Hibernate Forms

["Kuhns, John" <jk...@AimNTLS.com>]

I'd like to use Hibernate forms, but can't seem to find any good examples o= nline. In particular, I'd like to use my own configuration, and I can't see= m to find anything that works/makes sense. I need to use a custom naming st= rategy. Can anyone give me a few pointers?



Thanks,

Hi John,

You can use the SessionFilter[1] to create a thread local SessionContext[2] each request. The 
SessionContext is automatically configured via a hibernate.cfg.xml file on the classpath. I haven't 
used Hibernate in a while so not sure if you can configure a naming strategy in the 
hibernate.cfg.xml or through System properties. If not, you can implement your own SessionContext 
subclass for custom configuration. For example:

public class MySessionContext extends SessionContext {
   public Configuration createConfiguration() {
     Configuration config = new Configuration();
     config.setNamingStrategy(...);
     return config;
}

and setup the custom context in a filter:

public class MySessionFilter extends SessionFilter {

   public void init(FilterConfig filterConfig) throws ServletException {
     MySessionContext context = new MySessionContext();
     context.onInit(filterConfig.getServletContext());
   }
}

Its worth noting that HibernateForm uses SessionContext to lookup its Session and SessionFactory. So 
you don't need to use Click's SessionFilter/SessionContext to use HibernateForm, however you will 
need to override the HibernateForm methods getSession and getSessionFactory to lookup these objects 
when using an alternative session creation strategy.

Hope this helps.

kind regards

bob
