java - Jersey REST error, MessageBodyWriter not found for media type=application/json -

-

I did not find the messaging recorder when I called for a web service call.

I have included genson-1.1.jar in my square path, which I believe is to include messaging implementation, I still get this error < P> I am using Jersey 2.13.

I have also tried without registering "GensonJsonConverter.class" and still gives the same error 

  protected zero doPost (HttpServletRequest request, HttpServletResponse resp) ServletException, IOException {ClientConfig config = new ClientConfig () throws; WebText target = client.target ("http: // localhost: 8080 / web services / comfort / hello"); Target.path ("Lion King"); Target.register (GensonJsonConverter.class); String response = target. request (). Accept (MediaType.APPLICATION_JSON) .get (String.class); Resp.getWriter () print (feedback). } @Path ("Hello") Public class greetings {@GET @Produces (MediaType.APPLICATION_JSON) public book getThisBook (@PathParam ("bookName") string bookName) {Return new book (bookName, "MSN", New Date) ); }}   
  web.xml   
    
 Part of stack trace:  
  Critical: MessageBodyWriter did not get to media type = application / json, type = class com.webservices.entity.book , Generic type = class com.webservices.entity.Book servlet.service () [myServlet] for reference with path [/ WebServices] in the context with reference javax.ws.rs.InternalServerErrorException threw: October 10, 2014 15:19 : 49 org.apache.catalina.core.StandardWrapperValve Great Call: HTTP 500 Internal Server Error

 1) Metanoff-Services Add Dependency to  
  OR   
 2) Register it programmatically.  
 
  
  Edit  As you do not create all such as  
 there is an explanation in more detail with advice. For the Container Program you will find it easy to use the Metannoff-Services solution.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
