I followed this documentation to install java-1.8.0-openjdk-1.8.0.272.b10-1.portable.jdk.el.x86_64.tar.xz into RHEL 7.3.

In section 2.4. Installing OpenJDK on RHEL using an archive, at the last step, 7.Verify that javac -version works without supplying the full path:

$ javac -version
-bash: javac:command not found

I have appended the .bashrc file in the respective user account as follows:

export JAVA_HOME=~/jres/java-8
export PATH="$JAVA_HOME/bin:$PATH"

The full path for JAVA_HOME was: /home/myaccount/jres/java_8

I also edited the .bash_profile inside the /root folder with the

export JAVA_HOME=/home/myaccount/jres/java-8

This helped root account user receive a valid response when typing echo $JAVA_HOME. But it did not solve the java command not found issue.

Will appreciate any inputs to help.

  • When setting JAVA_HOME, did you give the path unquoted? Does it work if you replace ~ (tilde) by $HOME? Did you log in again after the change to your .bashrc? The file is only sourced for new shell sessions. Commented Jan 13, 2021 at 7:38
  • Yes, unquoted. It still does not work. I did login again. The error persisted. Commented Jan 13, 2021 at 8:30
  • Have you actually looked where the javac executable got installed? Try find ~/jres -name javac. Commented Jan 13, 2021 at 8:41
  • No. Thanks for asking. When I typed this command, there was no output or errors. The location ~/jres/java-8 was created using symlink of the JDK location at /usr/java/jres/java-1.8.0-openjdk-1.8.0.272.b10-1.portable.jdk.el.x86_64, after I searched this JDK location, I found it in the bin folder.
