Hello Cory,
thank you for your answer. First to say you were right, I had to explain
my problem properly. I was using the tutorial of geotools: "Coordinate
Transformation Services for Geotools 2.0" and I couldn't set the
CoordinateSystemEPSGFactory preferences. If you have access to an EPSG
database you can use it to make different important operations in your
WCTS (Web Coordinate Transformation System). CoordinateSystemEPSGFactory
uses an ODBC data source by default so I needed to develope my service
with a postgreSQL DB and I didn't get the correct way to modify the
initial preferences I said before. There is another point in the same
tutorial, it says: "A CoordinateSystemFactory can be created by giving
your connection and driver to the CoordinateSystemModifiedEPSGFactory
constructor" my problem started 'cause I had not any example at all in
this field and didn't know how to use that constructor correctly.
Finally I could figure out the problem (Yessssss!!!Now I'm happy!!!).
I'm sending the code source, I hope it can be useful for other
geotools-mates :-) Here it goes:
Class.forName("org.postgresql.Driver") ;
Connection conn = DriverManager.getConnection(
"jdbc:postgresql://localhost:5432/EPSG", "postgres","postgres") ;
CoordinateSystemModifiedEPSGFactory epsgBD= new
CoordinateSystemModifiedEPSGFactory(CoordinateSystemFactory.getDefault(),conn);
Cheers!
