  • How do I Integrate Production Database Hot Fixes into Shared Database Development model?

    - by TetonSig
    We are using SQL Source Control 3, SQL Compare, SQL Data Compare from RedGate, Mercurial repositories, TeamCity and a set of 4 environments including production. I am working on getting us to a dedicated environment per developer, but for at least the next 6 months we are stuck with a shared model. To summarize our current system, we have a DEV SQL server where developers first make changes/additions. They commit their changes through SQL Source Control to a local hgdev repository. When they execute an hg push to the main repository, TeamCity listens for that and then (among other things) pushes hgdev repository to hgrc. Another TeamCity process listens for that and does a pull from hgrc and deploys the latest to a QA SQL Server where regression and integration tests are run. When those are passed a push from hgrc to hgprod occurs. We do a compare of hgprod to our PREPROD SQL Server and generate deployment/rollback scripts for our production release. Separate from the above we have database Hot Fixes that will need to be applied in between releases. The process there is for our Operations team make changes on the PreProd database, and then after testing, to use SQL Source Control to commit their hot fix changes to hgprod from the PREPROD database, and then do a compare from hgprod to PRODUCTION, create deployment scripts and run them on PRODUCTION. If we were in a dedicated database per developer model, we could simply automatically push hgprod back to hgdev and merge in the hot fix change (through TeamCity monitoring for hgprod checkins) and then developers would pick it up and merge it to their local repository and database periodically. However, given that with a shared model the DEV database itself is the source of all changes, this won't work. Pushing hotfixes back to hgdev will show up in SQL Source Control as being different than DEV SQL Server and therefore we need to overwrite the reposistory with the "change" from the DEV SQL Server. My only workaround so far is to just have OPS assign a developer the hotfix ticket with a script attached and then we run their hotfixes against DEV ourselves to merge them back in. I'm not happy with that solution. Other than working faster to get to dedicated environment, are they other ways to keep this loop going automatically?

  • Why do meshes show up as bones in the Model class?

    - by Itamar Marom
    Right now I'm working on a 3D game and I've come across something very weird. When I created the model in Blender, I added an armature named "MyBone" to the stage and attached a cube ("MyCube") to it, so that when I move the armature, the cube moves with it. I exported this as an FBX and loaded it as a Model object. What I expected to see was: But what I got was this: I'm really confused. Why is the mesh I created showing up in the bone list? And what's Root Node? Here are the .blend and .fbx files: here or here. Thanks.

  • Let a model instance choose appropriate view class using category. Is it good design?

    - by Denis Mikhaylov
    Assume I have abstract base model class called MoneySource. And two realizations BankCard and CellularAccount. In MoneysSourceListViewController I want to display a list of them, but with ListItemView different for each MoneySource subclass. What if I define a category on MoneySource @interface MoneySource (ListItemView) - (Class)listItemViewClass; @end And then override it for each concrete sublcass of MoneySource, returning suitable view class. @implementation CellularAccount (ListItemView) - (Class)listItemViewClass { return [BankCardListView class]; } @end @implementation BankCard (ListItemView) - (Class)listItemViewClass { return [CellularAccountListView class]; } @end so I can ask model object about its view, not violating MVC principles, and avoiding class introspection or if constructions. Thank you!

  • Core Data Migration - "Can't add source store" error

    - by Tofrizer
    Hi, In my iPhone app I'm using Core Data and I've made changes to my data model that cannot be automatically migrated over (i.e. added new relationships). I added the data model version (Design - Data Model - Add Model Version) and applied my new data model changes to the new version 2. I then created a mapping object model and set the Source and Destination models to their correct data models (old and new respectively). When I run the app and call the persistentStoreCoordinator, my app barfs with the following: 2010-02-27 02:40:30.922 XXXX[73578:20b] Unresolved error Error Domain=NSCocoaErrorDomain Code=134110 UserInfo=0xfc2240 "Operation could not be completed. (Cocoa error 134110.)", { NSUnderlyingError = Error Domain=NSCocoaErrorDomain Code=134130 UserInfo=0xfbb3a0 "Operation could not be completed. (Cocoa error 134130.)"; reason = "Can't add source store"; } FWIW (not much i think) I've also made the usual code changes in persistentStoreCoordinator to use the NSMigratePersistentStoresAutomaticallyOption and NSInferMappingModelAutomaticallyOption (for future data model changes that can be automatically migrated). More relevantly, my managedObjectModel is created by calling initWithContentsOfURL where the file/resource type is "momd". I've tried updating both the source and destination model in the mapping model (Design - Mapping Model - Update XXX Model) as well as deleted the mapping model and recreated it. I've cleaned and re-built but all to no avail. I still get the above error message. Any pointers/thoughts on how I can further debug or resolve this problem please? I haven't posted any code snippets because this feels much more like a build environment issue (and my code is very standard - just the usual core data code to handle migrations using a mapping model but I'm happy to show the code if it helps). Appreciate any help. Thanks

  • Box2dx: Usage of World.QueryAABB?

