IncludeResourcesTag doesn't work in 3.0-trunk
---------------------------------------------

                 Key: JSPWIKI-641
                 URL: https://issues.apache.org/jira/browse/JSPWIKI-641
             Project: JSPWiki
          Issue Type: Bug
          Components: Default template
    Affects Versions: 3.0
         Environment: All
            Reporter: Andrew Jaquith
            Assignee: Andrew Jaquith
            Priority: Minor
             Fix For: 3.0


This is a note to self to fix IncludeResourcesTag and RequestResourceTag so that they work in 3.0. Current 3.0 trunk builds don't support adding arbitrary resources because I removed JSPServletFilter.

----- note from jspwiki-dev thread ------

While I continue to feel that it makes more sense to use the Stripes layout tags, we could make the IncludeResources and RequestResource tags work if we did the following:
* When a RequestResource tag is encountered, stash the requested content into the request as an attribute
* When the IncludeResource tag is encountered, retrieve the attributes and send to the output stream

This could work nicely in 3.0 because of how we separate the layout JSPs from the content JSPs. The content JSPs are processed before the layout JSPs, which means RequestResources tags always execute before the IncludeResources tags.

So, this would be pretty simple to implement, and it would not require a response wrapper. The code that requests and renders the resources would be private (inside the tags), and thus restricted to JSP authors who used the tags in their JSPs. That would satisfy my concerns about safety -- my chief concern was the public access to the resource request API by plugins. Plugin authors could always muck around with request attributes if they wanted to inject their own resource requests, but it would be clear that they were "off the reservation" at that point.
