Attempts to establish a physical database connection that can be
used in a distributed transaction.

Throws:
  • SQLException – if a database access error occurs
  • SQLFeatureNotSupportedException – if the JDBC driver does not support
this method
  • SQLTimeoutException – when the driver has determined that the timeout value specified by the setLoginTimeout method has been exceeded and has at least tried to cancel the current database connection attempt
Returns: an XAConnection object, which represents a physical connection to a data source, that can be used in a distributed transaction
