You can find all the information you need about this topic on d.android.com: http://developer.android.com/tools/publishing/app-signing.html#signapp

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore
my_application.apk alias_name

One thing that cost me a few hours already, but is also mentioned in the official documentation:

As of JDK 7, the default signing algorithim has changed, requiring you to specify the signature and digest algorithims (-sigalg and -digestalg) when you sign an APK
