WebSphere Rapid Deployment:

WebSphere Rapid Deployment is designed to simplify the development and deployment of WebSphere applications. It is a collection of Eclipse plug -ins that can be integrated within development tools or run in a headles s mode, without headers, from a user file system.
WebSphere Rapid Deployment is currently integrated in Rational Web Developer, Rational Application Developer, and the Application Server Toolkit. Initially, there are features that are only supported in headless mode.
During development, annotation -based programming is used. The developer adds metadata tags into the application source code that are used to generate artifacts needed by the code, thus reducing the number of artifacts the developer needs to cre ate.
These applications are packaged into an enhanced EAR file that contains the J2EE EAR file along with deployment information, application resources, and properties (environment variables, JAAS authentication entries, shared libraries, classloader settings, and JDBC resources). During installation, this information is used to create the necessary resources. Moving an application from one server to another also moves the resources.
WebSphere Rapid Deployment automates installation of applications and modules onto a running application server by monitoring the workspace for changes and then driving the deployment process.
