Hi Don
Found It!! And suitably embarrassed I am too!.
Ok , I am using Eclipse IDE to develop my code and it would seem that the project needs "refreshing" when ever there is an addition or amendment to any files within the classpath. So any new files (My new .shp files) need to be added by refreshing the project.
I thought that if the classpath was set in the project, then it would always search the physical directory .. Not the case it would seem
Sorry to have caused you grief!
Regards
Mark.

That's because we don't have a dcwpo_browse.shx or dcwpo_browse.dbf
file, and ArcExplorer needs those.

No.
The error message you are seeing is a result of the ShapeLayer
(actually, the SpatialIndex object) finding out that either the .shp
or .ssx file doesn't exist in a way that it can get to it.
This isn't a read problem, this is a location problem.
