How does JbossCache relate to JavaGroup??

Hello,
Forgive my naiveness but I am trying to ascertain what the difference is between JbossCache and JavaGroups.
Can anyone give me a clue?
Thanks in advance,
Julien

JBossCache is a transactional caching solution built on top of JGroups. JGroups is a reliable multicast toolkit.
