Hi All, I am relatively new to both Linux and Fedora 5 x84_64 and I can't seem to get the tools of the Sun JDK working via command line. The installation of the JDK seemed to go fine. Typing: [root@localhost ~]# java -version Produces: java version "1.5.0_07" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03) Java HotSpot(TM) Client VM (build 1.5.0_07-b03, mixed mode, sharing) (The Sun JDK package was installed not just the JRE....in theory anyway :) However typing: [root@localhost ~]# jar -V produces: jar (fastjar) 0.92-gcc Copyright 1999, 2000, 2001 Bryan Burns Copyright 2006 Free Software Foundation.......... Then typing: [root@localhost ~]# javac produces: Eclipse Java Compiler v_585_R31x, 3.1.2 release, Copyright IBM Corp 2000, 2006. All rights reserved. Typing: [root@localhost ~]# appletviewer produces: bash: appletviewer: command not found As you can see the problem is simply Sun JDK is not the default! How do I make the Sun JDK the default? Which environment/configuration file do I modify? Thanks! Russ Kinter
