One way that you can set your JAVA_HOME variable and add to your PATH, is be doing the folowing.

As 'sudo' open up /etc/bash.bashrc and add the following to the end of the file.

NOTE: Set the java path to whatever the actual path is on your environment if it does not match /usr/lib/jvm/java

    JAVA_HOME=/usr/lib/jvm/java
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH

When you reboot, try running the following:

    $ echo $JAVA_HOME
/usr/lib/jvm/java
 echo $PATH
[probably lots of paths]:/usr/lib/jvm/java/bin

Introduction

Java is a technology from Oracle (formerly: Sun Microsystems). There are several implementations, of which five will be discussed here:

OpenJDK: The primary goal of the OpenJDK project is to produce an open-source implementation of the Java SE Platform (6 and 7). This is the default version of Java that Ubuntu uses and is the easiest to install.
Oracle (Sun) Java 6: Oracle (Sun) Java 6 is the reference implementation for Java 6.
Oracle Java 7: Oracle Java 7 is the reference implementation for Java 7.
IBM Java: IBM Java is the preferred Java solution on PowerPC machines. It is a reimplementation with a Just-In-Time Compiler. It is only available from IBM's website.
GNU Compiler: A Java compiler made by GNU. Only developers should have to install this.

This plugin works with the main browsers: Firefox, Chromium, Google Chrome, and Epiphany.

On Konqueror, go to Settings → Configure Konqueror... and from menu select Java & JavaScript, then tick Enable Java globally option.
