  • Struts2 JPA Validation error how to forward to action and not lose ActionErrors messages ?

    - by Sebastien Dionne
    I'm using Hibernate validator 4.1 to validate my entity. I have a dashboard that I can access from the action : viewDashboard. In my action, I load 2 List in my acion like this. public String execute() throws Exception { listDocteur = service.listDocteur(); listUser = service.listUser(); return SUCCESS; } In the DashBoard, I have a submit that can add a User. <action name="saveUser" class="com.test.action.CreateUserAction" method="execute" <interceptor-ref name="mybasicStackWithValidation" </interceptor-ref <result name="input"/WEB-INF/jsp/viewDashboard.jsp</result <result name="success" type="redirectAction"viewDashboard</result </action if I submit invalid value, I'll see the error messages, but I'll lose my 2 Lists. If I have a type="redirectAction".. I lose the error messages. in Struts 1, I would forward to the action viewDashboard.do without a redirect and that will works.. but How to do that in Struts2 ?

  • .Net 4.0 Is There a Business Layer "Technology" ?

    - by Ronny
    Hi, I have a theoretical question about the .net framework. As I see it Microsoft gave us bunch of technologies for different layers. We have the ADO.NET and with the more improved Entity Framework for Data Access. And ASP.NET for WEB UI. And even WCF for Facade and SOA. But what in the middle, what do we have for the Business Layer? Is it just Referenced DLLs? How do we deal with the Application Pulling this days? I remember using COM+ 10 yeas ago because the IIS couldn't handle the pressure. Is Spring.Net is the best option available for injection? Thanks, Ronny

  • Adding ivars to NSManagedObject subclass

    - by The Crazy Chimp
    When I create an entity using core data then generate a subclass of NSManagedObject from it I get the following output (in the .h): @class Foo; @interface Foo : NSManagedObject @property (nonatomic, retain) NSString *name; @property (nonatomic, retain) NSSet *otherValues; @end However, in my .m file I want to make use of the name and otherValues values. Normally I would simply create a couple of ivars and then add the properties for them as I required. That way I can access them in my .m file easily. In this situation would it be acceptable to do this? Would adding ivars to the .h (for name and otherValues) cause any unusual behaviour in the persistance & retrieval of objects?

  • Starting to construct a data access layer. Things to consider?

    - by Phil
    Our organisation uses inline sql. We have been tasked with providing a suitable data access layer and are weighing up the pro's and cons of which way to go... Datasets ADO.net Linq Entity framework Subsonic Other? Some tutorials and articles I have been using for reference: http://www.asp.net/(S(pdfrohu0ajmwt445fanvj2r3))/learn/data-access/tutorial-01-vb.aspx http://www.simple-talk.com/dotnet/.net-framework/designing-a-data-access-layer-in-linq-to-sql/ http://msdn.microsoft.com/en-us/magazine/cc188750.aspx http://msdn.microsoft.com/en-us/library/aa697427(VS.80).aspx http://www.subsonicproject.com/ I'm extremely torn, and finding it very difficult to make a decision on which way to go. Our site is a series of 2 internal portals and a public web site. We are using vs2008 sp1 and framework version 3.5. Please can you give me advise on what factors to consider and any pro's and cons you have faced with your data access layer. Thanks.

  • Migrating shape sql to something equally powerful

    - by daRoBBie
    Hi, we are currently investigating a migration of an application that doesn't meet company standards. The application is built using VB6 and Shape SQL/Access. The application has about 120 reports by storing Shape SQL strings in a database which the user can modify using a wizard. Shape sql is not allowed at this company. We have investigated plain SQL, Linq, Entity Framework as alternatives... but all result in more complex solutions. Does anyone have another suggestion? Update: Shape SQL is an ADO command to get hierarchical datasets, for further info: http://support.microsoft.com/kb/189657

  • Single Large v/s Multiple Small MySQL tables for storing Options

    - by Prasad
    Hi there, I'm aware of several question on this forum relating to this. But I'm not talking about splitting tables for the same entity (like user for example) Suppose I have a huge options table that stores list options like Gender, Marital Status, and many more domain specific groups with same structure. I plan to capture in a OPTIONS table. Another simple option is to have the field set as ENUM, but there are disadvantages of that as well. http://www.brandonsavage.net/why-you-should-replace-enum-with-something-else/ OPTIONS Table: option_id <will be referred instead of the name> name value group Query: select .. from options where group = '15' - Since this table is expected to be multi-tenant, the no of rows could grow drastically. - I believe splitting the tables instead of finding by the group would be easier to write & faster to execute. - or perhaps partitioning by the group or tenant? Pl suggest. Thanks

  • Extending LINQ classes to my own partial classes in different namespaces?

