Juanda Zeng commented on AXIS2-428:
-----------------------------------

I believe it's best to avoid using System.setProperty(...) for this case 
because other threads may be forced to use DOOM's DocumentBuilder when the 
security handlers are running.

> UnsupportedOperationException("TODO") when unimplemented methods of 
> org.apache.axis2.om.impl.dom.jaxp.DocumentBuilderImpl class are called.

>          Key: AXIS2-428
>          URL: http://issues.apache.org/jira/browse/AXIS2-428
>      Project: Apache Axis 2.0 (Axis2)
>         Type: Bug
>   Components: om
>     Versions: 0.94
>  Environment: Windows XP Pro, JBoss 3.2.3
>     Reporter: Juanda Zeng

>
> Since development of the classes in the org.apache.axis2.om.impl.dom.jaxp 
> package is still in progress, quite a few methods in the DocumentBuilderImpl 
> class are still not implemented yet.
> These methods throw UnsupportedOperationException("TODO") when called.
> Currently, WSDoAllReceiver and WSDoAllSender make system-wide change by 
> setting the "javax.xml.parsers.DocumentBuilderFactory" property to 
> org.apache.axis2.om.impl.dom.jaxp.DocumentBuilderFactoryImpl.
> This causes client modules to fail should there be a call to one of the 
> unimplemented methods.
> It is best to avoid using its DocumentBuilder until it is ready for testing.
> SUGGESTED TEMPORARY WORKAROUND:
> ----------------------------------------------------------------
> Use the DocumentBuilder from JDK (Crimson). Modify the newDocumentBuilder() 
> method of the org.apache.axis2.om.impl.dom.jaxp.DocumentBuilderFactoryImpl 
> class as follows:
>   public DocumentBuilder newDocumentBuilder()
>           throws ParserConfigurationException {
>       /**

>        * Since development is still in progress and a few methods are still 
> not implemented yet,
>        * it is best to avoid using its DocumentBuilder until it is ready for 
> testing.
>        * We will use the one from JDK (Crimson).
>        */
>       // return new DocumentBuilderImpl();
>       return new 
> org.apache.crimson.jaxp.DocumentBuilderFactoryImpl().newDocumentBuilder();
>   }
