Tar through java

I need to tar a text file through java using the UNIX tar. I tried using the Java class to compress the file, but the .tar.gz file generated cannot be decompressed. Is there a way or command I can execute so that I use the unix os tar command to compress the files.

Will be grateful if you could provide samples.

Thanks and regards

Which one?
Use the following:

Runtime.getRuntime.exec("tar -xvf mytar.tar");

I use that tar package, and it seems to work fine :-)

Use it like Zip in java (write a TarEntry to a TarArchive object)
> but the .tar.gz file generated cannot be decompressed

?!  Then, just write the tar file through a GZipOutputStream...  that doesn't work?

It should... (and it works the other way in my app)
Bah... Tim I was ready to post the same link too :)
