Java SE (Java Platform, Standard Edition)

In installed j2sdk1.4.0 in usr/java. I then installed JEdit in
usr/share/

From the path usr/share/jedit/4.0 I entered 'java -jar jedit.jar'

I get an error java: command not found.

I can not get any .jar files to run because I get the same error.

Any suggestions to get this or any .jar file working?

I tried setting the path in my .bash_profile which is included below.
(do I need to shut down and restart to make this effective?)

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then . ~/.bashrc fi

# User specific environment and startup programs
PATH=$PATH:usr/java/j2sdk1.4.0/bin
export PATH unset USERNAME
export CLASSPATH=/usr/java/j2sdk1.4.0/bin:/usr/java/j2sdk1.4.0/jre/bin:
export CLASSPATH=$CLASSPATH:/usr/share/jedit/4.0/jedit.jar
JAVA_HOME=/usr/java/j2sdk1.4.0
export JAVA_HOME



fyi
