public ConnectionFactoryNotPooledImpl()
Method Detail

checkOutJdbcConnection

public java.sql.Connection checkOutJdbcConnection(JdbcConnectionDescriptor jcd)
                                           throws LookupException
Description copied from class: ConnectionFactoryAbstractImpl
Returns a valid JDBC Connection. Implement this method in concrete subclasses. Concrete implementations using Connection pooling are responsible for any validation and pool removal management.

Note: This method is never called for a jdbc-connection-descriptor that uses datasources, OJB only manages connections from DriverManager.

Note: If the concrete implementation does not callback to ConnectionFactoryAbstractImpl.newConnectionFromDriverManager(org.apache.ojb.broker.metadata.JdbcConnectionDescriptor) when creating a new Connection, it must call ConnectionFactoryAbstractImpl.initializeJdbcConnection(java.sql.Connection, org.apache.ojb.broker.metadata.JdbcConnectionDescriptor) so that the platform implementation can peform any RDBMS-specific init tasks for newly created Connection objetcs.

Specified by:
checkOutJdbcConnection in class ConnectionFactoryAbstractImpl
Parameters:
jcd - the connection descriptor for which to return a validated Connection
Returns:
a valid Connection, never null. Specific implementations must guarantee that the connection is not null and that it is valid.
Throws:
LookupException - if a valid Connection could not be obtained

releaseJdbcConnection

public void releaseJdbcConnection(JdbcConnectionDescriptor jcd,
                                  java.sql.Connection con)
                           throws LookupException
Description copied from class: ConnectionFactoryAbstractImpl
Releases a Connection after use. Implement this method in concrete subclasses. Concrete implementations using Connection pooling are responsible for any validation and pool removal management.

Note: This method is never called for a jdbc-connection-descriptor that uses datasources, OJB only manages connections from DriverManager.

Specified by:
releaseJdbcConnection in class ConnectionFactoryAbstractImpl
Parameters:
jcd - the connection descriptor for which the connection was created
con - the connection to release. Callers must guarantee that the passed connection was obtained by calling ConnectionFactoryAbstractImpl.checkOutJdbcConnection(org.apache.ojb.broker.metadata.JdbcConnectionDescriptor).
Throws:
LookupException - if errors occured during release of object. Typically happens if return of object to pool fails in a pooled implementation.
