I am installing a new version of Java on a CentOS/RHEL Linux distro for a single developer to develop java.
The way I want to install on this development system is to just put the new java version somewhere and then update my path so that the new java is earlier on the path (and thus executes always) instead of the old version of java (which will be later on the path).
But while looking online I came across an official multi-page howto for this distro... and it describes a completely different idea of what I SHOULD do: http://wiki.centos.org/HowTos/JavaOnCentOS
For a single developer, is modifying the path (to point to the new java) going to work for developing java?
Why would you ever want to go through the laborious description seen on the above referenced official wiki page?
