Parameters
Usage
Use this method to send a warning message to the ColdFusion MX logging subsystem.
ColdFusion MX will write a 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).
Example
The ColdFusion MX 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(" + gat ") Unable to read configuration file
" + propsFi ": " + e.ToString() + ". Using default port.", e);
}
Parameter
Description
