  • how to stop directory structure from being viewable in J2EE apps

    - by Omnipresent
    in a J2EE app if user explicitly takes out the the ending page name then what is the best way to not show the directory structure? Example: /mycoolapp/somefolder/test.jsp /mycoolapp/somefolder/ -- this will show all the files under 'somefolder' What is the best way to redirect or show the user a page saying 'not where you belong'. I want to avoid providing index.jsp in all the folders/subfolders of my application. Appserver being used is GlassFish. Also the app is using Struts2 framework, though not all of the code is in struts2. Some code is using traditional Servlets

  • How to configure multiple mappings using FluentHibernate?

    - by chris.baglieri
    First time rocking it with NHibernate/Fluent so apologies in advance if this is a naive question. I have a set of Models I want to map. When I create my session factory I'm trying to do all mappings at once. I am not using auto-mapping (though I may if what I am trying to do ends up being more painful than it ought to be). The problem I am running into is that it seems only the top map is taking. Given the code snippet below and running a unit test that attempts to save 'bar', it fails and checking the logs I see NHibernate is trying to save a bar entity to the foo table. While I suspect it's my mappings it could be something else that I am simply overlooking. Code that creates the session factory (note I've also tried separate calls into .Mappings): Fluently.Configure().Database(MsSqlConfiguration.MsSql2008 .ConnectionString(c => c .Server(@"localhost\SQLEXPRESS") .Database("foo") .Username("foo") .Password("foo"))) .Mappings(m => { m.FluentMappings.AddFromAssemblyOf<FooMap>() .Conventions.Add(FluentNHibernate.Conventions.Helpers .Table.Is(x => "foos")); m.FluentMappings.AddFromAssemblyOf<BarMap>() .Conventions.Add(FluentNHibernate.Conventions.Helpers .Table.Is(x => "bars")); }) .BuildSessionFactory(); Unit test snippet: using (var session = Data.SessionHelper.SessionFactory.OpenSession()) { var bar = new Bar(); session.Save(bar); Assert.NotNull(bar.Id); }

  • Scrubbing IPv4 dotted-quad addresses in SQL

    - by pilcrow
    Given a table containing dotted quad IPv4 addresses stored as a VARCHAR(15), for example: ipv4 -------------- 172.16.1.100 172.16.50.5 172.30.29.28 what's a convenient way to SELECT all "ipv4" fields with the final two octets scrubbed, so that the above would become: ipv4 ------------ 172.16.x.y 172.16.x.y 172.30.x.y Target RDBMS is postgresql 8.4, but the more portable the better! Thanks.

  • DIV overlap on top of submit order INPUT button not working right in IE7

    - by Lauren
    I created a test account at www.avaline.com: username: [email protected] pass:test02 I'll keep the account around so you can see what's going on with this submit button without going through the registration process (and needing to fill in a fake address, etc). If logging in doesn't work, you can create your own test account though. Make sure at least one item is in your shopping cart, hit "proceed to checkout", and check off "PayPal" as your payment method (this way the payment won't go through for testing purposes). Once you're on the "review and submit" page, in IE7 (at least), hover over the "pay with Paypal" button, and you'll see that the cursor is a hand when you hover over the text or the button border, but it's a regular arrow when you hover over the button part. If you try clicking on the arrow-cursor area, you'll get the error that you should see...but if you click on the hand-cursor area, you get redirected to the paypal page. In FF, the #hidSubm DIV covers the "Pay with Paypal" button. Why isn't it working in IE7?

  • RIA Services and Validation

    Earlier today, my SilverlightTV recording on RIA Services and Validation went online. I used validation as a feature area to focus on this first recording on RIA Services, because I think it illustrates both the RIA Services value proposition and key elements of the vision around the project in a very direct manner. Specifically: Focus on end-to-end solutions for data scenarios. It is not sufficient to just address querying data or submitting some changes, but about providing the infrastructure...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Silverlight TV 18: WCF RIA Services Validation

    Just prior to MIX10, Nikhil Kothari appears on the show to demonstrate some of the key advantages around validation when using WCF RIA Services. He demonstrates how to use a Domain Service to expose your domain model and how to create a custom service method to further filter your data server side. Nikhil also shows how the Domain Services generates validation rules using the database attributes such as required fields or maximum string lengths. Other topics Nikhil covers: Domain service generated...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Is there a way to HIDE a file/dir from a specific user/group?

    - by Iraklis
    I'm setting up ACL permissions in CENTOS. I'm getting close to the structure that I have in mind however one piece is missing for completing the puzzle. Is there any way to HIDE a file/directory from a specific user/group? I'm not talking about not being able to read, change dir to it. I want to completely hide it from the specific user/group (not to show up on ls -la).

