[udig-devel] CRS not recognized in customized dataStore

[Jesse Eichar]

What does the layer report when you you look at the properties of your  
layer.  Is there a CRS  defined?  If not then most likely there is a  
problem obtaining the CRS from your service.  Another test you can  
perform is to set the layer CRS manually and then try repojecting and  
see if that solves your problem.  If that is the case then

1.  The service is not reporting the CRS correctly or
2.  The features are not reporting the CRS correctly in their default  
geometry.
