java - JSP Servlet Multithreading Qustion -

-

I have a service which receives the request from the client, then the service has 5 different through HTTP request / feedback - Collected data from different servers (1 second required to answer each server) and sends data back to the customer.

The problem is that when the customer has to wait 6 seconds for the response then it is too long so 5 requests of 5 servers should be sent at the same time.

Thoughts:

  1. Multi-threading in servlets, such as in normal Java applications.
  2. One volunteerlet for each server (request), so that the Servlet 5 consisting of 1 main service number 5 "Receive data" and collect Servlets send data to the main servlet and main servlet back to the customer.

    I am scared about the problem, that a thread / servlet gets a response from another request because its same time and only one IP.

    How to solve this? Thanks!

    multithreading in servlet

    Which can put this request in asynchronous mode, and starts its AsyncContext with the original (inferred) ServletRequest and ServletResponse objects.

    It has been explained in detail, read more about it.

    asyncContext is a standard method defined to handle Servlet 3.0 specification HTTP request asynchronously < / P>

    Read more about this, that makes a thread pool that re-uses the thread of a fixed number of shared limitless operations off, at any time, most nThreads threads will have active processing functions. If all the threads are active, additional tasks are submitted, until there is no thread available, they will wait in queue.

    Please read more about this with sample code.

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ...

How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
