JAX-WS duplicates complex type when generating wsdl

Question

I'm developing a web service with several methods taking as input identical complex data types. The data types have JAXB annotations and setters and getters, and the web service class has JAX-WS annotations.

Template of my service.java file:

@WebService(serviceName = "ServiceWS")
public class SericeWS {

private static ServiceIF serviceImpl;

static {
    serviceImpl = new ServiceImpl();
}

public Result Method1(Credentials credentials) {
        @WebParam(name = "credentials") Credentials credentials) { 

    return serviceImpl.Method1(credentials);
}

    public Result Method2(Credentials credentials) {
        @WebParam(name = "credentials") Credentials credentials) { 

    return serviceImpl.Method2(credentials);
}

}

EDIT: My Credentials.java file:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "name",
    "password"
})
@XmlRootElement(name = "Credentials")
public class Credentials implements MyBean {

    @XmlElement(required = true)
    protected String name;
    @XmlElement(required = true)
    protected String password;

    /**
     * Gets the value of the name property.
     * 
     * @return The name property of the credentials
     *     
     */
    public String getName() {
        return name;
    }

    /**
     * Sets the value of the name property.
     * 
     * @param value The name property of the credentials
     *     
     */
    public void setName(String value) {
       this.name = value;
    }

    /**
     * Gets the value of the password property.
     * 
     * @return The password property of the credentials
     *     
     */
    public String getPassword() {
        return password;
    }

    /**
     * Sets the value of the password property.
     * 
     * @param value The password property of the credentials
     *       
     */
    public void setPassword(String password) {
        this.password = password;
    }  
}

The service is deployed in Tomcat and the wsdl is auto-generated. When generating the client stubs with wsimport I get duplicate generation of the Credentials type (Credentials, Method1.Credentials and Method2.Credentials), i.e. a different (inner) class for each method.

It seems that the problem arrises when the wsdl and schema are generated :

<xs:schema xmlns:tns="http://service.my.package.com/"            
xmlns:xs="http://www.w3.org/2001/XMLSchema" version="1.0" 
targetNamespace="http://service.my.package.com/">
<xs:element name="Credentials">
 <xs:complexType>
  <xs:sequence>
   <xs:element name="name" type="xs:string"/>
   <xs:element name="password" type="xs:string"/>
  </xs:sequence>
 </xs:complexType>
</xs:element>  
....
<xs:complexType name="getLockBoxKeys">
 <xs:sequence>
  <xs:element name="credentials" minOccurs="0">
   <xs:complexType>
    <xs:sequence>
     <xs:element name="name" type="xs:string"/>
     <xs:element name="password" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>
 </xs:element>    
 .....

How can I make all this work such that I have only one definition of Credentials? I am quite new to web services, JAX-WS and JAXB so I'm not sure I have the annotations right.

Any help would be greatly appreciated.

Thanks for your answer. I've edited the original question to add the Credentials.java file. Let me know if you want to see anything else. — juniz

I'm not going to give a complete answer explaining all the rules, since I don't remember/understand them all.

But I think if you add the name element to your @XMLType annotation you'll get what you're looking for (or at least a bit further).

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

BTW, your original service.java file didn't seem to paste too cleanly (had some incorrect braces I think) making it hard for anyone to recreate.
