Steve Ebersole updated HHH-2933:
--------------------------------

         Assignee: Steve Ebersole
      Description: 
Introducing DialectResolver!

Much better approach to resolving JDBC Connection information to Dialect allowing users to define custom behavior

  was:
Currently the DialectFactory has the static attribute MAPPERS, that hold the dialects. If the dialect is not found, Hibernate will throw an exception. There is already an TODO tag, set for this.So, could this be possibly done, so that the values really are a) in a properties file or b)additions could be made to the map programmaticaly by users.

This would be more flexible for advanced users, that work with experimental jdbc drivers(that don't return a standard name for the database).

The current trunk version of DialectFactory:

// TODO : this is the stuff it'd be nice to move to a properties file or some other easily user-editable place
	private static final Map MAPPERS = new HashMap();
	static {
		MAPPERS.put( "HSQL Database Engine", new VersionInsensitiveMapper( "org.hibernate.dialect.HSQLDialect" ) );
		MAPPERS.put( "H2", new VersionInsensitiveMapper( "org.hibernate.dialect.H2Dialect" ) );
		MAPPERS.put( "MySQL", new VersionInsensitiveMapper( "org.hibernate.dialect.MySQLDialect" ) );
                etc.....


    Fix Version/s: 3.4
                   3.3.x
                   3.2.x
       Issue Type: Patch  (was: Improvement)
          Summary: externalize automatic resolution of Dialect (Tomoto Shimizu Washio)  (was: DialectFactory dialects should be in a properties file)
