Bundle: 8

Bundle: 9

start 9
These bundles were signed by the core certificate and have
AllPermission
, so you
should see an empty paint program (one with no shapes) after starting the paint bun-
dle. Next, install and start the unsigned circle bundle:
->
install file:paint-example/circle-4.0.jar
Bundle: 10
->
start 10
Doing this causes the user to be prompted to grant the permission, as shown in fig-
ure 14.3. If you grant the bundle permission, you get a circle shape in the paint pro-
gram, as shown in figure 14.4.
