public class EmbeddedConnectionPoolDataSource

extends EmbeddedDataSource

implements javax.sql.ConnectionPoolDataSource

EmbeddedConnectionPoolDataSource is Derby's ConnectionPoolDataSource implementation for the JDBC3.0 environment.

A ConnectionPoolDataSource is a factory for PooledConnection objects. An object that implements this interface will typically be registered with a JNDI service.

EmbeddedConnectionPoolDataSource automatically supports the correct JDBC specification version for the Java Virtual Machine's environment.

• JDBC 3.0 - Java 2 - JDK 1.4, J2SE 5.0

EmbeddedConnectionPoolDataSource is serializable and referenceable.

See EmbeddedDataSource for DataSource properties.
