The capability bits don't modify the Appearance itself! They only say what can be modified after the object was compiled. To change the properties of your Appearance object, try the different get...() methods to access the Texture, Color, MaterialAttributes etc. (please refer http://java.sun.com/products/java- media/3D/forDevelopers/J3D_1_3_API/j3dapi/javax/media/j3d/Appearance.html for all methods which can be used for getting and setting the different values).

In your example a3 is a reference to a Appearance object which belongs to a object which seems to be live. And it is exactly like the error message says: you can't modify the capability bits of an object which is live.
Appearance a3 = new Appearance(); a3 = shape.getAppearance();
is a little bit senseles: You create a new Appearance a3 and overwrite it immediately afterwards. Modify the capability bits directly after the creation of your new Appearance object and everything should work fine.
