Hello I am at a work computer (firewall) I need to add to the CLASSPATH and the PATH to use apache tomcat. Though I know this addition won't disrupt anything I do not have a administrative password. Is there a way to add to these enviornmental system variables? DOS maybe?

in unix

export CLASSPATH=newclasspathhere:$CLASSPATH

in windows

set CLASSPATH=newclasspathhere:$CLASSPATH

same deal with PATH varible
