1:17 a.m.
I have written a WebService on JBoss 4.0.4 GA (jboss-EJB-3.0_RC8-FD + jbossws-1.0.1.GA)
| package webservices;
|
| import java.rmi.Remote;
|
| public interface SimpleService extends Remote {
| String echo(String echo);
| }
|
| package webservices;
|
| import javax.ejb.Remote;
| import javax.ejb.Stateless;
| import javax.jws.WebMethod;
| import javax.jws.WebService;
|
| import org.jboss.ws.annotation.PortComponent;
|
| @WebService(name="EndpointInterface",
targetNamespace="http://localhost", serviceName="SimpleService")
| @PortComponent(contextRoot="/jbosswstest", urlPattern="/*")
| @Remote(SimpleService.class)
| @Stateless
| public class SimpleServiceImpl implements SimpleService {
| @WebMethod
| public String echo(String input) {
| return input;
| }
| }
|
After deploy it to JBoss, I got a auto-generated WSDL as follow:
| <definitions name='SimpleService'
targetNamespace='http://localhost'
xmlns='http://schemas.xmlsoap.org/wsdl/'
xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/'
xmlns:tns='http://localhost'
xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
| <types>
| <schema elementFormDefault='qualified'
targetNamespace='http://localhost'
xmlns='http://www.w3.org/2001/XMLSchema'
xmlns:soap11-enc='http://schemas.xmlsoap.org/soap/encoding/'
xmlns:tns='http://localhost'
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
| <complexType name='echo'>
| <sequence>
| <element name='String_1' nillable='true'
type='string'/>
| </sequence>
| </complexType>
| <complexType name='echoResponse'>
| <sequence>
| <element name='result' nillable='true'
type='string'/>
| </sequence>
| </complexType>
| <element name='echo' type='tns:echo'/>
| <element name='echoResponse' type='tns:echoResponse'/>
| </schema>
| </types>
| <message name='EndpointInterface_echo'>
| <part element='tns:echo' name='parameters'/>
| </message>
| <message name='EndpointInterface_echoResponse'>
| <part element='tns:echoResponse' name='result'/>
| </message>
| <portType name='EndpointInterface'>
| <operation name='echo'>
| <input message='tns:EndpointInterface_echo'/>
| <output message='tns:EndpointInterface_echoResponse'/>
| </operation>
| </portType>
| <binding name='EndpointInterfaceBinding'
type='tns:EndpointInterface'>
| <soap:binding style='document'
transport='http://schemas.xmlsoap.org/soap/http'/>
| <operation name='echo'>
| <soap:operation soapAction=''/>
| <input>
| <soap:body use='literal'/>
| </input>
| <output>
| <soap:body use='literal'/>
| </output>
| </operation>
| </binding>
| <service name='SimpleService'>
| <port binding='tns:EndpointInterfaceBinding'
name='EndpointInterfacePort'>
| <soap:address location='http://ibm-t40:8080/jbosswstest'/>
| </port>
| </service>
| </definitions>
|
Then I try to code a client to invoke the webservice:
| package client;
|
| import java.net.URL;
|
| import javax.xml.namespace.QName;
| import javax.xml.rpc.Service;
| import javax.xml.rpc.ServiceFactory;
|
| import webservices.SimpleService;
|
| public class SimpleServiceClient {
| private static final String _namespace = "http://localhost";
|
| private static final String _service = "SimpleService";
|
| private static final String _wsdl =
"http://localhost:8080/jbosswstest?wsdl";
|
| public static void main(String[] args) {
| try {
| URL defUrl = new URL(_wsdl);
| // Create the service factory
| ServiceFactory serviceFactory = ServiceFactory.newInstance();
| // Load the service implementation class
| Service remoteService = serviceFactory.createService(defUrl,
| new QName(_namespace, _service));
| // Load a proxy for our class
| SimpleService invoker = (SimpleService) remoteService
| .getPort(SimpleService.class);
| // Invoke our interface for each argument
| for (int i = 0; i < args.length; i++) {
| String returnedString = invoker.echo(args);
| System.out.println("sent string: " + args
| + ", received string: " + returnedString);
| }
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
| }
|
Here comes the problem ->
org.jboss.ws.WSException: Cannot obtain java type mapping for: {http://localhost}echo

Could somebody give me a idea what's wrong, thanks.
