XJB and JAXB binding on simpleType with same name

Question

I'm trying to generate JAVA code with jaxb and spring but I can't get it to work when I have as wsdl file with 2 simpleTypes with the same name but in different namespaces. Does anyone know how I can solve this?

I've been trying out the jaxb:factoryMethod tag but I can't get the syntax correct. But maybe there is a simpler way?

binding.xjb

We have solved this now and it was the <generatePackage> element that was causing part of the problem. We also made sure to bind each schema/namespace to its own package. This way the ObjectFactory Classes won't complain.

pom.xml

<plugin>
    <groupId>org.jvnet.jaxb2.maven2</groupId>
    <artifactId>maven-jaxb2-plugin</artifactId>
    <version>0.12.3</version>

          <goal>generate</goal>
        </goals>
        <configuration>

          <!-- see binding.xjb

          <extension>true</extension>
          <forceRegenerate>true</forceRegenerate>
          <bindingIncludes>

binding.xjb

  <jaxb:bindings schemaLocation="../../../target/classes/disb.wsdl"
     node="/wsdl:definitions/wsdl:types/xs:schema[@targetNamespace='http://com.company/generated/storetax']" >
     <jaxb:schemaBindings>
         <jaxb:package name="com.company.generated.storetax"></jaxb:package>
     </jaxb:schemaBindings>
</jaxb:bindings>

<jaxb:bindings schemaLocation="../../../target/classes/disb.wsdl"
    node="/wsdl:definitions/wsdl:types/xs:schema[@targetNamespace='http://com.company/storeaccount']" >
    <jaxb:schemaBindings>
        <jaxb:package name="com.company.generated.storeaccount"></jaxb:package>
    </jaxb:schemaBindings>
</jaxb:bindings>

No, @XmlRootElement won't help. It's about method names in ObjectFactory.

Are you sure it's simple types which cause a collision? XJC is pointing out to methods in the ObjectFactory, so it should be global elments, not simple types

Here's an example of the factoryMethod customization:

<jaxb:bindings 
    schemaLocation="http://schemas.opengis.net/citygml/texturedsurface/1.0/texturedSurface.xsd" 
    node="/xs:schema">
    <jaxb:bindings node="xs:element[@name='_Appearance']">
        <jaxb:factoryMethod name="AAppearance"/>
    </jaxb:bindings>
</jaxb:bindings>

You'll need to find out which elements cause a collision and customize them. Not the simple types.
