Create java classes from an xml schema

The point is to make a simple white-pages web service which adds a person to a phone book (called addPerson() ) using SOAP. If there is already a person with the same first- and last name in the phone book, a fault message should be returned.

I made the following wsdl file

 <?xml version="1.0" encoding="UTF-8"?>
<definitions name="whitepages" targetNamespace="http://whitepages.ws"
    xmlns="http://ift.tt/LcBaVt"
    xmlns:wsdl="http://ift.tt/LcBaVt"
    xmlns:xsd="http://ift.tt/tphNwY" xmlns:tns="http://whitepages.ws" xmlns:soap="http://ift.tt/KIQHA2">
    <types>
        <xsd:schema targetNamespace="http://whitepages.ws" xmlns:tns="http://whitepages.ws">
            <xsd:complexType name="personType">
                <xsd:sequence>
                    <xsd:element name="address" type="tns:addressType"></xsd:element>
                </xsd:sequence>
                <xsd:attribute name="firstName" type="xsd:string"/>
                <xsd:attribute name="lastName" type="xsd:string"/>
                <xsd:attribute name="phone" type="xsd:string"/>

            </xsd:complexType>

            </output>
            <fault name="fault1">
                <soap:fault name="fault1" use="literal"/>
            </fault>
        </operation>
    </binding>
    <service name="whitepagesService">
        <port name="whitepagesBindingPort" binding="tns:whitepagesBinding">
            <soap:address location="http://localhost:${HttpDefaultPort}/service"/>
        </port>
    </service>
</definitions>

I validated the xml and now I need to make the java classes(for both) for that schema but I don't know how to proceed...Any advice or tip would be really appreciated..

Thanks in advance
