Classes that pertain to resource managers
Derby provides two variants of each DataSource interface
defined by the JDBC API.
Applications that run on the J2SE 1.4 or 1.5 platform must use the first
variant. Applications that run on the Java SE 6 platform can use either of the
two variants. However, the DataSource methods specific to the JDBC 4 API
are available only from the second variant (the one whose class name ends with "40").
If an application is running on the Java SE 6 platform, all connection objects
returned from the DataSource will be JDBC 4 connection objects,
regardless of which DataSource variant is in use.
The Derby implementation classes for the DataSource interfaces are as
follows:
- org.apache.derby.jdbc.EmbeddedDataSource
and org.apache.derby.jdbc.EmbeddedDataSource40
Implements the javax.sql.DataSource interface,
which a JNDI server can reference. Typically this is the object that you work
with as a DataSource.
- org.apache.derby.jdbc.EmbeddedConnectionPoolDataSource
and org.apache.derby.jdbc.EmbeddedConnectionPoolDataSource40
Implements the javax.sql.ConnectionPoolDataSource interface.
A factory for PooledConnection objects.
- org.apache.derby.jdbc.EmbeddedXADataSource
and org.apache.derby.jdbc.EmbeddedXADataSource40
Derby's
implementation of the javax.sql.XADataSource interface.
See the javadoc for each class for more information.
