  • JPA and aggregate functions. How do I use the result of the query?

    - by Bogdan
    Hey guys, I'm new to ORM stuff and I need some help understanding something. Let's assume I have the following standard SQL query: SELECT *, COUNT(test.testId) AS noTests FROM inspection LEFT JOIN test ON inspection.inspId = test.inspId GROUP BY inspection.inspId which I want to use in JPA. I have an Inspection entity with a one-to-many relationship to a Test entity. (an inspection has many tests) I tried writing this in JPQL: Query query = em.createQuery("SELECT insp, COUNT(???what???) FROM Inspection insp LEFT JOIN insp.testList " + "GROUP BY insp.inspId"); 1) How do I write the COUNT clause? I'd have to apply count to elements from the test table but testList is a collection, so I can't do smth like COUNT(insp.testList.testId) 2) Assuming 1 is resolved, what type of object will be returned. It will definitely not be an Inspection object... How do I use the result?

  • Programmatically triggering events in Javascript for IE using jQuery

    - by Dan Herbert
    When an Event is triggered by a user in IE, it is set to the window.event object. The only way to see what triggered the event is by accessing the window.event object (as far as I know) This causes a problem in ASP.NET validators if an event is triggered programmatically, like when triggering an event through jQuery. In this case, the window.event object stores the last user-triggered event. When the onchange event is fired programmatically for a text box that has an ASP.NET validator attached to it, the validation breaks because it is looking at the element that fired last event, which is not the element the validator is for. Does anyone know a way around this? It seems like a problem that is solvable, but from looking online, most people just find ways to ignore the problem instead of solving it. To explain what I'm doing specifically: I'm using a jQuery time picker plugin on a text box that also has 2 ASP.NET validators associated with it. When the time is changed, I'm using an update panel to post back to the server to do some things dynamically, so I need the onchange event to fire in order to trigger the postback for that text box. The jQuery time picker operates by creating a hidden unordered list that is made visible when the text box is clicked. When one of the list items is clicked, the "change" event is fired programmatically for the text box through jQuery's change() method. Because the trigger for the event was a list item, IE sees the list item as the source of the event, not the text box, like it should. I'm not too concerned with this ASP.NET validator working as soon as the text box is changed, I just need the "change" event to be processed so my postback event is called for the text box. The problem is that the validator throws an exception in IE which stops any event from being triggered. Firefox (and I assume other browsers) don't have this issue. Only IE due to the different event model. Has anyone encountered this and seen how to fix it? I've found this problem reported several other places, but they offer no solutions: jQuery's forum, with the jQuery UI Datepicker and an ASP.NET Validator ASP.NET forums, bug with ValidatorOnChange() function

  • GEM Version Requirements Depreciated

    - by Kevin Sylvestre
    When creating a new Rails project using: rails sample Then creating a model using: script/generate model person first_name:string last_name:string Everything is fine. However, if I add any gems to my environment.rb: config.gem "authlogic" And run the same generator, I get the following: /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. The warning just recently appeared (I think), but I would like to fix it if possible. Any hints or similar experiences? Thanks.

  • ASP.NET Compiles on page load, but not on Ctrl+Shift+B

    - by Steve Syfuhs
    during debug in cassini the code runs fine, but when I explictly build it, the compile breaks on an object saying it can't find the reference. During a breakpoint shows the proper reference to the object, and I can view the debug intellisense. The code itself is simple using CFTW.Controls; ... controls_LatestPresentations c = LoadControl("~/controls/LatestPresentations.ascx") as controls_LatestPresentations; c.loadContent(); return RenderControl(c); The control is a simple user control, with the namespace CFTW.Controls. The calling code is in a webcontrol, which lives in the same folder. I even tried adding the calling code to the same namespace.

  • How do I compile on linux to share with all distributions?

    - by Andrew M
    I compiled a PHP extension on Fedora Core 12, but when I send it to someone using CentOS they get the error: "ELF file OS ABI invalid" I'm not sure what causes this running file provides the following info: ELF 64-bit LSB shared object, AMD x86-64, version 1 (GNU/Linux), not stripped An extension that loads fine provides the following from file: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), not stripped So it seems I need to generate a SYSV type file for some distributions, instead of a GNU/LINUX file, no idea how though. Any pointers? Also should I be statically linking?

  • Does isolation frameworks (Moq, RhinoMock, etc) lead to test overspecification?

    - by Marius
    In Osherove's great book "The Art of Unit Testing" one of the test anti-patterns is over-specification which is basically the same as testing the internal state of the object instead of some expected output. To my experience, using Isolation frameworks can cause the same unwanted side effects as testing internal behavior because one tends to only implement the behavior necessary to make your stub interact with the object under test. Now if your implementation changes later on (but the contract remains the same), your test will suddenly break because you are expecting some data from the stub which was not implemented. So what do you think is the best approach to counter this? 1) Implement your stubs/mocks fully, this has the negative side-effect of potentially making your test less readable and also specifying more than necessary to make your test pass. 2) Favor manual, fully implemented fakes. 3) Implement your stubs/fakes so that they make your test just pass, and then deal with the brittleness that this might introduce.

