[postgis-users] JAVA and post GIS

[Emily Gouge]

Hi,

There is some documentation and an example on connecting to PostGIS using Java.  See:
http://postgis.refractions.net/docs/ch04.html#id2789526

You can add a datatype to the postgres connection and then the getObject() call will return a 
PGGeometry object:
((org.postgresql.Connection)conn).addDataType("geometry","org.postgis.PGgeometry");

Additionally you can also check out the postgis_jts jar, which provides the ability to return a 
JtsGeometry object (and subsequently to convert this object to a JTS Geometry object).
