I had the need the other day to use the projection 3785 in uDig.  The 
current version of the epsg-hsql jar didn't support this projection code 
so I went digging.

In the epsg-hsql I found Martin's instructions for updating the EPSG.sql 
file.  So I followed these instructions and created a new EPSG.sql for 
my use.

1) I downloaded the latest EPSG database (Version 6.18) from 
http://www.epsg.org/.
2) I followed Martin's instructions for creating EPSG.sql database file.
3) I added a test case to the test cases to see if would read this 
projection from my new file.  Here I found a minor problem with this 
projection.  Apparently GeoTools doesn't support 'Mercator (1SP) 
(Spherical)' operation method; so I updated the EPSG.sql file to use 
'Mercator (1SP)'.  I'm not sure if there is a difference between these 
two, however it seemed to work for me.
4) I created myself a new epsg-hsql jar using this new EPSQ.sql file and 
I was able to use the 3785 projection in uDig.

If the community is interested I can provide this new EPSG.sql file & 
other modifications to the code (test case & version number updates) as 
a patch.