  • Removing Windows 2003 Server and Domain from Network

    - by Mike Ruford
    I have a Windows-2003-Server with five computers (Windows XP) accessing it using a domain. I would like to remove the server and the domain and go straight to peer to peer (file sharing via a NAS). We are moving our email to an Exchange Hosting Provider. We no longer need people to log in from different computers and have their desktops available from any computer on the network (however, I do want to get those files off of this setup). Any suggestions?

  • Mozilla invite les femmes a être plus présentes dans les métiers de l'IT, avec son projet WoMoz

    Mise à jour du 25.03.2010 par Katleen Mozilla invite les femmes a être plus présentes dans les métiers de l'IT, avec son projet WoMoz Nous avions déjà évoqué ce sujet en février : les femmes sont minoritaires dans les métiers des nouvelles technologies. Il y a peu de développeuses, les hommes sont clairement plus présents dans les métiers de l'IT. Dans l'open source, les chiffres sont encore plus prononcés. Seuls 3% de femmes y seraient recensées, contre 25 % pour le monde propriétaire (chiffres provenants d'une étude de la Commission Européenne). D'où l'idée de lancer un projet pour les femmes dans le monde du libre et en particulier chez Mozilla. WoMoz (Women and Mozilla) a ét...

  • LaTeX - Making a lighter version of text, like anti-bold?

    - by Rory
    I'm making a LaTeX document for someone. A certain piece of text looks "bold" for them, even though I'm not using the \textbf command. It's just a normal default LaTeX font. Is there any command to make a 'lighter version', i.e. make the text lighter, thinner? Something that looks to normal text, what normal text looks to bold?

  • facebook connect: thumbnail images broken up in FB.Connect.streamPublish pop-up prompt, and on wall

    - by Hoff
    hi there! I'm using facebook connect so that users can publish comments they are leaving on my site on their facebook wall as well. It works as intended, except that in the confirmation pop up, the thumbnail image i provide is broken. Looking at the source, I can see that facebook prepended my image url like this: from: http://www.mysite.com/path/to/my/image.jpg to: http://platform.ak.fbcdn.net/www/app_full_proxy.php?app=303377111175&v=1&size=z&cksum=41a391c9f3a6f3dde2ede9892763c943&src=http%3A%2F%2Fwww.mysite.com%2Fpath%2Fto%2Fmy%2image.jpg The image on the facebook user's wall has the same prepended url, and is also broken for a couple of minutes, after which it's showing up correctly. But obviously, having a broken image in the confirmation window and on your wall for a couple of minutes is not a good experience... Has anybody experienced the same / knows how to work around this issue? Thanks a lot in advance! Martin PS: here's the part of the js call, if it's of any use... attachment = { 'media': [{ 'type': 'image', 'src': 'http://www.mysite.com/path/to/my/image.jpg', 'href': 'http://www.mysite.com/the/current/page' }] }; FB.Connect.streamPublish(user_message, attachment, action_links, target_id, user_message_prompt, fbcallback, false, actor_id)

  • Where to learn about matrices?

    - by GummyBears
    I am programming in Ruby and have wanted to learn about matrices but I can't find any resources for actually learning about them. Are there any good tutorials on matrices and programming? It would be nice if it would be in ruby but other languages are fine too.

  • Datatype to use for collection of QT buttons

    - by different
    Hi Everyone, I am brand new to QT and need to develop the Mancala game. Since I'm brand new to the QT environment, my plan it to keep things very simple. I will be using the "Push Button" widget as pieces on the game. Since two players play this game, my idea is to have to arrays of buttons. One array for player 1 and the other for player 2. My question is since I am using "Push Button" widgets, how can I group them to iterate through? I notice that QT has both the array and vector data types but I'm confused on how these data types can be used to "group" the buttons. Does anyone know of any sample code or tutorials to look at to learn more? Thanks for your time and any input provided.

  • WPF treeview with rounded corners

    - by BrettRobi
    I have a treeview in a UI full of rounded corners, so I'd like the treeview to match. Is it possible in xaml to change the border of a treeview to have rounded corners? I've thought about hiding the border and putting the treeview inside a rounded rectangle, but this loses real-estate and seems in-elegant. Any ideas?

  • How do I change the background color of the column with the expanders in Eclipse?

    - by Pridkett
    Recently after scorching my retinas from the garish white background in Eclipse, I found some of the excellent posts about how to change the colors so it uses sane (i.e. dark background) colors in the editor. However, one problem present in all solutions is that background of the column with the expanders for code folding is always white. Is there a way to change the background of that column? Here's a screenshot of the problem: I'm not the only person that has this problem, as shown in the screenshots for the following questions: Dark Color Scheme for Eclipse Color Themes for Eclipse (application of color schemes results in this issue on a Mac, no idea about PC) I know that the problem is not language specific as it happens in Java, Python, HTML, and everything else. Any hints on where in the pages of preferences this setting is?
