Hi Rohan,
You found a bug in the simple servlet sample, which i have fixed. The
general GET method, "doGet", was not setting the media type.
I changed the switch statement to:
switch (rep) {
case 0:
r = Response.ok(help, "text/plain").
header("resource3-header", "text/
plain").build();
break;
case 1:
r = Response.ok(getStringRep(arg1, arg2), "text/
plain").
header("resource3-header", "text/
plain").build();
break;
case 2:
r = Response.ok(getFormURLEncodedRep(arg1, arg2),
"application/x-www-form-urlencoded").
header("resource3-header", "application/x-www-
form-urlencoded").build();
break;
case 3:
r = Response.ok(getImageRep(), "image/jpg").
header("resource3-header", "image/
jpg").build();
break;
default :
r = Response.ok(help, "text/plain").build();
break;
}
Essentially with this method it overrides what may be the msot
acceptable in the accept header based on the quest parameter "rep".
What you require is supported, it is just that the browser is going to
the general GET method because the @Consumes is "*/*" by default in
the absence of the annotation, and because the accept header of the
browser has a higher preference for anything other than "text/plain",
"application/x-www-form-urlencoded" or "image/jpg".
If you do a curl, say:
curl -v -H "Accept: image/jpg"
http://localhost:8080/SimpleServlet/resources/resource3/fred/barney
then this will go to the "getImageRep" method and the content type
will be set to "image/jpg".
