Exception : getWriter() has already been called for this response
Hi,
I have implemented RESTful CXF service with my spring project. in impl
class, I have used MessageContext to retrieve HttpResponse and I am using
response.getWriter() to set HttpResponse with my content.
when I call this service from browser, I get the response what I have set in
impl, but on tomcat console, I am getting following exception. Please help.
this is the last piece of work I have left to finish my task.

Hi Sergey,
I am facing another problem while calling my REST service. I have already
sent my impl class code earlier in this mail thread. It seems that my partly
impl code executes 2 times. following is my tomcat log. Please look into the
log marked bold. any idea please?

Thank you Sergey,
another option also worked perfectly. only difference between the 2
options
are :
with my approach(using HttpResponse), browser shows complete XML file
(with
nodes also). where as by using Response object as you mentioned below,
it
only shows content(values) of XML file I am feeding. but both the
options
sent entire XML file in response body perfectly if you check response
content in browser using a tool like firebug.
Thanks again.

RE: Exception : getWriter() has already been called for this response
Posted by Sergey Beryozkin <sb...@progress.com>.
Hi
This is one possible option, another one is to return a Response :
return Response.status(200).entity(theInputStream).build()

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?

Parimal

Not necessarily - you can return an input stream pointing to your xml file.
If you return a jaxrs Response from your method then you can also set the required content type to be associated with a given input
stream..
Also, I'm not sure about the other question you posted in the follow-up message. Apparently you;re using a deprected CXF HTTP
binding - I can not help there, I was not even involved in that project. Please consider using either JAXWS support for doing HTTP
services or migrate to JAXRS

Re: Exception : getWriter() has already been called for this response
Posted by Parimal Dhinoja <pd...@gmail.com>.
Thank you so much Sergey for prompt reply and the links.
I agree that JAX-RS might be more appropriate solution to my problem.
But I still has a query about Response object. As you see, I need to read
the phisical XML files that are stored on file system and based on user
query parameter, I need to read one of those files and feed into Response
stream.
As per my understanding, jax-rs return xml response of the pojo class you
have defined.
so Please let me know, what I have implemented to return my physical xml
file, is correct and whether it will work. I have to get HttpResponse from
MessageContext and feed my xml file into response's body.
As I said, I am new to CXF and may be there are better solutions to the
problem I have which I am not aware of. It would be great if you suggest
specific to my problem on hand.
Again, I really appreciate you help.
Regards,
Parimal

this is a JAXWS code but you can do REST with it if you'd like to. You'd probably want to use Provider<Source> though, see
http://svn.apache.org/repos/asf/cxf/trunk/distribution/src/main/release/samples/restful_dispatch/
alternatively, please consider using JAXRS

Thank you Sergey,
Yes it seems working. now I haven't got any exception. but I am not
verifying it. Actually following is my code in impl. I am sending xml file

or overwrite by further interceptor process. I am using this service from
browser. Please let me know what I am doing is right way of doing it. I am
beginner to CXF REST.

Hi
Please try writing to response.getOutputStream() and it should work. I
missed overriding
response.getWriter() in the HttpResponse context implementation.
let me know please if it works
