-----------------------------------

Hi John,
As you said I have fixed the problems with patch files and modified codes according to JIRA (WODEN-177). Also I have removed the woden.internal.DOMUtils class. But I didn't touch rest of the code because still I'm having basic questions to solve. Here I have listed below.

(2) parseXXX () methods of WSDLWriter take XMLElement as a parameter. In my case I use Woden Elements as parameters for   printXXX() methods. I'm interesting to have some comments on this issue also. I think this issue is relevant to the point you mentioned in your last mail.
 
> Note that DOM elements (and OMElement) 
> are represented in Woden by XMLElement and many of the element access 
> method available via DOMUtils are now available via the XMLElement 
> interface. We might need to think about how to access and use XMLElement 
> objects to serialize the WSDL.
 
It is much easy to me go forward, If you can provide a descriptive comments for above issues .
thanks

> When we load a WSDL in to Woden object model, there is no way to serialize the object model in to an output stream. This is very much useful when some one wants to make sure Woden can properly spit out what it has read. 
> And there is a requirement from Axis2 also to make Woden element serializable to cater for ?wsdl2 requests.
