Apple WebObjects for Mac

From Apple Inc.:

WebObjects 5 provides a comprehensive suite of tools and object-oriented frameworks that allow you to quickly develop and deploy scalable, reusable web and Java applications. By leveraging state-of-the-art, integrated frameworks and tools, it delivers the most mature platform for creating modern browser and client/server applications. No wonder its the environment of choice for leading corporations that need to create compelling Internet sites on time and on budget.

WebObjects is the original object-oriented application server. Unlike other application servers, it handles all the database access and session management for you, cleanly separating your business logic from the user interface and data model. This three-tiered approach makes it easy to develop flexible, maintainable applications while guaranteeing data integrity. It also greatly reduces the amount of application-specific code you need to write. In fact, the presentation and persistence layers of WebObjects are specified using configuration files, so you dont even need to maintain tool-generated Java or SQL code.

Because WebObjects 5 uses a pure Java runtime, its application can easily interact with other Java applications. In addition, WebObjects makes it easy for developers to write as much of their application as they wish using standard J2EE APIs, then integrate that code into a complete WebObjects application.
