rpm -e does not support wildcards.

You can use rpm -qa|grep apache|xargs rpm -e to delete, and if there is a dependency, you can add --nodeps.

Uninstall JDK from Linux.

1.Uninstall the JDK version that comes with the system.

#rpm -qa|grep gcj

To uninstall the default installation of JDK:

#rpm -e --nodeps

2.Uninstall the installed JDK

#rpm -qa|grep jdk

Do a self-installing jdk uninstall:

#rpm -e --nodeps

If not, it means that it is not installed.

What version of Linux, if it supports rpm packages, use rpm -qa |grep jdk look it up, the name of the package. Then delete it with rpm -e. If you are using SUSE or OpenSUSE, use yast, go to the software management, search for JDK, and then remove the previous checkmark.

I always install the new JDK and then export it in the environment variables.

find name jdk* The source code package can be deleted directly.
