The EPSG database is available in MS-Access format. Installing this database is the recommanded way to get the EPSG factory running. You don't need the MS-Access software; only the ODBC driver for MS-Access is required, and this driver is usually bundled with all Windows installation. Steps to follow:
Download the MS-Access EPSG database from http://www.epsg.org
and copy the EPSG_v6.mdb anywhere in yours file system. You can rename it at yours
convenience.
Open the ODBC data sources dialog box from the Windows's Control Panel.
Click the Add... button and select Microsoft Access Driver (*.mdb).
In the Data source field, enter EPSG.
Click on the Select... button and select yours (potentially renamed)
EPSG_v6.mdb file.
Make sure that the JAR file from plugin/epsg-access (which contains only the
AccessDataSource class and its META-INF/services/ registration)
is in yours classpath.
