JAXB :Need Namespace Prefix to all the elements

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.

Was facing this issue, Solved by adding package-info in my package

and the following code in it:

@XmlSchema(
    namespace = "http://www.w3schools.com/xml/",
    elementFormDefault = XmlNsForm.QUALIFIED,
    xmlns = {
        @XmlNs(prefix="", namespaceURI="http://www.w3schools.com/xml/")
    }
)  
package com.gateway.ws.outbound.bean;

import javax.xml.bind.annotation.XmlNs;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

To specify more than one namespace to provide prefixes, use something like:

@javax.xml.bind.annotation.XmlSchema(
    namespace = "urn:oecd:ties:cbc:v1", 
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
    xmlns ={@XmlNs(prefix="cbc", namespaceURI="urn:oecd:ties:cbc:v1"), 
            @XmlNs(prefix="iso", namespaceURI="urn:oecd:ties:isocbctypes:v1"),
            @XmlNs(prefix="stf", namespaceURI="urn:oecd:ties:stf:v4")})

... in package-info.java
