  • problem with overriding autologin in spring security?

    - by sword101
    greetings everybody iam using spring security 3 remember me service as follows <http> <remember-me/> ....</http> and i want to perform some logic in the autologin so i tried to override the AbstractRememberMeServices as follows: package com.foo; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.security.core.Authentication; import org.springframework.security.web.authentication.RememberMeServices; public abstract class AbstractRememberMeServices implements RememberMeServices{ @Override public Authentication autoLogin(HttpServletRequest arg0, HttpServletResponse arg1) { System.out.println("Auto Login"); return null; } @Override public void loginSuccess(HttpServletRequest arg0, HttpServletResponse arg1, Authentication arg2) { System.out.println("Login Success"); } } but the autologin occurs with no action,the user auto login but the print statement is not printed? what's wrong?

  • What is the structure of a (Data Access) Service Class

    - by jiewmeng
    I learnt that I should be using service classes to persist entities into the database instead of putting such logic in models/controllers. I currently made my service class something like class Application_DAO_User { protected $user; public function __construct(User $user) { $this->user = $user } public function edit($name, ...) { $this->user->name = $name; ... $this->em->flush(); } } I wonder if this should be the structure of a service class? where a service object represents a entity/model? Or maybe I should pass a User object everytime I want to do a edit like public static function edit($user, $name) { $user->name = $name; $this->em->flush(); } I am using Doctrine 2 & Zend Framework, but it shouldn't matter

  • Psuedo-Backwards Builder Pattern?

    - by Avid Aardvark
    In a legacy codebase I have a very large class with far too many fields/responsibilities. Imagine this is a Pizza object. It has highly granular fields like: hasPepperoni hasSausage hasBellPeppers I know that when these three fields are true, we have a Supreme pizza. However, this class is not open for extension or change, so I can't add a PizzaType, or isSupreme(), etc. Folks throughout the codebase duplicate the same "if(a && b && c) then isSupreme)" logic all over place. This issue comes up for quite a few concepts, so I'm looking for a way to deconstruct this object into many subobjects, e.g. a pseudo-backwards Builder Pattern. PizzaType pizzaType = PizzaUnbuilder.buildPizzaType(Pizza); //PizzaType.SUPREME Dough dough = PizzaUnbuilder.buildDough(Pizza); Is this the right approach? Is there a pattern for this already? Thanks!

  • Class Design - Returning a List<Object> From <Object>

    - by Mike
    Given a simple class: public class Person { public string FirstName; public string LastName; public string GetFullName() { return FirstName + LastName; } } The user of this class will populate a List<Person> object by reading an Xml file or some other data source. Should the logic for populating the List be in the Person class or should it just remain in the calling class? In other words, should there be a public List<Persons> GetPersons() method in the Person class or in the calling class? Or should the data accessor be in another class altogether? I know this is a rather simplistic question but I'm just curious how others typically do it.

  • get current logged in userID in aspnet mvc membership

    - by FosterZ
    hi, i am trying to show a list of users of my application "school", when admin logs in then he can view all the users in list but when school principals logins, he should get only users of his school, So i thought to get the current loggedIn userId first and then by that userId i'll get schoolId since userId is foreign key in school table...once i'll get the schoolId i can show the members of that school. But my problem is how to get the UserID of currently loggedIn. I'm using MVC 1.0 Asp.Net -- "Membership" if my logic above is wrong then please tell me the alternate good idea, so that principal can see only his users list..

  • Best approach for authorisation rules

    - by Maciej
    I'm wonder about best approach of implementation auth. rules in Client-Server app using Business Objects. I've noticed common tactic is: - on DB side: implement one role for application, used for all app's users - definition users right and roles and assign users to proper group - Client side: add to Business Object's getters/setters rights checker allowing write / display data for particular user My concern is if this is really good approach from security perspective. It looks DB sends all information to Client, and then client's logic decide what to display or not. So, potentially advanced user can make query from their box and see/change anything. Isn't it?

  • Problem creating ObjectContext from different project inside solution.

