So you're saying the /usr/java/j2sdk-1_4_2_12/bin/java command exists, but it gives you an error when you run it? What is the error?

Hi ... Java needs exactly one thing to run - a path.

There may be other complications (permissions etc) causing a problem.

Look in /usr/java/j2sdk-1_4_2_12/bin and make sure that:
a. java is there, and
b. users have permission to execute it.

Then try (from the command line) echo $PATH - maker sure /usr/java/j2sdk-1_4_2_12/bin is in the path.

Let us know ...

For setting the path variable the syntax is:

PATH= $PATH:/usr/java/j2sdk-1_4_2_12/bin
export PATH

Place this in .profile or .bashrc file in your home directory so that you don't need to do this everytime you login.

Whenever you install java, you need to put it in your path. For Redhat based distros, derivatives and forks (like Mandriva), you can put java in everyones path by simpling placing a bash script in /etc/profile.d, naming it something like java.sh and making it executable. An example of the script I use for Mandriva 2006 and Suse 10.1 is below,

#!/bin/sh
export JAVA_HOME=/opt/java
export MANPATH=$MANPATH:/opt/java/man
export PATH=$PATH:/opt/java/bin:/opt/java/jre/bin

In the script above, java is install in /opt/java, so when modifying the script, make sure the paths match those on your system.

# rpm -ivh j2sdk-1_4_2_12-linux-i586-rpm
# cd /usr/local
# ln -s /usr/java/j2sdk1.4.2_12 java
# cd /usr/bin
# ln -s /usr/local/java/bin java

Edit or replace the .bash_profile for root user

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

JAVA_HOME=/usr/local/java


resource profile
# . ./.bash_profile

# rpm -ivh j2sdk-1_4_2_12-linux-i586-rpm
# cd /usr/local
# ln -s /usr/java/j2sdk1.4.2_12 java
# cd /usr/bin
# ln -s /usr/local/java/bin java

Edit or replace the .bash_profile for root user

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

JAVA_HOME=/usr/local/java


resource profile
# . ./.bash_profile

your code is confusing.

# ln -s /usr/local/java/bin java
ln -s /usr/java/j2sdk1.4.2_12 java

i never heard "java bin"
the directory name is weird.
but thanks for providing info and helping

this code is so simple, much easier to understand.

How do we place "this" in .profile or .bashrc?
