[Stripes-users] ActionBean and PageOnLoad
Hi, I am using stripes layout to create a 'master page' of sorts. One of the layout component (the 'header' layout) is responsible for rending the horizontal tab menu on the page. Since this is the header, it appears for all pages of course. I need the tabs that are displayed to be dynamic based on user roles. For instance, If a user is Guest vs a Registered User, the tabs will be different. If a user is an Administrator, an Admin tab will show. etc. My base actionbean has a method that that delegates to a SecurityService that can determine which roles a user has. The issue i'm having is how to do this the 'right' way. Right now, when you first land on a page, it does not appear as though there is a way to invoke an actionbean method. This seems to happen only if you submit the page or if you use a url that is bound to the actionbean (i.e. /MyActionBean.action). It seems as though the ActionBean does not really come into scope until that happens. Is there away to make an actionbean come into scope when a page is first loaded? Is there away to bind an actionbean to a stripes layout component such that, in the case described above, that action bean will always be available to the web application (given that the header is always displayed)? If i can do that, i figure i would have what i need to solve the problem. Are there other ways anyone can recommend to solve this problem? thanks, Mike -- The Next 800 Companies to Lead America's Growth: New Video Whitepaper David G.

Re: [Stripes-users] ActionBean and PageOnLoad
Mike,
What you are looking for and more is covered in Freddy Daoud's book on
Stripes.
The mechanism you are looking for is as follows:
s:url var=url
beanclass=org.test.ui.web.action.view.support.MenuViewHelper
prependContext=false
s:param name=currentSection value=${currentSection} /
/s:url
jsp:include page=${url} /
There is a lot happening there so have fun... and get the book (it goes
into more detail on how the sections can be represented using enums and
localization and more)... its well worth it... .

Re: [Stripes-users] ActionBean and PageOnLoad
Nice. I had actually ordered that book this morning before even posting my
question. I was hoping for a solution before the book gets here however.
In my case i'm not really trying to build a menu, but rather tabs. To do
that, i feel i need a way to be able to reference an actionbean from the
layout component that is always visible and when pages are loaded rather
than submitted. That way i can either call a method on the actionbean to
determine if the current user is entitled or not to view certain areas of
the page.
Not quite sure yet how to do it.

Re: [Stripes-users] ActionBean and PageOnLoad
Mike,
MenuViewHelper is an ActionBean (sorry if the name is a little
deceiving). s:url constructs a URL to the ActionBean and the
jsp:include includes the ActionBean which essentially processes the
default handler on the ActionBean and forwards to a a JSP.
Instead of building a menu in the JSP do whatever you like with your
tabs and authorization. It really doesn't matter whether its a menu or
tabs its the idea that is key i.e. what I gave you was the key part
which is how to inline / embed the output of the view of an ActionBean
inside a JSP.
Simply place the block I gave you below within a layout-component tag in
a nested layout and render and voila you are golden.
What do you feel is still missing?
