[10:52] Action: daja77 hates lawnmovers in the morning
[10:55] <fake> lawnmovers?
[10:55] <fake> lawnmowers?
[10:55] <daja77> erh yes
[10:55] <daja77> <- sleepy
[10:56] <fake> there was a fire down the street this morning
[10:57] <daja77> isreal bombing vienna now?
[10:57] <fake> it smells like burnt plastic everywhere
[10:57] <daja77> d'oh
[10:57] <fake> no, just a small fire, nothing too spectacular
[10:57] <daja77> but burned plastic smells awful
[11:00] <fake> jep.
[11:24] sai (n=sai@tmpnat1.honeywell.com) joined #rocklinux.
[11:24] <sai> hi
[11:26] <fake> hi sai ;)
[11:26] <sai> I running a java program using shell script. My java program reads input from STDIN. But when i try to run the shell script from cron, the java program stops. 
[11:27] <sai> any idea
[11:28] <fake> make sure JAVA_HOME is set in the shell script
[11:28] <fake> the environment set exported by cron is limited, and doesn't include all of /etc/profile
[11:28] <sai> yes, I export all the classpath and env variable before running that script.
[11:29] <fake> what's the output you get?
[11:29] <sai> No output because its running as background process
[11:30] <fake> cron mails the output of scripts 
[11:30] <fake> if you don't want to configure mail on the host, you can also call java like this:
[11:30] <fake> java ... 2>&1 > /tmp/my-temporary-logfile.txt
[11:30] <sai> Yes, The mistery is the java program stops gracefully. 
[11:31] <sai> Yes i tried that also.
[11:31] <fake> there is no error?
[11:31] <sai> yes
[11:31] <fake> well, then i guess you application is to be examined ;)
[11:31] <sai> even in /var/log/cron i checked
[11:31] <fake> *your
[11:32] <sai> thats right. But is it that, when a program runs in background and expects input from STDIN, will get terminated automatically
[11:34] <fake> that may be true.
[11:34] <sai> Ok.
[11:34] <fake> you can do something like:
[11:34] <fake> java blabla 2>&1 > my_logfile < my_inputfile
[11:35] <sai> ok let me try
[11:35] <fake> where my_inputfile is the input the program expects...
[11:35] <sai> actually program is expecting only a ENTER
[11:35] <fake> then just do:
[11:35] <sai> no characters
[11:36] <fake> java blabla < echo ""
[11:36] <fake> or, to be explicit, you could do:
[11:36] <fake> java blabla < echo -en "\n"
[11:36] <fake> though echo "" does the same.
[11:36] <fake> or 
[11:36] <fake> echo "" | java blabla
[11:36] <sai> Ok, the program logic is something life connect(), then wait for enter, then disconnect
[11:37] <sai> like*
[11:37] <fake> do you have the source?
[11:37] <sai> If that enter goes it will stop.
[11:37] <sai> I am sorry i can show it. 
[11:37] <sai> cannot*
[11:38] <fake> that's not the problem, if you have the source, just patch out the readline
[11:38] <fake> or getch or whatever
[11:38] <sai> ok, and what will be there in place of that
[11:38] <fake> like.... nothing?
[11:38] <fake> why wait for a keypress?
[11:39] <fake> you could detect wether STDIN is connected, i guess
[11:39] <fake> something like
[11:39] <sai> Ok, thats because when we press ENTER the program will stop. Till than it wait for recieving messages from the MQ server
[11:39] <fake> if (!System.in.isClosed()) System.in.getch();
[11:39] <fake> aaaah
[11:39] <fake> ok
[11:39] <fake> now i get it
[11:40] <fake> and you can modify the source?
[11:40] <sai> yah i can 
[11:40] <fake> why don't you remove that whole enter-to-exit thing and make it Ctrl+C instead?
[11:40] <fake> then you'd just need to do...while(1=1)
[11:41] <daja77> not while(true)?
[11:41] <sai> yup that a good idea. But how a program will identify that Ctrl+C is pressed
[11:41] <fake> you need a regulated shutdown?
[11:42] <sai> yes, otherwise it will throw a exception in the MQ server logs
[11:43] <fake> the Destructor of the object containing static void main should be called
[11:43] ija (n=ija@84.19.223.199) joined #rocklinux.
[11:43] <fake> it should... at least.
[11:43] <fake> another options is to open a shutdown port
[11:43] <fake> *option
[11:43] <fake> like tomcat does
[11:44] <fake> you start a java thread listening on a port bound only to 127.0.0.1, if you telnet to it and send a magic word, the program will initiate shutdown 
[11:45] <sai> ok
[11:45] <fake> just a thought.
[11:46] <sai> in case of destructor
[11:47] <fake> let me try that quickly, i'm not sure
[11:47] <sai> are you saying have all the close statements in the desctructor and when i do ctrl+c
[11:47] <sai> destructor will be called
[11:48] <sai> and a graceful close of all the MQ streams will be done
[11:49] <fake> wait a second.
[11:49] <sai> ya
[11:53] <fake> Java has no destructor or similar concept
[11:53] <fake> damn
[11:53] Action: fake did too much C++ lately.
[11:55] <sai> can't we use finally...i am not sure
[11:55] <sai> finally block i mean
[11:56] <fake> i'll try
[11:56] <sai> ok
[11:57] <fake> otoh, there is System.in.available() 
[11:57] <fake> btw
[11:57] <fake> you can check wether STDIN is avalible with that
[11:57] <sai> ok
[11:58] <fake> no, finally does not work, because Ctrl+C doesn't throw an exception
[11:59] <fake> i don't see why you want to run a server with cron, anyways...
[11:59] <sai> hmmmm
[11:59] <fake> the shutdown port option seems to be the cleanest solution
[12:00] <fake> you could do it like this:
[12:00] <sai> yah
[12:00] <fake> when System.in.availible() is true, you could do the Exit-on-Enter thing
[12:00] <fake> and if it isn't, start a java thread listening on a port as described above
[12:00] <fake> that way, you can start and stop the server via cron.
[12:01] <fake> and now i'd really like to know why you ask java questions in #rocklinux ;)
[12:02] <daja77> :)
[12:02] <sai> Because I am running java program in linux Crond
[12:03] <fake> rock linux crond ?
[12:03] <fake> ;)
[12:04] <sai> no fedora core 
[12:04] <fake> ... see? ;-)
[12:04] <sai> ;-)
[12:05] <sai> Thanks a lot  I will try that
[12:05] <fake> good luck!
[12:05] <sai> have a nice day
[12:06] <owl> moin
[12:06] <fake> if you need a sample implementation, i did one once...
[12:06] <sai> can you paste on the terminal
[12:06] <fake> but it was one of my first java programs, so it probably sucks
[12:06] <sai> no problems
[12:07] <fake> sai: see this: https://forums.winamp.com/showthread.php?s=71e9fe1b33d4728200ea2e249fd61e86&threadid=177935&goto=nextnewest
[12:08] <fake> first google hit for "java shutdown port thread howto"
[12:08] <sai> sure
[12:08] <daja77> hm guess my first java programm was sth with beans, a webservice that did the euclid algorithm remote :D