    - by Rosarch
    I'm using Box2dx with C#/XNA. I'm trying to write a function that determines if a body could exist in a given point without colliding with anything: /// <summary> /// Can gameObject exist with start Point without colliding with anything? /// </summary> internal bool IsAvailableArea(GameObjectModel model, Vector2 point) { Vector2 originalPosition = model.Body.Position; model.Body.Position = point; // less risky would be to use a deep clone AABB collisionBox; model.Body.GetFixtureList().GetAABB(out collisionBox); // how is this supposed to work? physicsWorld.QueryAABB(x => true, ref collisionBox); model.Body.Position = originalPosition; return true; } Is there a better way to go about doing this? How is World.QueryAABB supposed to work? Here is an earlier attempt. It is broken; it always returns false. /// <summary> /// Can gameObject exist with start Point without colliding with anything? /// </summary> internal bool IsAvailableArea(GameObjectModel model, Vector2 point) { Vector2 originalPosition = model.Body.Position; model.Body.Position = point; // less risky would be to use a deep clone AABB collisionBox; model.Body.GetFixtureList().GetAABB(out collisionBox); ICollection<GameObjectController> gameObjects = worldQueryEngine.GameObjectsForPredicate(x => ! x.Model.Passable); foreach (GameObjectController controller in gameObjects) { AABB potentialCollidingBox; controller.Model.Body.GetFixtureList().GetAABB(out potentialCollidingBox); if (AABB.TestOverlap(ref collisionBox, ref potentialCollidingBox)) { model.Body.Position = originalPosition; return false; // there is something that will collide at this point } } model.Body.Position = originalPosition; return true; }

  • Can I ReRender a JSF Component from backing bean code?

    - by Ben
    Hi, Can I rerender a jsf ui component when a valuechangelistener method is run? The reason i'm asking is that my valuechangelistener method changes the values of the input boxes but when I run it, they don't seem to be rerender. The following doesn't work: <h:inputText id="inputbox_id"/> <h:selectOneMenu valueChangeListener="#{myBean.changeCountryMenu}"> <a4j:support event="onchange" rerender="inputbox_id" action="#{bean.test}> </h:selectOneMenu> Notice that bean.test() is never run. So the solution I thought of is to rerender the inputbox from the valueChangeListener. If there is some other better solution i'd be glad to hear... Thank you! Ben.

  • Big smart ViewModels, dumb Views, and any model, the best MVVM approach?

