I get the following exception when I execute the REST Client :
InboundJaxrsResponse{ClientResponse{method=GET, uri=http://localhost:8080/com.dcr.jersey.first/webapi/todo, status=406, reason=Not Acceptable}}
Exception in thread "main" javax.ws.rs.NotAcceptableException: HTTP 406 Not Acceptable
On web browser( when tomcat is running), the URL : http://localhost:8080/com.dcr.jersey.first/webapi/todo gives output
todo>
<description>This is my first todo - Description</description>
<summary>This is my first todo - Summary</summary>
</todo>
But running the client code throws the exception, what is the mapping that's missing here?, appreciate your guidance( included all code samples)
Here is the web.xml :

See Http Status Codes
406 Not Acceptable
The resource identified by the request is only capable of generating response entities which have content characteristics not acceptable according to the accept headers sent in the request.
The .accept(mediatype)
is what set the Accept
header for the request. You currently have five requests, each accepting a different type
MediaType.TEXT_PLAIN
,MediaType.TEXT_HTML
,MediaType.TEXT_XML
,MediaType.TEXT_PLAIN
,MediaType.APPLICATION_JSON
This is Content-Negotiation at work. The server side configuration of this is with the use of the @Produces
(which goes in hand with the Accept
header) and @Consumes
(which goes in hand with the Content-Type
header).
That being said, look at all your @Produces
annotations. You currently only support the producing of media types
MediaType.APPLICATION_XML
,MediaType.TEXT_XML
,MediaType.APPLICATION_JSON
The missing ones are in bold above. Remove those, and given all else is correct, this should work for you.
Check your content type!
Setting to .accept(MediaType.TEXT_PLAIN)
worked for me.
