BEA and Siebel Systems Announce Availability of Siebel Component Assembly for WebLogic 9.0; Solution Accelerates J2EE Development and Deployment of Custom CRM Applications; Advances Companies' Aligned Vision for Delivery of SOA.

BEIJING & SAN MATEO, Calif. -- Siebel Systems, Inc. (NASDAQ:SEBL), a leading provider of customer-facing solutions, and BEA Systems, Inc. (NASDAQ:BEAS), a world leader in enterprise infrastructure software, today announced the general availability of Siebel Component Assembly for J2EE-based BEA WebLogic Server 9.0. The combined offering is designed to help customers to significantly simplify and speed the development of custom CRM applications, enhance organizational decision-making, and increase end user productivity. The solution also represents a major milestone in an ongoing partnership between BEA and Siebel Systems to deliver on a common vision for Service Oriented Architecture (SOA) via their respective Services Infrastructure and Customer Adaptive Solutions software.

BEA's Services Infrastructure vision promotes the free flow of business processes, information, and services to help organizations rapidly compose, configure, and reuse technology assets to more efficiently meet evolving business needs. Siebel Customer Adaptive Solutions deliver compelling CRM applications that allow companies to understand and anticipate a customer's needs; rapidly design and implement customer-centric processes; continually realign those processes for systemic, consistent improvements; and direct the right actions across organizations to help maximize customer satisfaction and profitability. Siebel Component Assembly on WebLogic Server 9.0 represents the convergence of these visions with two industry-leading products that have incorporated standards-based reusable composite application development for enterprise-grade applications.

With Service Oriented Architecture and industry standards as the blueprint, companies like BEA and Siebel can provide organizations with a proven, scalable and secure environment designed to help them to quickly build their individual Customer Adaptive Solutions.

"A Service Oriented Architecture is now a viable strategic direction for companies," said Sheryl Kingstone, Program Manager, Customer-Centric Strategies, Yankee Group. "When Yankee Group interviewed IT executives' use of SOA we found that 30 percent were not only replacing applications and business processes with SOA-based ones, but that 28 percent were augmenting existing applications and core business processes with SOA. When asking these executives which type of project the SOA initiative is addressing or will address, we found that 65 percent are currently evaluating or deploying SOA for customer-facing initiatives. Siebel Component Assembly on WebLogic Server 9 provides a head start for companies that want to build custom applications that are scalable, flexible, and secure."

"Siebel Component Assembly for WebLogic 9.0 is another example of how BEA continues to attract leading enterprise-based application developers to our application server," said Jeff Pendleton, Vice President, Product and Solutions Marketing, BEA Systems. "We are committed to continuing our relationship with Siebel and driving SOA-based development and standards forward."

Continuing Commitment to SOA

BEA and Siebel share a common vision to better empower customers to enjoy the benefits of SOA. In addition to building Siebel Component Assembly, the two companies, along with other industry-leading vendors, collaborated on a broad industry effort to architect an open, language-independent specification for building SOA applications called Service Component Architecture (SCA). Announced on November 30, 2005, SCA is a programming model designed to simplify the development of creating business services and includes an update to the Service Data Objects (SDO) specification for accessing data residing in multiple locations and formats. The work on Siebel Component Assembly provided a critical use case and requirements to this over-arching specification, defining how developers can quickly describe services and data graphs using metadata and wire and re-wire them together to quickly assemble relevant customer-adaptive solutions. SCA and SDO are available royalty free, and the authors are soliciting industry feedback.
