## org.apache.derby.jdbc
Class ClientConnectionPoolDataSource

    java.lang.Object
      org.apache.derby.jdbc.ClientBaseDataSource
          org.apache.derby.jdbc.ClientDataSource
              org.apache.derby.jdbc.ClientConnectionPoolDataSource

All Implemented Interfaces:
  java.io.Serializable, javax.naming.Referenceable, javax.sql.ConnectionPoolDataSource, javax.sql.DataSource

    public class ClientConnectionPoolDataSource

extends ClientDataSource
implements javax.sql.ConnectionPoolDataSource

ClientConnectionPoolDataSource is a factory for PooledConnection objects. An object that implements this interface will typically be registered with a naming service that is based on the Java Naming and Directory Interface (JNDI). Use ClientConnectionPoolDataSource if your application runs under JDBC3.0 or JDBC2.0, that is, on the following Java Virtual Machines:

- JDBC 3.0 - Java 2 - JDK 1.4, J2SE 5.0
- JDBC 2.0 - Java 2 - JDK 1.2,1.3
