1. Multiple HBM files with multiple classes for the same table    stackoverflow.com

Can you have 1 table be referred to by 2 different HBM's mapped to 2 different classes (they are unrelated, basic classes, no inheritance). I know it may be bad practice ...

4. Can't access generated java class from hbm2java    forum.hibernate.org

I configured my pom.xml so that it will use the hbm2java to generate a class source file from ./src/main/resources/com/brie/domain/Meeting.hbm.xml. Problem is, the generated file goes into the ./target/hibernate3/generated-sources/com/brie/domain/Meeting.java directory and I can't seem to access it from my program using it unless I manually copy it over into src/main/java/com/brie/domain. What is a good way to go about this? Below is my ...

5. hbm2java, build successful but generates no classes    forum.hibernate.org

Hi All, Knotty problem. Hope someone can help I'm using the ant (1.8.2) task hbm2java (hibernate3.jar) to create pojos. Works ok on my vista machine 1.8.1 and java 1.5, but when I run it on on my windows 7 box (ant 1.8.2/java 1.6), it runs through the script (with 'BUILD SUCCESSFUL') but does not create the required classes. Aside from the ...

6. hbm2java is overwriting a class file with an empty one.    forum.hibernate.org

We're using hbm2java to create class files. When I set up a particular mapping, one of the class files gets overwritten. Below, the file ValueObject.java that is created in the class mapping gets overwriten by a completely empty ValueObject.java. I'm assuming MapClass mapping is creating its own ValueObject.java. What am I doing wrong here? Code:

7. hbm2java is not creating my inner class    forum.hibernate.org

9. hbm2ddl generates tables for abstract classes    forum.hibernate.org

Forgive me if I've just totally missed this, but I did search around with no luck. I'm using the table-per-concrete-class inheritance scheme. I use hbm2java to generate both my concrete and abstract classes (the latter using the scope-class attribute). The code generation is working great, no problems! But.....hbm2ddl (SchemaExport) wants to generate "create table" statements for my Abstract Base classes no ...

With entity-name you can map the same class to multiple table (the thing that now differs is the entity-name instead of classname) I need to to split data into diffent tables of a legacy-system. Depending on the id of an object the mapping should be selecetd. e.g obj1 with id = 1000 has ...

12. Mapping an hbm.xml file with the generated classes properly    forum.hibernate.org

Newbie Joined: Thu Jun 17, 2004 4:16 pm Posts: 18 Hello all, How can I map the mapping hibernate files (*.hbm.xml) with the generated classes with my current project structure?

14. "table per class" in hbm    forum.hibernate.org

Hi, I want to take the "table per class" approach and am wondering if there's anyway to avoid the need to duplicate the common properties for every class (defined in a parent abstract class) definition in the hbm file. In our case we have a lastUpdateUser column in all of our tables, which won't be handled by a database trigger, because ...

15. Can hbm.xml files be separated from their classes?    forum.hibernate.org

Mapping files have no file-system relationship to the package at all. So long as the package attribute of the hibernate-mapping element is correct (it must be the package of the class file), then it will work. Some of the smaller projects in my company have chosen to put all mapping files together in one directory outside of the com.* package hierarchy. ...

16. Best Practices for generating classes from hbm.xml    forum.hibernate.org

I am working on a project where we are using the *.hbm.xml as the basis for both generating the classes and the schema and we have hit a point where we really want to add behavior to the generated (persistent) classes. Is there a best practice for this that either allows us to save modifications to the generated classes or to ...

19. Disable hbm2ddl for some mapping classes    forum.hibernate.org

Hello to everybody, I'm just trying to map a MySql - View with hibernate. It works fine, but there is still a little problem I would like to have fixed. The hbm2ddl.auto is set to 'update'. So hibernate wants to create the table (view) on server-startup and it brings out the following error messages in catalina.out: ERROR 2009-01-13 16:47:54,765 [main] org.hibernate.tool.hbm2ddl.SchemaUpdate ...
