我用CMP做了一个有关数据查询的程序，在FinderAll的方法里设定返回的值是Collection类型，在weblogic上部署后，在client程序里调用是，报如下的错：
java.rmi.RemoteException: SOAP Fault:javax.xml.rpc.soap.SOAPFaultException: Exception during processing: javax.ejb.EJBException: nested exception is: javax.naming.NameNotFoundException: While trying to look up comp/env/Students in /app/ejb/j2ee.jar#StudentSession.; remaining name 'comp/env/Students' (see Fault Detail for stacktrace)
