在将我的 portlet 战争部署到 Liferay 服务器时，我似乎抛出了 java.lang.ClassNotFoundException，这也发生在 eclipse（Indigo）中运行服务器。在将其转换为 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

问题是我正在部署使用已转换为 Maven 项目的 Liferay 插件构建的 Liferay portlet，并且插件部署没有获取 Maven 依赖项。