  • Should I use Spring or Guice for a Tomcat/Wicket/Hibernate project?

    - by Trevor Allred
    I'm building a new web application that uses Linux, Apache, Tomcat, Wicket, JPA/Hibernate, and MySQL. My primary need is Dependency Injection, which both Spring and Guice can do well. I think I need transaction support that would come with Spring and JTA but I'm not sure. The site will probably have about 20 pages and I'm not expect huge traffic. Should I use Spring or Guice? Feel free to ask and followup questions and I'll do my best to update this.

  • How to edit default.aspx on SharePoint site without SharePoint Designer

    - by Magnus Johansson
    On several occations, I have faced the situation that the default.aspx page on a Site doesn't work. More specifically, a reference to a WebPart and/or Control is throwing a error because the assembly is not found. Fine, you just fire up the dreaded SharePoint Designer and remove the dependency line. However, if I wanted to use this method when not having SharePoint Designer, how could this be done? EDIT: Removing the web part using the "?contents=1" web part management page didn't help in my case. The <%@Register tag was still there and had to be removed using SharePoint Designer.

  • Maven project dependecy against JDK version

    - by Andrea Polci
    I have projects that need to be build with a specific version of the JDK. The problem isn't in the source and target parameters but in the jars of the runtime used during compilation. In some cases I get a compilation error if I try to compile with the wrong JDK, but sometimes the build is successful and I get runtime errors when using the jars. For example in eclipse I have the ability to establish the execution enviroment for the project in the .classpath file. Is there a way to handle such situation in maven? What I would like to have is the ability to handle JRE dependency like other dependencies of the project in the POM file.

  • Connection Pooling

    - by cshah
    I have the following code, If I use conn == null in finally do I still use connection pooling? I know it is a good practice to close your connection but how about disposing the whole connection object? public void ExecuteNonQuery(SqlCommand Cmd) { //========== Connection ==========// SqlConnection Conn = new SqlConnection(strConStr); try { //========== Open Connection ==========// Conn.Open(); //========== Execute Command ==========// Cmd.Connection = Conn; Cmd.CommandTimeout = 180; Cmd.ExecuteNonQuery(); } catch (Exception Exc) { throw Exc; } finally { //======== Closing Connection ========// if (Conn.State == ConnectionState.Open) { Conn.Close(); } //======== Disposing object ========// Conn = null; } }

  • Specializing a template on a lambda in C++0x

    - by Tony A.
    I've written a traits class that lets me extract information about the arguments and type of a function or function object in C++0x (tested with gcc 4.5.0). The general case handles function objects: template <typename F> struct function_traits { template <typename R, typename... A> struct _internal { }; template <typename R, typename... A> struct _internal<R (F::*)(A...)> { // ... }; typedef typename _internal<decltype(&F::operator())>::<<nested types go here>>; }; Then I have a specialization for plain functions at global scope: template <typename R, typename... A> struct function_traits<R (*)(A...)> { // ... }; This works fine, I can pass a function into the template or a function object and it works properly: template <typename F> void foo(F f) { typename function_traits<F>::whatever ...; } int f(int x) { ... } foo(f); What if, instead of passing a function or function object into foo, I want to pass a lambda expression? foo([](int x) { ... }); The problem here is that neither specialization of function_traits<> applies. The C++0x draft says that the type of the expression is a "unique, unnamed, non-union class type". Demangling the result of calling typeid(...).name() on the expression gives me what appears to be gcc's internal naming convention for the lambda, main::{lambda(int)#1}, not something that syntactically represents a C++ typename. In short, is there anything I can put into the template here: template <typename R, typename... A> struct function_traits<????> { ... } that will allow this traits class to accept a lambda expression?

  • How to Execute Page_Load() in Page's Base Class?

    - by DaveDev
    I have the following PerformanceFactsheet.aspx.cs page class public partial class PerformanceFactsheet : FactsheetBase { protected void Page_Load(object sender, EventArgs e) { // do stuff with the data extracted in FactsheetBase divPerformance.Controls.Add(this.Data); } } where FactsheetBase is defined as public class FactsheetBase : System.Web.UI.Page { public MyPageData Data { get; set; } protected void Page_Load(object sender, EventArgs e) { // get data that's common to all implementors of FactsheetBase // and store the values in FactsheetBase's properties this.Data = ExtractPageData(Request.QueryString["data"]); } } The problem is that FactsheetBase's Page_Load is not executing. Can anyone tell me what I'm doing wrong? Is there a better way to get the result I'm after? Thanks

  • Data persistance with BufferedReader and PrintWriter?

