Recent information posted on the company\u2019s Web site provides insights into BEA\u2019s thinking on SOAs.\u201cSharing of services is central to the SOA approach,\u201d according to BEA CIO Rhonda Hocker, in a question-and-answer session posted at bea.com. \u201cThe ability to rapidly assemble applications or orchestrate processes is based upon the ready availability of some services that can be shared. Sharing of resources by definition requires governance.\u201d\u201cSwitching to SOA will require a significant shift in development style,\u201d with a focus on code reuse, Hocker said. SOA interfaces are based on Web services and XML, she noted.Java also is on BEA\u2019s SOA to-do list, although BEA acknowledges Java as just one way to implement services. \u201cJava is important as the most prevalent programming standard for implementing services\u201d said Hocker. \u201cThe scale and skills of the Java community guarantee that plenty of high quality skills will be available to build SOAs.\u201dAn enterprise service bus, which would provide messaging services in an SOA, is likely to be part of BEA\u2019s plan as well.HP officials will be prominent at eWorld, focusing on SOAs as well as on \u201cbusiness agility. Knowledge network provider The Middleware Company, for its part, says it will, in conjunction with BEA, unveil technologies and resources to assist developers in building SOAs and service-oriented applications.BEA must play in the SOA game because customers are latching onto the concept, seeking to expose applications as services as opposed to utilizing proprietary, synchronous connections, said Shawn Willett, principal analyst at Current Analysis. \u201cAlmost all enterprise customers say this is a direction they want to go,\u201d Willett said.The company\u2019s SOA strategy will accommodate other vendors\u2019 technologies, according to Ronald Schmelzer, senior analyst at ZapThink.\u201cFirst, they are really shifting their strategy from a story that SOAs will be running on the BEA system to the opposite -- BEA systems running on SOAs that might or might not be BEA-based,\u201d Schmelzer said. \u201cAs a result, the company will be seeking to integrate with systems that are non-BEA-based and extending the WebLogic value proposition to non-developers -- definitely a change for the company.\u201dBEA\u2019s recent financial reports indicate the company may need to diversify its revenue sources. While the company reported total revenues of $262.6 million for the quarter ending April 30, an increase of 11% from the same quarter of last year, license revenues were down 2%, to $120.2 million, from the same time period a year ago.
