WebLogic: The Definitive Guide

Deployment Considerations

In this section, we consider some of the implications of deploying applications to a single-server development environment, as well as the changes to your deployment strategy when migrating to a multiserver domain or clustered domain. We examine how you can partially redeploy files within web applications and EJB modules, and also examine class visibility restrictions on resource adapters. In addition, we cover how to effectively package shared utility classes within an enterprise application. Finally, we look at how to register server-specific startup and shutdown classes, and how to register application-specific listener classes that respond to specific events during the deployment life cycle of the application.

Single-Server Deployment

Suppose your domain consists of a single WebLogic server — a setup that is typical during the development stages of your application. This means that you’re deploying applications directly to the Administration Server itself for development purposes. This setup is ideal for iterative development environments, where your IDE in combination with build scripts can deploy to WebLogic Server as you develop your applications.

Setting up this scenario is quite simple — you need to create a WebLogic domain that consists of the Administration Server alone. As we saw earlier, this single-server setup automatically defaults to the development mode. This means you can immediately begin deploying your application components by placing ...
