webservice报Error reading XMLStreamReader异常

[xubtice]

String endpoint = "a?wsdl";

			Service service = new Service();

			Call call = (Call) service.createCall();
			call.setTargetEndpointAddress(endpoint);
			call.setOperationName("FechZWD");

			call.addParameter("CC", org.apache.axis.encoding.XMLType.XSD_DATE,
					javax.xml.rpc.ParameterMode.IN);
			call.addParameter("CZ", org.apache.axis.encoding.XMLType.XSD_DATE,
					javax.xml.rpc.ParameterMode.IN);

			SOAPHeaderElement soapHeaderElement = new SOAPHeaderElement(
					new javax.xml.namespace.QName(
							"as"),
					"SMSSoapHeader");
			soapHeaderElement
					.setNamespaceURI("a");
			soapHeaderElement.setObjectValue(null);
			soapHeaderElement.addChildElement("Username").setValue("Username");
			soapHeaderElement.addChildElement("Password").setValue("Password");
			call.addHeader(soapHeaderElement);
			call.setUsername("Username");
			call.setPassword("Password");
			
			  
			call.setReturnType(org.apache.axis.encoding.XMLType.XSD_SCHEMA);

			 

			Object[] params = new Object[2];
			params[0] = "a";
			params[1] = "b";
			Object res = call.invoke(params);
			Schema schema = (Schema) res;

在 Object res = call.invoke(params); 报Error reading XMLStreamReader.
