Way to compare scoped value to a class constant variable?
I'm wondering if there is a way I could compare a scoped variable to a
static constant variable that is in a class?
For example in Const class I have some levels like:
public static final int JVP_LEVEL = 3;
It would be nice if in my JSP I could do (after the import up top)..
<c:if test="${myScopedVar == Const.JVP_LEVEL}" />
I know I could just do ..
<c:if test="${myScopedVar == 3}" />
But it is clearer in the code to use the Constant name. Is it possible
to do this somehow?
Thanks,

Killer! I'll have to check this out right now.

Unsure if JSTL 1.1 will allow this, but using the Unstandard taglib you
can do:
<un:bind var="bob" type="your.package.Const" field="JVP_LEVEL"/>
<c:if test="$myScopedVar == $bob">
..
</c:if>
