  • Does anybody actually use the permissions policy controls in tomcat?

    - by stu
    While I can appreciate the point of the fine granularity in which you can enable security for every single little thing for each individual application in tomcat, in reality, it's an insane pain in the ass. Every single file, socket, everything for every single application. Sure if you're writing a "hello world" application, it's not too much to ask, but an enterprise sized application? That's insane. Does anybody actually use it, or does everybody just say "*" for everything?

  • What's the correct way to instantiate an IRepository class from the Controller?

    - by GenericTypeTea
    I have the following project layout: MVC UI |...CustomerController (ICustomerRepository - how do I instantiate this?) Data Model |...ICustomerRepository DAL (Separate Data access layer, references Data Model to get the IxRepositories) |...CustomerRepository (inherits ICustomerRepository) What's the correct way to say ICustomerRepository repository = new CustomerRepository(); when the Controller has no visibility to the DAL project? Or am I doing this completely wrong?

  • InfoPath: How to display a third column of a datasource?

    - by Michael Bray
    I have an InfoPath 2007 browser-enabled form that has a datasource with three columns, let's say columns A, B, and C. I have a dropdown that is keyed to column A and displays column B. Column C contains some data that I want to display in an expression box, and that I also want to use in some data validation against another field on the form. I'm looking for some help on how to reference that column C for displaying and use in validation. Thanks!

  • Revision, Quadratic Time

    - by stan
    I am not sure if you can post revision programming questions in here but i am stuck with some algorithms revision If an algorithm is quadratic it takes time proportional to the number of n^2 ? So if the slides say its almost 1/2 the square of n records is this the same as saying (n^2 * 0.5) Thanks

  • How important is it for me to pool my connections?

    - by Rio Mango
    It has been suggested to me that I rearrange my code to "pool" my ADO connections. On each web page I would open one connection and keep using the same open connection. But someone else told me that was important 10 years ago but is not so important now. If I make, let's say, 5 db calls on a web posting, is it problematic to be using 5 separate connections that I open/close?

  • PHP Sessions data lost when changing directory?

    - by Ineffable
    I've got a simple login system using PHP sessions, but just recently it seems that if you visit pages not in a certain directory (/login/) you will always be flagged as not logged in, even when you are. It seems that my session data is being lost when I change directories (say, to /login/user/). I don't think I've touched the code myself since the problem appeared, is there something my web host could have done to my PHP installation that would delete the session data, and is there a workaround?

  • C++ header files and variable scope

    - by MrDatabase
    I want to organize my c++ variables and functions in the following way: function prototypes in a header file "stuff.h", function implementation in "stuff.cpp", then say #include "stuff.h" in main.cpp (so I can call functions implemented in stuff.cpp). So far so good. Now I want to declare some variables in stuff.cpp that have global scope (so I can modify the variables in functions implemented in stuff.cpp and main.cpp). This doesn't seem to work. How can I do this?

  • Naked Objects. Good or Bad

    - by Midhat
    I have recently been exposed to naked objects. It looks like a pretty decent framework. However I do not see it in widespread use like say, Spring. So why is this framework not getting any mainstream application credit. What are its shortcomings as you see?

  • Looking for a fast hash-function.

    - by Julian
    Hello, I'm looking for a special hash-function. Let's say I have a large list of strings, if I order them by their hash-values they should be ordered quasi randomly. The most important point is: it must be super fast. I've tried md5 and sha1 and they're using to much cpu power. Clashes are not a problem. I'm using javascript, so it shouldn't be too complicated to implement.

  • Using "null" in jQuery functions. Is this okay?

    - by Nick
    My database consists of some entries which are NULL (so they don't affect max, min, etc..). When I pull all of the data from the database, I need to repopulate form fields with the values. Using .val(value) where value = NULL seems to work without any problems, but I'm not sure if this is a valid way to go about this. It doesn't say anything in the jQuery documentation (that I can find) about using NULL as parameters to functions.

  • Sorting Custom Objects with Parameter in VB.Net/C#

    - by Jeffrey Kern
    Let's say I have a custom object of Foo Is there anyway I can sort through a list of these objects, like list<of foo>.sort() and also be able to sort this list with a passable parameter. which will influence the sort? list<of foo>.sort(pValue) I'm guessing I'll need to define two separate sorts, but I am not sure. Thanks!
