The Contents of a Deployment Descriptor (Enterprise JavaBeans)

10.2. The Contents of a Deployment Descriptor

We've discussed XML deployment descriptors throughout this book. At this point, you probably know enough to write deployment descriptors on your own. However, it's still worthwhile to take a tour through a complete deployment descriptor. Here's the deployment descriptor for the Cabin bean, which we created in Chapter 4, "Developing Your First Enterprise Beans". It contains most of the tags that are needed to describe entity beans, and session beans aren't much different. We'll use this deployment descriptor to guide our discussion in the following sections.