    - by Nazgulled
    I have this simple application with a couple of classes which are all related. There's one, the main one, for which there is only one instance of. I need to save save and load that using a text stream. My instructor requirement is BufferedReader to load the stream and PrintWriter to save it. But is this even possible? To persist a data object/class with a text stream? I know how to do it with and object, using serialization. But I don't see how am I supposed to do it using text streams. Suggestions?

  • Serialising and Deserialising Requests and Responses exactly as WCF does

    - by PeteAC
    I need to deserialise SOAP request XML to .Net request object and to serialise .Net response object to SOAP response XML. I need this to work exactly as WCF does, using the same XML element local names and namespace URIs. The .Net request and response classes were generated from WSDL using SVCUTIL. I have looked at XmlSerializer class, which does most of it, but doesn't take notice of certain WCF-specific custom attributes, like MessageBodyMemberAttribute. I also looked at DataContractSerializer, but that had exceedingly strange ideas about what element names and namespaces to use. Finally, I tried XmlSerializer with an XmlTypeMapping generated by a SoapReflectionImporter; this didn't seem to use any namespaces at all. I rather suspect that I need to be using one of the above techniques, but with some additional subtlety, of which I am unaware. But perhaps there is an entirely different approach? All suggestions welcome.

  • C#.NET: FTP Several Files

    - by Steve Kiss
    Hi, I have what would seem like a common problem, but I cannot find an appropriate solution on any forums. I need to FTP an entire directory structure using .NET. I have found several code examples all of which show how you can FTP a single file by creating an FtpWebRequest object. Unfortunately, there is no information on how to deal with several files. Do I simply create a FtpWebRequest object for every single file? Any help would be appreciated. Thanks

  • How to batch retrieve documents with mongoDB?

    - by edude05
    Hello everyone, I have an application that queries data from a mongoDB using the mongoDB C# driver something like this: public void main() { foreach (int i in listOfKey) { list.add(getObjectfromDB(i); } } public myObject getObjFromDb(int primaryKey) { document query = new document(); query["primKey"] = primaryKey; document result= mongo["myDatabase"]["myCollection"].findOne(query); return parseObject(result); } On my local (development) machine to get 100 object this way takes less than a second. However, I recently moved the database to a server on the internet, and this query takes about 30 seconds to execute for the same number of object. Furthermore, looking at the mongoDB log, it seems to open about 8-10 connections to the DB to perform this query. So what I'd like to do is have the query the database for an array of primaryKeys and get them all back at once, then do the parsing in a loop afterwards, using one connection if possible. How could I optimize my query to do so? Thanks, --Michael

  • NSFetchedResultsChangeInsert reported when only updates are taking place

    - by niblha
    I have a class that acts as a NSFetchedResultsControllerDelegate which is receiving messages to -(void)controller:didChangeObject:atIndexPath:forChangeType:newIndexPath: with change type NSFetchedResultsChangeInsert, but the actual object which is the subject has with certainty not been newly inserted, only updated. So I would expect to get a change message with type NSFetchedResultsChangeUpdate, should I not? If i check the value of isInserted on the object, it yields false (as expected from the logic in my program). So my question is, why is this reported as an insert when it is only a change/update? They only thing I can think of is that part of the changes that are taking place is that objects of another entity type are inserted with relationships to objects of the entity type that the NSFetchedResultsController is set up to fetch.

  • Right design to validate attributes of a class instance

    - by systempuntoout
    Having a simple Python class like this: class Spam(object): __init__(self, description, value): self.description = description self.value = value Which is the correct approach to check these constraints: "description cannot be empty" "value must be greater than zero" Should i: 1.validate data before creating spam object ? 2.check data on __init__ method ? 3.create an is_valid method on Spam class and call it with spam.isValid() ? 4.create an is_valid static method on Spam class and call it with Spam.isValid(description, value) ? 5.check data on setters? 6.... Could you recommend a well designed\Pythonic\not verbose (on class with many attributes)\elegant approach?

  • Model of hql query firing at back end by hql engine?

    - by Maddy.Shik
    I want to understand how hibernate execute hql query internally or in other models how hql query engine works. Please suggest some good links for same? One of reason for reading is following problem. Class Branch { //lazy loaded @joincolumn(name="company_id") Company company; } Since company is heavy object so it is lazy loaded. now i have hql query "from Branch as branch where branch.Company.id=:companyId" my concern is that if for firing above query, hql engine has to retrieve company object then its a performance hit and i would prefer to add one more property in Branch class i.e. companyId. So in this case hql query would be "from Branch as branch where branch.companyId=:companyId" If hql engine first generate sql from hql followed by firing of sql query itself, then there should be no performance issue. Please let me know if problem is not understandable.
