  • N-tier architecture and unit tests (using Java)

    - by Alexandre FILLATRE
    Hi there, I'd like to have your expert explanations about an architectural question. Imagine a Spring MVC webapp, with validation API (JSR 303). So for a request, I have a controller that handles the request, then passes it to the service layer, which passes to the DAO one. Here's my question. At which layer should the validation occur, and how ? My though is that the controller has to handle basic validation (are mandatory fields empty ? Is the field length ok ? etc.). Then the service layer can do some tricker stuff, that involve other objets. The DAO does no validation at all. BUT, if I want to implement some unit testing (i.e. test layers below service, not the controllers), I'll end up with unexpected behavior because some validations should have been done in the Controller layer. As we don't use it for unit testing, there is a problem. What is the best way to deal with this ? I know there is no universal answer, but your personal experience is very welcomed. Thanks a lot. Regards.

  • Why will network manager not allow me save my VPN settings?

    - by Solignis
    I am trying to configure am OpenVPN client on my laptop. I am running Ubuntu 11.10 64-bit. When I open network manager and import the VPN settings from the premade config folder everything takes. The problem is when I try to save the settings, the save button at the bottom of the network manager applet is greyed out. Further more when I hover over the button it says Authenticate to save this connection for all users of this machine. The problem is I did not check the box Available to all users it was already checked and it is also greyed out and won't let me manipulate it. What is going on? Is this a bug or is there something I am missing? Any help would be wonderful.

  • Slow file copying/network browsing in Windows 7

    - by tomp
    The file copying on local discs and network shares, and browsing shared folders is much slower on the Windows 7 than it was on Windows XP. I'm sure everyone encountered this problem, I personally have seen it on many different computers. What would you recommend to speed up these operations?

  • ASP.NET plug-in architecture, settings problem

    - by Xaqron
    I want to divide business layer (BLL) of an asp.net application into multiple components. Each component is a .NET class library which is compiled as a standalone DLL. These components should have their own configuration files. For example "MyNameSpace.Users.dll" contains classes about users of the website and there's a password policy to check if password length is at least x characters. When webmaster edits the config file of this DLL and set x to y then component (DLL) should use new value (y) in the future and enforce passwords to be at least y characters. I want each component as a single project and compile them separaely (and not to put all projects in a solution in Visual Studio), and put the DLLs of these libraries into the "Bin" folder of my ASP.NET application. Is it possible ? Where should I put these config files ?

  • Network connection thou a wall

    - by BCS
    I have a place where I want to set up a network connection thou a normal residential wall where I can't cut any holes. I don't want to just set up a wireless system. Does anyone make a device that you place on either side of a wall to hook up a connection? Preferably something that can do 100Mb full duplex and can't be eavesdropped on with common hardware?

  • need advice on Zend framework Application architecture, or say approach dealing with modules

    - by simple
    Let me start with the things that I did and how am I using some things to get results I have set up modular structure as: application/ /configs /layouts /models /modules /users /profile /frontend /backend /controllers /views .... I write a plugin that does addes changes with FrontController-setModuleControllerDirectoryName() FrontController-addModuleDirectory() and It is all good I have a changed all the directories according weather admin page is requested in the url or not (it is some thing like /admin/some/some) Let's say I have a single layout for anything that is related to Profile viewing , in this case the "Profile" module. The Profile layout is divided into three parts In the layout I was pulling out the Profile/PhotoController 's index action with a action() $this->action('index', 'photo', 'profile'); Then I have faced few issues 1. Can get passed Params inside the Photo Controller when calling ( profile/profile/index); 2. found out that helper Action() is evil cause it starts another dispatching loop =) --- and now I am thinking that my approach on plugging in controllers modules into layout also evil =). anyhow how Should I deal with plugging in some controllers (another module controllers) into the layout ?

  • How to run open dns on a network

    - by user37652
    I need to be enlightened in this topic. First, is it possible to run open dns on a network so that you won't have to install the open dns updater to update the ip address of those machines with dynamic ip address. Second, how do I set it up. Can I set it up on the router?

  • Best architecture for accessing secondary database

    - by fearofawhackplanet
    I'm currently developing an app which will use a Linq to SQL (or possibly EF) data access layer. We already have a database which holds all our Contacts information, but there is currently no API around this. I need to interact with this DB from the new app to retrieve contact details. I can think of two ways I could do this - 1) Develop a suite of web services against the contacts database 2) Write a Linq to SQL (or EF) DAL and API against the contacts database I will probably be developing several further apps in the future which will also need access to the Contacts data. Which would generally be the prefered method? What are the points I need to consider? Am I even asking a sensible question, or am I missing something obvious?

  • Software Architecture: Unit of Work design pattern discussion

    - by santiagobasulto
    Hey everybody. According Martin Fowler's Unit of Work description: "Maintains a list of objects that are affected by a business transaction and coordinates the writing out of changes and resolution of concurrency problems." Avoiding very small calls to the database, which ends up being very slow I'm wondering. If we just delimit it to database transaction management, won't prepare statements help with this?

