reinstall java from osx dvd | how2 to perform an optional install
(A) firstly, it is possible to innocently lose ones java (VM framework) - i just discovered my java was totally MIA (not just broken symlinks) from my old tiger partition when i was forced to NOT boot from my leopard partition (because of some weird "no root user" err msg).
so, yes, it is possible!
(B) secondly, these other guys are dead wrong about how to get java back ...
an archive/reninstall of all of osx is totally unnecessary!
Unfortunately, I think you're going to have to do an Archive and Install of Mac OS X, and reinstall all your applications (use the Preserve Users and Network Settings option when doing the archive and install) to get things working properly again.
yes, the osx dvd is all you need ...
no, pacifist not required at all ...
yes, the procedure on the mac for adding java is just as simple as win/linux!
1) navigate to this location on the dvd:
SYSTEMƒ => INSTALLATIONƒ => PACKAGESƒ
2) select (and launch) the correct installer displayed from that list:
"JAVA.PKG"
TaDa!
ps: strangely, the osx software updater does not "see" the fresh (re)install of java & thus does not offer to perform an update automatically :-(
and the updates from the url mentioned by other posters here (at the apple support download site) only covers U5, U6, U7, U8 ... but these all require that the previous updates (U1-U4) have already been applied!
so that is a bit annoying! ... not to mention inconvenient if you want to run a (remotely) modern version of java such as 1.5 (aka Java2).
the solution to this /apparent/ anomaly?:
you must install java 1.5 separately from the base of ver 1.4! - and then proceed to separately download each of the java updates for tiger (one of these seems to actually be a combos update - that include upgrades for ver 1.3 and ver1.4 but nothing for ver 1.5).
you must kick-start the procedure by first installing the first edition/update of java2 aka ver 1.5.
fyi: here are the urls that are returned from a search at apple support with the keywords
Java for Mac OS X 10.4, Release 'x' (where x = 1-8).
=> these are not listed at the software downloads site (requires the search):