[15:13] <fake> exactly the same in both installations

[15:18] <fake> also the same. grrr...
[15:22] <fake> it's a missing link
[15:22] <fake> well, not a link, but a search path
[15:22] <fake> in RC, it's not looking in /usr/X11R6/lib/X11/xkb/rules anymore, just /etc/X11/xkb/rules

[15:38] <fake> that's why it worked before.
[15:38] <fake> the first entry in the search path is returned, that has a 'xkb' subdirectory.
[15:38] <fake> up until 3.5.2, /etc/X11 wouldn't have worked, because the trailing '/' was missing in the search path list

[20:56] <fake> ok

[21:07] <stf^rocklinux> re
[21:07] <owl> thx. 
[21:08] <stf^rocklinux> sry, I'm currently busy with fighting an ant plague in this 100-year old house, and other non-ROCK related things...
[21:12] <fake> yes, ant is java-related ;)
[21:12] <stf^rocklinux> fake: if it only were that simple :D
[21:14] <stf^rocklinux> fake: so do you have a fix ready for the keyboard thing? maybe move the xkb/rules dir to /etc/X11?
[21:23] <stf^rocklinux> fake: I have already planned to rewrite the legacy package patch... but that could take some time. maybe it's better to skip it for now.
[21:29] <fake> stf^rocklinux: already in sm
[21:30] <fake> stf^rocklinux: the patch to get the keyboard list working. problem description is here:
[21:30] <fake> https://websvn.kde.org/branches/KDE/3.5/kdebase/kxkb/x11helper.cpp?rev=523699&r1=516051&r2=523699
[21:30] <fake> read the backlog...
[21:30] <fake> i'm doing the legacy stuff
[21:31] <stf^rocklinux> hm, I read the links, but didn't see any fix other than reverting the one change shown there...
[21:32] <fake> the fix in submaster just removes the /etc/X11/xkb directory, it's unneded, and breaks the layout selection in this case
[21:34] <stf^rocklinux> anyway, thx for fixing this :)
[21:35] <stf^rocklinux> I'm afk again...