  • "conveyor belt" cache architecture

    - by Andrew Matthews
    I'm producing an application with a few peculiar internal communication characteristics that make the usual suspects for data storage and transport (Qs and RDBMSs) ill-fitted. I'm wondering whether there is a product out there that matches the following characteristics: all data put into it is peristent all reads are delivered out of memory data is universally available data lives where it is most needed data is versioned (nice to have) updates are transactional (I'd like ACID characteristics) data is potentially replicated, but always in sync works on windows is based on or has bindings for .NET is really fast is really robust is redundant is scalable I'm looking at things like Microsoft codename "Velocity", but I am not sure whether it fits all of the above characteristics. Likewise, Memcached is not a perfect fit either. The current version of this app opts for an RDBMS with a signaling system for inter-system sync, but latency is too high and versioning of the DB is a pain. I need all the robustness, but with none of the trade-offs.

  • Asp.Net MVC and Entity Framework Architecture

    - by Pino
    Hi, I'm working on a fairly large project at the moment and am currently in the planning stages. I've done a lot of reading into the various patterns suggested for development, somthing that has split the team at the moment is when using Entity Framework should the classes be passed through the applciation layers so that a view accepts an Entity Framework class or should these classes be mapped to BLL Classes and if so at which point (Controller or Library) should this be done? I'm interested in hearing some positives and negitives for each solutions.

  • GUI system architecture?

    - by topright
    I'm designing GUI (graphical user interface) system for a game engine (C++). Idea is to create a heirarchy of GUI controllers like Focusable, Hoverable, Dragable etc. Every GUI component can attach multiple controllers, they modify component's behaviour. I think it gives flexible system and protects from code duplication. Different instances of the same GUI class can have different complex behaviours (may be, even change it dynamically), so this approach looks practical. The other choice is to add focused, hovered, dragged etc. flags in the base GUI component class. It looks like overhead and not that flexible. Another solution is to use Decorator pattern and wrap objects with FocusDecorator, HoverDecorator etc. Maintaining such system looks a bit harder. Question: What are pitfalls in my solution? May be you have seen a better approaches in GUI systems? What are the best ways of implementing such flexible complex system?

  • Secure database connection. DAL .net architecture best practice

    - by Andrew Florko
    We have several applications that are installed in several departments that interact with database via Intranet. Users tend to use weak passwords or store login/password written on a shits of paper where everybody can see them. I'm worried about login/password leakage & want to minimize consequences. Minimizing database-server attack surface by hiding database-server from Intranet access would be a great idea also. I'm thinking about intermediary data access service method-based security. It seems more flexible than table-based or connection-based database-server one. This approach also allows to hide database-server from public Intranet. What kind of .net technologies and best practices would you suggest? Thank in you in advance!

  • Looking for network monitoring software for Win7 x64 (similar to the one included with Sunbelt perso

    - by rep_movsd
    I've upgraded from Windows XP to Windows 7 (64bit) and I found that the very convenient Sunbelt Kerio Personal Firewall will not work on this version. I hear the Windows 7 firewall is good enough(even though it never prompts for outbound connections) but Kerio had a nice network monitor feature which showed all applications with inbound and outbound connections and the current speed and bytes transferred for each one. Is there any software out there that can give me similar monitoring as what Kerio does? TCPView is almost as good, but doesnt show transfer statistics.

  • Modular enterprise architecture using MVC and Orchard CMS

    - by MrJD
    I'm making a large scale MVC application using Orchard. And I'm going to be separating my logic into modules. I'm also trying to heavily decouple the application for maximum extensibility and testability. I have a rudimentary understanding of IoC, Repository Pattern, Unit of Work pattern and Service Layer pattern. I've made myself a diagram. I'm wondering if it is correct and if there is anything I have missed regarding an extensible application. Note that each module is a separate project.

  • 2Wire USB Network Adapter Not Working With Windows 7

    - by Andrew
    I installed Windows 7 on a separate drive, and everything works fine, but I can't get the above network adapter to work properly. It's displayed in Device Manager as a USB device, and I have the driver that makes it function in Vista, but when I run the Driver Wizard and direct it to directory where I have the Vista driver, it almost immediately says "Can't install driver." Is there any work around to this?

    I've got some application on my Windows XP machine that is generating an HTTP request to aaronsw.com every half hour. We've trapped the packets in wireshark, but wireshark doesn't tell what application generated the packets. Is there any utility that looks at network traffic AND tells what executable produced the traffic?

  • jquery javascript module architecture on a website

    - by stephan
    I want to write a module on one html site - I will never leave the site I think about two possible concurrent basic approaches: We go into the module by use only a specific function (with specific params - everything which will happen, happen there - logic, exception handling etc) We go in by using one handler-fct, which manages some kind of action & a dataArray (depending on the action also fcts will be called - but not directly maybe for exception handling) So what you prefer?!

  • Roadmap for Architecture

    - by NoProblemBabe
    Ok, I am a developer for 6 years now and I came from a hater to an enthusiast about technology. I am a senior developer, almost all focused in web applications, asp.net, quite experienced and very, very focused in develop myself. I come to a crossroads in my area, I want to become an Architect, not an analyst or a project manager. I like to get my hands dirty, to actually do things, and I, well,... have to admit it, that I am a little lost about what I should've already known, and what i should be studying, in order to enter in that field. So here comes the question: What an Architect should be proficient in?
