Question

我正在尝试使用Liberty配置文件16.0.0.3调用远程EJB服务（MDM服务）。我的查找代码如下所示。

ctx = new InitialContext();
Object obj = 
        ctx.lookup("corbaname:iiop:myhost:9810/NameServiceServerRoot#com/dwl/base/requestHandler/beans/DWLServiceController");
        dwlServiceControllerHome = (DWLServiceControllerHome)PortableRemoteObject.narrow(obj, DWLServiceControllerHome.class);
        dwlServiceController = dwlServiceControllerHome.create();
        HashMap<String, String> contextMap = createContextMap();

        String response = dwlServiceController.processRequest(contextMap, wccReqString).toString().trim();  
                            try {
                                StringReader reader = new StringReader(response);                   
                                StreamSource streamSource = new StreamSource(reader);
                                tcrmResp = (TCRMService) providerMarshaller.unmarshal(streamSource);
                            } catch (Exception e) {

                                e.printStackTrace();

                                throw e;
                            }

使用上面的代码，我可以调用远程EJB服务。正面方案正常运行。当我们使用负面方案数据测试服务时（当远程EJB服务抛出自定义有效异常时）低于错误。

我们正在使用以下技术规格

Spring Boot 1.2.4 / 1.4.2
Liberty Profile 16.0.0.3
IBM JDK 8 / Sun JDK 8

Answer 1

“org.omg.CORBA.MARSHAL”说明了一切。两侧接口的定义（IDL）必须相同。如果不是，就会发生编组错误。可能你的代码没有返回异常的定义，或者定义与远程端的定义不同。

org.omg.CORBA.MARSHAL：Valuetype没有实现StreamableValue或CustomMarshal
