How to log to a regular file without using levels (warn, info, etc) ?

[Rebecca Ahlvarsson]

I am interested in using log4j for audit logging, in other words, I will
open my own file and start logging anything I want. Therefore I do NOT want
to use warn, info or any log level. Something like that:

Log log = new Log("blah.txt");
log.log("Test");
log.close();

How can I do that with LOG4J?

A concrete example that I can run will be very appreciated.

Thanks,
