This is about gzip (which is gnuzip, as I understand):

There seems to be a lha decompressor beta on source forge

It looks like ther is no much on other formats, I guess there is something also about .rar - you didn't mention it in your list

Maybe you'd be better off trying to use the system tools using Runtime.getRuntime() - I think
even in UNix envirronemnt  you can find tools without source code and not in Java

There's no 'one size fits all' app that does this in Java. Not even in Unix probably, since it's against the grain of the Unix 'philosophy'. You'll need to install the app that performs the correct functionality for each archive and call it from Java

For any formats that you cannot locate a java library for you can use Runtime.exec() to call a command line utility to perform the decompression. Make sure you consume any generated from the process to avoid it locking up

Okay ..Thanks for all your comments on this. Now my query is

I am creating a java program and it uses the below utility to uncompress the file types (.arc,.arj,.cab,.lha,.zip,.compress,.gnuzip)


Does all the above utility is compatible with Unix also ? If not what are the substitute for these utility in Unix ?
