Hi friends, What is RAR file in j2ee. Please give me directions to creatre RAR files.
Please help me.

Thnaks & Regards

RAR files have nothing to do with Java. They are multi-part archives that can easily be rejoined to create the original file, or file set. There are a number of free applications that can generate or extract rar sets, both for Windows and Linux; however, they have to license the code from Alexander Roshal, so they really aren't open source (as in FOSS). Here is the wikipedia article with a lot of information that may help: http://en.wikipedia.org/wiki/RAR

As far as I know, if you want to create a Java implementation, you will have to license and obtain the code from Roshal.
