EL equivalent of pageContext.getAttribute( aVariable )

[Agoston Bejo]

Hi!

I have a variable the value of which is a key to look up a value the way pageContext.getAttribute() does (i.e. going through the page, request, session, application scopes in a row). So the main point is that the value of the lookup key can VARY, it's not constant. (Otherwise I could say ${LookupKey} and that would be it.)

I.e. something like this:
<c:set var="theKey" value="LookupKey"/>
<c:if test="${pageContext[theKey]}"> ...

the above syntax doesn't work, of course (otherwise my question would've been automatically answered ), it's just a pseudo-code for you to get the idea.

Thanks!

I think I see what you're after... you want one level of indirection and you want all scopes to be automatically searched. I'm afraid you can't have both.

For a scoped variable whose name is within another variable, you'll need to know what scope the variables is stored within and use syntax like:

 ${requestScope[theName]}

P.S. I think that it's the PageContext.findAttribute() method you were referring to.

Yes, I was after that, and am sorry to hear that it's not possible.
And yes, I meant PageContext.findAttribute().

And what I actually wanted to say was: thank you!
