Re: getting list of all context values

[Charles Harvey III]

Ok.  I tried this out.  And it works... sort of.  There are definately
things missing and I can't figure out why.

As in, I know for sure that I am doing:

   request.setAttribute( "person", person );

And "person" isn't in the list of $request.attributeNames.  I can't for the
life of me figure out why though.  Is there something I am missing?  This
is what is getting printed to the page for the $request.attributeNames:

# javax.servlet.forward.request_uri
# javax.servlet.forward.context_path
# javax.servlet.forward.servlet_path
# javax.servlet.forward.path_info
# org.springframework.web.servlet.DispatcherServlet.THEME
# __acegi_session_integration_filter_applied
# org.springframework.web.servlet.DispatcherServlet.CONTEXT
# __acegi_filterSecurityInterceptor_filterApplied
# org.springframework.web.servlet.DispatcherServlet.LOCALE

What is even stranger is that it works for the session.  
$session.attributeNames:

# website
# IS_USER_ONLINE_SESSION_BINDING_LISTENER

Those are definately two values that I specifically put into the 
session.  All
I can think of is that Spring is doing something to my objects and I guess I
have to go figure out what.

By default, the context is not included in itself, but you can still
list the values in the session, request or response (or also in the
servlet context, known as "application") with the following loops:

#foreach($key in $request.attributeNames) ...

#foreach($key in $session.attributeNames) ...

#foreach($key in $application.attributeNames) ...


If you need the context to have a key towards itself, you have to
subclass the VelocityViewServlet, and inherit createContext like this:

    protected Context createContext(HttpServletRequest request, 
                                    HttpServletResponse response)
    {
       Context context = super.CreateContext(request,response);
       context.put("context",context);
    }


You can then iterate on values of the context like this:

<ul>
#foreach($key in $context.keys)
<li>$key = $context.get('$key')
#end
</ul>

but the values in the request, session, response and application won't
appear in this list.

Hello.
If I am using the VelocityLayoutServlet where all things that I put into
the request, response and session automatically go into the $context.

So... how do I get a list of all the values in the $context?  Just for
starters, how do I access the $context?  It is not with "$context".

I can access $request, $response and $session.  So, how do I get at the
$context?

Thanks much.
