This may be a FAQ, in which case I apologize, please point me in the right direction. Situation: While I like to think of myself as technically reasonably savvy, I know absolutely nothing about Java, JREs, JDEs, JVMs, or other TLAs that start with J. (I've never even watched _JAG_ :-) I'm trying to install oXygen onto an Ubuntu 9.10 system. I downloaded the "Linux 64 bit (Includes Java VM 1.6.0_16)" .sh file from http://www.oxygenxml.com/download_oxygenxml_editor.html. The instructions say "Make sure you have in your PATH environment variable the correct location of the JRE." How do I know the location of the JRE? I tried executing the oxygen.sh command, but got | syd@Nimbus2000:~/Downloads$ sudo sh oxygen.sh | [sudo] password for syd: | Unpacking JRE ... | Preparing JRE ... | bin/unpack200: 1:ELF: not found | bin/unpack200: 4: Syntax error: word unexpected (expecting ")") | Error unpacking jar files. Aborting. | You might need administrative priviledges for this operation. | syd@Nimbus2000:~/Downloads$ [Note that there is an unprintable character that didn't survive the cut & paste -- perhaps a U+007F? -- in front of "ELF".] Is this because I don't have the right JRE in my $PATH (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games)?
