As a small follow-up, I'm posting a snippet of code that is capable of
using the web-service described in that wsdl.
It does so by using Axis2 RPC client..I wonder why this is working,
and why the cxf-generated classes are not.
import javax.xml.namespace.QName;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
public class HelloWorldClient {
public static void main(String[] args) throws AxisFault, Exception {
String url =
"http://localhost:8080/proactive/services/HelloWorldServer_Service";;
RPCServiceClient serviceClient = new RPCServiceClient();
Options options = serviceClient.getOptions();
EndpointReference targetEPR = new EndpointReference(url);
options.setTo(targetEPR);
QName op = new QName("helloWorld");
String textArg = "ProActive";
Object[] opArgs = new Object[] { textArg };
Class<?>[] returnTypes = new Class[] { String.class };
Object[] response = serviceClient.invokeBlocking(op, opArgs,
returnTypes);
String msg = (String) response[0];
System.err.println("Server returned: " + msg);
}
}
