JBoss Seam, EJB3.0, JBoss Tools, Hibernate Error Messages

I recently started self-learning JBoss Seam, along with Hibernate, EJB3.0, JPA, Annotations, EL, and everything else that goes with it. My prior experience included Java, JSPs, and XML, so it's been a steep learning curve. It was a definite struggle to get the first five or six entity beans, session beans, and pages built. It seems that every time I add something to my project, I run into a new error which takes between 2 and 8 hours to resolve.

In an attempt to help others who might have the same issues AND also to track this information for my own purposes, in case I run into the same problems again, I am documenting the problems I've had and the resolutions to those problems. I make no guarantees for whether my resolutions will solve your problems. However, the resolutions listed did solve the specified problems for me.

This is a living document. I will add problems/resolutions as I encounter them. I will be happy to attempt to answer any questions you leave me in the comments and encourage anyone to add/modify/correct any information that is incorrect or lacking. I will incorporate such helpful suggestions left in comments into the main body of the blog entry.
