1. from Hibernate hbm to JPA annotations, a challenging one

@Inheritance(strategy ...

8. Replacing *.hbm.xml files with @Annotations.

I have three java classes that are persisted using hibernate. I want to switch from using *.hbm.xml files to annotations on these classes. However the db has additional tables that are created by tags in hbm.xml. Is there a way to create these extra tables using annotations without having to create additional java classes? One of the java classes that result ...

9. auto listener doesnt work for mixed annotation and .hbm.xml

We have kind of an odd environment where our domain model configuration is a mix of annotation and .hbm.xml files. What I noticed is that for entities having .hbm.xml configuration, auto indexing didnt work even with added post update listeners. I have two questions 1. Should we need listeners in such mixed environment? 2. What configuration might be missing which is ...

12. @Audited annotation in Hibernate hbm file

Is this a reverse engineering issue? Then this sounds like an issue for the Tools subforum. Short answer: You'll have to modify a template. You'll also have to signal the template whether to add that annotation or not, probably by adding a tag to the table in reveng.xml. The basic procedure isn't difficult, but the docs tend to get a ...

16. Annotations Vs HBM2Java

Hello, We are starting a new project under Hibernate, and we would like to know which way is the best or easiest to work with. 1) Use HBM XMLs to create/maintain schema & then feed these XMLs to Hbm2Java so that POJOs will be generated for us. Later extend these POJOs as necessary. OR 2) Use Java Annotations in the class ...

17. hbm2ddl and annotations

I think I just found the solution to your problem: you can convince hibernate to quote names in the generated SQL: Just use a mapping like .... (observe the backticks `) hibernate will then quote the name on SQL-generation, it will even choose the right quote-character for your SQL-Dialect.

18. hbm.xml vs. annotations

Currently, I have a class which contains a set of String objects from a child table. All of the examples that I've seen only show the xml version of this setup, and using the hbm.xml file, this is working just fine. I would like to move entirely to annotations, but haven't found an equivalent way of specifying which database column to ...

20. Using Hibernate Search without Annotations (using hbm.xml)?

I am working on a project, using the latest version of hibernate core and search. Is it possible to configure an entity for search (like, index a class) using the .hbm.xml files? If so, how? All the examples use the annotations like @Indexed or @Field ... I'd like to do it with hbm.xml files.

21. Can I generate annotations with hbm2java?

If i want to use hbm.xml files for everything, but want to use "hibernate search"... which as far as i can tell requires annotations... Can I generate annotations on my classes and properties? using @Indexed doesnt work because it puts the '@Indexed' part on the same line as the class declaration. Nobody is answering my other thread about not using ...

23. Moving from hbm to annotations memory issues

Hi, I have recently altered the mapping generation on a project from using Xdoclet and hbm to use annotations. However, on starting the Tomcat server where some of the data is cached we have a much larger memory footprint. The size is as follows using hbm size is approx 50MB using annotations the size is approx 170MB The data cached does ...

Hello I was wondering if all functional aspects provided by .hbm.xml mapping files were also supported by annotations I've written a quite complex source code with .hbm.xml mapping files which works perfectly well under hibernate 3.2.6 GA and entity-manager 3.3.2 GA and wanted to move to annotations things which seem to me a little bit awkward to guess from docs are ...
