[SOLVED] Unable to remove java 8 from home(path)

sysmicuser · 08-13-2016, 03:00 AM

No idea how to remove java 8

Code:

[jim@docker1 ~]$ java -version
openjdk version "1.8.0_101"
OpenJDK Runtime Environment (build 1.8.0_101-b13)
OpenJDK 64-Bit Server VM (build 25.101-b13, mixed mode)
[jim@docker1 ~]$

Although I did

Code:

[jim@docker1 ~]$ sudo yum remove java

I dig little further and this is what I see:

Code:

[jim@docker1 ~]$ java -version
openjdk version "1.8.0_101"
OpenJDK Runtime Environment (build 1.8.0_101-b13)
OpenJDK 64-Bit Server VM (build 25.101-b13, mixed mode)
[jim@docker1 ~]$ which java
/usr/bin/java
[jim@docker1 ~]$ ls -l /usr/bin/java 
lrwxrwxrwx. 1 root root 22 Aug 13 14:45 /usr/bin/java -> /etc/alternatives/java
[jim@docker1 ~]$ ls -l /etc/alternatives/java
lrwxrwxrwx. 1 root root 73 Aug 13 14:45 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.101-3.b13.el7_2.x86_64/jre/bin/java
[jim@docker1 ~]$

Please assist me as even I install Java 7 this version overrides thereby I am not able to install Tomcat 8

Find out which package is providing java 1.8

Code:

$ rpm -qf --queryformat='%{name}\n' /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.101-3.b13.el7_2.x86_64/jre/bin/java

then remove that package.

The java package is probably meta package or not actually a package at all and yum is installing whatever package is marked as providing java.

You should provide details of the distribution and version you are using as this will help people to help you.

Thanks for your reply. I actually uninstalled all java packages by quering rpm -qa and then removing each individual package.
