I've been able to do some (painful/strange) debugging with NetBeans - it seems that both serverVersion and commonVersion are null in EngineStarter.java line 145.

Hi Ernst,
Not sure whether anyone else has had the chance to try this - the problem is probably just with me. I took the Xins source code and extracted it to an XP machine.
I'm using java 1.6.0_12. I was able to build it straight off from using ant.
However, going through the primer, it fails when I try to run-myapi - I get the following:

C:\dev\znerd-xins-1225133\MyProject>xins -Dorg.xins.server.config=xins.properties run-myapi
