  • Problem locating file in a classpath

    - by Gandalf StormCrow
    I'm trying to read in file content, ex : public void myMethod(){ FileInputStream fstream = new FileInputStream(fileLocation); // Get the object of DataInputStream DataInputStream in = new DataInputStream(fstream); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String strLine; while ((strLine = br.readLine()) != null) { .... .... ..... end while end method And I have at the begining of the class body private String fileLocation; and at the end of a class I have a getter and setter for it. Now I'm trying inject this file location from spring inside bean from this class and I specify the init-method of this class. But I get error cannot find the specified file as if its not on a classpath but it is inside war file? I'm building the project with maven and I put file in src/main/resources This is the error I get when trying to read file : Error: src\main\resources\ids.txt (The system cannot find the path specified) That is when I tried this : FileInputStream fstream = new FileInputStream("src\\main\\resources\\ids.txt"); how to reference the properly from the classpath? EDIT When I edit my code according to @BalusC solution , here is how it looks but I still get null error : ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); InputStream input = classLoader.getResourceAsStream("src/main/resources/ids.txt"); // Get the object of DataInputStream BufferedReader br = new BufferedReader(new InputStreamReader(input)); String strLine; while ((strLine = br.readLine()) != null) { .... .... ..... end while end method

  • Big numbers in C

    - by teehoo
    I need help working with very big numbers. According to Windows calc, the exponent 174^55 = 1.6990597648061509725749329578093e+123. How would I store this using C (c99 standard). int main(){ long long int x = 174^55; //result is 153 printf("%lld\n", x); } For those curious, it is for a school project where we are implementing the RSA cryptographic algorithm, which deals with exponentiating large numbers with large powers for encryption/decryption.

  • Django select max id

    - by pistacchio
    Hi, given a standard model (called Image) with an autoset 'id', how do I get the max id? So far I've tried: max_id = Image.objects.all().aggregate(Max('id')) but I get a 'id__max' Key error. Trying max_id = Image.objects.order_by('id')[0].id gives a 'argument 2 to map() must support iteration' exception Any help?

  • Why is my multithreaded Java program not maxing out all my cores on my machine?

    - by James B
    Hi, I have a program that starts up and creates an in-memory data model and then creates a (command-line-specified) number of threads to run several string checking algorithms against an input set and that data model. The work is divided amongst the threads along the input set of strings, and then each thread iterates the same in-memory data model instance (which is never updated again, so there are no synchronization issues). I'm running this on a Windows 2003 64-bit server with 2 quadcore processors, and from looking at Windows task Manager they aren't being maxed-out, (nor are they looking like they are being particularly taxed) when I run with 10 threads. Is this normal behaviour? It appears that 7 threads all complete a similar amount of work in a similar amount of time, so would you recommend running with 7 threads instead? Should I run it with more threads?...Although I assume this could be detrimental as the JVM will do more context switching between the threads. Alternatively, should I run it with fewer threads? Alternatively, what would be the best tool I could use to measure this?...Would a profiling tool help me out here - indeed, is one of the several profilers better at detecting bottlenecks (assuming I have one here) than the rest? Note, the server is also running SQL Server 2005 (this may or may not be relevant), but nothing much is happening on that database when I am running my program. Note also, the threads are only doing string matching, they aren't doing any I/O or database work or anything else they may need to wait on. Thanks in advance, -James

  • Is html font size using em still important

    - by JohnnyHTML
    In a web LOB web based SaaS product we are developing that we explicitly not support IE 6, only IE7/8, FF 3, Chrome, Opera, WebKit etc... which allow px resize as standard, is it still important to use em rather than px? Its a lot more work to consider the compute font size (size em are computed from their inheritance chain) especially when nesting html reuse components where a font-size has already been specified in an outer container.

