  • Java Can't Find File when Running through Eclipse

    - by derekerdmann
    When I run a Java application that should be reading from a file in Eclipse, I get a java.io.FileNotFoundException, even though the file is in the correct directory. I can compile and run the application from the command line just fine; the problem only occurs in Eclipse, with more than one project and application. Is there a setting I need to change in the run configurations or build paths to get it to find the file correctly?

  • jQuery addClass() not running before jQuery.ajax()

    - by Josh
    I'm trying to have a button that onclick will apply a class loading (sets cursor to "wait") to the body, before making a series of ajax requests. Code is: $('#addSelected').click(function(){ $('body').addClass('loading'); var products = $(':checkbox[id^=add_]:checked'); products.each(function(){ var prodID = $(this).attr('id').replace('add_', ''); var qty = $('#qty_' + prodID).val(); if($('#prep_' + prodID).val()) { prodID += ':' + $('#prep_' + prodID).val(); } // Have to use .ajax rather than .get so we can use async:false, otherwise // product adds happen in parallel, causing data to be lost. $.ajax({ url: '<?=base_url()?>basket/update/' + prodID + '/' + qty, async: false, beforeSend: function(){ $('body').addClass('loading'); } }); }); }); I've tried doing $('body').addClass('loading'); both before the requests, and as a beforeSend callback, but there is no difference. In firebug I can see that body doesn't get the loading class until after the requests are complete. Any ideas?

  • Running server-program from a .jar file

    - by skiwi
    I have created and am working on a server-application that monitors for specific folders and takes appropriate actions whenever files are being added. Now I come to the point where I want to be able to shutdown the program, for example for applying a patch. The server runs simply in a command prompt, how can I signal that I want to perform maintenance on it? I do not think reading System.In is feasible as I am also outputting text in the prompt. Regards.

  • Python beginer having trouble running code

    - by Protean
    For some reason this code will not seem to run in the interpreter. When I hit F5 nothing happens, not even the debugger seems to recognize it. I assume it has something to do with the class, as when removed the interpreter seems to recognize the rest of the code. Please tell me what I am doing wrong. Edit: I have restarted the interpreter multiple times, any other piece of code I try to load runs fine, just this one is having trouble. print ('Why won't this work?') class sorting_class: def __init__(self): self.order = ['a', 'b', 'c', 'd'] self.globali = 0 self.orderi = 0 self.sortedlist = [] def sort(self, array): carry, leave = [] for arrayi in array: print ('run', arrayi) if self.order[self.orderi] == arrayi[self.globali]: carry.append(arrayi) else: if self.globali != 0: leave.append(arrayi) return carry, leave def srt(self, array): globalii = 0 carry, leave = my.sort(array) while len(self.sortedlist) != len(array): if len(self.carry) == 1: self.sortedlist.append(carry) arrayt = leave self.globali = 1 self.orderi = 0 carry, leave = my.sort(arrayt) elif len(self.carry) == 0: if len(self.leave) != 0: arrayt = leave self.globali = 1 self.orderi += 1 my.sort(arrayt) else: self.arrayt globalii += 1 self.orderi = globalii self.globali = 0 my.sort(arrayt) self.orderi = 0 else: arrayt = carry carry = [] self.globali += 1 carry, leave += my.sort(arrayt) my = sorting_class() x = ['ac', 'bc' ,'ab', 'da'] my.srt(x)

  • What to do when ServerSocket throws IOException and keeping server running

    - by s5804
    Basically I want to create a rock solid server. while (keepRunning.get()) { try { Socket clientSocket = serverSocket.accept(); ... spawn a new thread to handle the client ... } catch (IOException e) { e.printStackTrace(); // NOW WHAT? } } In the IOException block, what to do? Is the Server socket at fault so it need to be recreated? For example wait a few seconds and then serverSocket = ServerSocketFactory.getDefault().createServerSocket(MY_PORT); However if the server socket is still OK, then it is a pity to close it and kill all previously accepted connections that are still communicating. EDIT: After some answers, here my attempt to deal with the IOException. Would the implementation be guaranteeing keeping the server up and only re-create server socket when only necessary? while (keepRunning.get()) { try { Socket clientSocket = serverSocket.accept(); ... spawn a new thread to handle the client ... bindExceptionCounter = 0; } catch (IOException e) { e.printStackTrace(); recreateServerSocket(); } } private void recreateServerSocket() { while (keepRunning) { try { logger.info("Try to re-create Server Socket"); ServerSocket socket = ServerSocketFactory.getDefault().createServerSocket(RateTableServer.RATE_EVENT_SERVER_PORT); // No exception thrown, then use the new socket. serverSocket = socket; break; } catch (BindException e) { logger.info("BindException indicates that the server socket is still good.", e); bindExceptionCounter++; if (bindExceptionCounter < 5) { break; } } catch (IOException e) { logger.warn("Problem to re-create Server Socket", e); e.printStackTrace(); try { Thread.sleep(30000); } catch (InterruptedException ie) { logger.warn(ie); } } } }

