If only the server requires authentication you can take the outflow out. If the client needs to authenticate the response from the server you cannot.
As soon as I get a chance I'll get a test case together and submit a bug (unless one of you get in first) Until then maybe one of the Rampart devs would like to acknowledge the problem and maybe even fix it? ----- Original Message ---- From: Doug Haigh <[EMAIL PROTECTED]> To: "axis-user@ws.apache.org" <axis-user@ws.apache.org> Sent: Thursday, 22 May, 2008 3:41:29 PM Subject: RE: XMLStreamException "the prefix ==> Already exists for namespace" when WS-Security Rampart is engaged for Axis 2 web-services I am using Axis 2 1.3 with code generated using WSDL2JAVA with ADB binding. I am experiencing this same problem and I cannot take out my OutFlow security since the server requires user authentication and it cannot be disabled. Any suggested fixes to code?

Due to time constraints I couldn't look into it properly but tracked it down to the service response. We only require ws-security on the inbound from the service so I edited the modules.xml in rampart to remove the outbound security and this circumvents the problem. It may help short term and I'll be watching this thread to find out what the issue is.

**************************************************************************************************************************** I debugged the code and observed that, in the serialize method of the XML node POJO (generated by WSDL2JAVA), the "MTOMAwareXMLStreamWriter xmlWriter" parameter gets an instance of MTOMAwareOMBuilder if WS-Security is enabled. Whereas, without WS-Security it gets an instance of org.apache.axis2.databinding.utils.writer.MTOMAwareXMLSerializer which uses MTOMXMLStreamWriter which in turn uses com.ctc.wstx.sw.SimpleNsStreamWriter to serialize the response. I also tried using AXIS 1.4 without any success. Any idea how can this problem can be solved? Is there a way to let Rampart know which serializer should be used? Am I missing any configuration details of Rampart?
