Escaping EL in JSTL
Good evening,
I use Velocity to generate several Jsp pages. This works quite well as
long as I do not use EL expressions like:
<c:forEach items="${foo != null}" var="bar">
...
</c:forEach>
I tried to escape the $ sign by using a backslash or but then Velocity
stumbles upon "!=".
#set( $D = '$' ) like stated in the user-guide did not improve the
situation.
Does anybody have a clue on this ?
Maybe there is a way to exclude a whole line from being parsed by
Velocity ?
Kind regards
Marc Tinnemeyer

Thank's a lot. I guess I misinterpreted the example in the user-guide.
#set ( $D = '$' )
<c:if test=${D}{ foo != null }">
does the trick. (the curly braces seem to be important)

In the upcoming 1.7, you'll be able to do
#[[<c:if test="${ foo != null }">]]#
but for now, you have to use what we call "poor man's escaping":
#set( $D = '$' )
<c:if test="$D{ foo != null}">
Of course, it's best if you can just set the $D reference globally in
your context instead of every template. :)

Ups
the code was:
<c:if test="${ foo != null }">
...
</c:if>
