We are running geotools code from eclipse plugin land.
One thing we did was make a single plugin called libs and included all=20
the opensource jars in this one plugin, this makes sure they are in the=20
same classloader.

Eclipse keeps each plugin is a separate class loader and figures out who=20
can see whom based on dependency.  If you have the same jar in different=20
plugins the actual class files will be from different class loaders and=20
thus will not be able to be cast to each other.

Not sure if this information helps, but what the heck.

Our libs plugin is available for svn checkout here:
- http://svn.geotools.org/udig/trunk/plugins/net.refractions.udig.libs/

It is LGPL just like geotools so go ahead and use it in your project.
The externalToolBuilders and build.xml file are *magic* - they will=20
download the latest 2.1.x jars, either in your local maven repository,=20
or from the web.

To repeat the plugin needs to be "cleaned" once, it will then fetch all=20
the latest jars :-)
