java and classpath

mac1234mac · 03-16-2006, 09:12 AM

Hi!

I'd like to know where I could find paths stored in CLASSPATH.
They must be stored somwhere because when I try to compile program
placed in JDK's folder it works, and when trying to compile the same
program from my home folder it shows errors. Conclusion is that
there is some file in which such paths are stored but where?.

Cheers

From command line

windows

set PATH=c:\PATH\TO\YOUR\JDK\BIN
set CLASSPATH=.

make sure when you set CLASSPATH you are in the folder with the .java file otherwise you will get the same error.

The above method will make you do this everytime so it might help to add the path to your jdk bin folder to your computers path.

In linux:

if using bash just add the directory at the end of your path.

I'm using Linux. What is "end of path"?. How is this done?.
But I'd like to look into file where all paths are stored.

Well for each distro it could be diff.

Im using FedoraCore/Suse/OpenBSD

to see all variables

type: set |less

which will show you all set variables.

Now as setting your path you want to add onto your path. Best way to do this is

cd /home/you

ls -la

vim (vi, whatever you use) .bash_profile

you will see

PATH=$PATH:$HOME/bin

then just add the following

PATH=PATH:$HOME/bin:"YOUR PATH TO JDK/BIN"

hope it helps

I'm using Aurox 11.0, based on Fedora Core 3.
But I have following question:
In which file is stored path to /bin folder?.

Usually java paths are stored in /etc/profile.d/java.sh. An example from a fdc4 working setup would look like this of course your paths would conform to your setup.

Code:

CATALINA_HOME=/usr/local/apache-tomcat-5.5.12/
export CATALINA_HOME

JAVA_HOME=/opt/jdk1.5.0_06/
export JAVA_HOME

TOMCAT_HOME=/usr/local/apache-tomcat-5.5.12
export TOMCAT_HOME

ANT_HOME=/usr/local/apache-ant-1.6.5
export ANT_HOME

export PATH=${PATH}:${JAVA_HOME}/bin:${ANT_HOME}/bin:${TOMCAT_HOME}/BIN:${CATALINA_HOME}/BIN
