Rational Application Developer Overview


Published on

IBM Rational Integrated development environments such as IBM® Rational® Software Architect and IBM® Rational® Application Developer for WebSphere Software improve code quality by making it easier to catch defects earlier in the development cycle. Because it takes longer to analyze and design changes to software than it takes to implement the changes, an IDE must provide automated tools to help visualize the impact the changes will have. Such an IDE minimizes the likelihood of negative impacts from changes and simplifies the impact analysis process.

  • SIP (Session Initiation Protocol) is a peer-to-peer protocol used to establish, modify, and terminate multimedia internet protocol (IP) sessions between two endpoints including telephony and instant messaging.A SIP application is a Java™ program that uses at least one SIP servlet where a SIP servlet is a Java-based application component that is managed by a SIP servlet container (for example, WebSphere® Application Server).Here are some common uses of SIP in telecommunications-based applications: Voice-over-IP (VoIP) Instant messaging Click to call Call notification, forwarding, blocking SIP servlet specifications were developed under the Java Community Process: JSR-289 SIP Servlet 1.1 APIJSR-116 SIP Servlet 1.0 APIBoth the SIP 1.1 and SIP 1.0 specifications are based on the Java servlet application programming interface (API). SIP Servlet v1.1 (JSR 289) is a revision of the initial SIP Servlet v1.0 (JSR 116) Specification with additional enhancements. It defines the API for the SIP servlet programming model, clarifies the roles and responsibilities of the SIP servlet container, and describes the convergence of SIP with Java EE components.Converged SIP applicationsA converged SIP application is an application that uses both HTTP Servlet API and Java EE components. A converged SIP application can be either of the following combinations:SIP and HTTP converged applications, hosting SIP and HTTP servlets SIP and Java EE converged applications, hosting SIP, HTTP, and Java EE components such as web services Converged SIP applications created in the workbench are packaged as a WAR file in an EAR file.Differences between SIP 1.0 and SIP 1.1There are some key differences between Session Initiation Protocol (SIP) 1.0 and SIP 1.1 in areas such as the deployment descriptor, annotations, and servlet specifications.

  • DANAService Mapping provides a way of insulating an application that consumes a service from the details of that service provider's interface or location. This is achieved by providing a simple way of performing content-based routing and message transformation. This helps in many scenarios – for example,Service versions: When a service is modified to cope with additional requirements, its interface and location are likely to go through modifications that, although small, are likely to break existing service consumers'Meet in the middle': When a business unit defines the service interface that it expects to use to perform some task, this may well not match the details of an existing 'enterprise service' owned and offered by the IT organisation...and many more
