If you are a Java programmer, then you are likely no stranger to the tedious and time-consuming process of writing SQL code for persisting Java objects in a relational database. This article introduces you to the support included in SAP Web Application Server (SAP Web AS) 6.40 for entity beans with container-managed persistence (CMP entity beans) — the Java technology that provides transparent persistence for your J2EE application data. You will learn the fundamentals of CMP entity beans, and how to develop and use them. By the end of this article, you will be able to develop your first CMP entity beans with SAP NetWeaver Developer Studio and run them in SAP Web AS 6.40.
