java - 将 Liferay jersey portlet 部署到 Tomcat 会抛出异常 java.lang.ClassNotFoundException : com. sun.jersey.spi.container.servlet.ServletContainer

Question

我似乎在将我的 portlet war 部署到 Liferay 服务器时抛出 java.lang.ClassNotFoundException，在 eclipse (Indigo) 中运行服务器时也会发生这种情况。在将它转换为 Liferay portlet 之前，我确保我的 Jersey 服务在 Tomcat 7.1 上工作。谢谢。

我的 WebService 类看起来像

@Path("/mymessage")
public class WebService
{
       @GET
       @Path("hello")
       @Produces(MediaType.APPLICATION_JSON)
       public String myMethod()
      {   
             return "HELLO";
      }
}

我的 web.xml 看起来像

问题是我正在部署一个使用 Liferay 插件构建的 Liferay portlet，我已将其转换为 Maven 项目，而插件部署没有获取 Maven 依赖项。
