Chapter 1 Introducing Jaguar CTS

About Jaguar CTS

Jaguar CTS (Component Transaction Server) provides a framework for deploying the middle-tier logic of distributed component-based applications.

Jaguar CTS simplifies the creation and administration of Internet applications that service thousands of clients simultaneously. Jaguar components execute on the middle-tier between end-user client applications and remote databases. Jaguar provides efficient management of client sessions, security, threads, third-tier database connections, and transaction flow, without requiring specialized knowledge on the part of the component developer.

Jaguar's scalability and platform independence allow you to develop your application on inexpensive single processor machines and then deploy the application on an enterprise-grade multiprocessor server.

Feature summary

Jaguar CTS provides the following features:

• A scalable, multithreaded, platform-independent execution engine
• Dispatch and stub/proxy support for all major component models, including JavaBeans, PowerBuilder, Java, ActiveX, and C/C++
• Dynamic HTML support using Java servlet, Java Server Pages, and PowerDynamo Web sites
• Java 2 Enterprise Edition (J2EE) platform support
• Graphical administration with Sybase Central™, including component interface browsing, declarative role-based security, password, and required SSL session characteristics, server and user certificate management, IDL module support, OTS transaction monitoring, and runtime monitoring
• Tight integration with the PowerBuilder and PowerJ development environments
• Transparent client-session and component-lifecycle management
• Connection caching to allow reuse of remote database connections
• Industry-standard naming services to resolve components using logical names rather than server addresses
• Transaction management to simplify the design and implementation of an application's transactions
• Transparent thread-safety features to simplify use of shared data and resources
• Result-set support to enable efficient retrieval of tabular data in client applications
• Declarative, role-based security to restrict client connections and the components that can be invoked by a specific client session
• Identity-based security to restrict intercomponent calls.
• Asynchronous messaging support

The following sections explain these features in detail.
