Hi all,
I'm developing simple web application focused on reference system 
transformations (see http://gist.fsv.cvut.cz:8080/webref/ ). For CRS 
transformation I'm using something like this:
  CoordinateReferenceSystem sourceCRS = CRS.decode(-source EPSG code-);
  CoordinateReferenceSystem targetCRS = CRS.decode(-target EPSG code-);        
  MathTransform transform = CRS.findMathTransform(sourceCRS, targetCRS);

I would like to ask few questions about using epsg hsql/wkt plugins (trunk 
version). 

1- It is very often that the OperationNotFoundException: Bursa wolf parameters 
required' is thrown.  Would you mind if I  commit (on trunk wkt-plugin) these 
Bursa Wolf parameters for few systems that we are using (here in Czech rep.)? 
Is it also possible  to ignore this and use zero shifts when this occurs?

2- There is a difference between the epsg-wkt and epsg-hsql – When I call 
EPSG 2065 CRS – wkt plugins finds CRS with Krovak projection (that is 
OK), but when using hsql plugin I'm getting  
org.opengis.referencing.NoSuchIdentifierException: No transform for 
classification "Krovak Oblique Conic Conformal". So do I have to add this alias 
for Krovak projection into the referencing module, or is it problem in 
hsql-plugin? 

Finally I have to say that referencing package plus epsg plugins are very 
helpful ! My boss was quite happy and surprised how fast and easy  it was to 
implement this web app. Thank you!

 Cheers,
Jan.
