I cannot ust CDI

[miss_duke]

In order to enable CDI in my project I created beans.xml file, and then tried to deploy my project (not yet used any CDI related coding), but I get the following error. If I delete the beans.xml, my project is deployable without any problems. (I use Nertbeans 6.9 and Glassfish 3.0.1)