    - by sah302
    I have a .dbml file which of course contains the auto-generated classes based on my tables. I would however, like to extend them to my own classes. Typically I design such that each of my tables get their own namespace in their own folder containing all of their associated dao and service classes. So if I am dealing with a page that only has to do with 'customers' for instance, I can only include the customerNS. But when using LINQ I seem to be unable to do this. I have tried removing a default namespace from the project, I have tried putting the .dbml file into it's own folder with a custom namespace and then adding a 'using' statement, but no nothing works. I also saw the Entity Namespace, Context Namespace, and Custom Tool Namespace properties associated with the .dbml file and tried setting all these to names x and trying 'using x' in my other class to allow me to extend partial classes, but it just doesn't work. Is this possible or do I have to keep all extended partial classes in the same namespace as the .dbml file?

  • How do I set default values on new properties for existing entities after light weight core data migration?

    - by Moritz
    I've successfully completed light weight migration on my core data model. My custom entity Vehicle received a new property 'tirePressure' which is an optional property of type double with the default value 0.00. When 'old' Vehicles are fetched from the store (Vehicles that were created before the migration took place) the value for their 'tirePressure' property is nil. (Is that expected behavior?) So I thought: "No problem, I'll just do this in the Vehicle class:" - (void)awakeFromFetch { [super awakeFromFetch]; if (nil == self.tirePressure) { [self willChangeValueForKey:@"tirePressure"]; self.tirePressure = [NSNumber numberWithDouble:0.0]; [self didChangeValueForKey:@"tirePressure"]; } } Since "change processing is explicitly disabled around" awakeFromFetch I thought the calls to willChangeValueForKey and didChangeValueForKey would mark 'tirePresure' as dirty. But they don't. Every time these Vehicles are fetched from the store 'tirePressure' continues to be nil despite having saved the context.

  • Performance - User defined query / filter to search data

    - by Cagatay Kalan
    What is the best way to design a system where users can create their own criterias to search data ? By "design" i mean, data storage, data access layer and search structure. We will actually refactor an existing application which is written in C# and ASP .NET and we don't want to change the infrastructure. Our main issue is performance and we use MSSQL and DevExpress to build queries. Some queries run in 4-5 minutes and all the columns included in the queries have indexes. When i check queries, i see that DevExpress builds too many "exists" clauses and i'm not happy with that because i have doubts that some of these queries skip some indexes. What may be the alternatives to DevExpress? NHibernate or Entity Framework? Can we build dynamic criteria system and store these to database in both of them ? And also do we need any alternative storage like a lucene index or OLAP database?

  • Unicode and PHP - am I doing something wrong?

    - by alex
    I'm using Kohana 3, which has full support for Unicode. I have this as the first child of my <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> The Unicode character I am inserting into is é as in Café. However, I am getting the triangle with a ? (as in could not decode character). As far as I can tell in my own code, I am not doing any string manipulation on the text. In fact, I have placed the accent straight into a view's PHP file and it is still not working. I copied the character from this page: http://www.fileformat.info/info/unicode/char/00e9/index.htm I've only just started examining PHP's Unicode limitations, so I could be doing something horribly wrong. So, how do I display this character? Do I need to resort to the HTML entity?

  • Why is the C# SerializedAttribute is sealed?

    - by ahmet alp balkan
    I was trying to create an attribute that implies [Serializable] but I noticed that this SerializableAttribute class is sealed. In Java it was possible to create an interface (say, MyInterface) that is inherited from Serializable interface and so all the subclasses of MyInterface would also be serializable, even its sub-sub classes would be so. Let's say I am creating an ORM and I want customers to annotate their entity classes as [DatabaseEntity] but in order to make sure that entities are serializable, I also need to ask them to attribute their classes with extra [Serializable] which does not look quite compact and neat. I am wondering why SerializableAttribute class is sealed and why has Inherited=false which implies that subclasses of serializable class will not be serializable unless it is explicitly stated. What motives are behind these design choices?

  • Google analytics-style custom report builder UI

    - by gregmac
    I'm looking for a reporting engine/UI that can be integrated into a product, which has a UI along the lines of Google Analytics' Custom Reports builder. Is anyone aware of such a thing? The data is in our case is not page views/visitors/etc, but is similar in nature, in that there are limited entities or types of data, but each entity has many attributes/columns and many different ways of aggregating data (or in GA-style speak, metrics and dimensions). The analytics-style UI is very intuitive and allows many reports to be created in powerful ways, without having to know SQL. I have preference for a web-based tool (seeing that it is 2010 and this is a web app -- I mention only because it seems the vast majority of reporting tools still have only a non-web-based creation tool).

