Smart businesses with Smalltalk investments can be front-runners in the race to e-business success
For some time, Smalltalk developers may have thought they would be left behind while the business world embraced Java in the race toward e-business profit. After all, IBM's software strategy leverages Java™ and Enterprise JavaBeans™ cross-platform standards in the IBM Framework for e-business. (The Framework is IBM's field tested methodology for developing, deploying and managing e-business applications.) Businesses with investments in Smalltalk began to face the prospects of retraining developers or hiring new skills to make the transition to e-business. These companies would have to spend time and money to update existing Smalltalk applications, when they should have been building new e-business applications.
But businesses with Smalltalk investments can be front-runners in the race to e-business success. The new VisualAge Smalltalk Version 5 supports the IBM Framework for e-business by delivering improved Java interoperability and integration with IBM WebSphere Application Server. WebSphere provides a robust infrastructure for consistent Web application deployment on industry leading platforms, based on Java servlets and Enterprise JavaBeans. It provides the ability to scale the Web environment to meet and exceed user demand.
Last year with Version 4.5, VisualAge Smalltalk began to interoperate with Java. The connection was made through Server Smalltalk (SST), using the Remote Method Invocation (RMI) model for distributed objects. Then IBM worked to make this interoperability simpler for developers. In Version 5, announced in July, VisualAge Smalltalk has a new wizard to help generate the Java-to-Smalltalk mapping definitions for RMI, saving precious time in the development cycle.
VisualAge Smalltalk can strengthen a company's e-business presence while adding life to corporate assets through another new capability, one that integrates existing Smalltalk applications with the IBM WebSphere Application Server. VisualAge Smalltalk Version 5 has a new servlet interface for leveraging the power of the WebSphere environment and making it easier to implement e-business Web applications. The servlet interface works as a transport between the Smalltalk image and the HTTP server. With Version 5, developers won't need to rework current Smalltalk applications to use WebSphere.
More businesses are expanding their markets by extending their reach to customers who are using Web browsers. VisualAge Smalltalk Version 5 provides tools to build server applications that produce data for Web clients. Smalltalk lets you call from JavaServer Pages and servlets to Smalltalk business logic running on the solution server through the Web Connection feature or the SST RMI function. To support the IBM Framework for e-business, Version 5 enables access to Smalltalk business logic from an enterprise bean using the SST RMI framework and tools. Enterprise JavaBeans is the common programming model of the IBM Framework for e-business, which enables developers to focus on writing business logic and not plumbing, separates the development decision from the deployment decision, and supports widespread reuse of software components.
VisualAge Smalltalk remains the tool of choice for companies with Smalltalk skills when building strategic, mission-critical applications that require complex business logic and have frequently changing requirements. Companies that value VisualAge Smalltalk for these reasons include The Chubb Group of Insurance Companies; AlliedSignal, a world leader in the aerospace and automotive industry; and TeleService Resources, the second-largest call center service provider in North America and a subsidiary of AMR Corp./American Airlines.
Making a smooth transition to e-business while leveraging investments in Smalltalk is a great reason to use VisualAge Smalltalk Version 5. Its increased Java interoperability and integration with WebSphere can help companies succeed at e-business--while evolving at their own pace, using their developers' current skills, and without reworking vital business applications. The race to e-business just became less costly and time-consuming for Smalltalk users.
