  • Local variables in java

    - by Mandar
    Hello , I went through local variables and class variables concept. But I had stuck at a doubt " Why is it so that we cannot declare local variables as static " ? For e.g Suppose we have a play( ) function : void play( ) { static int i=5; System.out.println(i); } It gives me error in eclipse : Illegal modifier for parameter i; I had this doubt because of the following concepts I have read : Variables inside method : scope is local i.e within that method. When variable is declared as static , it is present for the entire class i.e not to particular object. Please could anyone help me out to clarify the concept. Thanks.

  • Java output file doesnt recognise \n as linebreak

    - by oderebek
    for a Java project for a University Class I have a method that saves ASCII images as a uniline string and another method called toString rebuilds this ASCII image and returns as a string. When I run my program on the Eclipse my output looks on console alright and multiline, and there are line breaks where they should be. But when I run it with the command line with a redirected outputfile java myprogram < input output the text in the output is uniline without line breaks Here is the code of the method public String toString(){ String output = ""; for(int i=0; i<height; i++){ output=output+image.substring(i*width, i*width+width)+"\n"; } return output; } What should I do so I can get a multiline output text file

  • how to debug java mail

    - by voipp
    My goal is to debug my programm, that uses java mail library(including javax.mail and com.sun.mail). So i decided first to download java mail sources and compile it with option -g. I go to the java mail sources and binaries , downloaded them. Somehow sources store in jar but not just zip. Ok. Then i decided to decompile jar into zip with JAD plugin in eclipse. After decompiling i receive empty directory. I downloaded jad.exe and run it , but it throwed a message : JavaClassFileParseException: Not a class file. It says it decompiles only classes, but what about jars? Is it so hard just store sources in fu** zip ???!!!!

  • Can I find and import files into an Ant buildfile at run time?

    - by Mnementh
    I want to create an Ant buildfile, that includes some files as a sort of plugin. So if I want to activate a feature in a project - say pmd-checking - I copy a pmd.xml in a directory and the build.xml get on the start the idea, that pmd.xml exists and imports it, so that new targets can be available to the build. But the 'import' task can only be used as a top-level task, so I have no idea how to relize this functionality. Is this possible with Ant and if so, how can I do it? EDIT: I would prefer a solution, that allows new targets to show up in the listing presented by ant -p.

  • deprecated readLine() What to change?

    - by user1681751
    I'm trying to get this to work in the eclipse, but the "readLine" is striked through and a notice says it is depreciated, the code works, albeit not the "while ((var2 = var5.readLine()) != null) {" bit.. So I'm wondering how to fix it, a java beginner. String var2 = ""; HttpURLConnection var3 = null; DataOutputStream var4 = null; DataInputStream var5 = null; ...more code here.... try { var5 = new DataInputStream(var3.getInputStream()); while ((var2 = var5.readLine()) != null) { System.out.println("Server Response " + var2); ScreenShotHelper.mc.thePlayer.addChatMessage("\u00a7aSuccessfully uploaded screenshot! Direct link:"); ScreenShotHelper.mc.thePlayer.addChatMessage("\u00a7a" + var2); } var5.close(); }

  • How important is caching for a site's speed with PHP?

    - by benhowdle89
    I've just made a user-content orientated website http://www.humanisms.co.uk Its done in PHP, MySQL and jQuery's AJAX, at the moment there is only a dozen or so submissions and already i can feel it lagging slightly when it goes to a new page (therefore running a new mysql query) Is it most important for me to try and optimise my mysql queries (by prepared statements) or is it worth in looking at CDN's (amazon s3) and caching (much like the WordPress plugin WP Super Cache) which works by serving static HTML files when there hasnt been new content submitted. Which route is the most beneficial, for me as a developer, to take, ie. where am i better off concentrating my efforts to speed up the site?

  • Get real image width and height with Javascript in Safari/Chrome?

    - by Frank Bannister
    I am creating a jQuery plugin. How do I get real image width and height with Javascript in Safari? Following works with Firefox 3, IE7 and Opera 9: var pic = $("img") // need to remove these in of case img-element has set width and height pic.removeAttr("width"); pic.removeAttr("height"); var pic_real_width = pic.width(); var pic_real_height = pic.height(); But in Webkit browsers like Safari and Google Chrome values are 0... Doing this on server side is not an option.

