Java SDK 1.4 Install

KptnKrill · 08-14-2003, 05:32 PM

I installed the Java 2 SDK and the install went fine however the compiler and such are in a directory (usr/java/j2sdk1.4.2) and I'm getting sick of typing ...
$ /usr/java/j2sdk1.4.2/bin/javac Program.java
every single time.
Basically, I wondering if there is a way for me to just be able to type "javac Program.java" as if it were a command. tia

You can make a soft link (see ln command) in /usr/bin pointing to your javac and java executables.

Or

You can add the path to the java1.4.2 bin directory in the .bash_profile file.
You will need to append it to the PATH variable.
.bash_profile is located in your user's HOME directory.

Or

If you want to make it global to all users, you will need to edit /etc/profile
You will also need to append the path to the PATH variable.

How would I append my path variable?

Each user (including root) has a file called .bash_profile in there HOME directory.
Edit this file and change the line PATH=$PATH:$HOME/bin to

Code:

PATH=$PATH:$HOME/bin:/usr/java/j2sdk1.4.2/bin

Hmm. It's still not working. I get the horrific "command not found" message. Here's my .bash_profile file. Does anything seem amiss?

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:/usr/java/j2sdk1.4.2/bin
export PATH
unset USERNAME

You need to fully logout for the changes to take effect.
I forgot to mention that part...
