Hi Michael,
Thanks for reply. Gustavo helps me to solve the problem. Basically he
changed the place where layer was added and takes the bounds from
MapContext, as follow:
try {
Style shpStyle = SLD.createPolygonStyle(Color.YELLOW, null,
0.0f);
FileDataStore dataStore = FileDataStoreFinder.getDataStore(new
File("/home/mesquita/shapes/Municipios.shp"));
SimpleFeatureSource shapefileSource =
dataStore.getFeatureSource();
final MapContext map = new DefaultMapContext();
map.addLayer(shapefileSource, shpStyle);
ReferencedEnvelope envelope = new
ReferencedEnvelope(map.getLayerBounds(),
map.getCoordinateReferenceSystem());
map.setAreaOfInterest(envelope);
saveImage(map, "/home/mesquita/image.jpg");
}
catch (IOException ex) {
Logger.getLogger(Teste.class.getName()).log(Level.SEVERE,
null, ex);
}
Now, I am facing another problem: generate a SVG file. I run the sample code
and the SVG generated has 0 bytes =(.
Anyone know how to fix it?

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
