[udig-devel] new not existing shapefile opened for reading

[Jody Garnett]

Hello andrea, lets see if we can help. First of all what version of udig 
are you using? Shapefile got a lot of attention on trunk and we may of 
introduced a bug...it looks like you are using the createNewDataStore 
method so you are doing it right. I am available on the IRC channel if 
needed; and please let me know which version you are using. The 
tutorials folder has an example of writing a shapefile that you can run 
if needed.

I *have* had some problem with file.toURI() vs file.toURL().toURI() 
previously - perhaps that is it?
