Strictly speaking, we talk about
managed resources and
administered objects.
Section 20.4 of the spec states:
"Because these resource manager connection factories allow the Container to affect resource management,
the connections acquired through the resource manager connection factory references are called managed resources (e.g., these resource manager connection factories allow the Container to implement connection pooling and automatic enlistment of the connection with a transaction)."
Basically, managed resources are managed by the
J2EE container itself (
JDBC DataSource, etc) while administered objects are managed by a separate server like a JMS provider or a JavaMail server.