  • Running shell scripts with sudo through my web app

    - by nfm
    I have some functionality that interfaces with the server's OS in my web application. I've written a bash script and am able to run it from within my app. However, some functionality of the script requires superuser privileges. What is the most sane way to run this script securely? It is being passed arguments from a web form, but should only be able to be called by authenticated users that I trust not to haxxor it.

  • .NET Remoting Client's Problem when running on the machine with Multi NICs

    - by cui chun
    I built a .NET Remoting Client which works quite fine on the machine of single NIC, and lots of testing messages received via remoting event. But when additional NIC was added, the Client seemed to be able to connect the remoting Server, but the testing messages cannot arrive anymore. From debugging, the server end did trigger the event but the client didn't get that. Checking from google and find that a similar problem report: http://www.eggheadcafe.com/community/aspnet/2/10061570/reply.aspx I just wonder if any solutions? Thanks in advance!

  • java applet stops running on exceptions

    - by Marius
    I've developed a simple applet that imports an image from the clipboard. When i run the class file from NetBeans, everything works fine. But when i try to run it as an applet ... it gives me lots of errors in the java console and does not run ... - The applet is signed - There is a static method in one class, called getImageFromClipboard(). When the applet runs, it calls this method. - getImageFromClipboard() method has a try-catch block and suppresses all errors. It simply returns either a BufferedImage or null. - When applet runs, it does some visual adjustments before calling getImageFromClipboard() Now the scenario is as follows: the class from netbeans runs, fails to import the image and adjusts the interface accordingly (displays an error in a label) But when i run it in a browser, java console is filled with errors and nothing after the getImageFromClipboard() line works. Although the applet itself loads and does everything it's supposed do do before importing the image. So why am i getting errors if i accept the certificate and all of the possible errors are in try-catch blocks? None of this code should throw any exceptions. Any ideas why this is happening? Or do you need to see the errors to tell? UPDATE I've managed to find out the problem myself. The class that i'm using is not in the jar file :( How do i add it in? I'm using "add jar folder" in netbeans on the libraries package to import it but it does not seem to get copied to the jar.

  • Failing to send key presses to a running process in C#

    - by Waffles
    I'm using the following code to put the focus on a window (in this case, a notepad window), and sending some key presses to it everytime button 2 is clicked. However, when I press button 2, nothing happens. Can anyone tell my why my sendkeys command is failing? public partial class Form1 : Form { [DllImport("user32.dll")] static extern bool ShowWindow(IntPtr hWnd, int nCmdShow); private Process s; public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { this.s = new Process(); s.StartInfo.FileName = "notepad"; s.Start(); s.WaitForInputIdle(); } private void button2_Click(object sender, EventArgs e) { ShowWindow(s.MainWindowHandle, 1); SendKeys.SendWait("Hello"); } }

  • Running resize2fs on /

    - by Paul Steckler
    I'm trying to resize an ext4 filesystem on a Fedora 11 box. Using fsdisk and lvm, I was able to grow the partition and logical volume containing the filesystem. When I try to run resize2fs on the device containing the filesystem (/dev/sda2 in this case), I get: "Device or resource busy while trying to open /dev/sda2, Couldn't find valid filesystem superblock" I've tried this from a rescue disk that doesn't have the filesystem mounted, no joy. Maybe resize2fs doesn't know about ext4?