    - by Edward Tanguay
    The following code is a refactoring of my previous MVVM approach (Fat Models, skinny ViewModels and dumb Views, the best MVVM approach?) in which I moved the logic and INotifyPropertyChanged implementation from the model back up into the ViewModel. This makes more sense, since as was pointed out, you often you have to use models that you either can't change or don't want to change and so your MVVM approach should be able to work with any model class as it happens to exist. This example still allows you to view the live data from your model in design mode in Visual Studio and Expression Blend which I think is significant since you could have a mock data store that the designer connects to which has e.g. the smallest and largest strings that the UI can possibly encounter so that he can adjust the design based on those extremes. Questions: I'm a bit surprised that I even have to "put a timer" in my ViewModel since it seems like that is a function of INotifyPropertyChanged, it seems redundant, but it was the only way I could get the XAML UI to constantly (once per second) reflect the state of my model. So it would be interesting to hear anyone who may have taken this approach if you encountered any disadvantages down the road, e.g. with threading or performance. The following code will work if you just copy the XAML and code behind into a new WPF project. XAML: <Window x:Class="TestMvvm73892.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:TestMvvm73892" Title="Window1" Height="300" Width="300"> <Window.Resources> <ObjectDataProvider x:Key="DataSourceCustomer" ObjectType="{x:Type local:CustomerViewModel}" MethodName="GetCustomerViewModel"/> </Window.Resources> <DockPanel DataContext="{StaticResource DataSourceCustomer}"> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=FirstName}"/> <TextBlock Text=" "/> <TextBlock Text="{Binding Path=LastName}"/> </StackPanel> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=TimeOfMostRecentActivity}"/> </StackPanel> </DockPanel> </Window> Code Behind: using System; using System.Windows; using System.ComponentModel; using System.Threading; namespace TestMvvm73892 { public partial class Window1 : Window { public Window1() { InitializeComponent(); } } //view model public class CustomerViewModel : INotifyPropertyChanged { private string _firstName; private string _lastName; private DateTime _timeOfMostRecentActivity; private Timer _timer; public string FirstName { get { return _firstName; } set { _firstName = value; this.RaisePropertyChanged("FirstName"); } } public string LastName { get { return _lastName; } set { _lastName = value; this.RaisePropertyChanged("LastName"); } } public DateTime TimeOfMostRecentActivity { get { return _timeOfMostRecentActivity; } set { _timeOfMostRecentActivity = value; this.RaisePropertyChanged("TimeOfMostRecentActivity"); } } public CustomerViewModel() { _timer = new Timer(CheckForChangesInModel, null, 0, 1000); } private void CheckForChangesInModel(object state) { Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, this); } public static CustomerViewModel GetCustomerViewModel() { CustomerViewModel customerViewModel = new CustomerViewModel(); Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, customerViewModel); return customerViewModel; } public static void MapFieldsFromModeltoViewModel(Customer model, CustomerViewModel viewModel) { viewModel.FirstName = model.FirstName; viewModel.LastName = model.LastName; viewModel.TimeOfMostRecentActivity = model.TimeOfMostRecentActivity; } public static Customer GetCurrentCustomer() { return Customer.GetCurrentCustomer(); } //INotifyPropertyChanged implementation public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged(string property) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } } //model public class Customer { public string FirstName { get; set; } public string LastName { get; set; } public DateTime TimeOfMostRecentActivity { get; set; } public static Customer GetCurrentCustomer() { return new Customer { FirstName = "Jim", LastName = "Smith", TimeOfMostRecentActivity = DateTime.Now }; } } }

  • How to pass get-parameter to backing bean in jsf?

    - by Roman
    I have get parameter with name controller. When I try to pass it (with propertyChangeListener) to my backing bean I get null instead of the real value of the parameter: <h:commandButton value="#{msg['mail.send']}" styleClass="mailbutton" action="#{mailSender.sendMail}"> <f:setPropertyActionListener target="#{mailSender.controllerName}" value="{#param.controller}"/> </h:commandButton> So, I have two questions: What is the proper way to set bean property with a get-parameter value? Actually, I've already get the value from ExternalContext#getRequestParam but maybe there are some other solutions. More interesting question: why propertyActionListener didn't work here? What does it do actually? (again I have some thoughts about it but it would be nice to read more comprehensive explanations).

  • After extending the User model in django, how do you create a ModelForm?

    - by mlissner
    I extended the User model in django to include several other variables, such as location, and employer. Now I'm trying to create a form that has the following fields: First name (from User) Last name (from User) Location (from UserProfile, which extends User via a foreign key) Employer (also from UserProfile) I have created a modelform: from django.forms import ModelForm from django.contrib import auth from alert.userHandling.models import UserProfile class ProfileForm(ModelForm): class Meta: # model = auth.models.User # this gives me the User fields model = UserProfile # this gives me the UserProfile fields So, my question is, how can I create a ModelForm that has access to all of the fields, whether they are from the User model or the UserProfile model? Hope this makes sense. I'll be happy to clarify if there are any questions.

  • How can I pass a dynamic backing bean into a JSF 2.0 page using facelets?

    - by kgrad
    Hi, I am using a JSF 2.0 to create a web app (purely jee6, without spring/seam etc.). I would like to have a single xhtml page but pass the proper backing bean / entity into it. For example, I would like to be able to edit a user other than the logged in user, I have a user edit page which displays the information of the logged in user (being tracked by my session), I would like to instead pass in a user selected from a list and edit that user's information, without switching the user that is stored in the session or creating a separate xhtml page (violating DRY). The "best" way I can see to achieve this would be to reuse the exact same xhtml page that I am using to display the logged-in-user's edit page, but simply pass in a different entity in some way. Perhaps calling the setter in the backing bean before redirecting to the page (if this is even possible) or some other solution that does not violate DRY. Perhaps I have designed this all wrong, is there a way to pass in entities to JSF pages? thanks.

  • How to make a legacy webapp spring aware at the container level for bean autowire into Servlets?

    - by Pete
    We have a legacy web application (not Spring based) and are looking for best practices to autowire some newer Spring configured (thread safe) service beans into instance variables in several of the legacy servlets. Rewriting every servlet to Spring MVC is out of scope. For testability, we do not want any Spring specific bean lookup code in the Servlets to look up beans by name or similar. Note that we are not concerned about web specific bean scopes such as session or request; all services are singleton scope. Below shows relevant code snippet MyServlet extends LegacyServletSuperclass { private MyThreadSafeServiceBean wantThisToBeAutowiredBySpring; .... }

  • JSF, How to set a property in a different page/backing bean and then navigate to that page?

