I'm working with a Security Manager class and I'm putting together lists of library files for the various operating systems. Windows uses dll files, while Unix/Linux uses so files. These library files are typically found in the JRE lib directory. However, I'm not familiar with the Mac operating system. I don't know what the file extension is for Mac library files. Could someone, who has a Mac, please go into your JRE and provide me with the complete list of library files that reside in the lib directory. I'm assuming the JRE for Mac even has a lib directory.
