logFile property
This property determines where log messages are stored.
The property value can either be a file name or the special identifier
<stdout>.
If you specify the special identifier <stdout>, logging is directed to
standard out. In this case, the logging typically appears in the web application server's log files.
Any other value is assumed to be a file name and the logging information that is output during
operation is stored in the specified file. The file name can be an absolute path or a relative path.
Enter any backslashes (\) as a double backslash.
If you leave the value blank or if the property is not specified, then logging messages are
output to the <stdout>.
Example
logFile=c:\\viewer\\viewer.log
logFile=<stdout>
