Chapter 6 Creating J2EE Applications for BEA WebLogic
BEA WebLogic Server implements the J2EE platform specification, which includes Servlets, Java Server Pages (JSPs), Enterprise JavaBeans (EJBs), Java Messaging Service (JMS), and other platform services.
J2EE services provide access to standard network protocols, databases, and messaging systems. When developing applications, developers can create, assemble, and deploy components that use these services.
Web components provide the presentation logic for browser-based and wireless applications, while EJB components encapsulate business objects and processes. Components run on J2EE application services, such as Java Database Connection (JDBC), JMS, and Java Transaction API (JTA), and are executed in either the WebLogic Web container or EJB container. Containers provide lifecycle support and services defined by the J2EE specifications so that developers do not have to be concerned with many of the details of transactions, security, database connectivity, and other underlying system infrastructure.
