synchronous

I have a MDB which listens to WebSphere MQ. It does not picks up the messages in the order that has been received by the Queue. How can i make it read it in that order? Is it possible? Should i not use a MDB. In general, WMQ delivers messages in the order that they were received. However, several things can impact that... If the queue is set to priority instead of FIFO delivery and messages arrive in different priorities, they will be delivered "out of order". Distinguish between order produced and order delivered. If the messages are produced on a remote QMgr and there are multiple paths to

While I understand that JavaScript is inherently single-threaded and generally frowns upon such things, I am wondering if there is any way to get a WebWorker to wait until some data is made available from the main thread without destroying the call stack of the WebWorker. As this is for a fun project, I can use new technologies and things that won't reliably run on older browsers, and I don't mind esoteric hacks as long as they work. Some other solutions that I have thought about: Continuously poll LocalStorage in a loop until there is data at a predetermined key. This would seem to work

I'm using a android-priority-jobqueue and I use retrofit to make synchronous calls to my rest api but i'm unsure how to handle errors like 401 Unauthorized errors which I send back json stating the error. Simple when doing async calls but I'm adapting my app for job manager. below is a simple try catch for IO exceptions, but 401's 422's etc? How to do this? try { PostService postService = ServiceGenerator.createService(PostService.class); final Call<Post> call = postService.addPost(post); Post newPost = call.execute().body(); // omitted code here } catch (IOException e) { // handle error }

Is there a way to receive multiple message using a single synchronous call ? When I know that there are N messages( N could be a small value less than 10) in the queue, then I should be able to do something like channel.basic_get(String queue, boolean autoAck , int numberofMsg ). I don't want to make multiple requests to the server . RabbitMQ's basic.get doesn't support multiple messages unfortunately as seen in the docs . The preferred method to retrieve multiple messages is to use basic.consume which will push the messages to the client avoiding multiple round trips. acks are asynchronous so

I'm trying to execute 3 'http requests'. The problem is, because of the nature of asynchronous mode, it doesn't execute in order. All requests are to internal apis. Here's the sample code :- setInterval(function () { // First request request({}, function (error, response, body) { // Second request request({}, function (error, response, body) { // Third request request({}, function (error, response, body) { }) }) }) },1000); What i'm trying to achieve is get data based on one condition ( First request ), update data ( Second request ) and send sms and emails ( Third request ). Because of the

I have a method in GWT which retrieves the DATA from the DB using the fire method of the requests as you all know its asynchronous I am calling this method from JS so I need to make synchronous is it possible private static String retriveLocation(String part) { ClientFactory clientFactory = GWT.create(ClientFactory.class); MyRequestFactory requestFactory = clientFactory.getRequestFactory(); YadgetRequest request = requestFactory.yadgetRequest(); String criteria = "!" + part; final ArrayList<String> tags = new ArrayList<String>(); request.getTagsStartingWith(criteria, 10, 0).fire( new Receiver

I have a pageTest.html in local folder,this page call a service.ashx?i=...(that return value param passed incremented +1) with follow Ajax code: . . getIncr: function(parameters, success){ $.ajax({ async: false, type: methodType, url: getTarget, data: "n="+parameters, dataType:"jsonp", success: success }); } . . The html page call this function for m time (with script..): . var start = function(){ . . var val = 0; . . for(i=0; i<m; i++) { Foo.getIncr(val, function(returned_n){ val = returned_n; }); } }; During the page loading, the calls are execute in "Asynchronous mode" but i setting " async