  • Strange/simple batch question regarding Java/Ant

    - by Monster
    For my company, I'm making a batch script to go through and compile the latest revisions of code for our current project. I'm using Ant to build the class files, but encountered a strange error. One of the source files imports .* from a directory, where there are no files (only folders), and in fact, the folders needed are imported right after. It compiles perfectly fine in Eclipse, but I'm using an Ant script to automate it outside of the IDE, and Javac throws an error when it encounters this line. Is there any automated procedure I can use to ignore/suppress this error with javac in Ant? I'd even go so far as to create a dummy file in the importing directory, but all of that in contained in a Jar file I don't wish to have to decompress and then recompress with the dummy file. Thanks!

  • Joomla Development - Allow Direct File Access AND use Joomla-intern Framework

    - by Email
    Hi As usual you write in Joomla Development defined('_JEXEC') or die('Restricted access'); I make a plugin which needs access from Paypal/IPN, so i exclude that in that specific file. BUT I also need to use the Joomla-intern Variables to access the Database, so i tried this: require("../filewithaccesstoframework.php"); OR even $baseurl = $_SERVER['HTTP_HOST']; $baseurl ="http://".$baseurl."/configuration.php"; require($baseurl); By using the first code it displays "Restircted Access" since it seems to take this from the included file which i can't skip to put-in-there. The second code does not seem to recognize the Variables used in configuration.php like $host, $db, $password. the file configuration.php is chmod 444 Why this happens and is there a workarround to allow direct access to a file AND using the Joomla intern Framework (Variables, Functions)?

  • Auto update CSS from SASS/SCSS in Rails?

    - by Vulgrin
    Maybe I'm confused on how SASS/SCSS works within Rails (2.3.8.) but I was under the impression that if I included the option Sass::Plugin.options[:always_update] = true that whenever I changed my SCSS file and then hit the page (controller) again, the SCSS would recompile. I can't seem to get this to work, and can't seem to find a good tutorial / example for it. I've tried setting the above property in the Environment.rb file, but it didn't seem to do anything. I tried putting it in its own initializer with require 'sass' but that doesn't seem to work either. What am I missing? Or am i just forced to keep a terminal open with a sass --watch command running to be able to rapidly debug / change my styles? thx

  • What does Rails script/server -d do differently that would cause a cells template to not be found

    - by Brian Deterling
    I'm using cells. I used the generator to create a cell so the path to my template was automatically chosen to be app/cells/displayer/table.html.erb where displayer is the name of the cell and table is the name of the state. When I run script/server in the foreground, everything works perfectly. But when I run script/server -d, I get "Missing template displayer/table.erb in view path app/cells:app/cells/layouts". Even if I change table.html.erb to table.erb, I see the same message - the ActionView code is checking both but not finding either. Even if you're not familiar with cells, does anyone know what happens differently in daemon mode related to view paths? In this case, it appears that the plugin is not correctly registering the view path.

  • JavaScript - Textarea Selection

    - by brad
    The Problem I am working on an in-browser editor within a textarea. I have started looking for some information on dealing with textarea selection and found this jQuery plugin that does some simple manipulation. However, it doesn't explain what's going on. The Question Where can I find a good resource on Textarea Selection in JavaScript, preferably with a description of both pre-DOM3 and post-DOM30 scenarios? [Edit] In a great answer from Borgar, I have found several different places to start with contentEditable, selectionStart, and selectionEnd. I'll be looking into these things and posting any good tutorials I might find.

  • Trying to load a DLL with LoadLibrary and get R6034 "An application has made an attempt to load the

    - by nonoitall
    I'm writing a wrapper program that loads Winamp input plugins. I've got it working well so far with quite a few plugins, but for some others, I get an error message at runtime when I attempt to call LoadLibrary on the plugin's DLL. (It seems to happen mostly with plugins that were included with Winamp.) A dialog appears and gives me the error code and message above. This happens, for example, with the in_flac.dll and in_mp3.dll plugins (which come with Winamp). Any ideas on how I can remedy this situation?