    - by kgrad
    I am using JSF 2.0 and attempting to pass values between different pages in my App. The setup is as follows: I have a page called userSelect that has a backing bean userSelectBacking. On this page I display a list of users that can be selected and submit using an h:commandbutton, when the page is submit the navigation goes to a userEdit page. I have a page called userEdit, that has a backing bean userEditBacking which displays the information for a user and allows that user to be edited. I would like to pass the user selected from the userSelect page into the userEdit page. I am currently using f:setPropertyActionListener to set the user in my userEdit backing from the userSelect page, however when I navigate to the userEdit page, it loses the information I set. is there a way that I can pass the values between the two pages/backing beans? thanks

  • Should I design the application or model (database) first?

    - by YonahW
    I am getting ready to start building a new web project in my spare time to bring to fruition an idea that has been bouncing around my head for a while. I have never gotten down whether I am better off first building the model and then the consuming application or the other way around. What are the best practices? What would you build first and why? I imagine that in general the application should generally drive the model, however the application like many websites really doesn't do much without the model. For some reason I find it easier at times to think in terms of the model since the application is really just actions on the model. Is this a poor way of thinking about things? What advantages/disadvantages does each option have?

  • How can I not render a button in my view if a given property off my model has no value?

    - by Lee Warner
    I'm new to web development. In my view, I want to conditionally show a button if Model.TemplateLocation (which is a string) is not null or empty. Below is the code that is rendering the button currently: <div class="WPButton MyButton"> <%=Html.ActionLink(Model.TemplateLinkName, "DownloadTemplate", "ExternalData", new ArgsDownloadTemplate { Path = Model.TemplateLocation, FileName = Model.TemplateFileNameForDownload }, new{})%> </div> Can I wrap some C# code in the <% %'s to test for Model.TemplateLocations value before I render that? I was told to look into @style = "display:none" somehow. Could that be what I need?

  • How to invoke the getView method in the baseAdapter in Android from another WebService Bean?

    - by greysh
    The adapter in my code as follows, I extends the base adapter: @Override public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder vHolder; // if (convertView == null) { vHolder = new ViewHolder(); convertView = mInflater.inflate(R.layout.home_item, null); vHolder.albumIcon = (ImageView) convertView .findViewById(R.id.albumIcon); try { Bitmap icon = aws.getAlbumImg(itemInfolist.get(position) .getAlbumInfoCol().get(0).getAlbumID(), 0); if (icon != null) { vHolder.albumIcon.setImageBitmap(icon); } else { vHolder.albumIcon.setImageBitmap(BitmapFactory.decodeResource( context.getResources(), R.drawable.album)); } } catch (Exception e) { vHolder.albumIcon.setImageBitmap(BitmapFactory.decodeResource( context.getResources(), R.drawable.album)); } convertView.setTag(vHolder); return convertView; } However, I download the imagine asynchronously, When invoke Bitmap icon = aws.getAlbumImg(itemInfolist.get(position).getAlbumInfoCol().get(0).getAlbumID(), 0); Some pictures which haven't downloaded will use the default image, after these picutures have downloaded in another Web Service Bean, I want the Web Service bean sends a message to invoke the getView method in this adapter in order to implement the auto refresh function. But if I change the Web Service Download Bean as follows,it will cause the exception 03-19 07:46:33.241: ERROR/AndroidRuntime(716): android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

  • What is good practice in .NET system architecture design concerning multiple models and aggregates

