Features J2EE 1.3 Compatibility, Improved Team Development and a

Unified Development Environment for SilverStream eXtend

SilverStream Software, Inc. (Nasdaq: SSSW) today announced the immediate availability of its powerful J2EE 1.3 compatible development and deployment environment, SilverStream eXtend(TM) Workbench 2.0. A key component of the SilverStream eXtend product suite, SilverStream eXtend Workbench (eXtend Workbench) provides Java developers with a highly productive environment for quickly developing and deploying sophisticated Web, wireless and portal applications.

SilverStream eXtend Workbench 2.0 is now fully J2EE 1.3 compatible and provides several new features to improve team development. eXtend Workbench is a useful tool that simplifies and accelerates the development and deployment of J2EE and Web services applications. Where it really provides value is as the integrated development environment for SilverStream eXtend Director (eXtend Director). A powerful and flexible J2EE application framework, eXtend Director provides full-featured engines for content management, workflow, rules, security, and more - all the infrastructure required to deliver powerful Web services containing relevant information and transactions to enhance interactions with key constituents.

As a J2EE application, eXtend Director offers the flexibility to use any J2EE IDE, but tight integration with eXtend Workbench provides significant advantage for developers. New Features in eXtend Workbench 2.0 include:

-- The Power of J2EE 1.3: Quickly and easily incorporate new and improved J2EE 1.3 technologies such as Enterprise JavaBeans (EJB) 2.0, Java Connector Architecture (JCA) and Java Transaction Service (JTS), among others, to build standards-based applications that are portable across platforms.

-- Ease of Migration: Migrate from J2EE 1.2 to J2EE 1.3 with a conversion wizard that automatically updates deployment descriptors and other required definitions. Backwards compatibility ensures the continuity of applications developed with previous versions of J2EE.

-- Improved Team Development: Integration with any source control systems including pre-packed integrations for CVS, RCS, PVCS, VSS and ClearCase facilitates team development and reduces development time, enabling IT teams to rapidly deliver new Web, wireless and portal applications that significantly impact operations.

-- High-performance Web services: eXtend Workbench has been extensively tested and optimized for interoperability with all leading SOAP 1.1 implementations. It includes an advanced Web services wizard, a powerful WSDL editor and a fully integrated UDDI Registry Manager that empowers organizations to build Web services today.

-- Unmatched Productivity: Improved editing and code completion capabilities along with powerful wizards and editors reduce the complexity of J2EE and Web services projects. Intuitive visual designers make it easier to develop multifaceted J2EE applications that include workflow, business rules, content management and other services provided by eXtend Director.

-- Ease of Deployment: Provides one-button deployment to all leading J2EE application servers including J2EE 1.3 by generating the necessary deployment descriptors and deployment plans.

eXtend Workbench also features a number of intuitive designers and wizards for creating portal components, rule conditions and actions, workflow activities to build and design eXtend Director applications. All these visual tools are seamlessly integrated with eXtend Workbench to provide a single, unified view of development projects. This reduces the complexity of developing and deploying J2EE and Web services applications.

"While J2EE 1.3 provides enhanced usability compared to previous releases, J2EE application development remains complex and deployment can be a tedious process that varies greatly across application servers," said Frank Auger, vice president of product marketing and management for SilverStream Software. "We developed SilverStream eXtend Workbench to provide customers with an open, flexible development environment that provides one-button deployment to all leading J2EE application servers. With the latest release of eXtend Workbench, SilverStream has raised the bar for enterprise-class platforms by providing a highly productive and easy-to-use environment that reduces the complexity of developing applications with J2EE and Web services."

Applications built with the SilverStream eXtend product suite are fully standards-based and portable, deploying to market-leading J2EE application servers including IBM WebSphere, BEA WebLogic and the SilverStream eXtend Application Server, making SilverStream eXtend the first comprehensive product suite to deliver on the promise of J2EE.
