No. The example was just trying to say that 'varName' is a variable which
the value of the variable contains the name of the variable to lookup.
The example was meant to explain this (but I obviously failed). Here's
another go..
<j:set var="varName" value="some.file.property"/>
So ${varName} will now output 'some.file.property'
<j:set var="filename" value="${context.getVariable(varName)}"/>
which is equivalent to
<j:set var="filename" value="${context.getVariable('some.file.property')}"/>

Unfortunately not. Though Jexl should be a superset of the expression
language in JSP - so maybe the JSTL documentation might help?
