The Descriptor’s Body

The body of any XML document begins and ends with the tag for the document’s "root element,” which is defined by the DTD. For a deployment descriptor, the root element is named ejb-jar, and looks like this:

<ejb-jar>
... other elements ...
</ejb-jar>

All other elements must be nested within the ejb-jar element. You can place the following kinds of elements within ejb-jar:

The description element can be used to provide a description of this deployment descriptor. This element can be used in many contexts within a deployment descriptor: to describe the descriptor as a whole, to describe particular beans, to describe particular security roles, etc. The Cabin bean deployment descriptor doesn’t use a description element for the deployment descriptor as a whole, but it does provide a description for the Cabin bean itself.

<display-name> (optional)

The display-name element is used by tools (like a deployment wizard) that are working with the deployment descriptor. It provides a convenient visual label for the entire JAR file and individual bean components.

<small-icon> and <large-icon> (optional)

These elements point to files within the JAR file that provide icons that a deployment wizard or some other tool can use to represent the JAR file. Icons must be image files in either the JPEG or GIF format. Small icons must be 16 × 16 pixels; large icons must be 32 × 32 pixels. These icon elements are also used in the entity and session elements ...
