-bash: java: command not found

[pfassett]

I did a search but couldn't find this topic so I hope it's not a repeat.

I am pretty new to linux so bear with me.

So I downloaded and installed the JRE (java runtime enviro) and now I am trying to run the commands for java.

myservername:/# java -version
-bash: java: command not found

I am trying to use java to install a .jar for commons fvs. But none of the java commands are working. I tried restarting but that didn't do anything. Do I have to enable the commands after installing.

Hi

I think you have installed debian , and debian contains jav in the repositories.

But if you want the newest version here is the solution.

you must add java to the path

find out where you installed java and add it to the path

export PATH=$PATH:"/path/to/java/jre/bin"

the bold part is fix.

for example here is my case

i have java installed jdk in /usr/java/jdk1.5.0_05/

set the path

export PATH=$PATH:"/usr/java/jdk1.5.0_05/bin"


if you want make this to run every start of a terminal put the export line into your .bashrc file

Sorry, like I said I am new to this. I didn't quite understand your post.

I entered in the export PATH=$PATH:"/path/to/java/jre/bin" like you said, but nothing seems to happen. I still get the command not found.

My Java install is located here as far as I know. I am logged in as root.

/usr/local/java#

in your .bashrc file put this

PATH=$PATH:/opt/java/bin
export PATH
JAVA_HOME=/opt/java
export JAVA_HOME

and use real values on your machine. either log out and back in or source that file and try again.

I think you can also make a symlink /etc/alternatives/java and point it to your java file (/usr/local/java/bin/java, or whatever)

Hi

now you know where your java installation is located.

the code

export PATH=$PATH:"/usr/local/java/bin"

or

exprt PATH=$PATH:"/usr/local/java/jre/bin"

i am not exactly sure but i think the first command will work
