Using JSP 2.0 XML tag file that contains a scriptlet. The scriptlet set
a page attribute of type Bar. I can now use "bar" in EL expressions on
page that uses this tag. QUESTION: do I have to pass in the pageContext
as an attribute to do this?
<%@ tag body-content="empty" %>
...
<jsp:directive.attribute name="foo" required="true"
type="com.acme.Foo"/>
<jsp:directive.attribute name="ctx" required="true"
type="javax.servlet.jsp.PageContext"/>
<jsp:scriptlet>
ctx.setAttribute("bar", foo.getBar());
</jsp:scriptlet>
Side question: after setting the attribute, "bar" cannot be accessed
within the tag itself, e.g., ${bar.status} complains it cannot find
bar. It's as though it is evaluating the EL before the scriplet runs.
