Your message carries no introduction or background information other
than the obvious, so I'll try to address that.  Are you running stable
versions of the Java packages, or are you running ~arch for any of them?
What versions are you running of:

      * java-config-1.x
      * java-config-2.x
      * java-config-wrapper

Have you synced Portage in the last day or so?

Before going any further, you need to fix your problems with your Java
environment.  Don't bother trying to emerge eclipse packages or anything
else based on Java until this is resolved.

Have you read and followed the instructions in the Java Upgrade Guide?
http://www.gentoo.org/proj/en/java/java-upgrade.xml

It appears that there are problems with your environment pointing to the
wrong (a missing) Java runtime.  If you've followed all of the steps in
the guide then report back and we'll help you from there.
