Validation Failed. Creation Web Service Proxy

Question

Hi, all
I've got a problem with JDeveloper 10.1.3 when I try to create a web serviceproxy using the wizard.
My service class is next,
package swa;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.color.ColorSpace;
import java.awt.geom.AffineTransform;
import java.awt.image.AffineTransformOp;
import java.awt.image.BufferedImage;
import java.awt.image.ColorConvertOp;
import java.awt.image.RescaleOp;
import javax.xml.soap.AttachmentPart;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPMessage;
public class ImgToolbox {
public final static int FLIP_VERTICAL = 0;
public final static int FLIP_HORIZONTAL = 1;
public final static int FLIP_VERTICAL_HORIZONTAL = 2;
public AttachmentPart toGray(AttachmentPart imagen){
AttachmentPart apRetorno = null;
try{
Image image = (Image)imagen.getContent();
BufferedImage originalImage = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_INT_RGB);
ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
ColorConvertOp op = new ColorConvertOp(cs, null);
BufferedImage grayImage = op.filter(originalImage, null);
// Creación del AttachmentPart con la nueva imagen
MessageFactory mf = MessageFactory.newInstance();
SOAPMessage message = mf.createMessage();
apRetorno = message.createAttachmentPart();
apRetorno.setContent(Toolkit.getDefaultToolkit().createImage(grayImage.getSource()),"image/jpeg");
} catch(SOAPException e){
System.out.println("Error, en el mensaje SOAP.");
return apRetorno;
public AttachmentPart flip(AttachmentPart ap, int tipo){
AttachmentPart apRetorno = null;
try{
Image image = (Image)ap.getContent();
BufferedImage originalImage = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_INT_RGB);
AffineTransform tx = null;
AffineTransformOp op = null;
switch(tipo){
case FLIP_VERTICAL : {
tx = AffineTransform.getScaleInstance(1, -1);
tx.translate(0, -image.getHeight(null));
break;
case FLIP_HORIZONTAL : {
tx = AffineTransform.getScaleInstance(-1, 1);
tx.translate(-image.getWidth(null), 0);
break;
case FLIP_VERTICAL_HORIZONTAL : {
tx = AffineTransform.getScaleInstance(-1, -1);
tx.translate(-image.getWidth(null), -image.getHeight(null));
break;
op = new AffineTransformOp(tx, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
BufferedImage flipImage = op.filter(originalImage, null);
// Creación del AttachmentPart con la nueva imagen
MessageFactory mf = MessageFactory.newInstance();
SOAPMessage message = mf.createMessage();
apRetorno = message.createAttachmentPart();
apRetorno.setContent(Toolkit.getDefaultToolkit().createImage(flipImage.getSource()),"image/jpeg");
} catch (SOAPException e) {
System.out.println("Error, en el mensaje SOAP.");
return apRetorno;
public AttachmentPart resize(AttachmentPart img,float escala){
AttachmentPart apRetorno = null;
try{
Image image = (Image)img.getContent();
BufferedImage originalImage = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_INT_RGB);
// Se rellena la BufferedImage con la imagen original
Graphics g = originalImage.createGraphics();
g.drawImage(image, 0, 0, null);
g.dispose();
// Modificación de la imagen original
RescaleOp op = new RescaleOp(escala, 0, null);
BufferedImage tempImage = op.filter(originalImage, null);
// Creación del AttachmentPart con la nueva imagen
MessageFactory mf = MessageFactory.newInstance();
SOAPMessage message = mf.createMessage();
apRetorno = message.createAttachmentPart();
apRetorno.setContent(Toolkit.getDefaultToolkit().createImage(tempImage.getSource()),"image/jpeg");
} catch (SOAPException e) {
System.out.println("Error, en el mensaje SOAP.");
return apRetorno;
the wizard creates a JAX-RPC web service without problems from this class. However, if I click on "Regenerate Web Service from WSDL..." the method fails and throws a exception. The trace is next :

If I only expose the toGray method as a Web Service all works fine. Any combinatio with other methods won't work. It's very strange.
When I try to create a proxy using the wizard JDeveloper shows me next error message :
Validation Failed
...wsdl file does not contain sufficient information to create a proxy. At least one port type and a binding of the are required.
Any reply will be greatly appreciated.
Best regards.

I am getting this error by generating a web service from pl/sql procedure. Just one package, just one procedure. Error stack:
java.lang.NullPointerException
     at oracle.jdevimpl.webservices.generator.WrapperClassGenerator.generate(WrapperClassGenerator.java:262)
     at oracle.jdevimpl.webservices.generator.SPWebServiceGenerator$1.run(SPWebServiceGenerator.java:285)
     at oracle.ide.dialogs.ProgressBar.run(ProgressBar.java:551)
     at java.lang.Thread.run(Thread.java:595)
The pl/sql package header looks like this:
CREATE OR REPLACE package ADMIN.etis_autent as
procedure autent(
     ps_kasutajatunnus in varchar2,
     ps_parool in varchar2,
     ps_isikukood out varchar2,
     ps_eesnimi out varchar2,
     ps_perekonnanimi out varchar2
end etis_autent;
