  • Does business logic belong in the service layer?

    - by antony.trupe
    I've got a set of classes, namely, a data transfer object, a service implementation object, and a data access object. I currently have business logic in the service implementation object; it uses the dao to get data to populate the dto that is shipped back to the client/gui code. The issue is that I can't create a lightweight junit test of the service implementtion object(it's a servlet); I think the business logic should be elsewhere, but the only thing I can think of is putting business logic in the dao or in yet another layer that goes between the dao and the service implementation. Are there other options, or am I thinking about this the wrong way? It's a GWT/App Engine project.

    I can't figure out how to point unit tests at the queue config file.

  • Now with GWT2, what are the advantages over wicket and likewise?

    - by Antony Stubbs
    Apart from the argument of wicket's simplicity (that is, wicket is a simpler system IMHO) and GWT's responsiveness in the client (GWT's client side state and javascript - potentially complex client side code) and GWT's greater potential for scaling, what is the argument for using GWT over wicket? Personally I've done a lot of wicket development, but have only had a quick look at GWT a long time ago.

  • junit assert in thread throws exception

    - by antony.trupe
    What am I doing wrong that an exception is thrown instead of showing a failure, or should I not have assertions inside threads? @Test public void testComplex() throws InterruptedException { int loops = 10; for (int i = 0; i < loops; i++) { final int j = i; new Thread() { @Override public void run() { ApiProxy.setEnvironmentForCurrentThread(env);//ignore this new CounterFactory().getCounter("test").increment();//ignore this too int count2 = new CounterFactory().getCounter("test").getCount();//ignore assertEquals(j, count2);//here be exceptions thrown. this is line 75 } }.start(); } Thread.sleep(5 * 1000); assertEquals(loops, new CounterFactory().getCounter("test").getCount()); } StackTrace Exception in thread "Thread-26" junit.framework.AssertionFailedError: expected:<5> but was:<6> at junit.framework.Assert.fail(Assert.java:47) at junit.framework.Assert.failNotEquals(Assert.java:277) at junit.framework.Assert.assertEquals(Assert.java:64) at junit.framework.Assert.assertEquals(Assert.java:195) at junit.framework.Assert.assertEquals(Assert.java:201) at com.bitdual.server.dao.ShardedCounterTest$3.run(ShardedCounterTest.java:77)

  • Opera Mobile for Windows + Reported Screen Size

    - by Antony Scott
    I know this isn't a direct programming question, but's it's kinda relevant as I'm trying to get a good testing environment set up before I embark on my latest project. I'm trying to set up Opera Mobile for Windows to allow me to test a new website. The UserAgent I get is a fairly generic one, so my workaround is to tweak my mobile.browser file to have the correct screen width and height of the target device. Is it possible to add to the list of "fake" user agents that Opera Mobile for Windows can pretend to be? It currently supports S60, Android and Windows Mobile.

  • Resolving patch conflicts manually

    - by Antony Hatchkins
    I've downloaded a patch from some site and trying to apply it (twisted, python web framework). Several hunks failed. How do I automate manual patching process using vim? Details: I'm trying to automate the process of applying failed hunks. Many tiny changes, each about adding/removing 1-2 chars. Difficult to see. I Have to create two new temporary files and :diffthis them manually to see the difference. Yes, outside VCS. I can imagine a neat way to deal with it using git, but I would prefer to avoid creating git repo for that.

  • AJAX Autosave

    - by antony.trupe
    What's the best javascript library, or plugin or extension to a library, that has implemented autosaving functionality? The specific need is to be able to 'save' a data grid. Think gmail and Google Documents' autosave. I don't want to reinvent the wheel if its already been invented. I'm looking for an existing implementation of the magical autoSave() function. Auto-Saving:pushing to server code that saves to persistent storage, usually a DB. The server code framework is outside the scope of this question. Note that I'm not looking for an Ajax library, but a library/framework a level higher: interacts with the form itself. daemach introduced an implementation on top of jQuery @ http://ideamill.synaptrixgroup.com/?p=3. I'm not convinced it meets the lightweight and well engineered criteria though. Criteria stable, lightweight, well engineered saves onChange and/or onBlur saves no more frequently then a given number of milliseconds handles multiple updates happening at the same time doesn't save if no change has occurred since last save saves to different urls per input class Updates I've stabilized a solution. See my answer below for links.

