Hi
I'm following the User Manual[1] to display a shapefile over a map. As
you can see I copy & paste the manual's example code but it doesn't work.
It fails with the following error:
--
PanelGeoMap.java:149: setWidth(org.geotools.filter.Expression) in
org.geotools.styling.Stroke cannot be applied to
(org.opengis.filter.expression.Literal)
symbolizer.getStroke().setWidth(filterFactory.literal(1));
PanelGeoMap.java:150: setColor(org.geotools.filter.Expression) in
org.geotools.styling.Stroke cannot be applied to
(org.opengis.filter.expression.Literal)
symbolizer.getStroke().setColor(filterFactory.literal(color));
2 errors

I've read the geotools and opengis javadocs[2] and I don't know how I can
fix the problem.
Any help will be appreciated. Thanks in advance.
