Constructor Detail AbstractPoolConnectionManager public AbstractPoolConnectionManager(String backendUrl, String backendName, String login, String password, String driverPath, String driverClassName, int poolSize)(Code) Creates a new AbstractPoolConnectionManager instance. Parameters:   backendUrl - URL of the DatabaseBackend owning thisconnection manager. Parameters:   backendName - name of the DatabaseBackend owning thisconnection manager. Parameters:   login - backend connection login to be used by this connectionmanager. Parameters:   password - backend connection password to be used by this connectionmanager. Parameters:   driverPath - path for driver Parameters:   driverClassName - class name for driver Parameters:   poolSize - size of the connection pool.
