First of all, there is no guaranteed way of doing this, as the class
might be loaded over the network and not exist anywhere on the local
disk.
However, if your code is privileged,
getClass().getProtectionDomain().getCodeSource().g etLocation() returns
a URL which is the equivalent of a classpath entry. That URL might
refer to a directory, a jar file or something else and could be on the
local machine or remote.
I don't see the original message with the original question. If all
you want to do is load a .properties file or an image or something
relative to the class' location, then Class.getResource and
ClassLoader.getResource are better approaches.
Good luck.
Note that I don't check this group often, and so see or respond to
follow up posts.
