<DL>
<DT>public interface <B>ManagedConnection</B></DL>
<P>
ManagedConnection instance represents a physical connection
to the underlying EIS.
<p>A ManagedConnection instance provides access to a pair of
interfaces: <code>javax.transaction.xa.XAResource</code> and
<code>javax.resource.spi.LocalTransaction</code>.
<p><code> XAResource</code> interface is used by the transaction
manager to associate and dissociate a transaction with the underlying
EIS resource manager instance and to perform two-phase commit
protocol. The ManagedConnection interface is not directly used
by the transaction manager. More details on the XAResource
interface are described in the JTA specification.
<p>The LocalTransaction interface is used by the application server
to manage local transactions.
