The weird thing is that there is no ovirt-optimizer.log (it should have been there because of deployment descriptor that is present in /usr/share/java/ovirt-optimizer/jboss.war/WEB-INF or thereabout).

I didn't mention yesterday that I was testing it on my env with a 
cluster and I got the same 404. only after rebasing and using the latest 
I got it fixed.

the optimizer is indeed working. the resteasy for some reason didn't 
like the domain/result/clusterId path
