I have the following JSTL code that puts an XML document into the
pageScope. The <state> tag can be found at
http://www.servletsuite.com/servlets/statetag.htm and is basically a
<select> with all the states as options. I want parse the options and
compare their values with a comma-delimited list of states from a bean
in the request. That's later - first I want to just get the list of
states and display them using XPath.
<c:set var="statesHTML">
<state:state name="state" default="<%=state%>" />
</c:set>
<x:set var="states" select="$statesHTML"/>
This all works fine - and I can print out the states using:
<c:out value="${pageScope.states}"/>
Which results in:
<select name="state"> <option value="AL">Alabama</option> ... </select>
However, if I try to get the <options> with XPath and loop through them
with <x:forEach>, I get the following error. Here's my code for
obtaining that information:
<x:forEach var="state" select="$states/select/option/*">
<c:out value="${state}"/>
</x:forEach>
java.lang.ClassCastException
