# Accessing the Network Server by using a DataSource

The Derby Network Client driver DataSources `org.apache.derby.jdbc.ClientDataSource` and `org.apache.derby.jdbc.ClientConnectionPoolDataSource` are supported by the Network Server. If your client runs on JDK 1.6 or higher, the DataSources are, instead: `org.apache.derby.jdbc.ClientDataSource40` and `org.apache.derby.jdbc.ClientConnectionPoolDataSource40`
