[newbie] problems installing runtime environment file from Sun

[tazmun]

Hi All   I am very new to Linux and the command line is very intimidating yet.  I have downloaded a supposedly self extracting file (.bin) as well as the rpm version of the file.  They suggest in the install directions that this be done from the command line and tell you that by using a command(./) on both of the files will start a script asking if you agree to their agreement first.  This command on either file just gets me a permission denied error whether I'm logged on as a user or as root.  This file is to install the runtime java enviroment required by Staroffice for any java applications to function.  The file will not run in kpackage in the rpm version either......if you try to execute it it will error and say  is it not  executeable.  I am running Mandrake 7.1 for now.  I've also tried the rpm -ivh and -iv commands to no avail either.....help please.....I hate the Redmond gang but this is driving me nuts too!!    Anyone helping here please assume I know nothing of the command line in their directions.    Tazmun
