JDBC Connection Pool Manager : Closing the Connection Pool
 

Closing the Connection Pool

To ensure that the connection pool is closed correctly when an application stops running, the application must notify the DataDirect Connection Pool Manager when it stops. If your application runs on JRE 1.3 or higher, notification occurs automatically, so the application does not have to send notification. For JRE 1.2, the application must explicitly notify the pool manager of termination using a special close method defined by DataDirect as shown in the following example:
if (ds instanceof com.ddtek.pool.PooledConnectionDataSource){
com.ddtek.pool.PooledConnectionDataSource pcds = (com.ddtek.pool.PooledConnectionDataSource) ds;
pcds.close();
}
