ERROR: JAVA_HOME /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.362.b08-1.el7_9.x86_64/jre/bin/java does not exist.

This error message indicates that the system is unable to locate the Java Development Kit (JDK) installation directory. The JAVA_HOME environment variable should point to the root directory of the JDK installation, not the JRE directory.

To fix this error, you need to set the JAVA_HOME environment variable to the correct directory. To determine the correct directory, you can use the following command:

$ sudo update-alternatives --config java

This command will display a list of installed Java versions and their installation paths. Once you have determined the correct path, update the JAVA_HOME environment variable in your shell profile (e.g., ~/.bashrc or ~/.bash_profile) by adding the following line:

export JAVA_HOME=/path/to/java

Make sure to replace /path/to/java with the actual path to the JDK installation directory. Save the changes and reload your shell profile by running the following command:

$ source ~/.bashrc

After this, the error should be resolved, and you should be able to use Java without any issues.
