I want to share a Hibernate configuration file across managed and unmanaged environemtns. In the managed environment I have access to a datasource but for the unmanaged environment, basic JDBC settings.

There are numerous ways I can approach this: -

- Use application clients and always use a datasoure
- Create filters in an ant file and generate a configuration file for each environment
- Create two configuration files (but then I would have to maintain both)

This would appear to be a very common requirement, sharing a Hibernate layer across environments. What approach are others taking?

Which configuration file? hibernate.cfg.xml or .properties ? Both are where, among other things, the JDBC URL or datasource settings are. This much will not be portable across a managed and unmanaged environments.

If you are trying to share the mapping configurations, one way is to jar them up and distribute it to both applications. Perhaps you could place the more portable configuration settings, such as show_sql=true, into a .properties and distribute this w/ the mappings as well.
