我正在一个EJB 3无状态会话bean中使用Jersey客户端。我可以在Weblogic 11g上部署EJB项目。但是当我尝试从JSP查找bean时，我会收到以下错误：

我对EJB 3、Jersey和Weblogic都不熟悉。据我了解，无状态会话bean无法找到Jersey Client类。请问有谁能帮助我？
我在OEPE（Oracle Enterprise Pack for Eclipse）中有两个项目。一个是EJB 3.0项目，其中包含无状态会话bean；另一个是动态Web项目，其中包含JSP，我在其中进行JNDI查找以获取无状态会话bean。我在无状态会话bean的一个方法中使用Jersey Client类。这个方法是从JSP中调用的。
当我使用管理员控制台检查服务器上的部署时，会发现有两个部署。一个是OEPE自动生成的EAR，对应于动态Web项目。另一种部署类型是EJB。
我还尝试将jersey jar文件添加到服务器下的lib文件夹中并重新启动服务器，但仍然遇到相同的错误。
