If it is occurring when you 'run project' from within NB, then you may want to connect with the NetBeans user mailing list. Additionally, if the application functions properly within NB but blows up when you deploy the .war file, the same applies. Occasionally, there can be intricacies with deployment internally as opposed to externally. Usually, in my limited experience, this is because of difficulties in properly specifying the location of libraries.
