Review the system configuration to ensure old versions of JRE have been removed. There are two ways to uninstall Java. Use the method that you used when you installed Java. For example, if you used RPM to install Java, then use the RPM uninstall method. If RPM is installed, first query to ascertain that JRE was installed using RPM. Search for the JRE package by typing: # rpm -qa | grep -i jre If RPM reports a package similar to jre--fcs, then JRE is installed with RPM. If JRE is not installed using RPM, skip to "Self-extracting file uninstall". To uninstall Java via RPM, type: # rpm -e jre--fcs Self-extracting file uninstall: 1. Browse folders to ascertain where JRE is installed. Common locations are /usr/java/jre_ or opt/jre_nb/jre_/bin/java/ 2. When you have located the directory, you may delete the directory by using the following command: Note: Ensure JRE is not already installed using RPM before removing the directory. # rm -r //jre Ensure only one instance of JRE is installed on the system. # ps -ef | grep -I jre If more than one instance of JRE is running, this is a finding.
