Constructor Detail

XAConnectionFactory

protected XAConnectionFactory(String resourceName,
                              String userName,
                              String passwd,
                              XADataSource xaDataSource,
                              JdbcTransactionalResource res)

Constructor for subclasses with their own transactional resource.

XAConnectionFactory

public XAConnectionFactory(String resourceName,
                           String userName,
                           String passwd,
                           XADataSource xaDataSource)

Creates a new instance with a given resource name, user name and password for the XADataSource.

Parameters:

resourceName - The unique resource name for the corresponding JdbcTransactionalResource (which will be created automatically).

userName - The user name to use for getting XA connections. Null if no authentication is supported by the supplied XADataSource.

passwd - The password for the user, or null if no authentication is supported by the supplied XADataSource.

xaDataSource - The XADataSource to use.

XAConnectionFactory

public XAConnectionFactory(String resourceName,
                           String userName,
                           String passwd,
                           XADataSource xaDataSource,
                           XidFactory xidFactory)

Creates a new instance with a given resource name, user name and password for the XADataSource, and a custom XidFactory.

Parameters:

resourceName - The unique resource name for the corresponding JdbcTransactionalResource (which will be created automatically).

userName - The user name to use for getting XA connections. Null if no authentication is supported by the supplied XADataSource.

passwd - The password for the user, or null if no authentication is supported by the supplied XADataSource.

xaDataSource - The XADataSource to use.

xidFactory - The custom XidFactory.

Method Detail

getUserName

protected String getUserName()

Used by getPooledConnection() to get a connection. If the drivers do not support authentication, then an empty string should be returned here.

Returns:

String The user name, or null if not applicable.

getPassword

protected String getPassword()

Used by getPooledConnection() to get a connection.

Returns:

String The password, or null if not applicable.

getXADataSource

public XADataSource getXADataSource()

This method gets the underlying data source. It is called by getPooledConnection() to get connections.

Returns:

XADataSource The data source to get XAConnections from.

setExclusive

public void setExclusive(boolean exclusive)

Sets the connections generated to exclusive for 2PC. This mode is needed for certain databases that do not conform to XA entirely.

Parameters:

exclusive - If true, then connections will be kept until after commit/rollback, resulting in lower reuse.

isExclusive

public boolean isExclusive()

Tests if the connections that are generated will be exclusive or not.

Returns:

boolean True iff connections are exclusive.

getTransactionalResource

public TransactionalResource getTransactionalResource()

Get the transactional resource.

Returns:

TransactionalResource The transactional resource.

getPooledConnection

public XPooledConnection getPooledConnection()
                                      throws IllegalStateException,
