Managing J2EE Risks

摘要

It's been six years since the java 2 plat-form, Enterprise Edition (J2EE) changed the face of multitier application development. Based on Sun Microsystems' open specifications, J2EE comprises more than 10 different technologies, among them Enterprise Java-Beans (EJB), Servlets, Java Server Pages (JSPJ and Java Message Service (JMS). Applications built using J2EE depend on the execution of a fairly complex product-the J2EE application server that's generally supplied by such vendors as IBM (WebSphere), BEA (WebLogic), Sun (Sun ONE Application Server) and Oracle (9iAS). These products include the containers that actually execute the application components along with tools for development, assembly, deployment, administration and monitoring.
