WebServices.Org - The Web Services Community Portal - All under one roof with BEA's WebLogic Enterprise Platform "Achieving business objectives with Web services requires more than just building applications on Web services standards such as SOAP and WSDL. It requires a runtime framework for loosely coupled integration and an architecture that supports asynchronous conversations and business messaging frameworks. It needs to be developed, deployed, integrated and orchestrated, all on a reliable framework. BEA meets these challenges, recognises that its WebLogic Server is a market leader and builds on this product with its WebLogic Enterprise Platform."
