  • How to override the behavior of Spring @Autowired

    - by Mark
    Hi a little background: I am Using Spring 2.5, and specifically spring IOC and annotations. I am using @Autowired in my code (the Autowiring is done by type) and use @Component for exposing Classes to the Automatic wiring. The situation described bellow arose while i tried to test my code. now to the problem: Note: i use a different Spring Context for the Test environment. I have a class FOO which is @Autowired but in the test context i want to use a different class of the same type MockFoo (extends FOO) The Spring Setup of course fails do so automatically due to multiple options for the Dependency Injection of the FOO class (both FOO and MockFOO comply to the Type check) I am looking for a way to inject the test bean instead of the original bean. I expected Spring to allow using the Context configurion file to override a bean injection or to order Spring not to autowire a specific bean BUT All these option seem to exists only for the beans which were originally defined in the Spring Context Configuration file

    - by vinay123
    In my code I am using JSF - Front end , EJB-Middile Tier and JPA connect to DB.Calling the EJB using the Webservices.Using MySQL as DAtabase. I have created the Voter table in which I need to insert the record. I ma passing the values from the JSF to EJB, it is working.I have created JPA controller class (which automatcally generates the persistence code based on the data base classes) Ex: getting the entity manager etc., em = getEntityManager(); em.getTransaction().begin(); em.persist(voter); em.getTransaction().commit(); I have created the named query also: @NamedQuery(name = "Voter.insertRecord", query = "INSERT INTO Voter v values v.voterID = :voterID,v.password = :password,v.partSSN = :partSSN,v.address = :address, v.zipCode = :zipCode,v.ssn = :ssn, v.vFirstName = :vFirstName,v.vLastName = :vLastName,v.dob = :dob"),But still not able to insert the record? Can anyone help me in inserting the record into the Data base through JPA.(Persistence object)?

  • Fluent NHibernate MappingException : could not instantiate id generator

    - by Mark Simpson
    I'm pottering around with Fluent NHibernate to try and get a simple app up and running. I'm running through this Fluent NHibernate Tutorial. Everything seems to be going fine and I've created the required classes etc. and it all builds, but when I run the test, I get an exception. Someone in the comments section of the tutorial has the same problem, but I can't find any good information on what's causing it. Any help appreciated. It's probably something trivial. Exception details: FluentNHTest.Tests.Mappings.CustomerMappingTests.ValidateMappings: FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. ---- FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. ---- NHibernate.MappingException : could not instantiate id generator ---- System.FormatException : Input string was not in a correct format.

  • How to include simple collections in ConfigurationSection

    - by mikemanne
    Is there a way for me to include a simple array of strings, or List<string> on my custom subclass of ConfigurationSection? (Or an array or generic list of simple data objects, for that matter?) I'm becoming familiar with the new (and VERY verbose) ConfigurationSection, ConfigurationElement, and ConfigurationElementCollection classes, but I'm by no means an expert yet. It seems like ConfigurationSection should handle simple collections/lists on its own, without me having to create a custom ConfigurationElementCollection subclass for each and every one. But I haven't found any reference to this ability online.

  • Is there a way to know in VB.NET if a handler has been registered for an event?

    - by Seth Spearman
    In C# I can test for this... public event EventHandler Trigger; protected void OnTrigger(EventArgs e) { if (Trigger != null) Trigger(this, e); } Is there a way to do this in VB.NET? Test for null I mean? MORE INFO I forgot to mention. I have classes written in C# but I am writing my unit tests in VB.NET. I am trying this in the unit test... If myObject.Trigger IsNot Nothing Then 'do something End If This is causing a compile time error which says ... "Public Event Trigger is an Event and cannot be called directly. Use the RaiseEvent statement to raise an event." Seth

  • boost::dynamic_pointer_cast with const pointer not working ?

