[ngrkic@ui hello.SE]$ cat hello.jdl 
Executable = "run.sh";
Arguments = "";
StdOutput = "std.out";
StdError = "std.err";
InputSandbox = {"run.sh"};
OutputSandbox = {"std.out", "std.err"};
Requirements =  RegExp("ce64.ipb.ac.rs*",other.GlueCEUniqueID);
[ngrkic@ui hello.SE]$ cat run.sh 
#Downloading source code from SE
lcg-cp lfn:/grid/aegis/nikola/hello.SE/hello.c 'pwd'

#Downloading script that compiles source code and execute program
lcg-cp lfn:/grid/aegis/nikola/hello.SE/hello.sh 'pwd'

#runing compile & execute script
./hello.sh

#Uploads output to SE
lcg-cr -l lfn:/grid/aegis/nikola/hello.SE/std.out file:`pwd`/std.out
