I'm having a problem getting Geometry Points of type com.vividsolutions.jts.geo.Point and com.vividsolutions.jts.geo.Polygon using hibernate from my postgres database. I've tried a couple of different things and all have failed. Not sure if it has anything to do with it but my database stores the geometry datatypes as a long string of characters example of querying table for just this field:

track_position geometry(PointZ,4326) 010100000A0E6100000000000000000000000000000000000000000000000000000

In my java class for this table I have tried making the type a com.vividsolutions.jts.geo.Point com.vividsolutions.jts.geo.Geometry org.postgis.Geometry

When I run my query using both com.vividsolutions.jts.geo.Point and com.vividsolutions.jts.geo.Geometry Its able to parse the datatype and store it in my .java class However the value represented in the datatype shows up as Point( 0 0) and while debugging It shows 1 coordinate thats of type double and value of NaN which I understand to mean Not a Number.

When I change the datatype to type org.postgis.Geometry it fails to associate the two types and I get the following stack trace.

I'm assuming the datatype should be com.vividsolutions.jts.geo.Point since thats what the query returns but I need to figure how to actually make it so it gets the value from the database. Any help is greatly appreciated.