  • What benefits can Java developer have from moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse on it, so there will be no big difference. Guys, who use Java on *NIX, could you please give me some real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • emacsclient -eval "(insert \"something\")" is not working for me

    - by manu
    I recently upgraded to Ubuntu 10.04 which comes with Emacs 23. I need Jabref to push citations to Emacs. However, despite I installed the Jabref plugin to push citations through emacsclient, it's not working. I did my testing, and read some of the Emacs Lisp Intro. Some commands do work, for instance if I type (in the console): emacsclient --eval "(switch-to-buffer \"*sratch*\")" the emacs windows switches to that buffer. However if I issue an insert command: emacsclient --eval "(insert \"do you see me?\")" no text is inserted in the current buffer. Does Emacs 23 changed something about insert?

  • snipMate only working on empty buffer?

    - by JesseBuesking
    I'm attempting to use snipMate with sql files, however it doesn't seem to work when editing an existing file. If I create a new empty buffer (no file; e.g. launch gvim from the start menu), and set the filetype to sql (:set ft=sql), it works. However, if I then try to open a sql file (e.g. :e c:\blah.sql) and edit it, snipMate no longer works. What gives!? Setup: gvim vim 7.3 Windows 7 snipMate 0.84 Also, I do in fact have filetype plugin on in my .vimrc file. edit Apparently if I open an empty buffer, set the filetype to sql, then save to file using w c:\blah.sql, I now have a sql file open AND snipMate continues to work. edit Here's a gist of my current .vimrc in case it helps: https://gist.github.com/3946877

  • Again, what version control system to choose?

    - by Ivan
    Please excuse me for probably a newbie hundred-times-chewed question. I have no experience with version control systems except of using Visual Source Safe in a project done by 2 people sitting in front of each other (which has shown VSS quite sack of boulders, not anything useful). Right now I am looking to grok-in using some modern VCS. Here are the preferences in descending priority order: Platform-agnostic. Pretty pleasant to use With Visual Studio 2010 on Windows as well as With NetBeans 6.9 and Eclipse 3.6 on Linux and Mac. Convenient and efficient for mutually-dependent projects done by teams of 1-10 and consisting of files of quite a diverse selection of types. Including early-stage projects with unstable design and experimenting. Modern. As fresh and future-technology-feature-rich as possible. Free & open-source. Should I take a closer look at SVN, Mercurial, GIT, Bazaar, or something else?

  • 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

  • bgiframe appears in front of jquery modal dialog's overlay in IE6

    - by Ryan
    When I look at jquery ui's demo modal dialog (http://jqueryui.com/demos/dialog/#modal) in IE6 the bgiframe is appearing on top of the background overlay. So instead of seeing a black/gray stripe pattern, there is just a white background covering the page with the word "false" in the upper left corner. Is bgiframe broken with the latest version of jqueryui? Is there a quick way to repair this problem with bgiframe? If not, is there a plugin that hides selects when a modal dialog is shown? The ie6 z-index issue with selects is the reason I was using bgiframe in the first place.

    Hello, i've just downloaded Moodialog, a Mootools plugin for dialog, but i have a problem. If content is set via parameters it will be text and not html. Can you help me change the function to accept html? I suppose that this is the code to be edit. setContent: function(){ var content = Array.from(arguments); if (content.length == 1) content = content[0]; this.content.empty(); var type = typeOf(content); if (['string', 'number'].contains(type)) this.content.set('text', content); else this.content.adopt(content); return this; }, I tried to edit 'text' in 'html', but it will not work.

  • Web2py controllers with parameters?

    - by nickfranceschina
    I am building an app using Web2py framework... I don't want to have to use the request object to get all of the querystring parameters, instead I'd like to build my controller with named parameters and have the router unpack the querystring (or form data) dictionary into the named parameters and call my controller. so instead of a controller method of create_user(): where I would use the global request() object and look through the vars list... I would prefer instead to have create_user(first_name, last_name, email): like I see in other MVC platforms. is this possible in Web2py already? or is there a plugin for it? or do I need to add that myself?
