Lutz, Servoy "shields" you from having to actually dive into or know anything about Java, but its there in the background (and can be used if you so desire). As you stated, you would use more Javascript than actual Java code normally if desired.
Here is a couple write ups on Servoy in eWeek (little old but good overview) that gives you an idea of how it works and how it is setup to shield you from Java, etc.

>>Neil, I also have the Servoy Developers license.

>>Question for you: did you know Java before Servoy, or are you even bothering to learn or directly use any Java in addition to what Servoy does?
