About: The second Note in 3.1.1 gives information about using the alternatives command to add JDK.

Issue: These instructions did not work for me using alternatives version 1.3.59. I made the assumption that each sudo command should be input separately so perhaps this is where I went wrong. The use of the given commands, with jdk1.6.0_24 changed for update 37, resulted in the instructions for using the alternatives commands being output on the command line as below:

--------------------------------------------------------------------------
{noformat}[mmurray at dhcp-0-244 ~]$ sudo /usr/sbin/alternatives --install "/usr/bin/java" "java" "/usr/java/jdk1.6.0_37/bin/java"
alternatives version 1.3.59 - Copyright (C) 2001 Red Hat, Inc.

usage: alternatives --install <link> <name> <path> <priority>
                    [--initscript <service>]
                    [--slave <link> <name> <path>]*
       alternatives --remove <name> <path>
       alternatives --auto <name>
       alternatives --config <name>
       alternatives --display <name>
       alternatives --set <name> <path>

common options: --verbose --test --help --usage --version
                --altdir <directory> --admindir <directory>{noformat}
--------------------------------------------------------------------------

Workaround: To get the instructions to work, I added a priority number to the end of each 'alternatives install' command as per the alternatives man page. For example,
{noformat}sudo alternatives --install "/usr/bin/java" "java" "/usr/java/jdk1.6.0_37/bin/java" 2000{noformat}

{noformat}sudo alternatives --install "/usr/bin/javac" "javac" "/usr/java/jdk1.6.0_37/bin/javac" 2000{noformat}

{noformat}sudo alternatives --install "/usr/lib/jvm/java-1.6.0" "java_sdk_1.6.0" "/usr/java/jdk1.6.0_37" 2000{noformat}

I was unsure what number to pick for the priority and randomly put 2000. I ran each sudo command separately.

Also, it appears that the quotation marks are not necessary in the command.