    - by Levelbit
    I have two projects in my Solution. One implements my business logic and has defined entity model of entity framework. When I want to work with classes defined within this project from another project I have some problems in runtime. Actually, the most concerning thing is why I can not instantiate my, so called, TicketEntities(ObjectContext) object from other projects? when I catch following exception: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. I found out it's brake at: public partial class TicketEntities : global::System.Data.Objects.ObjectContext { public TicketEntities() : base("name=TicketEntities", "TicketEntities") { this.OnContextCreated(); } with exception: Unable to load the specified metadata resource. Just to remind you everthing works fine from orginal project.

  • What's the Best Practice for Firing Manual OnClick Events?

    - by Tyler Murry
    Hey guys, I've got an XNA project that will be drawing several objects on the screen. I would like the user to be able to interact with those items. So I'm trying to build a method that checks to see which object the mouse is over, out of those which is the top most, and then fire an OnClick event for that object. Checking for the things above is not the problem, but where to actually put that logic is most of the issue. My initial feeling is that the checking should be handled by a master object - since it doesn't make sense for an object, who ideally knows only about itself, to determine information about the other objects. However, calling OnClick events remotely from the master object seems to be counter-intuitive as well. What's the best practice in this situation? Thanks, Tyler

  • Flowcharting tool/add-in for Visual Studio

    - by Rajah
    A 2 part question: Are flow-charts, as tool to analyze source-code, no longer considered useful? The reason I ask this question is that if you Google for source-code to flowchart tools for Visual Studio, there are no relevant results. Also, Microsoft does not seem to have a tool for this purpose. Are people just not using flowcharts that much any more? (I find them to be a great way to document complex logic in my code). Are there any VS tools that can take .Net (C#, VB.Net) code and convert it to a flowchart? (The only tool that I found is Aviosto's Visustin, which does not provide VS integration). Any other tools that you can recommend for this purpose?

  • best way to reference business objects from presentation layer..?

    - by Vytas999
    I want to develop an enterprise app that includes a WindowsForms presentation layer, middle-tier components for business logic and data access, and a MsSQL Server database. Middle-tier components should contain some business objects and will be called from presentation layer using .NET Remoting. Whitch is the best way (and why) to reference these business objects from presentation layer? a) Create class library project, implementing business objects. Reference this project from presentation layer and middle-tier layer. b) Create interface library project defining business objects. Create class library project implementing interfaces. Reference class library project from middle-tier layer. Reference interface library project from presentation layer. c) Create separate class library projects for middle-tier and presentation layer. Reference corresponding project from presentation layer.

  • Testing across multiple sessions in merb using webrat

    - by m7d
    I want to test across multiple sessions using webrat in merb. Apparently, this is fairly easy to accomodate in Rails via: http://erikonrails.snowedin.net/?p=159. Following the same logic, I am trying to do something that follows that pattern for merb and webrat. Here is an attempt (which does not work because MerbAdapter does not respond to visit and other webrat session methods; I don't want to take too much more time with this so I have stopped here for now): # defined in test.rb environment file module Merb #:nodoc: module Test #:nodoc: module RequestHelper #:nodoc: def in_a_separate_session old = @_webrat_session.response.clone @_webrat_session = Webrat::MerbAdapter.new yield @_webrat_session.response = old end end end end I tried a few other ideas, but obviously I am missing something. Anyone else know how this would be done in merb? I think I could specify a cookie jar using the request mock, but I prefer to do this with webrat.

  • Delayed "rendering" of WPF/Silverlight Dependency Properties?

    - by Aardvark
    Is there a way to know the first time a Dependency Property is accessed through XAML binding so I can actually "render" the value of the property when needed? I have an object (class derived from Control) that has several PointCollection Dependency Properties that may contain 100's or 1000's of points. Each property may arrange the points differently for use in different types shapes (Polyline, Polygon, etc - its more complicated then this, but you get the idea). Via a Template different XAML objects use TemplateBinding to access these properties. Since my object uses a Template I never know what XAML shapes may be in use for my object - so I never know what Properties they may or may not bind to. I'd like to only fill-in these PointCollections when they are actually needed. Normally in .NET I'd but some logic in the Property's getter, but these are bypassed by XAML data binding. I need a WPF AND Silverlight compatible solution. I'd love a solution that avoids any additional complexities for the users of my object.

