Early forms of Lotus Expeditor were first outlined publicly in 2001 in an article on IBM's Pervasive Computing Device Architecture. which were associated with the pursuit of ubiquitous computing. Lotus Expeditor has its roots in IBM's Pervasive Computing (PvC) initiatives. Lotus Software uses Expeditor in many of its own products, including Notes (from version 8), Sametime (from version 7.5), and Symphony. It runs on top of the Eclipse integrated development environment. In addition, Lotus Expeditor Toolkit is for developers to create Expeditor applications and create customized Expeditor runtimes. Client applications can run standalone, and optionally exploit the services of the Lotus Expeditor Server for data synchronization, transactional messaging and automated, remote, application management. Expeditor Server is not necessary for Expeditor Client applications to run. It runs on top of the IBM DB2 database management system and the Java EE-based IBM WebSphere Application Server. Lotus Expeditor Server is used to deploy, configure and maintain applications running on Lotus Expeditor Clients.This configuration of the platform includes the Eclipse embedded Rich Client Platform (eRCP) running on a Java ME virtual machine. Lotus Expeditor Client for Devices is a configuration of platform for Microsoft Windows Mobile devices and the Nokia E90 Communicator.These applications can be written using a combination of OSGi, Java EE, and Eclipse Rich Client Platform (RCP) technologies, running on a Java virtual machine. Lotus Expeditor Client for Desktop is used for the running client applications on Microsoft Windows, Mac OS X and Linux.
