Installing jboss-3.2.3

[binnyms]

Hi,
I have downloaded jboss-3.2.3.tar.gz and when i try to unzip it in solaris it is giving "tar: directory checksum error" . I fact I have removed the .gz using winzip and I am extracting the .tar file
using tar xvf jboss*.tar

what could be the problem
thanx in advance

Try using the GNU version of tar available from sunfreeware.com