  • Running Multiple Google App Engine Apps from one Domain

    - by awegawef
    I would like to have the following: myrootsite.appspot.com myrootsite.appspot.com/app1 myrootsite.appspot.com/app2 etc. Is this possible? I know I could just make /app1 be handled by app1, but then the redirects and everything wouldn't work unless I explicitly used redirect('/app1') instead of the current redirect('/'). Is there a way I can just upload my current apps (app1, app2, etc.) to the root site and have them work regularly? Thanks in advance

  • How to get the running of time of my program with gettimeofday()

    - by Mechko
    So I get the time at the beginning of the code, run it, and then get the time. struct timeval begin, end; gettimeofday(&begin, NULL); //code to time gettimeofday(&end, NULL); //get the total number of ms that the code took: unsigned int t = end.tv_usec - begin.tv_usec; Now I want to print it out in the form "**code took 0.007 seconds to run" or something similar. So two problems: 1) t seems to contain a value of the order 6000, and I KNOW the code didn't take 6 seconds to run. 2) How can I convert t to a double, given that it's an unsigned int? Or is there an easier way to print the output the way I wanted to?

  • Running non-existing jar does not cause any expection/error

    - by Nikolay Kuznetsov
    Please, consider the following snippet which is being run from Eclipse. Even though the external jar file does not exist no Exception is thrown and process is not null. Why is it so? try { Process process = Runtime.getRuntime().exec("java -jar NonExisting.jar"); if (process == null) System.out.println("process = null"); else System.out.println(process); } catch (IOException e) { System.err.println(e); } It prints java.lang.ProcessImpl@1a4d139 If I run it manully from command line then there is an error: C:\Users\workspace\Project\src>java -jar NonExisting.jar Error: Unable to access jarfile NonExisting.jar

  • load-views when running multiple noir servers

    - by Roth Michaels
    I'm experimenting with using noir to start three servers (each to handle a different aspect of the application). I am trying to do this so that I can run all three servers within one application while developing and easily decouple the project into three different applications for deployment. It is no problem to use noir.server/start and noir.server/stop to run the jetty servers I need. What I'm trying to figure out is some way to call load-views (or something like that) with a different set views for each server so that URI conflicts are handled by the correct defpage.

  • Running Send_SMS method from BroadcastReceiver

    - by burmat
    My application is an auto-reply application for text messages. I have a BroadcastReceiver for when a message arrives, and I need it to run a public method (Send_SMS). SMS_Sender.sendSMS(phoneNumber, messageText); does not work however, and eclipse wants to change my method to static. This would not be an issue if I did not have more receivers that catch when the message is sent/delivered/etc in this class. These receivers are then errors for being contained in a static method. So my question is, how do I run this method from a broadcast receiver so I can send the auto reply whenever it is triggered with a received message? -Thank you in advance, Nate

  • OpenMP - running things in parallel and some in sequence within them

    - by Sayan Ghosh
    Hi, I have a scenario like: for (i = 0; i < n; i++) { for (j = 0; j < m; j++) { for (k = 0; k < x; k++) { val = 2*i + j + 4*k if (val != 0) { for(t = 0; t < l; t++) { someFunction((i + t) + someFunction(j + t) + k*t) } } } } } Considering this is block A, Now I have two more similar blocks in my code. I want to put them in parallel, so I used OpenMP pragmas. However I am not able to parallelize it, because I am a tad confused that which variables would be shared and private in this case. If the function call in the inner loop was an operation like sum += x, then I could have added a reduction clause. In general, how would one approach parallelizing a code using OpenMP, when we there is a nested for loop, and then another inner for loop doing the main operation. I tried declaring a parallel region, and then simply putting pragma fors before the blocks, but definitely I am missing a point there! Thanks, Sayan

  • JFrame the same shape as an Image / Program running in background

    - by Jan Weber
    My question is simple, the solution surely not. I am looking for a way to shape a JFrame the same as an Image it will be displaying. By shape I mean the shape of the pixels that have an alpha != 0. I've already found a working example using a GeneralPath object, but it created ~110000 "nodes" for an Image of about 500*400, so starting the JFrame took more than 2 minutes, which is definitely not the desired effect, the startup should be in under 2 seconds. Thanks for your time.

