Not on my system (32-bit). If I try to use the Sun jre alone, I get the same errors that Mark reported if I try to set it as the system VM; using it as user VM seemed OK as I recall. Eventually I got tired of having the system vm and the user vm being different (probably me being anal rather than a real "issue"), and since using Sun 1.5.0.* as the user VM hadn't seemed to cause any major issues, I attempted to make it the system VM as well, at which point I got this stuff (this is Mark's, but this was the same error I got): * Found no JDK, setting sun-jre-bin-1.5.0.06 as default system VM javac not found at /opt/sun-jre-bin-1.5.0.06/bin/javac or /opt/sun-jre-bin-1.5.0.06/jre/bin/javac javadoc not found at /opt/sun-jre-bin-1.5.0.06/bin/javadoc or /opt/sun-jre-bin-1.5.0.06/jre/bin/javadoc jar not found at /opt/sun-jre-bin-1.5.0.06/bin/jar or /opt/sun-jre-bin-1.5.0.06/jre/bin/jar rmic not found at /opt/sun-jre-bin-1.5.0.06/bin/rmic or /opt/sun-jre-bin-1.5.0.06/jre/bin/rmic THIS SYSTEM VM IS NOT SUFFICIENT, REQUIRED BINARIES WERE NOT FOUND System Virtual Machine set You may want to update your enviroment by running: "/usr/sbin/env-update && source /etc/profile" Unfortunately I don't remember what was actually in the /bin folder as I have since uninstalled the jre and set both the user and system vm to the sun jdk. But either java and jar really weren't there, or they were and java-config couldn't find them, and in either case I really didn't have the time or interest to investigate the root issue (gotta choose your battles with Gentoo, sometimes ;-) ), so I just switched everything to the jdk (which works fine, despite being only 1.4.2, when some apps I use recommend 1.5.0+), uninstalled the jre (I had previously unmerged/masked the blackdown jre when I installed Sun's) and went on with my week (last week, I think this was). Haven't noticed any issues with having done so; web browsers seem to work, as well as what java-based apps I use. So I admit I don't know what the problem is, and I also concede that it probably shouldn't be happening (as you say), but I confirm that Mark's original issue does seem to be real and that is the workaround/hack I used to bypass it when I encountered it. However, any "real" Java users/developers might find it is inappropriate and I make no guarantees that it is. It's just what worked for me, because I didn't like that error at all-- though I don't necessarily think that it was fatal or even critical or that I would have had "problems" had I just let it stand and used the Sun jre as the system vm (after all, what do I do as root with Java? Nothing, afaik). Holly -- gentoo-user@gentoo.org mailing list
