Hi, We have a DB table that is mapped into a hibernate entity. So far everything goes well... However what we want is to only map enentitys that satisty a specific criteria, like ' distinct(fieldA,fieldB) '... Is it possible to map with hibernate and hibernate annotations? How can we do it? With @Filter? ...
My team is moving to Spring 3.0 and there are some people who want to start moving everything into Annotations. I just get a really bad feeling in my gut (code smell?) when I see a class that has methods like this: (just an example - not all real annotations) @Transaction @Method("GET") @PathElement("time") @PathElement("date") @Autowi...
Uri's answer got me thinking about what limitations JUnit 4 aquired by using annotations instead of a specific class hierarchy and interfaces the way JUnit 3 and earlier did. I'm wondering what limitations Annotations gave other people in using JUnit 4? One for me was the difficulty in creating a suite of dynamically generated classes. ...
I'm trying to find a way to check my classes for references of methods with a particular annotation (think "Deprecated"). As far as i see it, analysing byte code won't work because it doesn't contain any annotations. Using APT doesn't really help because i need the references to the methods, not the annotated methods themselves. So, wh...
I've got several MKAnnotationView red push pins on a MKMapView in my iPhone application on several locations. I'd like to implement a search bar that can move the map region to show these pins. How can I do this? Alternatively, the area I'm concerned about already has text labels built into the google map, so I'm wondering if there's a ...
So, for the past few days I have been struggling to understand how to implement a simple MKMapView with some custom annotations without crashing my application in the process. Unfortunately I have been unable to determine what I'm doing wrong and am becoming increasingly frustrated in the process. What I'm trying to accomplish should be...
I have the following inheritance hierarchy. @Entity @Table(FRUIT) @Inheritance(strategy=InheritanceType.SINGLE_TABLE) @DiscriminatorColum(name="FRUIT_TYPE",discriminatorType=STRING) public class Fruit { .. @Id private FruitId id; ... } @DiscriminatorValue("APPLE") public class Apple extends Fruit { ... @ManyToOne private FruitBowl bowl...
I believe the three below are syntactically correct; but which are permitted according to conventions (especially in the enterprise)? The first one below is used in most examples I've seen (e.g. JAXB), but it's verbose: <xs:annotation> <xs:appinfo> <myinfo>don't panic</myinfo> </xs:appinfo> </xs:annotation> This second one ...
Hi ! Am trying to create an object using an AOP framework which uses CGLIB to create proxy objects. Strangely enough, the "enhanced" proxy object is devoid of ANY annotations the previous class had! Can anyone tell me how can I make CGLIB retain the annotations on the proxies it creates? Cheers! Nirav ...
I have annotations on a mapview and a callout with a button on each. What I need to do is grab properties from this callout, ie. the title, but logging this line: NSLog(@"%@", mapView.selectedAnnotations); returns <AddressAnnotation: 0x1bdc60> which obviously gives me no useful info... My question is, how can I access the properties ...
Sorry my poor english! I'm trying to use the data annotation validators to make my validation server-side, I'm driving through this tutorial asp.net site: http://www.asp.net/learn/mvc/tutorial-39-cs.aspx, but is giving error in the time I put the attributes [Required], [StringLength (10)], etc., that because I'm using vb.net. When I cre...
Hi, I'm relatively new to hibernate and was wondering if someone could help me out. While I have no issues implementing a normal join on multiple columns in hibernate using the @JoinColumns tag, I'm stumped when trying to implement the following query in annotations: SELECT A.* FROM TABLEA A LEFT OUTER JOIN TABLEB B ON A.UID = B.ID AND...
Any ideas on how I could add type annotation to fix this error? I'm getting a red squiggly under Foo.Bar in getFooBar and the following error message for it. Lookup on object of indeterminate type based on information prior to this program point. A type annotation may be needed prior to this program point to constrain the type of the o...
I ran some DDL script to setup a complete country table in my database. The country table's primary key column contains the corresponding ISO code for every country. In my JPA project I have a User entity having an embedded Address entity and this Address entity has a reference to a Country. The relationship between User and Address se...
Hi, What is the best practice on implementing a transaction restart upon deadlock or lock timeout exceptions when using Spring (specifically the Spring recommended approach: declarative transactions) ? Thanks, Asaf ...
Entity A and B have a many to many relationship using link table AtoB. If Entity A is deleted, the related links are deleted by hibernate. So far so good. My problem is that my link table is a view hiding a much more complicated relationship and works perfectly in this situation except when hiberate tries to delete the link rows from t...
I am working on simple form to validate fields like this one. public class Contact { @NotNull @Max(64) @Size(max=64) private String name; @NotNull @Email @Size(min=4) private String mail; @NotNull @Size(max=300) private String text; } I provide getter and setters hibernate dependencies ...
Hi, I created a small desktop project using Hibernate, to understand how enterprise patterns are applied in there. I'm using annotations, and wrote a class to wrap my session factory public class Hibernation { private static final SessionFactory sessionFactory; static{ try{ //sesionFactory = new org.hibernate.cfg....
