I'm trying to read and display a shape file. I modified the campusworld example 
(removed a couple of lines). The example still works but not with the file (and 
others) I've attached.
The roads of the UK should be displayed but the only thing I can see is the 
bounding shape.
Reading the same file with the freely available "ArcExplorer for Education in 
Java" displays the map as I expected.

Any idea what is wrong with the file or what I have to do to get the roads 

Best regards,
