java - Use of WorkManagr API in J2EE application is viable? -

-

J2EEE specification says that it is not appropriate to create or create user-defined thread in application logic. As a reason, I think the resource dispute is to avoid issues of sync and memory leaks.

But it also suggests using the ManagedExecutorService or the WorkManager API implementation, both of these implementations also have threads produced under the thread.

How is it appropriate to use these APIs and not use threads? First, the Workmanager API is available only for this, so in this way I will address mostly Managed Exposure Service, But whatever I say applies to the work manager too.

The difference between using the Managed Accelerator Service / Workmanager and creating your own thread is that the application manages the built-in threads. This means that the threads you used with this API, and generally javax.enterprise.concurrent * Through the classes, whether in the case of asynchronous work, or explicitly with one, the application provided by the application provides a fixed stability, specific transaction management, security, resource management etc. .

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...
