Adding Labels to a Vector Map with Java Mapscript

[Alejandro Rico]

Hi!!!

I try what you said, but the method setColor in classObj doesn't exist, then
i didn't modify the part of the style. However running the program it draws
the map with the same labels.

here's the mapfile and the map image.

thanks for your help !!!!!
