[mapserver-users] my mapscript generates blank map

[Ahmet Temiz]

with Following code, resulting map looks blank.

classObj c1 = new classObj(jeo_layer);
                            styleObj new_style = new styleObj(c1);
                            colorObj color = new colorObj(200,0,0,20);
                            new_style.setColor(color);
                            c1.setName("Eosen");
                            c1.setExpression(" \"yas=Eosen\" ");
                            c1.insertStyle(new_style, 0);
                            jeo_layer.insertClass(c1, 0);

jeo_layer.setStatus(1);
