Hello. I am creating a new java application that works with databases, and I am considering using Hibernate.

This application must be "plugged" on a database using a configuration file. Explanation : it is going to be used by different customers, each with their own databases, probably with different models. I want to be able to adapt the application without changing the code, simply by changing a configuration file.

Does Hibernate supports this?

Different databases are usually no problem for hibernate (regarding to your implementation). This is configurable within a xml-config-file.

But how do you want to implement code for 'probably different' models? With hibernate you would need different mappings...and you 'probably' might want to use the (potentially unknown) attributes beforehand.

hibernate objects can be generated on the fly using the hbm2java program. This generates the POJOs from the mapping files for each class.

Thank, I am going to try to find information about hbm2java.