    - by ereOn
    Hi, Let's say I have two classes, A and B, where B is a child class of A. I also have the following function: void foo(boost::shared_ptr<const A> a) { boost::shared_ptr<const B> b = boost::dynamic_pointer_cast<const B>(a); // Error ! } Compilation with gcc gives me the following errors: C:\Boost\include/boost/smart_ptr/shared_ptr.hpp: In constructor 'boost::shared_ptr< <template-parameter-1-1> >::shared_ptr(const boost::shared_ptr<Y>&, boost::detail::dynamic_cast_tag) [with Y = const A, T = const B]': C:\Boost\include/boost/smart_ptr/shared_ptr.hpp:522: instantiated from 'boost::shared_ptr<X> boost::dynamic_pointer_cast(const boost::shared_ptr<U>&) [with T = const B, U = const A]' src\a.cpp:10: instantiated from here C:\Boost\include/boost/smart_ptr/shared_ptr.hpp:259: error: cannot dynamic_cast 'r->boost::shared_ptr<const A>::px' (of type 'const class A* const') to type 'const class B*' (source type is not polymorphic) What could possibly be wrong ? Thank you.

  • Sugar CRM integration with Java - How to add relationship

    - by Arun P Johny
    Hi, I'm trying to integrate Sugar CRM with one of my projects. I'm using Apache Axis as my SOAP client. I've created the Sugar CRM client Stub classes using Apache Axis. I'm able to login and add Leads, Opportunities, Accounts and Contacts. But I'm unable to add a relation ship between my Account and Opportunity. I've found following method in the SugarsoapPortType port.set_relationship(session, module_name, module_id, link_field_name, related_ids, name_value_list, delete) but I cannot understand the different parameters required by this method. Most of the online documents suggests a simple way as given below $result = $client->call('set_relationship',array("session"=>$session _id,array("module1"=>"Emails","module1_id"=>"<module1_id>","module2"=>"Accounts","module2_id"=> "<module2_id>"))); how can I achieve this using Java Thanks

  • Intercept web requests from a WebView Flash plugin

    - by starkos
    I've got a desktop browser app which uses a WebView to host a Flash plugin. The Flash plugin makes regular requests to an external website for new data, which it then draws as fancy graphics. I'd like to intercept these web requests and get at the data (so I can display it via Growl, instead of keeping a desktop window around). But best I can tell, requests made by Flash don't get picked up by the normal WebView delegates. Is there another place I can set a hook? I tried installing a custom NSURLCache via [NSURLCache setSharedURLCache] but that never got called. I also tried method swizzling a few of the other classes (like NSCachedURLResponse) but couldn't find a way in. Any ideas? Many thanks!

  • jQuery Resizable() UI Problem

    - by OneNerd
    In general, resizable() works fine. Here is where I am getting into an issue. I have a div that contains some resizable items that work fine (resizable() applied to them at some point). user can save items for later view (the innerHTML of the div gets saved into a JavaScript array, then div gets cleared so they can do something else) When items get placed back onto div (from array) -- I do a $('#divname').append(arrayname[i]); -- items are no longer resizable (although visually they have the resizable classes/handle on them) Here is what I have tried so far (none of which have worked): After append() line, I re-initialize the resizable -- $('#items').resizable(); After append() line, remove then re-add resizable -- $('#items').resizable('destroy').resizable(); Any help is appreciated - thanks.

  • MVVM (ICommand) in Silverlight

    - by Andrey Khataev
    Hello! Please, don't judge strictly if this question was discussed previously or indirectly answered in huge nearby prism and mvvm blogs. In WPF implementation of RelayCommand or DelegateCommand classes there is a such eventhandler /// <summary> /// Occurs whenever the state of the application changes such that the result of a call to <see cref="CanExecute"/> may return a different value. /// </summary> public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } but in SL subset of namespaces there are no CommandManager class. And this is where I'm stuck. I haven't yet found an workaround for this in MVVM adoptation for SL (PRISM is so complex for me yet). Different simple HelloWorldMVVM apps don't deal with at all. Thanks in advance and sorry for my English -)

  • Iphone -- init method of an abstract class

    - by William Jockusch
    I want to create classes Car, Vehicle, and Airplane with the following properties: Car and Airplane are both subclasses of Vehicle. Car and Airplane both have an initWithString method. The acceptable input strings for Car's and Airplane's initWithString methods do not overlap. Vehicle is "almost abstract", in the sense that any initialized instance should be either a Car or an Airplane. It is possible to pass a string into Vehicle and get back an instance of Car, an instance of Airplane, or nil, depending on the input string. Any particular design pattern I should prefer? In particular for Vehicle's initWithString and/or newVehicleWithString methods.

  • Is removing unused functionality a bad thing?

