Steps for the ExampleGame Developer (Terry)

The steps Terry would take, after creating a game (ExampleGame ) that calls the HighScore getHighScore and setHighScore methods to get and set, respectively, the user's high scores, are:

Compile the Game Class

javac -classpath hs.jar -d .

Place its class file in a JAR File

jar cvf terry.jar com/gamedev/games/ExampleGame.class

Create a Keystore and Keys for Signing

keytool -genkey -keystore terry.keystore -alias signTJars

Specify whatever you want for the passwords and distinguished name information.

Sign the JAR File

jarsigner -keystore terry.keystore terry.jar signTJars

Export the Public Key Certificate

keytool -export -keystore terry.keystore
    -alias signTJars -file Terry.cer

Supply Files and Information Needed by Users

That is, supply them

Game users also need files and information from Chris. For their convenience, Terry may forward this information to them:
