[Geotools-gt2-users] Things to remember for adding a new projection in geotools

[Rahul... हम पंछी उन्मुक्त ग. के <rah...@gm...>]

*add the projection provider entry in *
*
\modules\library\referencing\src\main\resources\META-INF\services\org.geotools.referencing.operation.MathTransformProvider.

Only extending the MapProjection won't work.

Sorry I forgot to mention that.. ;-( .. Actually earlier I was trying to
build the snapshot code from GT-referencing M1, may be therefore I was
getting errors at runtime. But when I builts the latest code from SVN, it
was working. Thanks again for your help. Now I will try to add a new
projection to it.
