Hello mates,
I?ve been looking for this question in the forum, but as I?ve not found a
response for it I expose my doubt here.
I?ve been working successfully till now with EJB3 and JSF, and now I want to
try Seam. So, I?m reading the Seam Tutorial and there is a sentence that I
can?t see quite clear : Most Seam applications use session beans as JSF action
listeners.
There is the Example 1.2 below this sentence :
public String register() {
List existing = em.createQuery("select username from User where
username=:username")
.setParameter("username", user.getUsername())
.getResultList();
if (existing.size()==0) {
em.persist(user);
log.info("Registered new user #{user.username}");
return "/registered.jsp";
}
else
{
FacesMessages.instance().add("User {user.username} already exists");
return null;
}
}
My doubt is that if I work in this way I tie my business tier to my view tier,
so I can?t reuse my business logic in standalone applications, for example. I
know that Seam was created in order to work with web applications, but anyway I
think that it?d be a better practise to develop SLSB without mixing it with web
code, and on the other hand, develop a JSF action listener that use the SLSB.
Don?t you think that this is a better structure or is there something that I ?m
not understanding?
Thank you for your explanations.
Best regards,
Jose Luis Monteagudo
