Hibernate version: 3.x

Hello.

We have here several subproject, all subproject result in a .jar containing various classes and some .hbm.xml mapping files

Then we have other projects (let's call them main projects), which use those .jar. In those other projects, we need to load hibernate configuration, this include all *.hbm.xml files present in those jar.

Assuming all those .jar are in classpath (WEB-INF/lib), we could use lots of

in our hibernate.cfg.xml. But it's not very easy to manage. If there are changes in a subproject (eg, one additionnal class 'X'), we need to add a corresponding mapping tag to all main projects.

It would be interresting if there was some way to have hibernate do things like 'Ok, need to use class X, let's explore the classpath ressources to find it's mapping', but all i see is either list mappings in main config file, either do some addClass() in main projects.

Is there some way to have hibernate related changes in subprojects automatically reflected to main projects (just update the .jar and it's done)?

Hi tchize,

If you are using Spring to configure Hibernate, you can actually specify the jar that contains the mapping files, and it will find all the mapping files automatically. For example, my Spring configuration for Hibernate is:



Hope this help,

No sorry, we are not using Spring. Hibernate is configured by hibernate.cfg.xml in a HibernateSessionFactory.

Moreover, names of jar are not so predictable. The whole project is managed by maven, and they looks like

WEB-INF/lib/RMI-Hibernate-<subproject>.<subprojectVersion>.jar
