Do you mean Eclipse 4.2? Eclipse 4.3 is part of the Kepler release for June of 2013 and there is no OEPE support for that version yet.
Eclipse 4.2 is a less stable platform than Eclipse 3.8, which has all of the same features. There are no plans to produce OEPE distros with Eclipse 4.2, but the combination is supported and tested by Oracle. For best results, start with Eclipse IDE for Java EE Developers distro that you can find on the eclipse.org download site. Installing OEPE into a different distroy can be more difficult due to unsatisfied dependencies.
We will start producing OEPE builds on Eclipse Kepler Milestone releases next year (in the past it has been around the March/April time frame) but whether this will be on Eclipse 3.x or 4.x is still being evaluated.
Second I tried to install via update
NOTE: There is no http://download.oracle.com/otn_software/oepe/kepler
When tried to install OEPE JUNO via update I got this dependency error:
Cannot complete the install because one or more required items could not be found.
Software being installed: Oracle WebLogic Server Tools 18.104.22.168211211917 (oracle.eclipse.tools.juno.weblogic.feature.group 22.214.171.124211211917)

I have real development to do at work.
I am switching back to Eclipse Juno OEPE all-in-one-bundle.
I don't have time to figure out how to make Eclipse Kepler work with OEPE plugin.
I like the new UI I see in Kepler. And I am excited to use Kepler once the OEPE plugin can work with Kepler.
We use WebLogic and I need to use the OEPE so I can start and stop WebLogic.
I hope you make OEPE available on the 4.3 branch since that seems to be the one with the new UI.
