>          Components: Deployment - Axis2

>         Environment: WLS 9.2
>            Reporter: James Shiell

> When WLS 9.2 is used and the BEA StAX parser (as opposed to Woodstox) is being used the AxisEnvironment class fails in the convertToDOM(OMElement) method. This appears to be due to a WLS bug, where the serialised XML ommits namespace declarations.
> Given that it is not always possible to structure the classpath to use Woodstox I have included a potential fix that does not rely on serialisation, instead converting objects directly. This is compatible with both implementations and hopefully slightly faster as well.
> AxisEnvironment.java:
>     /**
>      * Convert Axiom to DOM. Muse uses the DOM API in the JDK, Axis2 uses
>      * the Axiom API, which is similar but... different.
>      *
>      * @param axiom the OM element.
>      * @return the converted element.
>      */

>             final Document doc = domBuilder.newDocument();
>             return convertToDom(axiom, doc);
>         }
