Bundle the Applet

HotJava recognizes JAR files, which are created using the jar tool. Our applet contains only one file, so we can create the JAR using the following command:

jar -cf Renegade.jar Renegade.class

This takes Renegade.class and puts it in a new JAR called Renegade.jar.

Sign the Applet

We’ll use the javakey tool to sign the JAR, as described in Appendix D. The directive file should look like this:

signer=Marian cert=1 chain=0 signature.file=MARIANSG out.file=hjRenegade.jar

Save this in a file called MarianSign.directive. Then you can sign the JAR using the following command:

javakey -gs MarianSign.directive Renegade.jar

The JAR is signed with Marian’s private key, and the resulting signed JAR is hjRenegade.jar.