  • What way to use the CGContext to draw is suitable?

    - by Tattat
    I know that the CGContext cannot call it to draw directly, and it needs to fill the drawing logic in the drawInContext, and call the CGContext to draw using "setNeedsDisplay", so, I designed a cmd to execute, but it cause some problems... like this : http://stackoverflow.com/questions/2617827/why-i-cant-draw-in-a-loop-using-uiview-in-iphone I think the CGContext is very different from my previous programming experience....(I used HTML5 canvas, that allow me add more details, after I draw, so do the Java Swing) Actually, I want to know what is the suitable to implement these kind of thing in Apples' programmer mind.

  • Calling CONTENT_SCRIPT JS From BROWSER_ACTION Popup HTML

    - by Aristotle
    I'm working on a Google Chrome Extension and would like to get an HTML from within my popup HTML to call functions within my loaded javascript file. My manifest follows: { "name": "Extension", "version": "1.0", "description": "Extension", "browser_action": { "default_icon": "icon.png", "default_title": "Ext", "popup": "popup.html" }, "content_scripts": [{ "matches": ["http://*/*"], "css": ["ext.css"], "js": ["jquery.js","scripts.js"] }], "permissions": [ "http://*/*" ] } As you can see I'm loading in a local copy of jQuery, along with another javascript file for my own personal logic. My popup document looks like this: <select id="values"> <option>Foo</option> <option>Bar</option> </select> And the contents of my scripts.js file follow: $(function(){ $("#values").change(function(){ alert("Foo"); }); }); This isn't doing what I expect though - alerting "Foo" anytime I change a value in my popup HTML. How can I get these two files to communicate with eachother? Or can they at all?

  • jquery validate plugin: add a custom method

    - by pixeline
    I need some guidance on how to add a validation method to the jquery validate plugin. I've gathered that i need to use the plugin's addMethod() function, but how exactly to have it do what i need... Here i am! My form 's first question is a radio input choice. Each radio input, if selected, shows a sub-question of several checkboxes. What i would like my validation to do is: - make sure one radio input is selected - make sure at least one checkbox pertaining to the radio input is selected. Basically, out of the validate plugin's own logic, i would count the selector's length, and if there isn't any, return the error message. Something like this: var weekSelected = ($('input.seasonSelector:checked input.weekSelector:checked',form).length > 0); if(!weekSelected){ return 'Please select a week inside that season'; } How to turn that into a validate plugin method ?

  • Polynomial division overloading operator (solved)

