[postgis-users] Hibernate with PostGIS

[Dave Potts]

First of all thank you Norman for writing the orginal code.

There is a slight problem with it, it does not handle a null geometry 
column, rewritting nullSafeGet as follows, fixes the problem.

I can not say if it will address Sandeep problems, but it is worth trying.

David.

        /**
         * @see 
org.hibernate.usertype.UserType#nullSafeGet(java.sql.ResultSet, 
java.lang.String[], java.lang.Object)
         */
        public Object nullSafeGet(ResultSet resultSet,
                      String[] names, Object owner) throws 
HibernateException, SQLException {
            Geometry result = null;
            String geom = resultSet.getString(names[0]);
            if(geom != null ) {
                BinaryParser parser = new BinaryParser();
                result = parser.parse(geom);
            }
            return result;
        }
