Spring ME is a version of ME that not only runs on your cell phone, but also on any other Java platform not supporting reflection. It is to Java ME what Spring is to Java SE and Java EE, which is indicated by the name. However, the "ME" (Micro Edition) suffix not only refers to the platform it supports. It also refers to the size of the runtime, which is pretty minimal. In fact, it's pretty much non-existent, and therefore ideal for situations in which you cannot afford the sheer size of the traditional Spring runtime.
