public class INIT

extends ZVerb

The INIT class performs a Z39.50 Init request to a Z39.50 server hosting a database. INIT uses input parameters contained in a RequestManager object, or a RequestManager object and a URL String. A successful execution of INIT results in establishment of a Z39.50 session with the server. If execution fails, a FailurePage exception is thrown.

It is important to note that a Z39.50 Init request will be issued on all Z39.50 commands if it has not been performed. This class is provided as a way to specifically request the action.

The valid input widgets for the INIT class are:
dbname or
dbgroup
If the widgets are not specified, then INIT will default to the "dbname"/"dbgroup" values stored in the user state. If available, the user's AccessClient will provide the Z39.50 Authorization and password, otherwise, the default server authorization defined in the configuration files is passed in the initialization request.
