How to consume a java SOAP Web Service that requires User and Password?

Question

I am trying to consume a SOAP web service using Netbeans IDE (JAVA), but when I try to delete a list it returns null to me.

Talking to a colleague, he told me that it is for lack the user and network password of the company I work, however I am having difficulties to understand this process, since how can I pass this information to the web service that I am consuming.

I have to pass this information in another way?

Below goes with data for analysis;

SOAP Web Service made in Sharepoint;

Class where the lists are.

import javax.xml.bind.annotation.XmlType;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "listName"
})
@XmlRootElement(name = "GetList")
public class GetList {

    protected String listName;

    /**

     * 
     * @return
     *     possible object is

     */
    public String getListName() {
        return listName;
    }

    /**
     * Sets the value of the listName property.
     * 
     * @param value

     *     
     */
    public void setListName(String value) {
        this.listName = value;
    }

}

Class to call List.

package Wss;

import java.util.ArrayList;
import java.util.List;
import vamoLA.GetListResponse.GetListResult;

public class Testando {

    private String username;

    private String password;

    public static void main(String[] args) {
        
        GetListResult list = getList("T_CARDAPIO_PRATO");
        List<Object> content;
        content = new ArrayList<Object>();
        content = list.getContent();
        System.out.println("Resultado 1 " + content.get(0));

    }

    private static GetListResult getList(java.lang.String listName) {
        vamoLA.Lists service = new vamoLA.Lists();
        vamoLA.ListsSoap port = service.getListsSoap();
        return port.getList(listName);
    }
    
    
    

}
