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.

Icwri is a lightweight, very simple, service-oriented Java built-in script. It can help Java developers build some application interfaces in a service-oriented style. It can also help non-technical people join the development team to write their own application scripts to enforce business rules and decisions. Icwri service providers and consumers can be either Icwri scripts or Java classes. An Icwri script can run all alone, but the primary purpose of Icwri script is to have an assistant language of Java. It can run on any system with JDK/JRE 1.5 or above installed. It does not support Java SE 6 Script Engine because of the service-oriented design and the requirement to support Java SE 1.5 users.
