From the RH docs:
https://access.redhat.com/site/documentation/en-US/Red_Hat_Developer_Toolset/1/html/User_Guide/chap-Eclipse.html

The packages will be installed from the Red Hat Enterprise Linux 6 x86/x86_64 Supplementary channel. You need to have this channel enabled on your host for the packages to install successfully.

If you have access to the channels and are using RHN classic, you can run:

  rhn-channel -v -u redacted@domain.com -a -c rhel-x86_64-workstation-optional-6 -a -c rhel-x86_64-workstation-supplementary-6
