[jira] Commented: (AXIS-2436) using call.invoke() from client java program to invoke web service inserts empty namespace on all elements in message sent

["George Cowe (JIRA)" <ax...@ws.apache.org>]

    [ http://issues.apache.org/jira/browse/AXIS-2436?page=comments#action_12371200 ] 

George Cowe commented on AXIS-2436:
-----------------------------------

I have found a workaround to this problem -
The problem is caused by the test client's SOAPBodyElement constructor which takes a org.w3c.dom.Document as an argument. There seems to be a bug with this Axis class constructor.
If I switch to using the SOAPBodyElement with an InputStream as a constructor the problem goes away.

> I am attempting to use the message-style processing in a web service implemented in Axis 1.3. The client java program creates a SOAPBodyElement from my XML and uses call.invoke() to send it to the service. 
> Using XMLUtils.DocumentToString() I can see that the org.w3c.Document has been created successfully from the XML.
> However the error message returned states : 
> org.xml.sax.SAXParseException: The value of the attribute "prefix="xmlns",localpart="ce",rawname="xmlns:ce"" is invalid. Prefixed namespace bindings may not be empty.   
> Using a TCP/IP monitor I can see that Axis has inserted a blank namespace on all elements:  xmlns:ce="".
> The XML used to create the org.w3c.Document validates against my schema (which has a targetNameSpace defined as well as the xmlns:ce namespace).
> So I do not understand why the empty namespaces are being added to the document.
