I am using Hibernate + JPA as my ORM solution. I am using HSQL for unit testing and PostgreSQL as the real database. I want to be able to use Postgres's native UUID type with Hibernate, and use the UUID in its String representation with HSQL for unit testing (since HSQL does not have a UUID type). I am using a persistence XML with dif...
Resolution: No I'm no longer extending the original parent. Original: Is there a way to annotate an inherited final setter method?

I have made an application using Java/Hibernate/MySQL, but whenever I try running it, it complains that the table for one of my entity classes has not been created. After some trial and error, I have come to the conclusion that the problem is coming from the way I am mapping embedded components, but I do not know how I may fix it. Here...
I'm not really sure how annotations actually work. I'm using JAXB and JPA (with eclipselink) on the same classes, i. e. I get class definitions like this: @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "Channel") @Entity public class Channel extends NamedEntity { @XmlAttribute @XmlSchemaType(name = "anyURI") @Column(n...

At the moment I am developing an annotation-based binding-framework for Java Swing that uses JGoodies Binding under the hood. Unfortunately I am stuck with an annotation for a JRadioButton-binding. What I want to do is specify a property-name of a model which holds a special value (enum). The radio-button shall be selected if this proper...
Try to write: List<Object> list; @SuppressWarnings("unchecked") list = (List<Object>) new Object(); It will fail on the 3rd line, on the word list, with the following: list cannot be resolved to a type I understand that it is related to how annotations work. Anybody knows the reasoning behind this? EDIT: thanks for the fast answer....

Is there a way to annotate a method so all exceptions thrown are converted to runtime exception automagically? @MagicAnnotation // no throws clause! void foo() { throw new Exception("bar")' } ...
I am writing some tools for our build system to enforce some strict calling conventions on methods belonging to classes containing certain annotations. I'm using the Compiler Tree API... What i'm wondering is when traversing the 'tree', how can you tell the type of class/interface for a MethodInvocation. I'm subclassing TreePathScan...

We are currently discussing the Best Practice for placing the @Transactional annotations in our code. Do you place the @Transactional in the DAO classes and/or their methods or is it better to annotate the Service classed which are calling using the DAO objects? Or does it make sense to annotate both "layers"? ...

Hello, I am using annotations to map a basic collection of Strings to an existing entity like this: Inside the parent entity class: @org.hibernate.annotations.CollectionOfElements @JoinTable (name="GoalToAchieve_entry", joinColumns=@JoinColumn(name="goalToAchieve_id")) @org.hibernate.annotations.Sort(type = org.hibernate.annotations.S...
Hello Everyone When I look at Java frameworks like Hibernate, JPA, or Spring, I usually have the possibility to make my configuration via an xml-file or put annotations directly in my classes. I am cosistently asking myself what way should I go. When I use annotations, I have the class and its configuration together but with an xml I ...
I accidentally left an extra comma at the end of one of my annotation lists, but it compiled fine on my machine. For example: @NamedQueries({ @NamedQuery(name="name1",query="FROM Foo"), @NamedQuery(name="name2",query="FROM Bar"), }) Notice the extra comma after the second @NamedQuery. It seems to compile fine on my ...
Hi all, I realise that this might be a question that has been asked and answered, but please bear with me. I want to know if it is possible to use annotations to inject code into your classes compile time. The classic example is to generate a getter and setter for the members of your object. This is not exactly what I need it for, but ...
