 Post subject: Implement UserType methods depending on Dialect

Hello everybody...

I'd like to be able to switch behaviour of a UserType depeding on the dialect of the enclosing SessionFactory.

Is this possible at all?

How can I do that?

To be more specific:

I have a UserType that maps Strings to Oracle's FIXED_CHAR. I cannot use mapping files using that UserType on a HSQLDB because the FIXED_CHAR is unknown to HSQLDB. I could use VARCHAR as a fall-back, but how can I know if the UserType is used in a HSQLDB context or in a Oracle context?

Martin.

Or use a ParameterizedUserType and provided it some appropriate parameterization info...

Perhaps I am missing something obvious, but how do I find the Configuration from UserType?

You need the instance of org.hibernate.cfg.Configuration.
You will have loaded it when you started you application.
It basically is created loading the hibernace.cfg.xml.
We do it like this:

Code:
Configuration cfg = new Configuration();
URL url = new URL(hibCfgUrl);
cfg.configure(url);


Perhaps there are other ways.

you set own Configuration when start hibernate (for example in HibernateUtil) and call with static method

I do it with

HibenrateUtil.getConfiguration()
