I suppose from remaining of email, that you mean the html resulting from
the above jsp is shown, not the jsp content unparsed.

Internal server redirect, the url is not changed because client is not
aware of this redirect.

It seems your form is submitting to 'index.jsf' instead of 'enterAge.jsf'

This part is normal. Your jsf form was submitted to enterAge.jsf. That's
why you see enterAge.jsf in url. However, after action execution, jsf
got instructed to display content of result.jsp (according to navigation
rules) and that's what it does.

jsp:forward is all internal. In general, jsp tags do not mix very well
with jsf :) In your case you are under a jsf context (you accessed
index.jsf) which then write down a few datas (like the viewId=index.jsp)
before asking the index.jsp to render, which itself redirect work
enterAge.jsp, but for JSF, this is the index.jsf view, and that's where
the submit will go, and that's where the navigation rules will be looked
for.
solution, do the opposite,
access index.jsp, which forwards to enterAge.jsf, which jsf handle and
write down the viewId (enterAge.jsp) before asking enterAge.jsp to render.
