How to find ALL available versions of a package in yum repository?

--I have 1.6.0-sun-1.6.0.45-1jpp.1.el5_9 version of java installed on my systems

# rpm -q java-1.6.0-sun
java-1.6.0-sun-1.6.0.45-1jpp.1.el5_9



--I need to downgrade or upgrade to specific version of java-1.6.0-sun. Now I need to find what i have in my repository.Simple list and search does not help here.

  --Command list       : show installed version and most recent version (for all arch).
  --Command search : shows all package matching with search string - demo, develp, src, jdbc etc.


# yum list java-1.6.0-sun
