[geotk] Re: trouble with jai-next

[sorel johann]

That's what I was expecting.

your shapefile do not define any projection.
le .prj file is missing.

What is happening, is that the shapefile do not define a projection, so 
when the renderer try to
find the best envelope it fails.
Geotools does not raise any error since it simply assume that if it's 
not defined it's a CRS:84.

try to add the appropriate prj file, it should solve the problem.
I'll fill improve the error message when I'll have a bit of time so that 
we know what's happening.
