[Geotools-gt2-users] Spearfish demo

[David A. <da...@ri...>]

Has anyone succeeded in running the Spearfish demo lately?  I'm using GT 2.1RC1

When I tried LiteRenderStyledMapPane instead of SytledMapPane, it had 
problems because
the DefaultMapContext coordinate reference system is WGS84 and the
Spearfish data coordinate reference system is UTM zone 13N.  There
doesn't appear to be any way to change the coordinate reference system
in DefaultMapContext.  Should this be possible?

I created a subclass of DefaultMapContext and set the coordinate reference
system to UTM zone 13N.  It was then possible to display a map when the
text symbolizer creation was removed.

The current code fails with the error shown below.  This isn't surprising 
as the
called function unconditionally throws an exception.  Is there some other
straightforward way to create a text symbolizer?

         TextSymbolizer tsArch = sb.createTextSymbolizer(Color.BLACK, font, 
"CAT_DESC");


org.geotools.filter.IllegalFilterException: Attribute: CAT_DESC is not in 
stated schema .

     public void setAttributePath(String attPath) throws 
IllegalFilterException {

                 throw new IllegalFilterException(
                     "Attribute: " +attPath+ " is not in stated schema "+".");
     }