    - by BuzzBubba
    I'm designing a larger enterprise architecture and I'm in a doubt about how to separate the models and design those. There are several points I'd like suggestions for: - models to define - way to define models Currently my idea is to define: Core (domain) model Repositories to get data to that domain model from a database or other store Business logic model that would contain business logic, validation logic and more specific versions of forms of data retrieval methods View models prepared for specifically formated data output that would be parsed by views of different kind (web, silverlight, etc). For the first model I'm puzzled at what to use and how to define the mode. Should this model entities contain collections and in what form? IList, IEnumerable or IQueryable collections? - I'm thinking of immutable collections which IEnumerable is, but I'd like to avoid huge data collections and to offer my Business logic layer access with LINQ expressions so that query trees get executed at Data level and retrieve only really required data for situations like the one when I'm retrieving a very specific subset of elements amongst thousands or hundreds of thousands. What if I have an item with several thousands of bids? I can't just make an IEnumerable collection of those on the model and then retrieve an item list in some Repository method or even Business model method. Should it be IQueryable so that I actually pass my queries to Repository all the way from the Business logic model layer? Should I just avoid collections in my domain model? Should I void only some collections? Should I separate Domain model and BusinessLogic model or integrate those? Data would be dealt trough repositories which would use Domain model classes. Should repositories be used directly using only classes from domain model like data containers? This is an example of what I had in mind: So, my Domain objects would look like (e.g.) public class Item { public string ItemName { get; set; } public int Price { get; set; } public bool Available { get; set; } private IList<Bid> _bids; public IQueryable<Bid> Bids { get { return _bids.AsQueryable(); } private set { _bids = value; } } public AddNewBid(Bid newBid) { _bids.Add(new Bid {.... } } Where Bid would be defined as a normal class. Repositories would be defined as data retrieval factories and used to get data into another (Business logic) model which would again be used to get data to ViewModels which would then be rendered by different consumers. I would define IQueryable interfaces for all aggregating collections to get flexibility and minimize data retrieved from real data store. Or should I make Domain Model "anemic" with pure data store entities and all collections define for business logic model? One of the most important questions is, where to have IQueryable typed collections? - All the way from Repositories to Business model or not at all and expose only solid IList and IEnumerable from Repositories and deal with more specific queries inside Business model, but have more finer grained methods for data retrieval within Repositories. So, what do you think? Have any suggestions?

  • Why are transactions not rolling back when using SpringJUnit4ClassRunner/MySQL/Spring/Hibernate

    - by Trevor
    I am doing unit testing and I expect that all data committed to the MySQL database will be rolled back... but this isn't the case. The data is being committed, even though my log was showing that the rollback was happening. I've been wrestling with this for a couple days so my setup has changed quite a bit, here's my current setup. LoginDAOTest.java: @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"file:web/WEB-INF/applicationContext-test.xml", "file:web/WEB-INF/dispatcher-servlet-test.xml"}) @TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true) public class UserServiceTest { private UserService userService; @Test public void should_return_true_when_user_is_logged_in () throws Exception { String[] usernames = {"a","b","c","d"}; for (String username : usernames) { userService.logUserIn(username); assertThat(userService.isUserLoggedIn(username), is(equalTo(true))); } } ApplicationContext-Text.xml: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/test"/> <property name="username" value="root"/> <property name="password" value="Ecosim07"/> </bean> <tx:annotation-driven transaction-manager="transactionManager"/> <bean id="userService" class="Service.UserService"> <property name="userDAO" ref="userDAO"/> </bean> <bean id="userDAO" class="DAO.UserDAO"> <property name="hibernateTemplate" ref="hibernateTemplate"/> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="mappingResources"> <list> <value>/himapping/User.hbm.xml</value> <value>/himapping/setup.hbm.xml</value> <value>/himapping/UserHistory.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" p:sessionFactory-ref="sessionFactory"/> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> </bean> </beans> I have been reading about the issue, and I've already checked to ensure that the MySQL database tables are setup to use InnoDB. Also I have been able to successfully implement rolling back of transactions outside of my testing suite. So this must be some sort of incorrect setup on my part. Any help would be greatly appreciated :)

  • Using Spring as a JPA Container

    - by sdoca
    Hi, I found this article which talks about using Spring as a JPA container: http://java.sys-con.com/node/366275 I have never used Spring before this and am trying to make this work and hope someone can help me. In the article it states that you need to annotate a Spring bean with @Transactional and methods/fields with @PersistenceContext in order to provide transaction support and to inject an entity manager. Is there something the defines a bean as a "Spring Bean"? I have a bean class which implements CRUD operations on entities using generics: @Transactional public class GenericCrudServiceBean implements GenericCrudService { @PersistenceContext(unitName="MyData") private EntityManager em; @Override @PersistenceContext public <T> T create(T t) { em.persist(t); return t; } @Override @PersistenceContext public <T> void delete(T t) { t = em.merge(t); em.remove(t); } ... ... ... @Override @PersistenceContext public List<?> findWithNamedQuery(String queryName) { return em.createNamedQuery(queryName).getResultList(); } } Originally I only had this peristence context annotation: @PersistenceContext(unitName="MyData") private EntityManager em; but had a null em when findWithNamedQuery was invoked. Then I annotated the methods as well, but em is still null (no injection?). I was wondering if this had something to do with my bean not being recognized as "Spring". I have done configuration as best I could following the directions in the article including setting the following in my context.xml file: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns:tx="http://www.springframework.org/schema/tx" tx:schemaLocation="http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceUnitName" value="MyData" /> <property name="dataSource" ref="dataSource" /> <property name="loadTimeWeaver" class="org.springframework.classloading.ReflectiveLoadTimeWeaver" /> <property name="jpaVendorAdapter" ref="jpaAdapter" /> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" /> <property name="url" value="jdbc:oracle:thin:@localhost:1521:MySID" /> <property name="username" value="user" /> <property name="password" value="password" /> <property name="initialSize" value="3" /> <property name="maxActive" value="10" /> </bean> <bean id="jpaAdapter" class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"> <property name="databasePlatform" value="org.eclipse.persistence.platform.database.OraclePlatform" /> <property name="showSql" value="true" /> </bean> <bean class="org.springframework.ormmjpa.support.PersistenceAnnotationBeanPostProcessor" /> <tx:annotation-driven /> </beans> I guessed that these belonged in the context.xml file because the article never specifically said which file is the "application context" file. If this is wrong, please let me know.

