The Java ME Platform SDK can be installed on a system running a supported operating system version. All users with an account on the host machine can access the SDK. This feature is called the Multiple User Environment.
Note - The Multiple User Environment supports access from several accounts. It does not support multiple users accessing the SDK simultaneously. See Switching Users.
To support multiple users the SDK creates an installation directory that is used as a source for copying. This document uses the variable work to represent the SDK working directory and installdir to represent the installation directory. Each user’s personal files are maintained in a separate working directory named javame-sdk that has a subdirectory for each version installed.
