Newbie PATH help
 

I am new to Linux and have been feeling my way around quite well. However when I tried to install Limewire on Fedora Core 2 I had problems as it said that there was no Java VM installed in my PATH? I had already installed the latest version of Java and checked to see that the VM worked in Firefox.

How and what do I need to do to change the PATH? I know it is in /etc/profile but what would I need to enter in the profile so that Limewire sees the java VM?


Any help would be excellent and I hope one day I will be answering questions for the thousands of people that will soon be joing the community when they realise that monopolies are bad.

Welcome to Linux & LQ !!
 

First, you can set the PATH for all users except root in /etc/profile, and also each user even root has their own .bash_profile file located in ~ (~ = home foler) where you set the path for that expecific user. To see your path you simple type: echo $PATH at the command prompt; the path is a variable where you tell "linux" in which directories it must search for binary files, there are other enviroment variables for library and stuff too.
Now, down to business :cool:
Open a terminal, su to root(su -). then: cd /etc/profile.d/ , there you will create a file: "java.sh" : vim java.sh
Using vim: type: "i" To insert, to start typing, then when you´re done press [Esc] + [Z] [Z] or press [Esc] and type :wq
Ok, in your java.sh file you must put something like this:



Note that you should replace /java/j2re1.4.2_05 with your java path, and maybe it will be different if you downloaded the SDK version.

Now, if you want this new path to work in your current login, you simply do: source /etc/profile.d/java.sh

Hope this helps,

Thank you very much for your help sorry it took me so long to get back to you but just installed fedora core 3 and been going through the usual update thing with yum.

Not working!!
 

I have done exactly what you told me and everything worked fine in editing my $PATH, I also had a problem with gxine not seeing gtk2 so I added that as well. I know exactly where my files directory is i.e: /usr/java/j2re........

However when i then tried to install limewire I got the very same message in a terminal, that there was no JVM in my path!!!! any ideas?

Thanks a lot for your time and for helping me.

Bhambullet.

Are you doing this as root ? If so when you changed to root did you do 'su' or 'su -' ?
If you do su you have root powers but not neccessarily root's path. 'su -' makes you root.
I hope that makes sense.

I logged in as root and did everything you told me to. I checked that the directory paths where correct but even though I have done this like you told me to I cannot get limewire or gxine to compile.

Is there anything else I can do?

I am using Fedora Core test 3 with the 2.6.9 kernel

Type the following at a command prompt as root and post the results
:-

whereis libraryname

echo $PATH

Hopefully this will tell if these are correct or not.

I ran into the same problem. It seems that there is a dummy java program installed by Fedora in at "/usr/bin/java". So, when you append the path as "export PATH=$PATH:$J2RE_HOME/bin", the new path does not override the old path since it does not come first. I changed that line to "export PATH=$J2RE_HOME/bin:$PATH", and found that the old path was properly overridden. By the way, you can see the full path of a program that would be called up by using the 'which' command, which program will be called up. For example, when I type 'which java', I get ''/opt/jdk1.5.0/bin/java'. Before I edited the /etc/profile.d/java.sh file, I got '/usr/bin/java'.
Good Luck
