This topic helps you find best practices for developing your Java 2 Platform,
Enterprise Edition (J2EE)-compliant applications.
Developing WebSphere applications
This topic provides development, assembly, and deployment instructions that are specific to various types of applications. For example, you can focus on developing Web applications or Web services; or extending your applications with the application programming interfaces of the messaging or security subsystems.
This topic describes how to assemble enterprise application modules (EAR
files) from new or existing Java 2 Platform, Enterprise Edition (J2EE) Version 1.3 or 1.4 modules, including these archives: Web application archives (WAR),
resource adapter archives (RAR), enterprise bean Java archive (JAR) files,
and application client archives. This packaging and configuration of code artifacts into application modules or stand-alone Web modules is necessary for deploying the applications onto the application server.
This topic describes how to configure class loaders. It includes both configuration performed during application assembly (packaging) and configuration performed at the server. The product run-time environment uses class loaders to find and load new classes for an application. Class loaders are part of the Java virtual machine (JVM) code and are responsible for finding and loading class files.
This topic describes how to deploy applications onto application servers,
and then how to administer the deployed applications. It includes installing applications, starting applications, exporting application files, updating applications, removing applications, and other common tasks
