J2ME just the Java Platform

I believe J2ME doesn't represent an alternative to Jini, but
rather something upon which Jini could run in embedded and
consumer devices. The main difference to J2ME from what Sun
was trying to do before with Embedded and Personal Java, was
the idea of profile APIs. Rather than trying to figure out a
set of APIs that make sense for all small and medium sized
Java platform implementations, Sun decided to let industry
segments -- such as car, set top box, cell phone, etc.. --
figure out what APIs made sense for them. Each API set is
called a profile, which sits on top of a JVM and bare bones
set of APIs. The JVM and bare bones APIs are called J2ME.

J2ME just means Sun's Java Platform for small embedded or
consumer environments, on top of which Jini could run.
