I'm not sure I'm interpreting the exception properly, but it looks like JSTL is
trying to resolve javax.servlet.forward.request_uri as an XPath variable and
found it was null. It's as if you tried to do something like:
<c:set ...>
<x:out select="$javax.servlet.forward.request_uri..."/>
</c:set>
For the example you've given, it seems more like a job for XSLT (transform a
state into an option):
<x:parse doc="${applicationScope['domain.states']}" var="statedom"/>
<c:import url="/WEB-INF/xslt/stateoptions.xsl" var="xslt"/>
<x:transform doc="${statedom}" xslt="${xslt}" var="stateoptions"/>
Of course, you'd have to create stateoptions.xsl...