  • Codechef practice question help needed - find trailing zeros in a factorial

    - by manugupt1
    I have been working on this for 24 hours now, trying to optimize it. The question is how to find the number of trailing zeroes in factorial of a number in range of 10000000 and 10 million test cases in about 8 secs. The code is as follows: #include<iostream> using namespace std; int count5(int a){ int b=0; for(int i=a;i>0;i=i/5){ if(i%15625==0){ b=b+6; i=i/15625; } if(i%3125==0){ b=b+5; i=i/3125; } if(i%625==0){ b=b+4; i=i/625; } if(i%125==0){ b=b+3; i=i/125; } if(i%25==0){ b=b+2; i=i/25; } if(i%5==0){ b++; } else break; } return b; } int main(){ int l; int n=0; cin>>l; //no of test cases taken as input int *T = new int[l]; for(int i=0;i<l;i++) cin>>T[i]; //nos taken as input for the same no of test cases for(int i=0;i<l;i++){ n=0; for(int j=5;j<=T[i];j=j+5){ n+=count5(j); //no of trailing zeroes calculted } cout<<n<<endl; //no for each trialing zero printed } delete []T; } Please help me by suggesting a new approach, or suggesting some modifications to this one.

  • C# equivalent of the C++ custom project Wizard

    - by gbjbaanb
    Hi., I have an existing wizard template created for VC++ from year back, ported to VS2008. It uses the custom wizard jscript/html templating system and DTE object. I've used this successfully for years, but now I want to create an entry for a standard C# project, I see there's no way to customise the C# project settings - the methods are for VC++ only. Is there something closely related to this for C# projects (or do I have to learn yet another way of creating a wizard for .net apps?)

  • How to determine which inheriting class is using an abstract class' methods.

    - by Kin
    In my console application have an abstract Factory class "Listener" which contains code for listening and accepting connections, and spawning client classes. This class is inherited by two more classes (WorldListener, and MasterListener) that contain more protocol specific overrides and functions. I also have a helper class (ConsoleWrapper) which encapsulates and extends System.Console, containing methods for writing to console info on what is happening to instances of the WorldListener and MasterListener. I need a way to determine in the abstract ListenerClass which Inheriting class is calling its methods. Any help with this problem would be greatly appreciated! I am stumped :X Simplified example of what I am trying to do. abstract class Listener { public void DoSomething() { if(inheriting class == WorldListener) ConsoleWrapper.WorldWrite("Did something!"); if(inheriting class == MasterListener) ConsoleWrapper.MasterWrite("Did something!"); } } public static ConsoleWrapper { public void WorldWrite(string input) { System.Console.WriteLine("[World] {0}", input); } } public class WorldListener : Listener { public void DoSomethingSpecific() { ConsoleWrapper.WorldWrite("I did something specific!"); } } public void Main() { new WorldListener(); new MasterListener(); } Expected output [World] Did something! [World] I did something specific! [Master] Did something! [World] I did something specific!

  • Problem with detecting the value of the drop down list on the server (servlet) side

    - by Harry Pham
    Client code is pretty simple: <form action="DDServlet" method="post"> <input type="text" name="customerText"> <select id="customer"> <option name="customerOption" value="3"> Tom </option> <option name="customerOption" value="2"> Harry </option> </select> <input type="submit" value="send"> </form> Here is the code on the Servlet Enumeration paramNames = request.getParameterNames(); while(paramNames.hasMoreElements()){ String paramName = (String)paramNames.nextElement(); //get the next element System.out.println(paramName); } When I print out, I only see, customerText, but not customerOption. Any idea why guys? What I hope is, if I select Tom in my option, once I submit, on my servlet I should able to do this: String paramValues[] = request.getParameterValues(paramName); and get back value of 3

  • DRY URL's in Django Javascript

    - by Noio
    I'm using Django on Appengine. I'm using the django reverse() function everywhere, keeping everything as DRY as possible. However, I'm having trouble applying this to my client-side javascript. There is a JS class that loads some data depending on a passed-in ID. Is there a standard way to not-hardcode the URL that this data should come from? var rq = new Request.HTML({ 'update':this.element, }).get('/template/'+template_id+'/preview'); //The part that bothers me.

