Homework and Emergencies Homework & Coursework Questions Java doesn´t find the CLASSPATH (System variable) Post 302982179 by rovf on Monday 26th of September 2016 05:34:59 AM

You didn't set the environment variable CLASSPATH, but a shell variable of this name, i.e. only the shell sees this. What you did here is similar to setting a variable in your Java program, then run a shell program from Java and hope that the Java variable is visible to the shell program.

In shell context, "environment variables" are sometimes also called "exported variables", because the child processes can see them. Each shell has a different way to set an environment variable. For example, bash or zsh use the command export, while csh or tcsh use the command setenv.

You didn't specify, which shell you are using. Consult the man page of your shell to find out, how to set environment variables.
