Stefano,
Take a look in the adobe-livecycle-jboss.ear-contents folder that is currently deployed in your environment.
For example, on my turnkey JBoss LiveCycle 8.2 install, the ear contents are currently deployed at
C:\Adobe\LiveCycle8.2\jboss\server\all\tmp\deploy\tmp34412adobe-livecycle-jboss.ear-contents
