The Sony Ericsson Java Platform is a set of profiles describing particular Sony Ericsson Java implementation.
 It was designed to help developers to focus on a platform rather than on a variety of different product names.
 Two platform branches exist, supporting Symbian (SJP) and non-Symbian (JP) based phones respectively.

 For example, the Java Bluetooth APIs (JSR 82) are only enabled for phones which actually support Bluetooth wireless technology.
 These interfaces are mostly invisible to the end user, who only has to download a JAR file containing the application to the phone.
