public class Settings
extends Object
implements Service

This class defines some settings of the server. The settings are read from the configuration file. This implies that the configuration must be loaded when this class is initialized.

                            String errHeader)

Prints a header line and a stack trace for the given Error or Exception

Parameters:

err - a throwable.

errHeader - the text for the header line

getBaseDir

public static File getBaseDir()

Return the base directory (from the configuration).

Returns:

a File object

getTempDir

public static File getTempDir()

Return the temporary directory (from the configuration).

Returns:

a File object

setBaseDir

public static void setBaseDir(String dir)

Set the base directory.

Parameters:

dir - the directory path

getServerId

public static String getServerId()

Get the id of the server.

Returns:

a string containing the server name

getAvailableLocales

public static Locale[] getAvailableLocales()

Return the list of locales from the configuration.

Returns:

an array of Locale objects

setAvailableLocales

public static void setAvailableLocales(Locale[] l)

Change the list of locales.

Parameters:

l - an array of Locale objects

getDecimalFormatter

public static NumberFormat getDecimalFormatter()

getLocalNumberFormatter

public static NumberFormat getLocalNumberFormatter()

startup

public void startup()

Description copied from interface: Lifecycle

This method is called when the object is "started".

Specified by:

startup in interface Lifecycle

shutdown

public void shutdown()

Description copied from interface: Lifecycle

This method is called on shutdown.

Specified by:

shutdown in interface Lifecycle

isRunning

public boolean isRunning()

Description copied from interface: Service

Ask the object if it has been started

Specified by:

isRunning in interface Service
