What I meant is that the instructions you suggested in your first e-mail
are taken from:
and are all but comprehenssive, let alone appropriate for beginners.
These installation instructions have been accompanying Sun Java as long
as I can remember, and "strangely", no one cared to mention 'em in the
Wiki page... don't you think that's kinda odd? I don't - 'cause they
This second part (editing /etc/profiles, deleting symlinks and editing
PATH...) is NOT what you mentioned in your first e-mail. However, in my
honest oppinion, this is still not the correct way to do this.
What you did, is that you probably got it to work for Your particular
purpose by resorting to an unconventional method (i.e. circumvent the
mechanism intended for this purpose, rather than a by-the-book
approach). By solving the problem this way, sooner or later you'll end
up breaking something. Maintainance may prove difficult later
For me, by-the-book is using "alternatives" utility for this purpose -
intended by the makers way to handle this kind of issues. (switching
between different mail servers, etc.)
Better idea is to adjust symlink to point to the desired binary, rather
than editing PATH variable, deleting the symlink,...
Eclipse has got nothing to do with all this...
