Subject Re: getting list of all context values
Date Wed, 18 Oct 2006 08:43:25 GMT
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.
