ClientBase client

A ClientBase object forms the core of any Ganymede client. It does the work to get us connected and logged into the server, and serves as a reference point for the server to talk to if something unusual happens.

Method Detail

changePassword

public boolean changePassword(java.lang.String username,
                     java.lang.String oldPassword,
                     java.lang.String newPassword)

This method actually does the work of logging into the server, changing the password, committing the transaction, and disconnecting.

There are three basic steps involved in changing the password. First, the client must log on to the system, getting a handle on the Session object. Next, we get a handle on the password field of the user object, and change the value. Finally, we commit the transaction.

error

public void error(java.lang.String message)

Send output to this.

This just prints out the message, but could be directed to a dialog or something later.

disconnected

public void disconnected(ClientEvent e)

Called when the server forces a disconnect.

Call getMessage() on the ClientEvent to get the reason for the disconnect.

Specified by:

disconnected in interface ClientListener

messageReceived

public void messageReceived(ClientEvent e)

Called when the ClientBase needs to report something to the client. The client is expected to then put up a dialog or do whatever else is appropriate.

Call getMessage() on the ClientEvent to get the message.

Specified by:

messageReceived in interface ClientListener

main

public static void main(java.lang.String[] argv)

If this class is run from the command line, it will act as a text-mode password client.

loadProperties

private static boolean loadProperties(java.lang.String filename)

Load the properties file that we use to identify the Ganymede server and port for the command line client.
