we are new to Ubuntu
.Recently we changed my server OS to ubuntu 12.04
from windows 7 . every one have their own login details. one of my college installed Open-Jdk7
. I asked him, where you installed JAVA
, then he suggested to switch the following directory
su root
cd /usr/lib/Jvm
Totally 3 folders are there in JVM folder. names are.
java-1.7.0-openjdk-amd64
java-7-openjdk-amd64
java-7-openjdk-common
generally, If you install Java
in Windows
, we will get 2 folder. 1 folder is for JDK
and another points to JRE
.
but, in Ubuntu we have 3 folders. is it right?
for my conformation, whether he installed correctly or not. I open Terminal
. I run the following 2 commands
javac
java -version
both commands are working fine.
now I want to set-up Java-Home and Path
for all users at same place.because everyone is working on Application server
.
Can anyone explain step-by-step.
Thanks.
/etc/environment
file. It has pretty simple syntax. And to setup user-specific environment variable you should edit~/.bashrc
file. Add theexport VAR=value
to the end of this file.PATH=PredefinePaths:/usr/lib/jvm/java-7-openjdk-amd64/bin
JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64"
. I didn't mention any special charachers in between Path and JAVA-HOME variables. Is it right, What I did