    - by Andrew Grimm
    Is it possible for YAGNI to apply in the past tense? You created some functionality, it was used a little bit a while ago, but you aren't using it any more, and you don't want to maintain it, so you'd rather delete it. Is getting rid of unused or rarely-used functionality neccessarily a bad thing? Background: I use source control, so if I need the functionality again, I can get it. I'm the only user of my software (I'm a bioinformatician analyzing a data set). One scenario where I came across this was that I was using inheritance, with a parent class, and two child classes. One was handling files generated by 454 sequencing (next-generation sequencing), and the other was handling files generated by Sanger sequencing (previous-generation sequencing). I was actively maintaining the latter, but not the former. Maybe my mistake was using inheritance rather than composition, but that's a slightly different story.

  • Embedded web server and gui framework for .NET applications

    - by Toad
    Hi, I'm looking for a framework which allows me to manage my application through a webbased GUI (using an embedded webserver) instead of winforms. Something like this: http://www.webtoolkit.eu/wt but then for .NET In my code I should be able to instantiate classes (like buttons, forms etc), and when a user browses to a given port, the app should render it as javascript/ajax etc etc. preferably, when buttons are pushed, a notification in my code should be called. this is a less specific question than another one I posted about extjs. I hope this will attract more viewers since it is more generic Thanks. Update: cassini like solutions don't fit the bill. Since the webbrowser is embedded in my application, there is no need for ASP.NET server side scripts. I would rather have the framework, call functions inside my application when things happen on the page. onButtonClicked() for instance.

    Can I do it only with the lti-Civil classes or I need FMJ or JMF ? do I use the actual Stream or set of captured Images from CaptureObserver? Thanks. captureStream = system.openCaptureDeviceStream(info.getDeviceID()); captureStream.setObserver(new CaptureObserver(){ public void onError(CaptureStream arg0, CaptureException arg1) { } public void onNewImage(CaptureStream streamSource, Image image) { try { imageFrame.setImage(AWTImageConverter.toBufferedImage(image)); bufferedImage = AWTImageConverter.toBufferedImage(image); } catch (Throwable t) { t.printStackTrace(); } } }); captureStream.start();

  • What is the motivation behind "Use Extension Methods Sparingly?"

    - by Robert Harvey
    I find them a very natural way to extend existing classes, especially when you just need to "spot-weld" some functionality onto an existing class. Microsoft says, "In general, we recommend that you implement extension methods sparingly and only when you have to." And yet extension methods form the foundation of Linq; in fact, Linq was the reason extension methods were created. Are there specific design criteria where using extension methods are perferred over inheritance or composition? Under what criteria are they discouraged?

  • VS 2010 Class Diagram Error "The type cannot be edited..."

    - by Eric J.
    A few of the classes on a VS 2010 class diagram are displayed with a red title. The Class Details window shows all of the methods, properties, fields and correctly shows no events. However, there's an entry under each of methods, properties, fields and events that states where the name should be: "The type cannot be edited because the source code file contains an error." However, the source file builds with no errors or warnings. Anyone seen this? Any idea how to fix it?

  • ASP.NET MVC: What's the difference in concept between Service and Repository

    - by Richard77
    Hello, The question I'm asking is kind of subjective. I've seen twice, while exercising with real projects such as StoreFront, both Repository and Services. Sometimes they can just be folders or projects attached to the solution. But they contain classes and interfaces. So, I'd like to know what goes to the repository and what goes to the services. So far, I was familiar with repositories (we put methods and properties in the repository to reduce the complexity in the controller). How about the services? So, ASP.NET MVC: What's the difference in concept between Service and Repository? (Maybe none) My question is Kind of subjective, but I'd like to make sure that I'm not missing anything. Thanks for helping

  • Ordering the calling of asynchronous methods in c#

    - by Peter Kelly
    Hi, Say I have 4 classes ControllerClass MethodClass1 MethodClass2 MethodClass3 and each MethodClass has an asynchronous method DoStuff() and each has a CompletedEvent. The ControllerClass is responsible for invoking the 3 asynchronous methods on the 3 MethodClasses in a particular order. So ControllerClass invokes MethodClass1.DoStuff() and subscribes to MethodClass1.CompletedEvent. When that event is fired, ControllerClass invokes MethodClass2.DoStuff() and subscribes to MethodClass2.CompletedEvent. When that event is fired, the ControllerClass invokes MethodClass3.DoStuff() Is there a best practice for a situation like this? Is this bad design? I believe it is because I am finding it hard to unit test (a sure sign) It is not easy to change the order I have an uneasy, code-smell feeling about it What are the alternatives in a situation like this?

