Examples of org.apache.roller.business.FilePathException

org.apache.roller.business.FilePathException
Thrown from the FileManager if a file path is considered invalid for some reason, like it represents a directory instead of a file.

        // get a reference to the file, checks that file exists & is readable
        File resourceFile = this.getRealFile(weblog, path);
        
        // make sure file is not a directory
        if(resourceFile.isDirectory()) {
            throw new FilePathException("Invalid path ["+path+"], "+
                    "path is a directory.");
        }
        
        // everything looks good, return resource
        return new WeblogResourceFile(weblog, path, resourceFile);
