eclipse, eclipse-jdt and what else?

[Oliver Ruebenacker]

     Dear friends,

  I have installed Fedora 7's java, eclipse and eclipse-jdt, but
Eclipse complains it can not resolve a lot of things, including
java.io and java.lang. Which packages might I be missing?

  Thanks!

     Take care
     Oliver
