[udig-devel] Error: java.lang.NoClassDefFoundError: org/geotools/data/sh

[Wouaco <wouaco@xxxxxxx>]

Hi there,

I'm french student working on uDig, trying to create a drag'n'drop 
plugin that allows user to drop icon on a map and display it.

I had some precious advices from Michelle S. Bachler, who succeded in 
creating such a plugin, so I could have the drop action creating a 
shapefile, a layer and adding it to the layer view.
But when the layer is added to the view, its icon displays with a red 
cross on it, and i get an error message in uDig status bar :

java.lang.NoClassDefFoundError: 
org/geotools/data/shapefile/indexed/RecordNumberTracker

If someone can helps me understand what causes the error, or even fix, I 
would be grateful.

Julien.
