How to run Sonatype Nexus repository on Eclipse Virgo server?

I find it very weird I couldn't find anything useful googling for this so that's why I'm trying here: Could someone please explain to me how I can install Sonatype Nexus repository on Eclipse Virgo server?

I tried on my linux (ubuntu server) and windows machines but both gave me the error on pasted down below when server started. (so I just dropped the war in the picked folder)

Thanks a lot in advance folks!

EDIT: Cause probably is related to: Exception sending context initialized event to listener instance of class org.sonatype.nexus.web.NexusBooterListener

I was able to filter a more specific error message in DEBUG log mode:

Tried same Nexus version on Tomcat 6 -> had to remove serverlet lib from war -> tried same war once more on Virgo and I seemed to get a similar error message:
