java - Which variables can be accessed with the ${...} syntax in a Struts tag in a JSP page? -

i'm getting little bit frustrated since can't find out variables can access ${...} syntax in struts tag, placed in jsp page.

as example i've got following code:

<c:set target="${status.menue}" property="activemenuepath" value="whatever" />

where object "status.menue" have defined in order can accessed dollar sign , braces. defined in struts tile or in form?

it should placed in of page, request, session or application scopes using respectively jspcontext#setattribute(), servletrequest#setattribute(), httpsession#setattribute() or servletcontext#setattribute(). either directly or indirectly inside servlet. mvc frameworks indirectly, configureable giving model object "request", "session" or "application" scope.

this way unrelated struts. it's legacy mvc framework built on top of jsp/servlet api. <c:set> not struts tag well, it's jstl tag.