  • ruby recursive regex

    - by Reed Debaets
    So why is this not working? I'm creating a regex that will match a formula (which is then part of a larger standard description). But I'm stuck here, as it doesn't appear to want to match embedded formulas within a formula. stat = /(Stat3|Stat2|Stat1)/ number_sym = /[0-9]*/ formula_sym = /((target's )?#{stat}|#{number_sym}|N#{number_sym})\%?/ math_sym = /(\+|\-|\*|\/|\%)/ formula = /^\((#{formula}|#{formula_sym}) (#{math_sym} (#{formula}|#{formula_sym}))?\)$/ p "(target's Stat2 * N1%)".match(formula).to_s #matches p "((target's Stat2 * N1%) + 3)".match(formula).to_s #no match p "(Stat1 + ((target's Stat2 * N1%) + 3))".match(formula).to_s #no match

  • jQuery Autocomplete with _renderItem and catagories

    - by LillyPop
    As a newb to jQuery im wondering if its possible to have both jQuery _renderItem (for custom list item HTML/CSS) AND the categories working together in harmony? Ive got my _renderItem working great but I have no idea how to incorporate categories into the mix. My code so far $(document).ready(function () { $(':input[data-autocomplete]').each(function () { $(':input[data-autocomplete]').autocomplete({ source: $(this).attr("data-autocomplete") }).data("autocomplete")._renderItem = function (ul, item) { var MyHtml = "<a>" + "<div class='ac' >" + "<div class='ac_img_wrap' >" + '<img src="../../uploads/' + item.imageUrl + '.jpg"' + 'width="40" height="40" />' + "</div>" + "<div class='ac_mid' >" + "<div class='ac_name' >" + item.value + "</div>" + "<div class='ac_info' >" + item.info + "</div>" + "</div>" + "</div>" + "</a>"; return $("<li></li>").data("item.autocomplete", item).append(MyHtml).appendTo(ul); }; }); }); The jQuery documentation for the autocomplete gives the following code example : $.widget("custom.catcomplete", $.ui.autocomplete, { _renderMenu: function (ul, items) { var self = this, currentCategory = ""; $.each(items, function (index, item) { if (item.category != currentCategory) { ul.append("<li class='ui-autocomplete-category'>" + item.category + "</li>"); currentCategory = item.category; } self._renderItem(ul, item); }); } }); Id like to get my custom HTML (_renderItem) and categories working together, can anyone help me to merge these two together or point me in the right direction. Thanks

  • zeroclipboard does not work when loaded with ajax call

    - by kylex
    I have the following code which works the way one would expect (click on the button and it copies the text in the input box): <script type="text/javascript" src="ABSOLUTE_LINK/ZeroClipboard.js"></script> <script type="text/javascript"> ZeroClipboard.setMoviePath( 'ABSOLUTE_LINK/ZeroClipboard.swf' ); </script> Copy to Clipboard: <input type="text" id="clip_text" size="40" value="Copy me!"/><br/><br/> <div id="d_clip_button">Copy To Clipboard</div> <script language="JavaScript"> echo "var clip = new ZeroClipboard.Client(); clip.setText( '' ); // will be set later on mouseDown clip.setHandCursor( true ); clip.setCSSEffects( true ); clip.addEventListener( 'load', function(client) { } ); clip.addEventListener( 'complete', function(client, text) { alert("Copied text to clipboard: " + text ); } ); clip.addEventListener( 'mouseOver', function(client) { } ); clip.addEventListener( 'mouseOut', function(client) { } ); clip.addEventListener( 'mouseDown', function(client) { // set text to copy here clip.setText( document.getElementById('clip_text').value ); } ); clip.addEventListener( 'mouseUp', function(client) { } ); clip.glue( 'd_clip_button' ); </script> However, when this code is loaded using an ajax call, the functionality disappears. Is there anything I can do to get this working when it's called via ajax?

  • Best way to author man pages?
