I've install jdk now with this reference. According to that I have to add jdk directory to PATH variable and add an alternative via
update-alternatives. I've done that and everything is fine. But there is one thing that is not clear for me: when I type
which java bash returns only
/usr/bin/java but tells nothing about
usr/bin/jvm/java-6-oracle/bin despite this folder is in the PATH variable and as I see, bash should have find
java also there and mention it in the output. Can anybody explain why there's such a "shade"?
