Sorry to sound like a jerk pointing this out again, but the Sun RPMs are
*NOT* recommended as they can be removed with an update to our stuff (I
believe it's a problem with xml Provides but I can't recall at the moment).

I installed VE yesterday using our RPMs and the update manager.  I had to
install some extra packages (ie. eveything up to and including
eclipse-pde-devel .. yum will bring in everything if you specify that ...
hmm, maybe not eclipse-rcp-devel?) but once I had them installed, I got no
errors (I think it will work even if you get "missing .../feature.xml"
errors).  Now, as for actually *using* VE ... well, it didn't work :)
There seemed to be some issue with it spawning another VM.  If someone
wants to take charge and become the Fedora VE person, I'll do my best to
help them.

Great write-up, Robin!  Can you please add some of your comments and such
to the Fedora wiki Java and/or Eclipse pages (I have the URL as the topic
for #fedora-java)?

Take a look at the various tomcat5 sub-packages as well
(tomcat5-webapps-admin, I believe, is one of them).  Often times people
will have Tomcat installed and working fine but not see anything on
localhost:8080 (or wherever) because they don't have the admin webapp
installed.
