Accessing the Struts2 Action in a JSP via tags
Hello,
I'm new to Struts 2.
Assume that I'm on a JSP that has been rendered with a Struts2 Action.
Somehow I want to access the Action and its properties via a JSP tag,
something like this:
<c:out value="${action.myValue}" />
What is the correct way to do this? Is the Struts 2 Action placed on
the request using a specific name, or is it available via OGNL? If so,
how do I access it?
Thank you!!
-Ryan

The request wrapper searches the JSP contexts first; it goes to the stack
context iff nothing can be found. So yes, if a context contains an object
with the same name it'll find that one "first".

Sort of, in the sense that it'll get searched after the normal context-based
lookup fails.

OK, so by just using:
${myValue}
The myValue property of the Action class will be accessed? I suppose
this works as long as there aren't other "myName" properties in the
other scopes, right?
I take it that Struts2 essentially exposes the action as another scope
to JSP EL?
Thank you!

Short answer:
${myValue}
Long answer:
The S2 request wrapper provides a way for JSP EL to access stack context
objects. You can also use the S2 property tag.
<s:property value="myValue"/>