  • My object becomes NSCFArray when running on iPhone

    - by cagreen
    I'm really scratching my head on this one: I have an object (MyObject) which I instantiate, and this object has an NSArray member variable. The following simple code working in the sim: MyObject *myObj = [[MyObject alloc] init]; NSArray *arr = [myObj myMemberArray]; When I hover over myObj in XCode the tooltip reads "MyObject". Good! But when I debug it on the device (OS 3.1.3) I get: "[NSCFArray myMemberArray]: unrecognized selector sent to instance ... " When I hover over myObj, sure enough it reads "NSCFArray". Can anyone give me some pointers on where to go next with this? Thanks.

  • Windows 7 running as server

    - by Artur
    I'm developing a program using Windows 7. There are WCF services (soap, rest) that are used by currently by Silverlight but very soon I'll start development of the mobile application that would make use of these services. On day to day basis I use Mac and Apache to host my website, but during the development of this program I would like to use IIS7 to put my services online. I have absolutely no problems to access all the services via localhost but as soon as I'm trying to connect through the internet I get "The connection has timed out". I'm sure that my router is configured right as it works perfectly fine when I'm on Mac OS, but it looks like Windows simply blocks incoming connections from outside; I cannot even connect from another computer on the same network. So is there a way of using Windows 7 as server with IIS7 or is it only possible with Windows Server? I know it might be like enabling/disabling one setting somewhere but I just cannot find it. Please help.

  • Running a program in another one?

    - by Roman
    Hi, I've written a program in C++. It's just using the console to have it as portable as possible. Unfortunately, many Windows-Users seem not to understand how to use the program (Linux Users are just fine with it :) ). So I'd like to write a GUI for that program. As this needs to run on Windows only, I'd like to write it in C#. But I want to maintain the GUI apart from the original program. So basically, I need a way to include a compiled *.exe into another program. Is there a way to catch the console output from another program and send inputs to it? Also, can the console of the original program be hidden? Similar Questions How To: Execute command line in C#, get STD OUT results

  • Access violation when running native C++ application that uses a /clr built DLL

    - by doobop
    I'm reorganzing a legacy mixed (managed and unmanaged DLLs) application so that the main application segment is unmanaged MFC and that will call a C++ DLL compiled with /clr flag that will bridge the communication between the managed (C# DLLs) and unmanaged code. Unfortuantely, my changed have resulted in an Access violation that occurs before the application InitInstance() is called. This makes it very difficult to debug. The only information I get is the following stack trace. > 64006108() ntdll.dll!_ZwCreateMutant@16() + 0xc bytes kernel32.dll!_CreateMutexW@12() + 0x7a bytes So, here are some sceanrios I've tried. - Turned on Exceptions-Win32 Exceptions-c0000005 Access Violation to break when Thrown. Still the most detail I get is from the above stack trace. I've tried the application with F10, but it fails before any breakpoints are hit and fails with the above stack trace. - I've stubbed out the bridge DLL so that it only has one method that returns a bool and that method is coded to just return false (no C# code called). bool DllPassthrough::IsFailed() { return false; } If the stubbed out DLL is compiled with the /clr flag, the application fails. If it is compiled without the /clr flag, the application runs. - I've created a stub MFC application using the Visual Studio wizard for multidocument applications and call DllPassthrough::IsFailed(). This succeeds even with the /clr flag used to compile the DLL. - I've tried doing a manual LoadLibrary on winmm.lib as outlined in the following note Access violation when using c++/cli. The application still fails. So, my questions are how to solve the problem? Any hints, strategies, or previous incidents. And, failing that, how can I get more information on what code segment or library is causing the access exception? If I try more involved workarounds like doing LoadLibrary calls, I'd like to narrow it to the failing libraries. Thanks. BTW, we are using Visual Studio 2008 and the project is being built against the .NET 2.0 framework for the managed sections.

  • Running out of label names in assembly

    - by mamidon
    Heyo, My class at college has us writing programs in assembly. I have never truly appreciated the ease of C until now. Now, when I program in assembly, I often have to make while/for/if loops and conditionals with labels eg: SKIP: ... COMP:ADD R1, R1, #0 ;Check for equality BRZ WHILEEND ... ;code inside the while loop JMP COMP ;Return to while loop WHILEEND: ... So, in this while loop (example) I have used 1 label for the subroutine and 2 more for the loop itself. I've run out of good label names for all the loops and branches I'm doing in assembly, what do you guys do to keep it varied and descriptive?
