I'm pretty new to Apache Tomcat and somewhat new to Linux altogether. I am trying to install the JDK, which is a prereq for Apache Tomcat. I downloaded and untarred the JDK to /usr/java and now I'm trying to set the environment path. I opened root's .bash_profile and added the following lines:

export JAVA_HOME

export PATH

But after I log out and back into the root profile and type


to test the changes all it returns is a blank line. Echoing $PATH doesn't return a path with the jdk directory included either.

I'm not sure what I did wrong, can anyone help?

  • Beyond the obvious problem, this is not where you should be setting this variable in Tomcat. /path/to/tomcat/bin/setenv.sh is the recommended place for container variables. For a more detailed overview of this topic, you can refer to a related answer of mine here. You can skip the "looking for customizations" step.

You have to add that to your login script I believe, those changes are erased @ logout if I'm not mistaken. I've had the same issue on debian (Ubuntu) machines. Try manually adding the Java path to $Path like

export PATH
