Hi Sergey, I was going through this thread since I want to enable GZIP on
encoding server side.I have successfully configured GZIP encoding by adding
cxf:feature in cxf's xml. I have also added @GZIP annotation to the resource
file. Below is the set of annotations over resource file:@GZIP@Produces({
MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })@Consumes({
MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML,
MediaType.APPLICATION_FORM_URLENCODED })I have a few doubts. Hope you can
help me understand them. I am using fiddler to send the request.1. When I am
sending request with below header:> If it sends: > Accept-Encoding:
gzip,deflate > Accept: */* Response generated is in JSON format but it is
GZIP encoded. In this case Content-Encoding is not set to GZIP.2. When I am
sending request with below header:Accept-Encoding: gzip,deflate Accept:
application/xmlResponse generated is in XML format and its GZIP encoded. In
this case Content-Encoding is set to GZIP.Does GZIP encoding is not
supported in case response returned is in JSON format??Thanks for any
pointers.PG.
