Mike Boyers commented on LBCLASSIC-84:

Sorry I didn't provide initially - using version 0.9.9.

Config code is as follows.  This is the start() method for a class that extends RollingFileAppender:

    public void start() {
        // Determine the filename and location
        if (this.fileName == null) {
         // If they didn't specify a filename, we'll determine it ourselves
            this.fileName = NPlatform.getAppLogFileName();
        } else if (!this.fileName.contains(File.separator)) {
            // If we were given a file without the path, determine the path
            this.fileName = NPlatform.getAppLogDir() + this.fileName;
        // Since we've assumed responsibility of determining the filename and location, we'll
        // also assume responsibility of instantiating and configuring the rolling objects.
        FixedWindowRollingPolicy rollingPolicy = new FixedWindowRollingPolicy();
        String pattern = this.getFileNamePatternFromFileName(this.fileName);
        SizeBasedTriggeringPolicy triggeringPolicy = new SizeBasedTriggeringPolicy();

The static calls to NPlatform are used to determine the location of the logfile, I want to put it in the appropriate place for all operating systems.  On most operating systems, this will be something like ~/Library/Logs/, but for windows, this value will look something like: C:\Documents and Settings\Mike\Application Data\MyAppName\logs\appname.log

I hope this helps, please let me know if you need more information.  I should also note that I have not tried this with version 0.9.11, but would be happy to if you think it would help.

> This may be a duplicate of LBCLASSIC-56, but I wasn't sure, so I went ahead and created this issue.
> On windows, my logs failed to roll when I used a "windows-looking" absolute path when calling the rolling policy's setFileNamePattern() method.  If I use forward slashes instead of backwards slashes, it works fine.
