java.lang.Object
  org.postgresql.ds.common.BaseDataSource
      org.postgresql.ds.jdbc23.AbstractJdbc23ConnectionPoolDataSource

All Implemented Interfaces:

java.io.Serializable, javax.naming.Referenceable, javax.sql.CommonDataSource, javax.sql.ConnectionPoolDataSource

public class PGConnectionPoolDataSource
extends org.postgresql.ds.jdbc4.AbstractJdbc4ConnectionPoolDataSource
implements javax.sql.ConnectionPoolDataSource

PostgreSQL implementation of ConnectionPoolDataSource. The app server or middleware vendor should provide a DataSource implementation that takes advantage of this ConnectionPoolDataSource. If not, you can use the PostgreSQL implementation known as PoolingDataSource, but that should only be used if your server or middleware vendor does not provide their own. Why? The server may want to reuse the same Connection across all EJBs requesting a Connection within the same Transaction, or provide other similar advanced features.

In any case, in order to use this ConnectionPoolDataSource, you must set the property databaseName. The settings for serverName, portNumber, user, and password are optional. Note: these properties are declared in the superclass.

This implementation supports JDK 1.3 and higher.
