public class EmbeddedConnectionPoolDataSource
extends EmbeddedDataSource
implements org.apache.derby.iapi.jdbc.EmbeddedConnectionPoolDataSourceInterface

This datasource is suitable for an application using embedded Derby, running on full Java SE 6 and higher, corresponding to 4.0 and higher. EmbeddedConnectionPoolDataSource is a ConnectionPoolDataSource implementation.

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 4.0 - Java SE 6
• JDBC 4.1 - Java SE 7
• JDBC 4.2 - full Java SE 8

Use BasicEmbeddedConnectionPoolDataSource40 if your application runs on Java 8 Compact Profile 2.

EmbeddedConnectionPoolDataSource is serializable and referenceable.

See EmbeddedDataSource for DataSource properties.
