$req.session.servletContext.getAttribute(...)
$req.session.getAttribute(...)
$req.getAttribute(...)
To get parameters from the QueryString or from a POSTed form, do not use getAttribute, use:
But that's quite obvious, since $req is the request object and we all know how it works.
Example:
_test.jsp_:
<html><head></head><body>
<%
session.setAttribute("sessionFoo", "sessionBar");
session.getServletContext().setAttribute("applicationFoo", "applicationBar");
%>
<p>The following information should be available when sending the form below:
<ul>
<li>Request parameter 'querystringFoo' with value 'querystringBar';</li>
<li>Request parameter 'formFoo' with value 'formBar';</li>
<li>Session attribute 'sessionFoo' with value 'sessionBar';</li>
<li>Application attribute 'applicationFoo' with value 'applicationBar'.</li>
</ul>
</p>
<form action="test.vm?querystringFoo=querystringBar" method="post">
<input type="hidden" name="formFoo" value="formBar">
<p><input type="submit" value="Test!"></p>
</form>
</body></html>
_test.vm_:
<html><head></head><body>
#set ($ses = $req.getSession())
#set ($app = $ses.getServletContext())
<p>applicationFoo = $!app.getAttribute("applicationFoo") <code>(app.getAttribute("applicationFoo"))</code></p>
<p>sessionFoo = $!ses.getAttribute("sessionFoo") <code>(ses.getAttribute("sessionFoo"))</code></p>
<p>formFoo = $!req.getParameter("formFoo") <code>(req.getParameter("formFoo"))</code></p>
<p>querystringFoo = $!req.getParameter("querystringFoo") <code>(req.getParameter("queryStringFoo"))</code></p>
</body></html>

How do I set a request scoped object in an Interceptor and access it from a Velocity template?
I've tried every combination and find it too difficult to switch from Struts and Servlets to Webwork. The documentation could include a section which describes the application, session and request scopes in more detail. Three lines of documentation is not enough.
