Hi This is one possible option, another one is to return a Response :
return Response.status(200).entity(theInputStream).build() cheers, Sergey -----Original Message----- From: Parimal Dhinoja [mailto:pdhin...@gmail.com] Sent: 18 November 2009 19:46 To: users@cxf.apache.org Subject: Re: Exception : getWriter() has already been called for this response Thanks Sergey, I have given a try with JAX-RS and I am able to return my XML file. I have created a resource class where I defined a method. This method get HttpResponse object from MessageContext, read XML file from file system and then feeding it to HttpResponse outputstream. Please let me know if it is ok. Also How can I use JAX-RS response object to accomplish the same task?
