I found the problem. The war target doesn't add all necessary lib file. Specifically, commons-logging-1.0.1.jar was missing. I added that and it now seems to work fine.
My Tomcat version has this library (standard 4.1.12 release) so I didn't think necessary to provide it with Xindice. But since more and more people have problem with it, I will add it to the release.
