I see. The outputText way is actually what I did. So, is there a way to call
a method in the backing bean when/before loading a JSF page? Something like
a pre-render method before loading a JSF page? I can do that in the backing
bean methods that forward to the JSF page, but there are many places that
could forward to that JSF page. That's why I trying to do it in the JSF page
itself.
thanks

Yes, commandLink and commandButton will render an anchor tag. If you
don't want to do this you can do work in your properies getter method
when it gets called by outputText value and return an empty string.
However, I don't believe there is any guarante as to call order.
Putting your target outputText in the first line of your jsp file
doesn't mean it will get called before other getter methods further
down in the jsp file get called.

Thanks for your reply, that makes sense. But won't h:commandLink render a
link and h:commandButton render a button in the page? I don't want to
display anything on the screen. My purpose is to initiate a call from the
JSF page to a method in the backing bean when the JSF page loads. I'm
returning an empty string from the method so nothing gets printed out
from
<h:outputText>.
