EAServer is an application server, which includes an integrated set of development tools that you use to deploy Web applications that support high-volume traffic, dynamic content, and intensive online transaction processing. The EAServer product set includes Adaptive Server Anywhere.
EAServer provides a framework for deploying the middle-tier logic of distributed component-based applications.
EAServer simplifies the creation and administration of Internet applications that service thousands of clients simultaneously. EAServer components execute on the middle-tier between end-user client applications and remote databases. EAServer 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.
EAServer scalability and platform independence allow you to develop your application on inexpensive single-processor machines, then deploy the application on an enterprise-grade multiprocessor server.
EAServer provides:
A modular, lightweight, high-performance J2EE container based on a dynamic Java-components framework for executing standard J2EE components
Dispatch and stub/proxy support for all major component models, including JavaBeans, PowerBuilder, Java, and C/C++
Dynamic HTML support using Java servlet and JavaServer Pages
Java 2 Enterprise Edition (J2EE) platform support
Graphical administration with the Management Console, including component interface browsing, declarative role-based security, password, and required SSL session characteristics, server and user certificate management, and transaction and runtime monitoring
Tight integration with the PowerBuilder development environment
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
Asynchronous processing support
Web server redirector plug-in forwards client requests directly to a Web server
EAServer provides plug-ins for Eclipse and Borland JBuilder version 10. The EAServer plug-ins conform to Section 508 guidelines, and are internationalized and localizable.
