netbeans, can't deploy web project

Here's a (simple) project that should demonstrate spring mvc + jsf 2. I just can't load it in Netbeans; i tried to create a new project, add the sources in the web directory. N开发者_运维技巧B gives me an error: build-impl.xml:669: The module has not been deployed. It seems that the ant script couldn't manage this project. thanks ps. I use netbeans 6.9.1 Here's the log:
