Course outline from www.IntertechTraining.com Users can click the E-mail button, type their e-mail addresses into a text box on a pop-up dialog, and get the same course outline delivered to their inboxes, shown in Figure 3-21. This is amazingly easy to do. The same User Control generates the outline whether the output is going to the Web or getting packed into the body of a mail message. Here s the code that captures the Page rendering and sends it off via SMTP .

Pooled connection (or physical connection): A pooled connection instance represents a single connection to a database that remains open during use by a series of logical connection instances. Logical connection: A logical connection is a connection instance (such as a standard Connection instance or an OracleConnection instance) returned by a pooled connection instance. It is the pooled connection checked out by an application at a given point in time. When we use connection pooling, we essentially introduce an intermediate step to enable reuse of a physical connection. The connection pool data source returns a pooled connection, which encapsulates the physical database connection. We then use the pooled connection to return JDBC connection instances (one at a time) that each act as a temporary handle (the logical connection). When an application closes the logical connection, it does not result in the closing of the physical database connection. It does, however, clear the connection state, restore the defaults (e.g., it resets autocommit to true if you had set it to false), and mark the underlying physical connection (or pooled connection) as available for creating the next logical instance from the connection pool. To actually close the physical connection, you must invoke the close() method of the pooled connection. This action is typically performed in the middle tier that manages the connection pool, and not by the application. re ocim In this case, the object reference is marshalled as a pointer to the C code, and you don t need the && operator in order to call the function; the object is pinned to ensure that it does not move during the function call.. Figure 14-3 shows the JDBC interfaces related to connection pooling and their Oracle counterparts. Note that as an application developer, you will typically not deal with the PooledConnection and ConnectionPoolDataSource interfaces described in this section. These interfaces are implemented for you by the connection cache (either the sample Oracle9i connection cache or the implicit connection cache in 10g). So feel free to skip the section Oracle9i Connection Caching if you are not interested in this topic.
