Pnum is the package name. You need Pnum to be a class for the code to compile.

Packages have classes inside them which you can instantiate; you cannot instantiate a package.

Agree.  I got my Netbeans reinstalled and generated the web service code just fine and is the package containing all the generated code for the service.  If you expand that you will see the EVDServis.java file and associated files.  Just make sure to go into that file and change the URL per instructions.

This is the final i think and it will work after i solv this last step :

code giving error for here :


 JAXBElement<PmumService.LoginMessage> el = new JAXBElement<PmumService.LoginMessage>(sv);
/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

package ginageldi;
/**

import PmumService.StringValue;
import javax.xml.bind.JAXBElement;
import javax.xml.namespace.QName;


public class Main {
    QName qName = new QName("http://tempuri.org", "Test");

public javax.xml.bind.JAXBElement<PmumService.LoginMessage> Mesaj() {
        PmumService.LoginMessage sv = new PmumService.LoginMessage() ;
        sv.setPassword(getPass());
        sv.setUserName(getUserName());
        JAXBElement<PmumService.LoginMessage> el = new JAXBElement<PmumService.LoginMessage>(sv);
        return el;
   }
    public JAXBElement<PmumService.StringValue> getUserName() {
        StringValue sv = new StringValue() ;
        sv.setV("example");
        JAXBElement<StringValue> el = new JAXBElement<StringValue>(qName, StringValue.class, null, sv);
        return el;
   }
    public JAXBElement<PmumService.StringValue> getPass() {
        StringValue sv = new StringValue() ;
        sv.setV("example");
        JAXBElement<StringValue> el = new JAXBElement<StringValue>(qName, StringValue.class, null, sv);
        return el;
   }

    public static void main(String[] args) {
            PmumService.Login cr = new PmumService.Login();
            cr.setLoginMessage(  new Main().Mesaj());
            try
            {
                javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance(cr.getClass().getPackage().getName());
                javax.xml.bind.Marshaller marshaller = jaxbCtx.createMarshaller();
                marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_ENCODING, "UTF-8"); //NOI18N
                marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
                marshaller.marshal(cr, System.out);
            } 
            catch (javax.xml.bind.JAXBException ex)
            {
                // XXXTODO Handle exception
                java.util.logging.Logger.getLogger("global").log(java.util.logging.Level.SEVERE, null, ex); //NOI18N
            }
    }

}

Wonderfull mwvisa :)

This is what i see on the output :

run:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:login xmlns:ns2="http://ws.dgpys.deloitte.com">
    <ns3:Test xmlns:ns3="http://tempuri.org">
        <ns3:Test v="example"/>
        <ns3:Test v="example"/>
    </ns3:Test>
</ns2:login>
BUILD SUCCESSFUL (total time: 1 second)

So how could i write the answer of service this is the end :)
I see that i send the required info. now i need to get only the answer :)
  public static void main(String[] args) {
            PmumService.Login cr = new PmumService.Login();
            cr.setLoginMessage(  new Main().Mesaj());
            try
            {
                javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance(cr.getClass().getPackage().getName());
                javax.xml.bind.Marshaller marshaller = jaxbCtx.createMarshaller();
                marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_ENCODING, "UTF-8"); //NOI18N
                marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
                marshaller.marshal(cr, System.out);
            } 
            catch (javax.xml.bind.JAXBException ex)
            {
                // XXXTODO Handle exception
                java.util.logging.Logger.getLogger("global").log(java.util.logging.Level.SEVERE, null, ex); //NOI18N
            }
    }

Not sure which of the different operations you need to do to accomplish what you are being asked to do.  I would look at the information provided by the service provider on the typical operations used.  Here is a tutorial on creating the WS client as you have completed the introduction which is getting the JAXB elements in place and tested.

             public void handleResponse(javax.xml.ws.Response<PmumService.Login> response) {
                 try {
                     System.out.println("Result = "+ response.get());
                 } catch(Exception ex) {
                 }

This is probably going to stray far from the question as stated here, so I would suggest awarding answer to a_b for pointing out you were using the package name as a class incorrectly which answers the question as stated and I will respond to login() method in your previous question which deals with that topic but using your new code since it would appear that is not completely answered.
