Method Detail

getConnectors

public static Connector[] getConnectors()

Returns a list of all the known Connector objects. This includes any of Connector classes which are known about by default, if the requisite classes are present, as well as any whose classes are named in the CONNECTORS_PROPERTY system property.

Returns:

array of avilable connectors

getConnectorActions

public static ConnectorAction[] getConnectorActions()

Returns a list of all the currently available ConnectorAction objects. There will be one for each of the Connectors returned by getConnectors(). Since a ConnectorAction holds open a single connection at a time, this is a sensible method to use if you want to get a list of the current connections to various places. If you want to be able to open guaranteed new connections, use getConnectors itself instead.

Returns:

array of connector actions

showConnectionDialog

public static Connection showConnectionDialog(java.awt.Component parent,
                                              Connector connector)

Pops up a modal dialogue which invites the user to log into a connection using a given connector. The return value will be either a new connection, or null if the user declines to supply correct values. The user will be informed of any errors that occur and invited to retry.

Parameters:

parent - component for the dialogue

connector - connector

Returns:

new connection, or null
