Dear Sir,

First: I use chroot /chroot directory to enter chroot environment, then I test java -version and javac -version => it's work.

Outside chroot: I compile java with javac hello.java --> java hello => Output: Hello World.
Inside chroot: I do as same as.

Now I will try to compile java outside chroot, and run it inside chroot! I will reply you later!

Thanks for your support

Best regard,
Linh

To check your java installation in the chroot:

Did you try (without the use of DOMjudge)
- to compile a simple java program outside of the chroot
- and to execute the resulting class file in the chroot

Best,
Tobi