    - by Vlad
    Ok. here's the operations i successfully code so far thank's to your help: Adittion: polinom operator+(const polinom& P) const { polinom Result; constIter i = poly.begin(), j = P.poly.begin(); while (i != poly.end() && j != P.poly.end()) { //logic while both iterators are valid if (i->pow > j->pow) { //if the current term's degree of the first polynomial is bigger Result.insert(i->coef, i->pow); i++; } else if (j->pow > i->pow) { // if the other polynomial's term degree is bigger Result.insert(j->coef, j->pow); j++; } else { // if both are equal Result.insert(i->coef + j->coef, i->pow); i++; j++; } } //handle the remaining items in each list //note: at least one will be equal to end(), but that loop will simply be skipped while (i != poly.end()) { Result.insert(i->coef, i->pow); ++i; } while (j != P.poly.end()) { Result.insert(j->coef, j->pow); ++j; } return Result; } Subtraction: polinom operator-(const polinom& P) const //fixed prototype re. const-correctness { polinom Result; constIter i = poly.begin(), j = P.poly.begin(); while (i != poly.end() && j != P.poly.end()) { //logic while both iterators are valid if (i->pow > j->pow) { //if the current term's degree of the first polynomial is bigger Result.insert(-(i->coef), i->pow); i++; } else if (j->pow > i->pow) { // if the other polynomial's term degree is bigger Result.insert(-(j->coef), j->pow); j++; } else { // if both are equal Result.insert(i->coef - j->coef, i->pow); i++; j++; } } //handle the remaining items in each list //note: at least one will be equal to end(), but that loop will simply be skipped while (i != poly.end()) { Result.insert(i->coef, i->pow); ++i; } while (j != P.poly.end()) { Result.insert(j->coef, j->pow); ++j; } return Result; } Multiplication: polinom operator*(const polinom& P) const { polinom Result; constIter i, j, lastItem = Result.poly.end(); Iter it1, it2, first, last; int nr_matches; for (i = poly.begin() ; i != poly.end(); i++) { for (j = P.poly.begin(); j != P.poly.end(); j++) Result.insert(i->coef * j->coef, i->pow + j->pow); } Result.poly.sort(SortDescending()); lastItem--; while (true) { nr_matches = 0; for (it1 = Result.poly.begin(); it1 != lastItem; it1++) { first = it1; last = it1; first++; for (it2 = first; it2 != Result.poly.end(); it2++) { if (it2->pow == it1->pow) { it1->coef += it2->coef; nr_matches++; } } nr_matches++; do { last++; nr_matches--; } while (nr_matches != 0); Result.poly.erase(first, last); } if (nr_matches == 0) break; } return Result; } Division(Edited): polinom operator/(const polinom& P) const { polinom Result, temp2; polinom temp = *this; Iter i = temp.poly.begin(); constIter j = P.poly.begin(); int resultSize = 0; if (temp.poly.size() < 2) { if (i->pow >= j->pow) { Result.insert(i->coef / j->coef, i->pow - j->pow); temp = temp - Result * P; } else { Result.insert(0, 0); } } else { while (true) { if (i->pow >= j->pow) { Result.insert(i->coef / j->coef, i->pow - j->pow); if (Result.poly.size() < 2) temp2 = Result; else { temp2 = Result; resultSize = Result.poly.size(); for (int k = 1 ; k != resultSize; k++) temp2.poly.pop_front(); } temp = temp - temp2 * P; } else break; } } return Result; } }; The first three are working correctly but division doesn't as it seems the program is in a infinite loop. Final Update After listening to Dave, I finally made it by overloading both / and & to return the quotient and the remainder so thanks a lot everyone for your help and especially you Dave for your great idea! P.S. If anyone wants for me to post these 2 overloaded operator please ask it by commenting on my post (and maybe give a vote up for everyone involved).

  • External XMPP component - Anyone know a Tutorial or Open Source Example please?

    - by gav
    Hi All, I want to run an XMPP server (Openfire) and register an external component to handle the messages it will recieve (using the Whack library). The external component will run my game logic and I will be using XMPP to send player moves to the server and status updates in the other direction. The bonus with XMPP is that we get built in chat for free. The trouble is, although Ignite look fairly established, I can't find a tutorial on how to write, register and debug an External XMPP component written with Whack, there are very few in general for that matter. I am not invested in either the server implementation or the External Component library, java is just my language of choice. If I was to move to Erlang or Scala or something it would have to be a very simple in that language. A single tutorial or example would go a long way here, I just need an basic External XMPP component pretty please! Kind regards, Gavin

  • Send parameters in order in HTTPService

    - by Suraj Chandran
    I am trying to work with a simple HTTPService. The problem is that my webservice is conscious of the order of arguments it gets. I will tell the problem with an example: var service:HTTPService = new HTTPService(); var params:Object = new Object(); params.rows = 0; params.facet = "true"; service.send(params); Note that in the above code I have mentioned the parameter rows before facet, but the url I recieve is facet=true&rows=0. So I recieve the argument rows before facet and hence my webservice does not work. I figured out that the contents of array is always sent in alphabetical order, which I dont want. Is there any way I can achieve explict ordering of parameters sent? Note that I am not in power of changing the logic of webservice(its basically a RPC service supporting both desktop and web client). Thanks.

