Class DBCPDriverDataSource

java.lang.Object
  org.apache.openjpa.jdbc.schema.SimpleDriverDataSource
      org.apache.openjpa.jdbc.schema.DBCPDriverDataSource

All Implemented Interfaces:

Wrapper, CommonDataSource, DataSource, DriverDataSource, Configurable, Closeable

Direct Known Subclasses:

AutoDriverDataSource

public abstract class DBCPDriverDataSource
extends SimpleDriverDataSource
implements Configurable, Closeable

Commons DBCP basic pooling driver data source. The commons-dbcp packages must be on the class path for this plugin to work, as it WILL NOT fall back to non-DBCP mode if they are missing. For automatic usage of Commons DBCP when available, use AutoDriverDataSource instead.
