InfoCenter Home > 4: Developing applicationsFor IBM WebSphere Application Server, applications are combinations of building blocks that work together to perform a business logic function. Synonymous with enterprise applications, applications can contain enterprise beans, but do not have to. At most: enterprise applications = enterprise beans + Web applications Web applications are groups of one or more servlets, plus static content. Web applications = servlets + JSP files + XML files + HTML files + graphics The J2EE (JavaTM2 Platform Enterprise Edition) model introduces a number of new programming concepts including: Thin clients are remote clients that pass data for processing to an enterprise bean running on the application server. See article Java clients for more information. The J2EE model packages enterprise and Web applications into the new categories of EAR files and WAR files.
The Application Assembly Tool (AAT) creates the WAR, EAR, and JAR files, and assembles application components into Web modules. View the supported specification levels for servlet, JSP, and EJB APIs at the WebSphere Application Server prerequisites Web site. See article 4.1 to review the WebSphere application programming model and environment, including information on various tools to help you develop and test your application components.
