warnDescriptionWrites a log entry with a warning severity to the ColdFusion logger. The entry includes the severity, thread ID, date, time, and a text message. See alsodebug, error, fatal, info, getLogger, Logging events and using log files in the Developing ColdFusion Applications Parameters
UsageUse this method to send a warning message to the ColdFusion logging subsystem. ColdFusion writes messages with a severity of “warning” to the log file specified in the getLogger method that returned the Logger instance (or the default log file). ExampleThe ColdFusion example SocketWatcherGateway class includes the following code in its constructor to load a configuration file. If it cannot load the file, it converts the exception information to a string and logs a warning that includes the gateway ID, and the exception information. It also passes the exception to the warn method propsFilePath=configpath; try { FileInputStream propsFile = new FileInputStream(propsFilePath); properties.load(propsFile); propsFile.close(); this.loadProperties(); } catch (IOException e) { // do nothing. use default value for port. log.warn("SocketGateway(" + gatewayID + ") Unable to read configuration file " + propsFilePath + ": " + e.ToString() + ".Using default port.", e); } |
