I am trying to finds a way to install the Java SDK (javac) on Scientific Linux 64bit with yum or anyway.. Can someone please tell me the best what to do this so I can use maven for my builds etc
Just download the SDK from Oracle, place it in a suitable directory like /opt/java.
chmod it, i.e.:
unpack it, i.e.:
symlink it, i.e.:
set environment variables in /etc/profile.d/java.sh, e.g. (for ant but you get the idea):
Another option is to install the openjdk available via the distribution.
