JSF Spring Integration

Question

Hi all,

I don't have much experience in J2EE development, but I have just been assigned to a project that uses JSF 1.1 and Spring 2.0. I found that many of our Spring managed service layer classes contain methods that take/return a JSF managed bean. I am wondering if this is good practice, as it seems to tightly couple the service and presentation layers. If not, what are some alternative ways of communicating between presentation and service?

Also can someone point me to a good open source project that uses these technologies so I can learn more about the best practices?

Thanks in advance!
