Hi Sommer,
GeoServer falls back on support in the underlying GeoTools library for
all reprojection. The file you are looking for is inside the
gt2-epsg-wkt.jar located in the WEB-INF/lib directory of the server. Its
called epsg.properties. Its basically a mapping from EPSG code to the
WKT describing the coordinate system.

Hello,
As we do not have our data in a standard coordinate system (it is EPSG:31283 but with 5000000 subtracted in the y axis), I would like to know where GeoServer gets the definitions of coordinate system from, using the EPSG code. In proj4 this is a text file, but GeoTools seem to use a database (the access database from EPSG?), but I did not find any database in the installation. It seems to be possible to get the data from a postgreSQL database, which we already have loaded with EPSG data and which we could extent with a custom code definition.
Can anybody tell me, how this can be done?
Best Regards,
Gerhard
