Question

我正在使用WAS服务器，我编写了一个java客户端，通过业务接口调用一个EJB，如下所示：

Hashtable<String, String> envJNDIProperties = new Hashtable<String, String>();
                        envJNDIProperties.put("javax.naming.factory.initial", "com.ibm.websphere.naming.WsnInitialContextFactory");
                        envJNDIProperties.put("java.naming.provider.url", "iiop://indmtx981:24121");
                        envJNDIProperties.put("java.naming.security.principal", myTicket);
                        envJNDIProperties.put("java.naming.security.credentials", "NA");
                        envJNDIProperties.put("org.omg.CORBA.ORBClass", "com.ibm.CORBA.iiop.ORB");

                        InitialContext initialCtx = new InitialContext(envJNDIProperties);

                        Object ejbObject = null;

/*
* Giving me error in following line
*/                         
SearchServicesRemoteBusiness remoteBusiness = (SearchServicesRemoteBusiness) initialCtx.lookup("amdocs-RM-Billing/CM-L1/SearchServicesBean!amdocs.csm3g.sessions.views.business.remote.SearchServicesRemoteBusiness");

                        System.out.println("Got referencve for: "+ ejbObject.getClass().getName());
//                      SearchServicesRemoteBusiness remoteBusiness = (SearchServicesRemoteBusiness) PortableRemoteObject.narrow(ejbObject,amdocs.csm3g.sessions.views.business.remote.SearchServicesRemoteBusiness.class);

                        AccountIdInfo accountId = new AccountIdInfo();

                        remoteBusiness.searchAccountById(accountId);

错误：

java.lang.ClassCastException：org.omg.stub.java.rmi._Remote_Stub无法强制转换为.SearchServicesRemoteBusiness 在EJBStandaloneClient.main（EJBStandaloneClient.java:27）

我尝试过：我使用createEJBStubs.sh为这个远程业务接口创建存根，并在运行时将此存根放在客户端类路径中，但错误仍然存在。欢迎提出任何建议。

Answer 1

致电PortableRemoteObject.narrow：

SearchServicesRemoteBusiness remoteBusiness = (SearchServicesRemoteBusiness)
    PortableRemoteObject.narrow(initialCtx.lookup("amdocs-RM-Billing/CM-L1/SearchServicesBean!amdocs.csm3g.sessions.views.business.remote.SearchServicesRemoteBusiness"),
    SearchServicesRemoteBusiness.class);

Answer 2

问题出现在我的类路径中，我给出了存根的完整类位置，而不应该在类路径中包含包结构。例如，我在目录x / y / z // stub.class中创建了存根。所以我们应该在类路径中使用x / y / z而不是x / y / z // stub.class。

我纠正了这个并且工作正常：）

java.lang.ClassCastException：org.omg.stub.java.rmi._Remote_Stub无法强制转换为<remote business =“”interface =“”name =“”> </remote>

错误：
