I've resolved the problem
I want publish it, hoping it helps anyone.
I'm using Jdk 1.5 and geotools 2.2.
This is the right code:

tsArch.setHalo(sb.createHalo(Color.WHITE, 1, 2));

archStyle.
addFeatureTypeStyle(sb.createFeatureTypeStyle(null, archRule));
// ... restricted area style
PolygonSymbolizer restrictedSymb =

// Build the map
final MapContext map = new

map.getLayerBounds();
map.addLayer

map.addLayer

map.addLayer

map.addLayer(fsBugs,

map.addLayer(fsArch, archStyle);
/* Show
the map */
JFrame frame = new JFrame();
frame.setTitle

frame.setDefaultCloseOperation
(WindowConstants.EXIT_ON_CLOSE);
frame.setSize(640, 480);
JMapPane mapPane = new JMapPane();
com.
vividsolutions.jts.geom.Envelope env = new Envelope() {
{
for
(int i = 0; i < map.getLayers().length; i++) {
MapLayer mapLayer =
map.getLayer(i);
expandToInclude(mapLayer.getFeatureSource().

}
};
mapPane.
setMapArea(env);
GTRenderer renderer;
renderer
= new StreamingRenderer();
mapPane.setRenderer(renderer);
mapPane.setContext(map);
frame.
getContentPane().add(mapPane,BorderLayout.CENTER);
frame.
getContentPane().doLayout();
frame.getContentPane().setVisible
(true);
frame.show();
}
}
Now It run perfectly and show
me the map!!!!!
:)
I Hope it helps anyone.

Problem using "SpearfishSample using PostGIS"
Hi to all,
I'm
newbie in geotools and i'm trying to run the
"SpearfishSample using
PostGIS"
http://geotools.codehaus.
org/How+to+use+a+PostGISDataStore
I've followed the description steps
in the Html page.
I've created
the PostGIS database with the spearfish
data
(by The attached file
spearfish_data_pg.sql.zip that contains
all of the sample data as
zipped SQL insert statements.)
BUT
It doesn't work properly and give
me the following output:
'9-nov-2006
11.54.11 org.geotools.data.db2.
DB2DataStoreFactory isAvailable
INFO: DB2 driver found: false'

Using Tomcat but need to do more? Need to support web services, security?
