[geotk] Loading of derby EPSG database - takes time

[Westgård Trond]

Hi,
In a NetBeans Platform application based on PuzzleGIS and geotoolkit, there is at the startup of the application (in an Installer for the module) this statement:

       //force loading/creating epsg database.
        try {
            CRS.decode("EPSG:3395"); // BOTTLENECK 14 % of startup
        } catch (Exception ex) {
            Exceptions.printStackTrace(ex);
        }

The first time the database containing the EPSG-codes and the coordinatesystem parameters is loaded from a resource in one of the geotoolkit's libraries and installed on the user's computer. Using the statement above each time the application starts it takes about one minute to do this operation.

Is there a way to check if the EPSG derby database is already installed on the user's computer and consequently spare some computer time ?
