>
  136.   <servlet-mapping>
  137.     <servlet-name>JAX-RS Servlet</servlet-name>
  138.     <url-pattern>/jaxrs/*</url-pattern>
  139.   </servlet-mapping>

解决办法: 将创捷ServServlet生成的删除即可
