org.apache.openjpa.jdbc.schema
Class DBCPDriverDataSource

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

All Implemented Interfaces:

Wrapper, CommonDataSource, DataSource, DriverDataSource, org.apache.openjpa.lib.conf.Configurable, org.apache.openjpa.lib.util.Closeable

Direct Known Subclasses:

AutoDriverDataSource

public class DBCPDriverDataSource
extends SimpleDriverDataSource
implements org.apache.openjpa.lib.conf.Configurable, org.apache.openjpa.lib.util.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.

public Connection getConnection(Properties props)
                         throws SQLException

Overrides:

getConnection in class SimpleDriverDataSource

Throws:

SQLException

close

public void close()
           throws SQLException

Specified by:

close in interface org.apache.openjpa.lib.util.Closeable

Throws:

SQLException

getDBCPConnection

protected Connection getDBCPConnection(Properties props)
                                throws SQLException

Throws:

SQLException

getDBCPDataSource

protected DataSource getDBCPDataSource(Properties props)

isDBCPDataSource

protected boolean isDBCPDataSource()

This method should not throw an exception, as it is called by AutoDriverDataSource to determine if user already specified to use Commons DBCP.

Returns:

true if ConnectionDriverName contains org.apache.commons.dbcp, otherwise false

isDBCPLoaded

protected static boolean isDBCPLoaded(ClassLoader cl)

This method should not throw an exception, as it is called by AutoDriverDataSource to determine if it should use DBCP or not based on if org.apache.commons.dbcp.BasicDataSource can be loaded.

Returns:

true if Commons DBCP was found on the classpath, otherwise false

startConfiguration

public void startConfiguration()

Specified by:

startConfiguration in interface org.apache.openjpa.lib.conf.Configurable

endConfiguration

public void endConfiguration()
