The only way another process may inherit an environment variable is a child process. In the above case, you could have exported JAVA_HOME before you ran jedit. export PATH="$PATH:/opt/j2sdk_nb/j2sdk1.4.2/jre/bin export JAVA_HOME=/opt/j2sdk_nb/j2sdk1.4.2/jre/lib /usr/bin/jedit Assuming this is the correct location for JAVA_HOME. Probably the best way to do this is in your .bashrc and/or your .xsession or best in /etc/profile On my system it is done when /etc/profile sources /etc/profile.d/alljava.sh. This way you will get all the appropriate JAVA environment variables. One of the most confusing issues I find in my Linux class is trying to explain the difference between environment variables in Unix/Linux and Windows. In Windows, all envornment variables are global and one process can side effect another. In Unix/Linux, this cannot occur. -- Jerry Feldman <gaf at blu.org> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9 -------------- next part -------------- A non-text attachment was scrubbed...