  • "Authorize" attribute and 403 error page

    - by zerkms
    [Authorize] property is nice and handy MS invention, and I hope it can solve the issues I have now To be more specific: When current client isn't authenticated - [Authorize] redirects from secured action to logon page and after logon was successfull - brings user back, this is good. But when current cilent already authenticated but not authorized to run specific action - all I need is to just display my general 403 page. Is it possible without moving authorization logic within controller's body? UPD: The behavior I need in should be semantically equals to this sketch: public ActionResult DoWork() { if (!NotAuthorized()) { return RedirectToAction("403"); } return View(); } so - there should no any redirect and url should be stay the same, but contents of the page should be replaced with 403-page

  • Hex representation of Euro Symbol €

    - by Rahul
    Hi I was using XVI32 (Hex Editor) to get the hex representation of the Euro symbol and it gives me the value as 80. Another site: http://www.string-functions.com/string-hex.aspx does the same. I am not able to understand why the hex representation is 80 instead of 0x20AC. This 0X80 gives 128 in decimal and if I use Alt+0128 it actually produces the Euro symbol. Could somebody throw some light on what could be the logic behind this conversion from string to hex conversion ? Thanks

  • XStream <-> Alternative binary formats (e.g. protocol buffers)

    - by sehugg
    We currently use XStream for encoding our web service inputs/outputs in XML. However we are considering switching to a binary format with code generator for multiple languages (protobuf, Thrift, Hessian, etc) to make supporting new clients easier and less reliant on hand-coding (also to better support our message formats which include binary data). However most of our objects on the server are POJOs with XStream handling the serialization via reflection and annotations, and most of these libraries assume they will be generating the POJOs themselves. I can think of a few ways to interface an alternative library: Write an XStream marshaler for the target format. Write custom code to marshal the POJOs to/from the classes generated by the alternative library. Subclass the generated classes to implement the POJO logic. May require some rewriting. (Also did I mention we want to use Terracotta?) Use another library that supports both reflection (like XStream) and code generation. However I'm not sure which serialization library would be best suited to the above techniques.

  • How to get MAX value of a version-number (varchar) column in T-SQL

    - by Ogre Psalm33
    I have a table defined like this: Column: Version Message Type: varchar(20) varchar(100) ---------------------------------- Row 1: 2.2.6 Message 1 Row 2: 2.2.7 Message 2 Row 3: 2.2.12 Message 3 Row 4: 2.3.9 Message 4 Row 5: 2.3.15 Message 5 I want to write a T-Sql query that will get message for the MAX version number, where the "Version" column represents a software version number. I.e., 2.2.12 is greater than 2.2.7, and 2.3.15 is greater than 2.3.9, etc. Unfortunately, I can't think of an easy way to do that without using CHARINDEX or some complicated other split-like logic. Running this query: SELECT MAX(Version) FROM my_table will yield the erroneous result: 2.3.9 When it should really be 2.3.15. Any bright ideas that don't get too complex?

  • A PHP design pattern for the model part [PHP Zend Framework]

    - by Matthieu
    I have a PHP MVC application using Zend Framework. As presented in the quickstart, I use 3 layers for the model part : Model (business logic) Data mapper Table data gateway (or data access object, i.e. one class per SQL table) The model is UML designed and totally independent of the DB. My problem is : I can't have multiple instances of the same "instance/record". For example : if I get, for example, the user "Chuck Norris" with id=5, this will create a new model instance wich members will be filled by the data mapper (the data mapper query the table data gateway that query the DB). Then, if I change the name to "Duck Norras", don't save it in DB right away, and re-load the same user in another variable, I have "synchronisation" problems... (different instances for the same "record") Right now, I use the Multiton pattern : like Singleton, but multiple instances indexed by a key (wich is the user ID in our example). But this is complicating my developpement a lot, and my testings too. How to do it right ?
