Subject Re: Eclipse ClassNotFoundException

I wonder if the name of the annotator might be an issue.  In general, a class
name cannot have "." (periods) as part of the name - those are used to refer to
the package name, and the package name parts are set up as hierarchically nested
folders (each part corresponding to a segment of the name between periods
(except for the last segment which is the class name).

If that's not the issue, another thing to check is whether or not the classpath
for the project has been set up.  The Component Descriptor Editor makes the
assumption that the place where you're defining the descriptor is an Eclipse
project, which has a "build path" (eclipse terminology) set up to include the
annotator class.
