Parameters

Parameter	Description
logfile	The name, without an extension, of a log file in the ColdFusion logs directory. ColdFusion automatically appends a .log extension to the name. If the file does not exist, ColdFusion creates it when it logs the first message. By default, ColdFusion logs to the eventgateway.log file.

Returns

A ColdFusion logger object

Usage

The Logger class has five methods: debug, info, warn, error, and fatal, that correspond to the severity level that is set in the log message. Each method takes a message string, a Throwable class object, or both.If you pass a Throwable object to these methods, ColdFusion writes the exception information in the exceptions.log file.

Example

The ColdFusion example DirectoryWatcherGateway includes the following line in the constructor to get a logger object:

// We create our own log file, which will be named "watcher.log" logger = gatewayService.getLogger("watcher");

The following code, from the start of the routine that loads information from the configuration file, uses this object to log the initialization.

// Load the properties file to get our settings protected void loadconfig() throws ServiceRuntimeException { // load config logger.info("DirectoryWatcher (" + gatewayID + ") Initializing DirectoryWatcher gateway with configuration file " + config); . . .
