PostgreSQL™ includes one implementation
of ConnectionPoolDataSource named
org.postgresql.ds.PGConnectionPoolDataSource.
JDBC requires that a
ConnectionPoolDataSource be configured via
JavaBean properties, shown in Table 11.1, “ConnectionPoolDataSource Configuration Properties”,
so there are get and set methods for each of these properties.
Table 11.1. ConnectionPoolDataSource Configuration Properties
| Property | Type | Description |
|---|---|---|
serverName | String | PostgreSQL™ database server host name |
databaseName | String | PostgreSQL™ database name |
portNumber | int | TCP port which the PostgreSQL™ database server is listening on (or 0 to use the default port) |
user | String | User used to make database connections |
password | String | Password used to make database connections |
defaultAutoCommit | boolean |
Whether connections should have autocommit enabled or disabled
when they are supplied to the caller. The default is
false, to disable autocommit.

Many application servers use a properties-style syntax to configure these properties, so it would not be unusual to enter properties as a block of text. If the application server provides a single area to enter all the properties, they might be listed like this:
serverName=localhost databaseName=test user=testuser password=testpasswordOr, if semicolons are used as separators instead of newlines, it could look like this:
serverName=localhost;databaseName=test;user=testuser;password=testpassword