  • Binding Entity Framework Collections Simply Using ASP.NET MVC

    - by jpcmorton
    To begin with: Using Entity Framework v4.0. ASP.NET MVC 2.0. Visual Studio 2010. I have a model that consists simply of an order & order items. What I want to do is simply bind that model without too much hassle where possible (avoiding type converters, etc). Simply the model looks like this: public class Order { public int ID { get; set; } public string OrderNumber { get; set; } public EntityCollection<OrderItem> Items { get; set; } } public class OrderItem { public int ID { get; set; } public string Qty { get; set; } } This is as simple as I want to keep it. This model is coming directly from the code generated by the entity framework generator. I would prefer to use the model directly from the entity framework (I know there are views saying this is a bad thing, but alas). I then have the View looking like this: <% using (Html.BeginForm()) {%> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%: Html.LabelFor(model => model.ID) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.ID) %> <%: Html.ValidationMessageFor(model => model.ID) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.OrderNumber) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.OrderNumber)%> <%: Html.ValidationMessageFor(model => model.OrderNumber)%> </div> <div id="lineItems"> Where I need to put my line items to be edited, inserted </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %> What I want to do is have a situation where I can use dynamic line items (using javascript). Problems are this: How to go about inserting the initial line item (within the lineItems div). This need to be strongly typed and use the built in validation framework of MVC. Best way to go about inserting line items dynamically so that on the postback there is a complete bind to the model without too much messing around (id = 1,2,3,4, etc). Any help, examples, tips, etc would be appreciated.

  • ASP.NET MVC Framework

    - by Aamir Hasan
     MVC is a design pattern. A reusable "recipe" for constructing your application. Generally, you don't want your user interface code and data access code to be mixed together, it makes changing either one more difficult. By placing data access code into a "Model" object and user interface code into a "View" object, you can use a "Controller" object to act as a go-between, sending messages/calling methods on the view object when the data changes and vice versa. Model-view-controller (MVC) is an architectural pattern used in software engineering. In complex computer applications that present a large amount of data to the user, a developer often wishes to separate data (model) and user interface (view) concerns, so that changes to the user interface will not affect data handling, and that the data can be reorganized without changing the user interface. The model-view-controller solves this problem by decoupling data access and business logic from data presentation and user interaction, by introducing an intermediate component: the controller.Model:    The domain-specific representation of the information that the application operates. Domain logic adds meaning to raw data (e.g., calculating whether today is the user's birthday, or the totals, taxes, and shipping charges for shopping cart items).    Many applications use a persistent storage mechanism (such as a database) to store data. MVC does not specifically mention the data access layer because it is understood to be underneath or encapsulated by the Model.View:    Renders the model into a form suitable for interaction, typically a user interface element. Multiple views can exist for a single model for different purposes.Controller:    Processes and responds to events, typically user actions, and may invoke changes on the model.

