I'm studying web services, and I developed this simple one:
WebServiceBean.java
| /**
| * @ejb.bean
| * name="WebService"
| * jndi-name="ejb/publishingsystem/dipartimento/WebService"
| * type = "Stateless"
| * display-name = "WebService"
| * description = "WebService Session EJB"
| * view-type="service-endpoint"
| *
| * @ejb.interface
| *
service-endpoint-class="publishingsystem.dipartimento.interfaces.WebServiceEndpoint"
| *
| * @wsee.port-component
| * name="WebServiceEndpointPort"
| *
| */
| public class WebServiceBean implements SessionBean {
| private Dipartimento dip;
|
| /**
| * Hello world business interface method.
| *
| * @ejb.interface-method view-type = "service-endpoint"
| */
| public java.lang.String sayHello(String name)
| {
| return("Hello " + name);
| }
|
|
| public WebServiceBean() { super(); }
|
| public void setSessionContext(SessionContext ctx)
| throws EJBException, RemoteException {}
|
| public void ejbRemove() throws EJBException, RemoteException {}
| public void ejbActivate() throws EJBException, RemoteException {}
| public void ejbPassivate() throws EJBException, RemoteException {}
|
| /**
| * Default create method
| *
| * @throws CreateException
| * @ejb.create-method
| */
| public void ejbCreate() throws CreateException {}
|
| }
|
I used wstools with this configuration file:
<configuration xmlns="http://www.jboss.org/jbossws-tools">
| <java-wsdl>
| <service name="WebService" style="rpc"
endpoint="publishingsystem.dipartimento.interfaces.WebServiceEndpoint"/>
| <namespaces target-namespace="http://www.unibo.it/dip"
| type-namespace="http://www.unibo.it/dip/types"/>
| <mapping file="jaxrpc-mapping.xml"/>
| <webservices ejb-link="WebServiceBean"/>
| </java-wsdl>
| </configuration>
|
...and I obtained the following files:
WebService.wsdl

I created the jar package (with these 3 files in META-INF) and I tried to deploy it in
JBoss, but it returns the following error:

What does it mean? What's wrong with my code? Did I forget something writing the web
service?
Thanks a lot.
