java - Handling many simultaneous AJAX requests with a struts2 action -

-

I've got a Struts 2 verb that responds to an AJAX request with some request parameters, a remote service call Data that XML gives, then changes the data via XSL and returning XHtml as a result of a stream result. The response is different depending on the given criteria.

There is an action class with a group of stuffs moved here: 

  public class ServiceHandler ActionSupport extended {Private ByteArrayInputStream inputStream; Public string executed () {string response = ""; // Receive request parameters // request for remote server via HTTP connection // Exxplore results via XSL / // uses dom4j for XML / XSL stuff // This should not be an empty response = ResultDoc.asXML (); Inputstream = new bytereinputstream (feedback .getBytes ()); Return "Success"; } Get public byteforeinestreams inputstream () {inputStream return; }}

And here are the important struts.xml bits:

My problem is that when I have multiple requests run at the same time, all service call the handler action, sometimes the reaction is completely empty (should never be) Sometimes the reaction is disconnected from some random number to beginning or end, and sometimes the responses change, so that an AJAX requestor receives a wrong response.

I know that this thread is a security issue, we have moved all the important variable definitions to the execute () method so that they are not an example variable (and therefore shared by everyone). The only interesting variable that is an instance variable is the inputstream, and I see it because of my problems.

Is there any way to make input strip variable yarn secure? Or is there another way I am not seeing?

I'm only familiar with Strush 1 but take a look in the Take Donolod action or just a plain strip Use the action, write the result directly on the reaction object and return the blank form to the next.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never
