Steps for the HighScore Developer (Chris)
The steps Chris would take, after creating the
HighScorePermission classes, are:
Compile the Classes
javac HighScore*.java -d .
Place the class files in a JAR File
jar cvf hs.jar com/scoredev/scores/HighScore*.class
Create a Keystore and Keys for Signing
keytool -genkey -keystore chris.keystore -alias signJars
Specify whatever you want for the passwords and distinguished name information.
Sign the JAR File
jarsigner -keystore chris.keystore hs.jar signJars
Export the Public Key Certificate
keytool -export -keystore chris.keystore -alias signJars -file Chris.cer
Supply Files and Information Needed by Game Developers and Users
That is, supply them
- the signed JAR File
- the public key certificate file
- information as to the permissions the
HighScorePermissionclasses must be granted in a policy file in order to work. For this, Chris could supply the exact grant entry needed.
