I am struggling with a very generic problem, which i believe most of the examinees would have faced.

If you have used JSF in your design, have you shown the Faces Servlet in the sequence diagram?

If yes, did you show all JSP events and submissions going through the Faces Servlet? I was trying to avoid this as it clutters the diagram and adds no real value, since i am not trying to show how JSF works.

In the course of avoiding to depict Faces Servlet, i am encountering a strange problem...
While it is perfectly valid to depict that a JSP calls a method directly on a managed bean, my problem arises when i attempt to show the next page rendering invocation. It is actually the FacesServlet which uses internal mechanisms to render the next page, in the absence of showing FacesServlet, would it be proper to show that the managed bean calls the next page?

Should i be showing FacesServlet?

Your views would help.How did you handle this problem.

I did not show the FacesServlet. Just document your concern as an assumption so the examiner knows you thought about it and understand that's not how it really works.
