Where can I find Java EE examples that are more complex?

Paraphrased from the users@glassfish mailing list:

Q. I am a good Java developer but I am new to J2EE and GlassFish. I have been looking at examples and have done all the tutorials, but I have not been able to find a more complex example. How do we take advantage of stateful beans in complex data processing scenarios? I am specifically interested in user sessions, and how we use stateful beans to interact with one user per bean.

A. You may want to look at the GlassFish Samples page, which has a few samples on EJB 3.0. All of the samples are NetBeans projects and work with NetBeans 5.5 or later. Please refer to the samples documentation for use or any issues. Also take a look at Java EE blueprint applications.
