rmps over a network

Im using Nymph thin client. I need to install java on to the servers and the only way i have of doing this is either ssh or vnc. I have the rpm of java but have no idea how to make it work only using the command line. I tried ./(filename) and got permission denied error. Although im root when i do this it shouldnt matter should it? Is there a command or switch im missing. Im sure its someththing very simple but im new to this. Ive only been us linux about 3 weeks. Any advice is welcome. Cheers -- Andrew Nix St Pauls Catholic High School Firbank Road Newall Green Wythenshawe Manchester M23 2YS tel: 0161 4375841 ext 168 fax: 0161 4982030