  • Where and how to validate and map ViewModel?

    - by chobo
    Hi, I am trying to learn Domain Driven Design and recently read that lots of people advocate creating a ViewModels for your views that store all the values you want to display in a given view. My question is how should I do the form validation? should I create separate validation classes for each view, or group them together? I'm also confused on what this would look like in code. This is how I currently think validation and viewmodels fit in to the scheme of things: View (some user input) - Controller - FormValidation(of ViewModel) - (If valid map to ViewModel to Domain Model) - Domain Layer Service - Infrastructure Thanks! P.S. I use Asp.net MVC with C#

  • String Utility Library for Code Generation

    - by Adam Barney
    CodeSmith has a nice StringUtils class that can be used to change database object names to singular, plural, camel case, pascal case, etc... Very useful for creating data access layers in their code generation tool. I'm trying to port some CodeSmith templates to the T4 template files used by Visual Studio, and I'm trying to find a similar library to do these things. There must be one somewhere in T4, since that's what is used to produce the LINQ to SQL classes, and it does a nice job of pluralization / singularization. Does anyone know where this library exists, or if a free library with similar functionality exists somewhere? Thanks!

  • jQuery selector help - Can I generate a selector from clicking on an element?

    - by Kettenbach
    Hi All, I have jQuery, FireFox, Firebug, IE, and IE developer toolbar. When I am examing a page with either FireBug or IE Dev toolbar, I am able to click on an element and it shows me in the dom where the element is etc... Is there anyway to transform that selection into a valid jQuery selector? I know I can use ID, classes, and element relative to other elements etc... but what about when I am looking at some random table cell that doesn't have a class or id etc.. Can I generate a selector on the fly like that? I thought for sure there was. Any thoughts or ideas are always appreciated Thanks, ~ck in San Diego

  • What are good educational resources for setting up .Net Webservice on a DMZ connecting to SQL Server

    - by Brian
    We are going to begin implementing a web service that will be hosted on a DMZ server. This web server will post data to a SQL server and we're trying to determine the best methodology to handle this. Things that concern us are web service authentication, SOAP, and whether or not to store the database on the DMZ or the local network. This same scenario will apply to ASP.Net apps. Trust me, I've already searched the web, but as usual, the online resources I've found either talk about just authentication, or just about SOAP, or etc, but does not show or suggest how the entire system can work together. Can you give me a list of resources such as links that I've missed, books, classes, or etc that would help? Thank You.

  • ERD-CLASS design

    - by Mahesh
    Hello guyz,i am new to daatbase and class diagram.I just get scenarios from internet and try to develop ERD and Class Diagram for them.But the following scenario has caused me some problems, and i am not sure about my design. "Whenever an employee fills leave application form, the leave application should be appeared for approval to his/her team leader. Team Leader has the option to change the date of requested leave and to approve or reject the leave. Employee also has the option to change date of previously unapproved leaves or to cancel any of unapproved leave. In case of team leader, he can approve his own leaves. Management should be able to create categories of leaves like (Casual, Sick, Planned work, etc) and should be able to adjust the days allocated to each type of leave". I have identified these as entities for ERD 1) Employee(I think i dont need to make entity for Technical lead,since he is an employee) 2) LeaveHistory 3) LeaveCategory Plz correct me if the system need more classes or entities

  • Can i override an abstract method written in a parent class, with a different name in a child class?

    abstract class SettingSaver { public abstract void add(string Name, string Value); public abstract void remove(string SettingName); } class XMLSettings : SettingSaver { public override void add(string Name, string Value) { throw new NotImplementedException(); } public override void remove(string SettingName) { throw new NotImplementedException(); } } Is there anyway that I can change the name of the add function in XMLSettings class to addSetting but make sure it overrides the add function in the SettingSaver? I know it should be definitely overridden in derived classes but just want to know whether I can use a different name :) Thanx in advance :D