  • Finding the Right Solution to Source and Manage Your Contractors

    - by mark.rosenberg(at)oracle.com
    Many of our PeopleSoft Enterprise applications customers operate in service-based industries, and all of our customers have at least some internal service units, such as IT, marketing, and facilities. Employing the services of contractors, often referred to as "contingent labor," to deliver either or both internal and external services is common practice. As we've transitioned from an industrial age to a knowledge age, talent has become a primary competitive advantage for most organizations. Contingent labor offers talent on flexible terms; it offers the ability to scale up operations, close skill gaps, and manage risk in the process of delivering services. Talent comes from many sources and the rise in the contingent worker (contractor, consultant, temporary, part time) has increased significantly in the past decade and is expected to reach 40 percent in the next decade. Managing the total pool of talent in a seamless integrated fashion not only saves organizations money and increases efficiency, but creates a better place for workers of all kinds to work. Although the term "contingent labor" is frequently used to describe both contractors and employees who have flexible schedules and relationships with an organization, the remainder of this discussion focuses on contractors. The term "contingent labor" is used interchangeably with "contractor." Recognizing the importance of contingent labor, our PeopleSoft customers often ask our team, "What Oracle vendor management system (VMS) applications should I evaluate for managing contractors?" In response, I thought it would be useful to describe and compare the three most common Oracle-based options available to our customers. They are:   The enterprise licensed software model in which you implement and utilize the PeopleSoft Services Procurement (sPro) application and potentially other PeopleSoft applications;  The software-as-a-service model in which you gain access to a derivative of PeopleSoft sPro from an Oracle Business Process Outsourcing Partner; and  The managed service provider (MSP) model in which staffing industry professionals utilize either your enterprise licensed software or the software-as-a-service application to administer your contingent labor program. At this point, you may be asking yourself, "Why three options?" The answer is that since there is no "one size fits all" in terms of talent, there is also no "one size fits all" for effectively sourcing and managing contingent workers. Various factors influence how an organization thinks about and relates to its contractors, and each of the three Oracle-based options addresses an organization's needs and preferences differently. For the purposes of this discussion, I will describe the options with respect to (A) pricing and software provisioning models; (B) control and flexibility; (C) level of engagement with contractors; and (D) approach to sourcing, employment law, and financial settlement. Option 1:  Enterprise Licensed Software In this model, you purchase from Oracle the license and support for the applications you need. Typically, you license PeopleSoft sPro as your VMS tool for sourcing, monitoring, and paying your contract labor. In conjunction with sPro, you can also utilize PeopleSoft Human Capital Management (HCM) applications (if you do not already) to configure more advanced business processes for recruiting, training, and tracking your contractors. Many customers choose this enterprise license software model because of the functionality and natural integration of the PeopleSoft applications and because the cost for the PeopleSoft software is explicit. There is no fee per transaction to source each contractor under this model. Our customers that employ contractors to augment their permanent staff on billable client engagements often find this model appealing because there are no fees to affect their profit margins. With this model, you decide whether to have your own IT organization run the software or have the software hosted and managed by either Oracle or another application services provider. Your organization, perhaps with the assistance of consultants, configures, deploys, and operates the software for managing your contingent workforce. This model offers you the highest level of control and flexibility since your organization can configure the contractor process flow exactly to your business and security requirements and can extend the functionality with PeopleTools. This option has proven very valuable and applicable to our customers engaged in government contracting because their contingent labor management practices are subject to complex standards and regulations. Customers find a great deal of value in the application functionality and configurability the enterprise licensed software offers for managing contingent labor. Some examples of that functionality are... The ability to create a tiered network of preferred suppliers including competencies, pricing agreements, and elaborate candidate management capabilities. Configurable alerts and online collaboration for bid, resource requisition, timesheet, and deliverable entry, routing, and approval for both resource and deliverable-based services. The ability to manage contractors with the same PeopleSoft HCM and Projects applications that are used to manage the permanent workforce. Because it allows you to utilize much of the same PeopleSoft HCM and Projects application functionality for contractors that you use for permanent employees, the enterprise licensed software model supports the deepest level of engagement with the contingent workforce. For example, you can: fill job openings with contingent labor; guide contingent workers through essential safety and compliance training with PeopleSoft Enterprise Learning Management; and source contingent workers directly to project-based assignments in PeopleSoft Resource Management and PeopleSoft Program Management. This option enables contingent workers to collaborate closely with your permanent staff on complex, knowledge-based efforts - R&D projects, billable client contracts, architecture and engineering projects spanning multiple years, and so on. With the enterprise licensed software model, your organization maintains responsibility for the sourcing, onboarding (including adherence to employment laws), and financial settlement processes. This means your organization maintains on staff or hires the expertise in these domains to utilize the software and interact with suppliers and contractors. Option 2:  Software as a Service (SaaS) The effort involved in setting up and operating VMS software to handle a contingent workforce leads many organizations