To recreate P1.jar/P2.jar, although I doubt this will ever be necessary, do

the following.

mkdir classes

javac -d classes \

P1SecretKeyFactory.java Provider1.java \

P2SecretKeyFactory.java Provider2.java

cd classes

jar -cvf ../P1.jar com/p1

jar -cvf ../P2.jar com/p2

cd ..

rm -rf classes

jarsigner -keystore YourJCESigningKeyKeyStore.ks P1.jar yourKeySigningAlias

jarsigner -keystore YourJCESigningKeyKeyStore.ks P2.jar yourKeySigningAlias
