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.

the expression language (el) access them using jspcontext#findattribute().

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.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
