I understand. Its a question to Yoko developers. > If you use CORBA server & web services client as described in YOKO > ws\hello_world sample (i.e., the server is using CORBA binding, the client is > using SOAP or XML binding), Dispatch<Source> should definitely work, because > what sent on the wire is SOAP or XML message. You say you have CORBA service and WS client implemented with Dispatch<Source> should work? Or what you mean exactly with working Dispatch? Talking about WS client calling CORBA we have tried to use dynamic proxy over CORBA and it doesnt work: QName svcQname = new QName( "http://schemas.apache.org/yoko/idl/calc", "com.pikeelectronic.calc.CalculatorCORBAService"); QName portQName = new QName( "http://schemas.apache.org/yoko/idl/calc", "com.pikeelectronic.calc.CalculatorCORBAPort"); File wsdl = new File("calc-soapbinding.wsdl"); Service svc = Service.create(wsdl.toURL(),svcQname); ComPikeelectronicCalcCalculator calc = svc.getPort(portQName, ComPikeelectronicCalcCalculator.class); double result = calc.add(4, 5); System.out.println(result); When I run this with SOAP binding it works but when I try to do this with CORBA binding I am getting exception: INFO: Interceptor has thrown exception, unwinding now java.lang.NullPointerException at org.apache.yoko.bindings.corba.interceptors.CorbaStreamOutInterceptor.handleOutBoundMessage(CorbaStreamOutInterceptor.java:78) at org.apache.yoko.bindings.corba.interceptors.CorbaStreamOutInterceptor.handleMessage(CorbaStreamOutInterceptor.java:65) at org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:206) at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:253) at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:204) at org.apache.cxf.frontend.ClientProxy.invokeSync(ClientProxy.java:73) at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:134) at $Proxy34.add(Unknown Source) at com.pikeelectronic.calc.WSDIIClient.main(WSDIIClient.java:46) javax.xml.ws.WebServiceException: java.lang.NullPointerException at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:172) at $Proxy34.add(Unknown Source) at com.pikeelectronic.calc.WSDIIClient.main(WSDIIClient.java:46) Caused by: java.lang.NullPointerException at org.apache.yoko.bindings.corba.interceptors.CorbaStreamOutInterceptor.handleOutBoundMessage(CorbaStreamOutInterceptor.java:78) at org.apache.yoko.bindings.corba.interceptors.CorbaStreamOutInterceptor.handleMessage(CorbaStreamOutInterceptor.java:65) at org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:206) at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:253) at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:204) at org.apache.cxf.frontend.ClientProxy.invokeSync(ClientProxy.java:73) at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:134) ... 2 more > > Jervis > > -----Original Message----- > From: Lukas Zapletal [ mailto:[EMAIL PROTECTED] > Sent: 2007年8月2日 23:00 > To: cxf-user@incubator.apache.org; [EMAIL PROTECTED] > Subject: Re: YOKO & CXF CORBA Web Service using Provider<CorbaMessage> > > > Hello, > > the operation info and CORBA parameters are not the reason why do we > need the support.
