Hi! I have a simple client of a web service implemented in java using eclipse with a plugging for JBossWS. In this client I use the library javax.xml.ws.* But when I run it the next problem appears: javax.xml.ws.WebServiceException: Provider com.sun.xml.ws.spi.ProviderImpl not found I put the libraries jaxws-api.jar and jaxb-api.jar in the build path of the project. Can you tell me what can I do? My client code is the next one: import java.net.URL; import javax.xml.namespace.QName; /*import javax.xml.rpc.Service; import javax.xml.rpc.ServiceFactory;*/ import javax.xml.ws.Service; import util.DatePalabra; import com.lasalle.util.resources.CollectionProperties; public class MainDevPalabra { public static void main( String[] args ) throws Exception { if( args.length < 1 ) { System.out.println( "Usage: Palabra name" ); System.exit( 0 ); } String argument = args[ 0 ]; DatePalabra dp = new DatePalabra(); //CollectionProperties propietats = new CollectionProperties(); String urlstr = CollectionProperties.getPropiedad("serviceD.url"); String nameServiceStr = CollectionProperties.getPropiedad("serviceD.name"); String namespaceServiceStr = CollectionProperties.getPropiedad("serviceD.namespace"); System.out.println( "Contacting webservice at " + urlstr ); URL url = new URL(urlstr); //se indican el namespace en el que se encuentra el servicio y su nombre //(esto se puede ver en el WSDL) QName qname = new QName(namespaceServiceStr, nameServiceStr); Service service = Service.create(url, qname); IContar age = ( IContar) service.getPort( IContar.class ); System.out.println( "age.age(" + argument + ")" ); dp = (DatePalabra) age.darCuenta(argument); System.out.println( "output longitud:" + dp.getLongitud() ); System.out.println( "output palabra:" + dp.getPalabra() ); } } Thanks.
