Question

I installed js-comint mode on Emacs 24. Now when i try to execute run-js, it throws the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/mozilla/javascript/tools/shell/Main
Caused by: java.lang.ClassNotFoundException: org.mozilla.javascript.tools.shell.Main

Could not find the main class: org.mozilla.javascript.tools.shell.Main. Program will exit.

Process js exited abnormally with code 1

The variable inferior-js-program-command is "/usr/bin/java org.mozilla.javascript.tools.shell.Main", and for some reason it doesn’t work. What should i do to be able to run inferior javascript process in Emacs? If the above error means that i don’t have some Java library, what package should install in Debian?

I use Linux Mint Debian Edition (corresponds to Debian testing). I have openjdk-6-jre installed.

Ok, i’ve found a workaround. I installed rhino package on my Debian and put "/usr/bin/rhino" in variable inferior-js-program-command, now Emacs successfully runs inferior javascript process. However i’m still interested, why didn’t /usr/bin/java org.mozilla.javascript.tools.shell.Main didn’t work on my system.
