hello every body,
I am currently developing an application in Eclipse with geotools.
when I run the class WMS
it gives me this error:[Échec lors de l'initialisation d'un service de
catégorie "MathTransformProvider". La cause est "NoClassDefFoundError:
javax/media/jai/WarpAffine"].
the code class is :
import java.awt.image.BufferedImage;