  • Building Cocoa UIs for OS X with C# and Mono

    - by Antony Perkov
    Has anyone spent any time comparing the various Objective C bridges and associated Cocoa wrappers for Mono? I want to port an existing C# application to run on OS X. Ideally I'd run the application on Mono, and build a native Cocoa UI for it. I'm wondering which bridge would be the best choice. In case it's useful to anyone, here are some links to bridges I've found so far: CocoSharp - distributed with Mono on OS X - www.cocoa-sharp.com Monobjc - better documentation than the others (in my opinion) - www.mono-project.com/CocoaSharp and www.monobjc.net NObjective - (apparently) faster than the others - code.google.com/p/nobjective MObjc / MCocoa - code.google.com/p/mobjc and code.google.com/p/mcocoa ObjC# - www.mono-project.com/ObjCSharp

  • JQuery Menu plugins under ASP.NET MVC seem to only work in Chrome, but not in IE & FireFox

    - by Antony
    Recently, I was trying to prototype some jQuery-based menu into ASP.NET MVC. Just to name two examples here: plugins.jquery.com/project/columnview www.filamentgroup.com/lab/jquery_ipod_style_and_flyout_menus/ Their demo page looks great, but when I integrate their sample code into MVC, the script no longer works in IE and FireFox, but it seems to work just fine under Google Chrome. Can someone kindly enough to point out what I missed? I will be honest here. I am still new to JavaScript, so it is still a learning phase to me, so any help is highly appreciated. I have placed a copy of my VS2010 solution zip file @ http://db.tt/0UNDkN Here is what I did. In the Site.Master, I have something like <body> <div class="page">{truncated...}</div> <script src="http://code.jquery.com/jquery-1.4.2.min.js" type="text/javascript" charset="utf-8"></script> <asp:ContentPlaceHolder ID="ScriptContent" runat="server" /> </body> And inside View file, I have the following <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <div id="original"> {some demo block, copied from javascript demo} </div> </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="ScriptContent" runat="server"> <script type="text/javascript" src="<%= Url.Content("~/Scripts/jquery.columnview.js") %>" /> <script type="text/javascript"> $(document).ready(function () { $('#original').columnview(); }); </script> </asp:Content> Compiled the code and ran it under IE. Ideally, it should work like the demo in www.christianyates.com/blog/jquery/finder-column-view-hierarchical-lists-jquery, but in reality, it only displays unordered list in plain view. (If you download the solution file and run it, you should be able to repro this as well). Next, tried with FireFox, not working either, same result as IE. Finally, when I try it under Google Chrome 4.1 (lastest version), and the script displays just fine. Really puzzling here :-/ Thank you for reading :D

  • Unique task queue task names only for active duration

    - by antony.trupe
    I want to guarantee that a task is not in a task queue more then once, so I generate a unique name based on it's payload. But, that task name is reserved for up to 7 days, which is not what I want; I only want it reserved for the duration the task is queued; it could be immediately re-queued. Once a Task with name N is written, any subsequent attempts to insert a Task named N will fail. Eventually (at least seven days after the task successfully executes), the task will be deleted and the name N can be reused. Is there a way to check if the named task is already in the queue then add it if it's not? Or a totally different approach?

  • What are the pros/cons to these 2 ways of defining parameters for a web service method

    - by Antony Scott
    I have an existing web service I need to expand, but it has not gone into production yet. So, I am free to change the contracts as I see fit. But I am not sure of the best way to define the methods. I am leaning towards Method 2 for no other reason than I cannot think of good names to give the parameters classes! Are there any major disadvantages to using Method 2 over Method 1? Method 1 [DataContract(Namespace = Constants.ServiceNamespace)] public class MyParameters { [DataMember(Order = 1, IsRequired = true)] public int CompanyID { get; set; } [DataMember(Order = 2, IsRequired = true)] public string Filter { get; set; } } [ServiceContract(Namespace = Constants.ServiceNamespace)] public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(MyParameters params); } Method 2 public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(int companyID, string filter); }

  • Problem with pattern matching in ocaml

    - by Antony
    I wrote the function used to decompose a Boolean function, the problem is that the compilation I get this : "Warning 5: this function application is partial, maybe some arguments are missing." How can I solve this problem? I've set wrong the patter matching or I can not run this operation with pattern matching The code is the following: let rec decomposition state_init state prec formula = match formula with And form -> (fun () -> let f1 = List.hd form in let f2 = And(List.tl form )in let new_state = Forms (state_init,f1) in decomposition state_init new_state state f1; decomposition state_init new_state state f2; Hashtbl.add graph new_state (("",false,state :: []) , []) ; let x = Hashtbl.find graph state in let succ = state :: snd x in let (desc,last,ptrs) = fst x in Hashtbl.replace graph state ( ("And-node",last,ptrs) , succ))

  • How can I get access to spring container?

    - by Antony
    I have a spring container running, and I have class with which I want to have access to the bean created inside spring container. The class I have is not registered with the spring container. One thing I can do is that I can use MethodInvoker to call a static method, so I will have access to static field (this would be a bean from spring container) in my class always. Do we have class like WebapplicationContextUtils for a application that is not web?
