  • How to add imports to groovysh on startup?

    - by ipolevoy
    I'm working on a project where I'd like users to experiment with Java classes on Groovysh. I'd like to make it convenient for them and want to import certain packages by default, when groovysh starts up so that users would not have to re-type the same imports every time they start the shell. Does anyone know how to accomplish this? Thanks in advance, igor

  • How do I get rid of LD_LIBRARY_PATH at run-time?

    - by Kjir
    I am building a C++ application that uses Intel's IPP library. This library is installed by default in /opt and requires you to set LD_LIBRARY_PATH both for compiling and for running your software (if you choose the shared library linking, which I did). I already modified my configure.ac/Makefile.am so that I do not need to set that variable when compiling, but I still can't find the shared library at run-time; how do I do that? I'm compiling with the -Wl, -R/path/to/lib flag using g++

  • Check if webbased CertEnroll will succeed

    - by Tim Mahy
    Hi all, for a project we will be doing webbased certificate enrollment, in Vista / Win7 combination with IE this gives some problems if the user does not import the root certificate first and then changes a lot of default IE settings (Enable ActiveX not marked safe for scripting etc....). I was wondering if any of you ever created a test VB or Javascript to test that all the settings are OK. So it can be used by the user before he starts the enrollment process.... greetings, Tim

  • jQuery toggle caching / cookies

    - by user1706680
    I’m using the jQuery toggle function for my navigation. By default the Authors toggle is visible, the Archives toggle is closed. http://jsfiddle.net/TeDFs/4/ My problem is that when the users switches to another page the toggles reset themselves. For example, when the user closes the Authors toggle and opens the Archive toggle and then navigates to another page the default settings are loaded. I read that it’s possible to store the settings via cookies but I’m absolutely new to jQuery and it would be great if somebody could help me out! HTML <div id="authors" class="widget"> <h2 class="widget-title-visible">Authors</h2> <div class="toggle"> <div class="submenu"> <ul> <li>Name 1</li> <li>Name 2</li> <li>Name 3</li> <li>Name 3</li> </ul> </div> </div> <div id="archives" class="widget"> <h2 class="widget-title">Archiv</h2> <div class="toggle hidden"> <div class="submenu"> <ul> <li>November 2012</li> <li>Oktober 2012</li> </ul> </div> </div> </div>? jQuery function toggleWidgets() { jQuery('.widget-title').addClass('plus'); jQuery('.widget-title-visible').addClass('minus'); jQuery('.widget-title').click(function() { $(this).toggleClass('plus').toggleClass('minus').next().toggle(180); }); jQuery('.widget-title-visible').click(function() { $(this).toggleClass('minus').toggleClass('plus').next().toggle(180); }); } jQuery(document).ready(function() { toggleWidgets(); } )? CSS .hidden{ display:none; } .plus { background: url(http://moargh.de/daten/sidebar_arrows.png) 0 5px no-repeat; padding: 0 0 0 12px; } .minus { background: url(http://moargh.de/daten/sidebar_arrows.png) 0 -10px no-repeat; padding: 0 0 0 12px; }

  • Possible form field types per model field type

    - by Jonathan
    Django's documentation specifies for each model field type the corresponding default form field type. Alas, I couldn't find in the documentation, or anywhere else, what form field types are possible per model field type. Not all combinations are possible, right? Same question for widgets...

  • PHP - Cannot modify header information...

    - by Scott W.
    Hi, I am going crazy with this error: Cannot modify header information - headers already sent by... Please note that I know about the gazillion results on google and on stack overflow. My problem is the way I've constructed my pages. To keep html separate from php, I use include files. So, for example, my pages look something like this: <?php require_once('web.config.php'); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Login</title> <link rel="shortcut icon" href="images/favicon.gif"/> <link rel="shortcut icon" href="images/favicon.ico"/> <link rel="stylesheet" type="text/css" href="<?php echo SITE_STYLE; ?>"/> </head> <body> <div id="page_effect" style="display:none;"> <?php require_once('./controls/login/login.control.php'); ?> </div> </body> </html> So, by the time my php file is included, the header is already sent. Part of the include file looks like this: // redirect to destination if($user_redirect != 'default') { $destination_url = $row['DestinationUrl']; header('Location:'.$user_redirect); } elseif($user_redirect == 'default' && isset($_GET['ReturnURL'])) { $destination_url = $_GET['ReturnURL']; header('Location:'.$destination_url); } else { header('Location:'.SITE_URL.'login.php'); } But I can't figure out how to work around this. I can't have the header redirect before the output so having output buffering on is the only thing I can do. Naturally it works fine that way - but having to rely on that just stinks. It would be nice if PHP had an alternative way to redirect or had additional parameters to tell it to clear the buffer.

  • Mcafee PCI Compliance failing on Session ID cookie?

    - by frio80
    Hello there. I am attempting to obtain PCI compliance for my site but the Mcafee security scan has thrown a: Potential Sensitive Persistent Cookie Sent Over a Non-Encrypted (SSL) Channel Drupal (default behavior) sets a session cookie when you simply arrive at the site. This is causing the problem. Clearly, the entire site shouldn't be under SSL; plenty of other sites set session cookies like this. What gives?

  • using ruby-debug with jruby-1.5.0

    - by brad
    Release notes say that ruby-debug is installed by default. I'm using rvm. In my rails app I figured something as simple as script/server --debugger would suffice, but it complains that the ruby-debug gem isn't installed, suggests using gem install ruby-debug, which of course doesn't work (building native extensions) and is contrary to the docs anyway. Just wondering if anyone's had any luck using the built in ruby-debug in jruby 1.5 and what one needs to do in order run jruby in debug mode

  • How to set a keybinding which is valid in all modes in Emacs

    - by AnotherEmacsLearner
    Hi, I've configured my emacs to use M-j as backward-char by (global-set-key (kbd "M-j") 'backward-char) ; was indent-new-comment-line in my .emacs file. This works fine in many modes (text/org/lisp). But in c++-mode & php-mode it is bound to the default c-indent-new-comment-line How can I bind M-j to use backward-char in these modes too. And in general for ALL modes. Thanks, AnotherEmacsLearner

  • setting user.dir system property in JBoss 5.1

    - by Spiderman
    In JBoss 4.2.3 the System property 'user.dir' is defined to be <JBoss-root>/bin when I ran the same application on JBoss 5.1 I noticed that it cannot find the System property user.dir why there is no default definition for version 5.1? and how can I define it manually? I followed this suggestion and added my property into properties-service.xml but it had no affect and still JBoss couldn't find the system:user.dir value.

  • Ruby on Rails: Can I do a "link_to" to call a create action?

    - by sjsc
    How would I correctly call the create action from a link_to? Here's the create action: def create recipe = Recipe.create(:name => "French fries") redirect_to recipe end For example, I thought something like this might work: <%= link_to "Create a default recipe", recipe_path, :method => :post %> I'm not sure if that's a recommended (or even correct) way to do it. Any idea?