to seek a system that can be activated and configured within a few days and for which they can pay based on usage. Oracle's Business Process Outsourcing partner, Provade, Inc., provides exactly this option to our customers. Provade offers its vendor management software as a service over the Internet and usually charges your organization a fee that is a percentage of your total contingent labor spending processed through the Provade software. (Percentage of spend is the predominant fee model, although not the only one.) In addition to lower implementation costs, the effort of configuring and maintaining the software is largely upon Provade, not your organization. This can be very appealing to IT organizations that are thinly stretched supporting other important information technology initiatives. Built upon PeopleSoft sPro, the Provade solution is tailored for simple and quick deployment and administration. Provade has added capabilities to clone users rapidly and has simplified business documents, like work orders and change orders, to facilitate enterprise-wide, self-service adoption with little to no training. Provade also leverages Oracle Business Intelligence Enterprise Edition (OBIEE) to provide integrated spend analytics and dashboards. Although pure customization is more limited than with the enterprise licensed software model, Provade offers a very effective option for organizations that are regularly on-boarding and off-boarding high volumes of contingent staff hired to perform discrete support tasks (for example, order fulfillment during the holiday season, hourly clerical work, desktop technology repairs, and so on) or project tasks. The software is very configurable and at the same time very intuitive to even the most computer-phobic users. The level of contingent worker engagement your organization can achieve with the Provade option is generally the same as with the enterprise licensed software model since Provade can automatically establish contingent labor resources in your PeopleSoft applications. Provade has pre-built integrations to Oracle's PeopleSoft and the Oracle E-Business Suite procurement, projects, payables, and HCM applications, so that you can evaluate, train, assign, and track contingent workers like your permanent employees. Similar to the enterprise licensed software model, your organization is responsible for the contingent worker sourcing, administration, and financial settlement processes. This means your organization needs to maintain the staff expertise in these domains. Option 3:  Managed Services Provider (MSP) Whether you are using the enterprise licensed model or the SaaS model, you may want to engage the services of sourcing, employment, payroll, and financial settlement professionals to administer your contingent workforce program. Firms that offer this expertise are often referred to as "MSPs," and they are typically staffing companies that also offer permanent and temporary hiring services. (In fact, many of the major MSPs are Oracle applications customers themselves, and they utilize the PeopleSoft Solution for the Staffing Industry to run their own business operations.) Usually, MSPs place their staff on-site at your facilities, and they can utilize either your enterprise licensed PeopleSoft sPro application or the Provade VMS SaaS software to administer the network of suppliers providing contingent workers. When you utilize an MSP, there is a separate fee for the MSP's service that is typically funded by the participating suppliers of the contingent labor. Also in this model, the suppliers of the contingent labor (not the MSP) usually pay the contingent labor force. With an MSP, you are intentionally turning over business process control for the advantages associated with having someone else manage the processes. The software option you choose will to a certain extent affect your process flexibility; however, the MSPs are often able to adapt their processes to the unique demands of your business. When you engage an MSP, you will want to give some thought to the level of engagement and "partnering" you need with your contingent workforce. Because the MSP acts as an intermediary, it can be very valuable in handling high volume, routine contracting for which there is a relatively low need for "partnering" with the contingent workforce. However, if your organization (or part of your organization) engages contingent workers for high-profile client projects that require diplomacy, intensive amounts of interaction, and personal trust, introducing an MSP into the process may prove less effective than handling the process with your own staff. In fact, in many organizations, it is common to enlist an MSP to handle contractors working on internal projects and to have permanent employees handle the contractor relationships that affect the portion of the services portfolio focused on customer-facing, billable projects. One of the key advantages of enlisting an MSP is that you do not have to maintain the expertise required for orchestrating the sourcing, hiring, and paying of contingent workers.  These are the domain of the MSPs. If your own staff members are not prepared to manage the essential "overhead" processes associated with contingent labor, working with an MSP can make solid business sense. Proper administration of a contingent workforce can make the difference between project success and failure, operating profit and loss, and legal compliance and fines. Concluding Thoughts There is little doubt that thoughtfully and purposefully constructing a service delivery strategy that leverages the strengths of contingent workers can lead to better projects, deliverables, and business results. What requires a bit more thinking is determining the platform (or platforms) that will enable each part of your organization to best deliver on its mission.

  • Software developer needs Validation for VA Chap 31 to purchase Macbook Pro vs. PC [closed]

    - by David
    I am currently attending college with a path of software development and working towards my BS thanks to VA Chap 31. My old original Macbook Pro is near dead and no longer upgradable on the software or hardware side. The VA has offered to purchase a PC laptop for me (Because my syllabi says computer required), but I do not want to go backwards. I have a lot invested in OS X software and Mac peripherals, not to mention I prefer to program in an Apple environment. PC vs. Mac costs are so drastically different that I must validate my request for a new Macbook Pro. In my request to the VA, I stated the above and some other topics but they requested more validation. Can anyone recommend issues, reasons, etc. to help me validate this purchase by the VA for school? Thanks in advance for your help, David
