@XmlElement(required=true) for @WebParam does not work

Question

I\'m building web service using JAX-WS. I have a strange problem that the annotation @XmlElement(required=true) for @WebParam works in some @

Answer 1

You try change the order in @WebParam and @XmlElement? actually i have a WS whit this:

public Persona consultarPersona(@WebParam(name = "cedula") @XmlElement(required=true, nillable=false, name="cedula", namespace="cedulaParam")  String cedula) 

And the description generate is:

 <xsd:schema>
<xsd:import namespace="cedulaParam" schemaLocation="http://eniacstein-pc:8080/WSDL_Sample/GestorPersonas?xsd=2"/>
</xsd:schema>

and the schema definition:

    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" version="1.0" targetNamespace="cedulaParam">
<xs:element name="cedula" type="xs:string"/>
</xs:schema>

that's it!!

Answer 2

I have same problem. I found solution in using of separate class for parameters of service method.

e.g.

@XmlType(name="SampleRequestType", propOrder={"title", "ref"})
public class SampleRequest {
    @XmlElement(name="title", required=false)
    private String title;
    @XmlElement(name="ref", required=true)
    private String ref;
    ...

web-method

@WebMethod
public String sampleMethod(@WebParam(name = "params") SampleRequest params) {

maybe this will help

Perhaps I found the solution. If anyone encounters the same problem, just place these annotations in you web service contract(interface) in exact this order, as all guys answered before.

@WebParam(name = "yourParam") @XmlElement(required = true)  YourParam param

Answer 4

Adding @XmlElement(required=true,nillable=false) after @WebParam solved my similar problem. Using CXF 2.7.9. Did not try putting @XmlElement first, could it be that simple?

Answer 5

If you are having the following error message: "The annotation @XmlElement is disallowed for this location", chances are you're using the wrong import statement.

Change it to:

import javax.xml.bind.annotation.XmlElement;

As Eclipse suggests another package as the first option, it's a very common mistake.
