I've also looked into the installationguide but I feel kind of lost and don't know how to go on from here.
OS: Ubuntu 14.04 Trusty Tahr - 64bit
Java: java version "1.6.0_41" Java(TM) SE Runtime Environment (build 1.6.0_41-b02) Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01, mixed mode)
If any other information is needed, I'll be happy to provide it.
Thanks in advance!
