Hi Laura, at a first glance it seems to be just a problem of class name
clashing between java.awt.Polygon and com.vividsolutions.geom.Polygon.
Explanation:
it seems you have an import statement for java.awt.Polygon and thus the line:
> AttributeTypeFactory.newAttributeType("the_geom", Polygon.class);
is creating a simple attribute type bound to a java.awt.Polygon instead of a
GeometryAttributeType bound to com.vividsolutions.geom.Polygon,
So I'd suggest to just change that line to
> AttributeTypeFactory.newAttributeType("the_geom",
com.vividsolutions.geom.Polygon.class);
lets see if that helps and feel free to keep asking questions as needed.
Regards,
Gabriel.
