Please do not use gt-epsg-wkt and the epsg-hsql at the same time! If you 
check the wiki page here:
- http://docs.codehaus.org/display/GEOTDOC/07+Referencing

You will see that only one epsg "authority" should be used at a time: 
<http://docs.codehaus.org/display/GEOTDOC/07+Referencing>

You will find that using the epsg-hsql authority is much better; it 
makes use of the real EPSG database (instead of a text format that does 
not contain quite the same information).
