JAXB :Need Namespace Prefix to all the elements

Question

I am Using Spring WebServiceTemplate to make webservice call which uses JAXB to generate request XML. My requirement needs all the elements (including root) to have a namespace prefix (there is only a single namespace) in the SOAP request.

Ex :

<ns1:Login xmlns:ns1="www.example.com/a">     <ns1:username>abc</ns1:username>     <ns1:password>abc</ns1:password> </ns1:Login> 

But i am getting

<Login xmlns="www.example.com/a">     <username>abc<username>     <password>abc<password> </Login> 

xsd :

<?xml version="1.0" encoding="UTF-8"?> <xs:schema targetNamespace="www.example.com/a"   xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ilreq="www.example.com/a" elementFormDefault="qualified" attributeFormDefault="unqualified">  <xs:complexType name="Login">     <xs:sequence>         <xs:element name="username" type="xs:string"/>         <xs:element name="password" type="xs:string"/>     </xs:sequence> </xs:complexType> 

Generated Java Class from XSD

@XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "Login", propOrder = {     "username",     "password" })  @XmlRootElement public class Login {  @XmlElement(required = true) protected String username; @XmlElement(required = true) protected String password; ...... } 

package-info.java

@javax.xml.bind.annotation.XmlSchema(     namespace = "www.example.com/a",     elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED) package authenticator.beans.login; 

Want to know how to generate the request XML with Namespace prefix to all elements including root.

Answer 1

Solved by adding

@XmlSchema(     namespace = "http://www.example.com/a",     elementFormDefault = XmlNsForm.QUALIFIED,     xmlns = {         @XmlNs(prefix="ns1", namespaceURI="http://www.example.com/a")     } )    package authenticator.beans.login; import javax.xml.bind.annotation.*; 

in package-info.java

MSK,

Have you tried setting a namespace declaration to your member variables like this? :

@XmlElement(required = true, namespace = "http://example.com/a") protected String username;  @XmlElement(required = true, namespace = "http://example.com/a") protected String password; 

For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.
