Logger question

Hi all,
I have a program with multiple processes. Each process spawn multiple threads. If I want each process to have a unique log file name (all threads associated with a process should write to the same log file), how would I go about doing this to gaurantee uniqueness?
I am mostly looking for setting the name of the log file dynamically in my program rather than using file. Since I want each process to be able to specify its name as part of the logger name. For example if there are 3 processes in the system named two Servers and Client, log names should be something like:
Thank you,

Here is how I am doing it using file:
# default file output is in user's home directory.
java.util.logging.FileHandler.pattern = %h/java%u.log
java.util.logging.FileHandler.formatter =
java.util.logging.FileHandler.append = true
java.util.logging.FileHandler.level = FINE

Now, the log file names are all unique, but are names java0.log, java1.log, java2.log. If there is a way to somehow change the above pattern to include the name of the class that starts the process, it would be great.
It is sorta covered in the JavaRanch Style Guide.