  • hibernate formula with column

    - by coolguy
    I have a table with a column that will be encrypted by a trigger after the record is inserted. When I read the column, I need to apply a decrypt function in the hibernate domain class. While saving the object, the value of the column will be saved as such. While reading the column, apply a database function on the read data. @Formula and @Column annotation cannot be applied to an attribute in the entity class. How do I achieve this functionality without using one attribute for saving and another one with @Formula for reading it?

  • How to retrieve Aggregate objects?

    - by Jebb
    In DDD, Repository takes care of saving and retrieving domain objects and also serves as collection of Aggregate Roots. My question is how do you retrieve the information for those child entities (let's say from DB) of an Aggregate where basic rule is Repository should just hold collection of Aggregate Roots (parent object) and not child objects? For example: User (parent object) Orders (child object) User domain object is stored in user table and Orders are stored in another table. Basically, retrieving a Domain Object could be like this: <?php $userRepos = new UserRepository(); $user = $userRepos->find($userId); ?> How then the child object (Orders) of User entity be retrieve to be as part of the User aggregate?

  • Seam Equivalent of Spring PersistenceUnitPostProcessor

    - by shipmaster
    We have a very comfortable setup using JPA through Spring/Hibernate, where we attach a PersistenceUnitPostProcessor to our entity manager factory, and this post processor takes a list of project names, scans the classpath for jars that contain that name, and adds those jar files for scanning for entities to the persistence unit, this is much more convenient than specifying in persistence.xml since it can take partial names and we added facilities for detecting the different classpath configurations when we are running in a war, a unit test, an ear, etc. Now, we are trying to replace Spring with Seam, and I cant find a facility to accomplish the same hooking mechanism. One Solution is to try and hook Seam through Spring, but this solution has other short-comings on our environment. So my question is: Can someone point me to such a facility in Seam if exists, or at least where in the code I should be looking if I am planning to patch Seam? Thanks.

  • How do I visualize a complex graph in .Net?

    - by Ivan
    I need to visualize a graph (technically being a set of Entity Framework objects, but I can translate it to another representation if needed) of this kind. I don't know how to name it (by the way, if you know - I'll appreciate if you tell me). It would be ideal for graph elements to be clickable (so that when user clicks on a block, I can handle an event with the element id specified) but I can survive even without any interactivity. Are there any components available good for this task? If no, what should I look for to help me to develop an algorithm for drawing such a graph with visually-comfortable layout?

  • database table in Magento does not exist: sales_flat_shipment_grid

    - by dene
    We're using Magento 1.4.0.1 and want to use an extension from a 3rd party developer. The extension does not work, because of a join to the table "sales_flat_shipment_grid": $collection = $model->getCollection()->join('sales/shipment_grid', 'increment_id=shipment', array('order_increment_id'=>'order_increment_id', 'shipping_name' =>'shipping_name'), null,'left'); Unfortunately this table does not exist n our database. So the error "Can't retrieve entity config: sales/shipment_grid" appears. If I comment this part out, the extension is working, but I guess, it does not proper work. Does anybody know something about this table? There are a backend-option for the catalog to use the "flat table" option, but this is only for the catalog. And the tables already exists, no matter which option is checked. Thank you a lot! :-)

  • A series of simple Aggregate Root questions (Domain Driven Design)

    - by Robert
    I have a few (hopefully) simple questions about aggregate roots in domain driven design: Is it okay to have an aggregate root as a property of another aggregate root? Is it okay to have a given entity inside two or more aggregate roots? My final question is a bit more involved. I have a website that has a few entities that really belong to a "website" aggregate root. They are 'News', 'Products', and 'Users'. There isn't a 'Website' table in the database, but a 'Website' seems like a good aggregate root for these three entities. How is this usually achieved? Thanks!

  • Is there a way to hide annotations in Netbeans or Eclipse?

    - by Boden
    Maybe a dumb question, but it would be nice if there was a way to hide or collapse Java annotations when viewing source in Netbeans (or Eclipse). I'm not finding an option and a quick search didn't turn anything up. Is this one of those "you should never want to do that, code folding is a sin!" things? Personally I'd find it useful for annotated entity classes. All the hibernate / etc annotations are just fluff that I never look at once my mapping is working fine. It's similar to imports, really. (Yes, I can use XML instead of annotations, which I might start doing. But I was just wondering...)
