IBM Lotus Expeditor Toolkit provides a complete, integrated set of tools that allows you to develop, debug, test, package, and deploy client applications to IBM Lotus Expeditor V6.1, IBM Lotus Sametime V7.5.1, and IBM Lotus Notes V8. You can use the toolkit to develop the following types of client applications:
Eclipse Rich Client Platform (RCP) applications (desktop client only)
Eclipse embedded Rich Client Platform applications
Web applications
Embedded transaction applications
Portlet applications (desktop client only)
Database applications
Messaging applications
Web services applications

The toolkit provides wizards that enable you to create Client Services projects to develop client applications. The toolkit uses target definitions to provide a convenient method for you to specify the runtime environment, the build-time environment, and the set of components that can run on the platform. For example, when you create a Client Services project, you select a target definition from a list of available targets, and then a set of features from a list in the target definition. The toolkit uses this information to automatically set up the Java build path and runtime for your project. You can then edit, compile, and debug your project. The toolkit provides a default list of target definitions; however, you can also create your own definitions.

At a minimum, Lotus Expeditor Toolkit requires Eclipse 3.2.1. For most functions, including the sample used in this article, you should also install the Eclipse Web Tools Platform (WTP). This can be installed from the predefined Callisto Discovery site available in Eclipse. If you do not already have a version of Eclipse and the Eclipse Web Tools Platform installed, you can download and install the Java EE project bundle of Eclipse from the IBM Callisto Simultaneous Release project page. The Java EE project bundle and Lotus Expeditor Toolkit together provide everything needed for development of Java, Web, and Web services applications for Lotus Expeditor. Most application types can be created using just Eclipse Callisto (3.2.2), WTP, and the toolkit. If you create embedded transaction applications or portlet applications, you need to install Rational Application Developer V7.0. If you are not already a Rational Application Developer customer, you can download and install an evaluation version of the software. Prior to installing Lotus Expeditor Toolkit in Rational Application Developer, be sure to update to the latest fix pack of the Rational software.
