HI! I've solved the error before. I execute the wsprovide in the build directory instead of the build\service directory and change the command like this: $c:\jboss\wsprovide -t -o generated -w service. IContar service.Contar But know I've got another error: java.lang.NoClassDefFoundError: javax/ejb/Stateless I don't implement EJB. This could be the problem? I put here the code of my classes: IContar package service; | | import java.rmi.Remote; | import java.rmi.RemoteException; | | import javax.jws.WebMethod; | import javax.jws.WebResult; | import javax.jws.WebService; | import javax.jws.WebParam; | | import org.osid.OsidContext; | | import util.DatePalabra; | | @WebService( | name="IContar", // wsdl:portType | targetNamespace="urn:service" //wsdl:targetNamespace | ) | public interface IContar extends Remote { | | @WebMethod | @WebResult(name="IContar_darCuentaResponse") | public DatePalabra darCuenta(@WebParam(name = "ctx", partName ="ctx") OsidContext ctx) throws RemoteException; | } | | Contar package service; import java.rmi.RemoteException; import javax.jws.WebService; import javax.jws.soap.SOAPBinding; import org.osid.OsidContext; import org.osid.OsidException; import util.DatePalabra; @WebService( serviceName="Contar", // wsdl:service portName= "IContarPort", //wsdl:port name=... binding=... endpointInterface = "service.IContar", //nombre de la interficie del WebService targetNamespace="urn:service", //wsdl:targetNamespace wsdlLocation = "WEB-INF/wsdl/Contar.wsdl" //nombre y ubicación en el proyecto del fichero .wsdl ) @SOAPBinding( style=SOAPBinding.Style.RPC, use=SOAPBinding.Use.LITERAL ) public class Contar implements IContar{ public DatePalabra darCuenta(OsidContext ctx) throws RemoteException { DatePalabra dp = new DatePalabra(); try { String str = (String) ctx.getContext("iduser"); dp.setPalabra(str); dp.setLongitud(Integer.toString(str.length())); return dp; } catch (OsidException e) { // TODO Auto-generated catch block e.printStackTrace(); dp.setLongitud("0"); dp.setPalabra("vacio"); return dp; } } } Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4093032#...
