To have Hibernate Spatial use this provider, simply drop
the jar on the class-path alongside the
hibernate-spatial.jar. When the Hibernate Spatial
library is loaded it will find the provider and use it
to retrieve the Hibernate dialect for Postgresql with
the Postgis extension. This dialect is a subclass of
org.hibernate.dialect.PostgreSQLDialect
With the provider installed, you can use it by setting the dialect in the Hibernate configuration file as in the following snippet.
... <property name="hibernate.dialect"> org.hibernatespatial.postgis.PostgisDialect </property> ...
When there is more than one Hibernate Spatial provider on the Class-Path, you should explicitly label the dialect for the Geometry valued properties.
... <property name="geometry" type="org.hibernatespatial.GeometryUserType"> <column name="geom" /> <param name="dialect">postgis</param> </property> ...
