restart

public void restart()
             throws IOException

Description copied from interface: RequestLoggerMBean

Registers a new request logger at the application. You need a request logger for some functions of the session bean. Be aware that sessions will be logged from this time on, so they may not reflect the actual number of sessions. Also, if one was registered, it will be replaced by a new one, which then starts over counting, disregarding the current ones.

Only available for web applications.

Specified by:

restart in interface RequestLoggerMBean

Throws:

IOException

See Also:

• RequestLoggerMBean.restart()

stop

public void stop()
          throws IOException

Description copied from interface: RequestLoggerMBean

Removes any set request logger from the application. You need a request logger for some functions of the session bean.

Only available for web applications.

Specified by:

stop in interface RequestLoggerMBean

Throws:

IOException

See Also:

• RequestLoggerMBean.stop()

getRequestLogger

protected IRequestLogger getRequestLogger()

Gets the request logger for this application.

Returns:

The request logger or null if no request is active, or if this is not a web application
