To explain my confusion:
I wanted to make NSF update site to ease install procedure for both server and designer. I have imported domino update site from redist folder and did not copy other jars (I try to avoid copying files directly - it is hard to celan it up after a while).
My solution is to import site.xml from both SBT SDK and XPages Bazaar update sites into single update site database. It works and it is much easier to deploy.
P.S.: thanks for really quick reply ;-)
