Using container-managed persistence beans with SOA

The article shows you how to use IBM WebSphere Process Server to take control of the connectivity and persistence logic for container-managed persistence (CMP) beans, enabling them to be stored to non-relational datastores. You learn about the various data access patterns that are supported and step through basic usage scenarios that include demonstrated examples ranging from very simple to somewhat complex. This article covers some best practices, such as using Service Component Architecture (SCA) from within the special Java class, UserDefinedPushDownMethodsImpl, enabling reuse of services that expose legacy systems via a service-oriented architecture (SOA), and insulating you from needing to know all of the details involved in communicating with the non-relational datastore.
