मेरे पास एक विधि है 

  सार्वजनिक प्रतिक्रिया xyz (JAXBElement & lt; T & gt; अनुरोध) {। .....}   
 दो अलग-अलग जगहों को इसे अलग जेएक्सबीएलेमेंट के साथ बुलाया जा रहा है।  xyz (JAXBElement & lt; a & gt;)  और  xyz (JAXBElement & lt; B & gt;) के साथ अन्य   
 मैं अपनी विधि का सेवन सामान्य कैसे बना सकता हूं ताकि यह दोनों विधियों के साथ काम करता है?   
 
 
 कृपया प्रयास करें:  
  xyz (JAXBElement & lt;? & Gt; माई एलेमेंट);   
 कृपया जेनेटिक्स पर यह देखें:  
 
 तो सभी प्रकार के संग्रहों का सुपरटेप क्या है? यह  संग्रह & lt;? & Gt;  (उजागर "अज्ञात का संग्रह") लिखा है, अर्थात, एक संग्रह जिसका तत्व प्रकार से मेल खाता है। इसे स्पष्ट कारणों के लिए एक वाइल्डकार्ड प्रकार कहा जाता है हम लिख सकते हैं:  
  void printCollection (संग्रह & lt;? & Gt; c) {for (ऑब्जेक्ट ई: c) {System.out.println (e); }}   
 और अब, हम इसे किसी भी प्रकार के संग्रह से कॉल कर सकते हैं।

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...

"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...
