Take a peek under the hood of <A HREF="http://www-128.ibm.com/developerworks/workplace/library/wcs-architecture/index.html?ca=drs-">IBM Workplace Collaboration Services</A> and learn about the layers that make up Workplace Collaboration Services, including IBM WebSphere Application Server and IBM WebSphere Portal. Long-time users of IBM Lotus Notes and Domino (especially those using them for more than just email) know full well the richness of functionality and the power of the platform for creating all kinds of collaborative applications. Many Notes/Domino fans are not, however, sure what benefits they can derive from combining the power of their Domino-based applications with IBM's J2EE (Java 2, Enterprise Edition) frameworks and product offerings.
