Solve JAXB "name collision in the ObjectFactory class" problem with customisation

Question

Executing a "xjc" command on these xsd files returns a Two declarations cause a collision in the ObjectFactory class because there are 2 elements named "Scale" and "scale".

According to this page, this problem may be solved by customizing the xsd files with <factoryMethod>.

Do you know how to do that? Do you have an example of binding file to do that?

Answer 1

You can use the bindings tag. Set the schemaLocation attribute to the location of a particular xsd. The child tags, schemaBindings and package, then define a new package namespace for that xsd. Below is the bindings file I used with xjc a while ago. If it still works, great. If not, example =).

<?xml version="1.0" ?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb" version="2.1"
      xmlns:kml="http://www.opengis.net/kml/2.2"
      xmlns:atom="http://www.w3.org/2005/Atom">

  <bindings schemaLocation="ogckml22.xsd">
    <schemaBindings>
      <package name="net.opengis.kml"/>
    </schemaBindings>
  </bindings>
  <bindings schemaLocation="kml22gx.xsd">
    <schemaBindings>
      <package name="net.opengis.kml.ex"/>
    </schemaBindings>
  </bindings>
  <bindings schemaLocation="atom-author-link.xsd">
    <schemaBindings>
      <package name="org.w3c.atom"/>
    </schemaBindings>
  </bindings>
  <bindings schemaLocation="xAL.xsd">
    <schemaBindings>
      <package name="org.oasis.xal"/>
    </schemaBindings>
  </bindings>
  <bindings scd="kml:scale">
    <class name="scaleliteral"/>
  </bindings>
  <bindings scd="kml:snippet">
    <class name="snippetliteral"/>
  </bindings>
  <bindings scd="kml:Snippet">
    <property name="snippetDeprecated"/>
  </bindings>
  <bindings scd="atom:link">
    <property name="atomLink"/>
  </bindings>
</bindings>
