how to get form filled data in Jbpm 5.4 -

-

I am creating an application using Jbpm 5.4. Every user has a work form in the job and I participated in them through the comfort API. All work is going on well and the statistics table, but I want to know how the JBMP API gets data that fills the user in previous states? Does the data feed those data associated with the table? Can anyone tell me how do I get my own data? I tried the following. 

  Try {Blocked Gate Content ResponseResparsharsHandler = New BlockingGet Content Response Handler (); Client.getContent (contentId, responseHandler); Content Content = ResponseHandler.Gate Content (); Byte [] byteContent = content.getContent (); Bytereinputstream bytereinputstream = new bytereinputstream (byte content); ObjectInputStream inputstream = new object inputstream (bytereinputstream); Obj = inputStream.readObject (); } Catch (Throwable T) {T. Preststacktress (); }    
 
 
 This code is used to get jbpm-console work data :

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...
