[mapserver-users] JAVA Mapscript LayerObj issues

[julien]

Just to let people know, I found the solution.

I changed :
classObj my_class = new classObj(my_layer_item.layer_object);
styleObj my_style = new styleObj(my_class);

By :
classObj my_class =  my_layer_item.layer_object.getClass(0);
styleObj my_style = my_layer_item.layer_object.getClass(0).getStyle(0);
