Reading RAR file

[Ankur Luthra]

Hi,
I am trying to find checksum of all class files in a archive (zip /rar)
I have a method which takes Input Stream as input and returns checksum for the class.
I am able to read the zip archive using ZipInputStream ,ZipEntry and ZipFile classes but somehow not able to read rar files.
I came across few 3rd party jars which claim to read Rar file(RaroScope.I guess that was the name).
Just wanted to know if I can do it in Java.
I am using below code .The second line returns null in case of rar file but it returns an entry in case of zip file

ZipInputStream zs= new ZipInputStream(new FileInputStream("D:\\TestInput.rar"));
			
			ZipEntry ss=zs.getNextEntry();

Kindly provide me with some suggestions.

RAR is not ZIP, so it's no wonder that this doesn't work. The standard Java compression library (Apache Commons Compress) doesn't handle it, either, so you'll have to use a 3rd party implementation like https://github.com/edmund-wagner/junrar

Thanks Dittmer for your advice :-)
