What sort of laptop is it ? I've noticed some problems with Xorg on my Toshiba M100 laptop where something similar was happening. I logged the following bug: http://bugs.opensolaris.org/view_bug.do?bug_id=6179960 As a workaround, from a terminal, try running "xset -dpms" to see if this helps. > b. on my laptop, there are 2 network interfaces, > rtls0 and ath0. > > rtls0: flags=201000802<BROADCAST,MULTICAST,IPv4,CoS> mtu 1500 index 6 > inet 0.0.0.0 netmask 0 > ether 0:16:d4:15:7f:71 > ath0: flags=201004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4,CoS> > mtu 1500 index 7 > inet 192.168.1.100 netmask ffffff00 broadcast 192.168.1.255 > ether 0:16:cf:b:54:d6 > > i did not change the order in /etc/nwam/lpp, although i > tend to use the wireless interface more often. > > sometimes, my network connection appears to > have gone away. firefox stopped working, and > ping complained that www.yahoo.com is unknown. > > if i ping my dns server using its IP address, ping > reports that the dns server is alive. > > this suggests that the network connection is still > present, but somehow the resolver on the laptop > stopped working ? > > how can i find out what is wrong ?

Looking at a install DVD that I have, the netbeans-5.5-appserver.tar.bz2 contains the SUNWappserver package, and a flat directory "netbeans-5.5" You should be able to pkgrm SUNWappserver, or just rm -rf the directory to free up more space. No idea why the uninstaller isn't working. cheers, tim -- Tim Foster, Sun Microsystems Inc, Solaris Engineering Ops http://blogs.sun.com/timf
