I have also tried dynamic proxy call:
QName operationQName = new QName(
"http://schemas.apache.org/yoko/idl/calc";,
"add");
JaxWsClientFactoryBean client = new JaxWsClientFactoryBean();
client.setAddress("http://localhost/soap/calc";);
client.setServiceClass(ComPikeelectronicCalcCalculator.class);
ClientImpl SOAPclient = (ClientImpl)client.create();
Object[] SOAPresult = null;
Object[] params = { new Double(4), new Double(2) };
try {
SOAPresult = SOAPclient.invoke(operationQName,
params);
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(SOAPresult);
I am getting the same result. Maybe I need to wrap the input
parameters (double, double) into Any type because it seems the CORBA
binding expects something else. Any pointers here?
Have a nice weekend.
