Problem Instantiating Session Bean
I am currently doing a Seam build with Maven2. My project is deploying just fine, but when I try to hit the project, I am getting instantiation errors. Sorry for the verbose pieces that follow, but I didn't want to miss anything. I am not sure if there is something simple that I am missing, so I wanted to include as much as possible.
