What are environment entries?

Rating:

Environment entries are declared by the bean provider in the deployment descriptor. Their values can be changed by the deployer at the deployment time. The values set by the deployer cannot be changed programmatically, as these are read-only values. These entries are represented in the deployment descriptor using the <env-entry> element. The environment entries are valid for a single bean. Two different beans can have environment entries with the same name. However, two environment entries within a bean cannot have the same name. The <env-entry> element has the following sub-elements:

• <description>
• <env-entry-name>
• <env-entry-type>
• <env-entry-value>

These values can be accessed using the java:comp/:env context. The data type for specifying the environment entries must be a String or a Wrapper.
