No, sorry, that's not relevant for compiler errors.
here is the log : [...]
the full log is attached. thx
Unfortunately the logs don't show any useful errors. Could you please look on the domjudge-live image under /var/lib/domjudge/judgings/domjudge-live-0/endpoint-default There should be subdirectories of the form cX-sYY-jZZ for each submission/judging there. Check in the webinterface what one of the java compiler-errror's submission and judging ID is and please send a zip file of that directory. The files compile.{out,tmp,meta} may contain some clues as to what goes wrong. Jaap

Hi Adi Ansyah,
First, which version of DOMjudge are you using? Is this on the live image?
If not, did you build a chroot environment with the script dj_make_chroot and enable it in etc/judgehost-config.php? See the documentation: https://www.domjudge.org/docs/admin-manual-8.html#ss8.1
Finally, to trace down the problem, please send us the judgedaemon log file, which should be located under $PREFIX/domjudge/judgehost/log/judge.$HOSTNAME.log

Ok, so what I see here in compile.meta: the compile script ran for 1 second, but actually didn't use any CPU time, then it received an alarm signal (probably because of running out of time) and then the terminate signal. In the admin interface under configuration settings, what are the "script timelimit" and "script memory limit" set to? Secondly, in compile.{tmp,out} there is the line: cp: 'Main.java' and './Main.java' are the same file Are you using the "java_javac" compile script (instead of the default "java_javac_detect")? Because this is the only place I see where a 'cp' command is executed in the compile phase, see: https://github.com/DOMjudge/domjudge/blob/master/sql/files/defaultdata/java_... If so, this could explain things in combination with the fact that the submitted file is already named "Main.java". Could you try submitting a Java source with a filename different from the main class? Also, please try and switch to the "java_javac_detect" compile script. Please send any error messages and the associated judging zip files. Jaap

owh its working. it's so depressing that the problem was that simple. i did set the script timelimit to 1 before but forgot to change it back. i found another problem. when i upload with file name Main.java, its working fine. but when i upload with different file name, its compiler-error. i did upload from a different user and different team but the result is compiler-error. i checked here https://www.domjudge.org/docs/admin-manual-8.html#ss8.4 it says that the file name must be Main.java and class name must be Main. is that normal?? or is there a way to upload with different file name other than Main.java?

great that it's working now!
i found another problem. when i upload with file name Main.java, its working fine. but when i upload with different file name, its compiler-error. i did upload from a different user and different team but the result is compiler-error. i checked here https://www.domjudge.org/docs/admin-manual-8.html#ss8.4 it says that the file name must be Main.java and class name must be Main.
is that normal?? or is there a way to upload with different file name other than Main.java?
I assume you use the java_javac compile script. If you change that to java_javac_detect it will detect the class with a public main method and use that one. Tobi
im sorry, im really new in domjudge and linux. can you explain how to change it to java_javac_detect ? On Thu, Nov 12, 2015 at 8:33 PM, Tobias Werth <werth@cs.fau.de> wrote:
