Hi,
I am using GeoTools 2.5.0. I want to project data in another CRS to Google
Mercator CRS. I was previously using WKT to create the Google Mercator CRS.
Since now we have an official EPSG code for the same I want to switch over
to that. Please find below the code that I have written.
CRSAuthorityFactory factory = CRS.getAuthorityFactory(true);
CoordinateReferenceSystem crs =
factory.createCoordinateReferenceSystem("EPSG:3785");
The same code worked when I used EPSG:4326.
I have added gt-epsg-extension-2.5.0.jar to the classpath. Even after doing
so I get the following exception:
Exception in thread "main"
org.opengis.referencing.NoSuchAuthorityCodeException: No code "EPSG:3785"
from authority "European Petroleum Survey Group" found for object of type
"CoordinateReferenceSystem".

I had a similar error when I used EPSG:900913.
I referred to other posts and there was a mention that epsg-ext jar had to
be added to the classpath for this. I am assuming that the jar referred to
is gt-epsg-extension-2.5.0.jar. I have not configured any EPSG databases. On
checking the esri.properties file in gt-epsg-extension-2.5.0.jar, I could
not find an entry for 3785 and 900913.
Please let me know if I am missing something.
Thanks and Regards,
Shyam Sundar.N
