Just to follow up on this issue the instructions in the link provided by
Andrea work just fine (Thanks). I was able to add the 3785 projection
to uDig using the following code (and an epsg.properties file with the
definition of the projection):
Hints hints = new Hints(Hints.CRS_AUTHORITY_FACTORY,
PropertyAuthorityFactory.class);
ReferencingFactoryContainer referencingFactoryContainer =
ReferencingFactoryContainer.instance(hints);
PropertyAuthorityFactory factory = new PropertyAuthorityFactory(
referencingFactoryContainer,
Citations.fromName("EPSG"),
Activator.class.getClassLoader().getResource("epsg.properties").toURI().toURL());
ReferencingFactoryFinder.addAuthorityFactory(factory);
ReferencingFactoryFinder.scanForPlugins();
The key thing that took me a while to sort out was the last line
"ReferencingFactoryFinder.scanForPlugins()". Without this line it
doesn't work (at least it didn't work for me).

Interesting, thanks for the link. I don't know if this would work or
not. I never tried it; if I get the chance I'll look at let you know,
but I'm not sure I have the time at the moment.

Hi Emily,
I would guess that this works well for 1.1, but for uDig trunk we are
using
Yes exactly, I forgot while writing that it was that way.
BTW, I chose that method, since the methods added here:
http://docs.codehaus.org/display/GEOTDOC/11+Referencing+FAQ#11ReferencingFAQ-HowdoIextendthesystemwithmyowncustomCRS%3F
were not available in the old API. Any reason the above not working on
trunk?
I was planning to do that on trunk later on .
Ciao
Andrea
the hsql version of the epsg jar which doesn't seem to have
epsg.properties
file in it. Instead it has an EPSG.sql file which seems much harder to
understand :) However, this looks like it might be what I need to edit.
I'll play around with it and see if I can figure it out.
Thanks!

Hi Emily,
Yes, this is on uDig trunk.
I saw this page but it doesn't help me because neither 900913 or
3785 are
in
the geotools epsg-hsql jar (or at least I can't find them). I
don't know
how to add something to this jar for my local use; or add it somewhere
else.
I see the "Adding the Projection" section; but to what am I adding
that
insert statement?
Since I needed to do that for udig 1.1, I have solved it the way you
need it also.
Inside the epsg jar you will find an epsg.properties file. Inside
there the list of crs is kept, one per line:
epsgnumber=WKTdefinition
Make sure you have a unique number and add your definition.
What I do is substitute the original jar in the udig libs at the first
time JGrass is run. You might make a custom package so you probably
don't need that.
Ciao
Andrea
Thanks,
Emily

I hope this is udig trunk? The google projection now has an

I have a GeoWebCache layer in projection 900913. I'm trying to view
this
layer in uDig however uDig doesn't recognize the 900913 projection
(even
if
I add it as a custom CRS). Any ideas on how I can get uDig to
recognize
the
900913 projection - how can I add it to default list of projections
supported by uDig (either manually or programmatically)?
Thanks,
Emily
