Eclipse can be seen as a very advanced Java program. Running Eclipse may sound simple—simply run the included
eclipse executable—yet in practice, you may want to tweak the inner workings of the platform. First, Eclipse does not come with a Java virtual machine (JVM), so you have to get one yourself. Note that Eclipse 3.0 needs a 1.4-compatible Java runtime environment (JRE).
