Find the conf file no matter how the application was launched

I am new to java.

I have a directory structure

  product/
        conf/
        classes/com/../..

conf/contains the configuration file, and in classes/I have my application.

How can I ensure from internal java code that I can find the file in conf/, even though I execute it (for example, from eclipse, from different directories, from crontab, etc.).

PS

Files in conf/are not resources, as they must be edited by the user. Is there any way to find out where mine is .class, so I can use the relative path for this directory to access my directory (e.g. MY_CLASS_DIR /../../../../ conf)
