Dear all,
I tried the example below:

http://svn.osgeo.org/geotools/trunk/demo/example/src/main/java/org/geotools/demo/SelectionLab.java

and rewrote it to load shapefiles from an URL on the web (thanks to Ian 
Turton). What I get is what I want except the map is flashing when the JMapPane 
is repainted. The flashing is taking longer for the maps that get their data 
from the web, compared to loading the data from the local harddisk, so it seems 
that it is not only a problem of the repaint() method but of the remote 
location of the files. How could I circumvent this flashing? Maybe by having a 
background map that is not repainted - just the "selection layer"? Or is it 
possible to use the DoubleBuffer mechanism in this case to avoid the flashing?

Regards and thanks for all the help
Jan
