Who are the developers of the J2EE platform?
J2EE is the standard platform for developing multitier enterprise applications based on the Java programming language. The technologies that make up J2EE were developed collaboratively by Sun Microsystems and other software vendors, including BEA Systems. J2EE applications are based on standardized, modular components.
How are J2EE technologies used in WebLogic Server?
Web designers, application developers, and application assemblers create applications and their components by using J2EE technologies such as JavaServer Pages, servlets, Enterprise JavaBeans, and resource adapters. Components are packaged in Java ARchive (JAR) files—archives created with the Java jarutility.
