Accessing set variable in Java as String [message #44575]

My input looks like this:

<data>
<wrap>
<in package="com.foo" name="Foo"/>
<out project="my.proj" package="com.bar" name="Foo"/>
</wrap>
...
</data>

Here is my template fragment:

<c:iterate select="/data/wrap" var="wrap">
<c:setVariable var="interfaceName" select="$wrap/in/@name"/>
<%
String interfaceName = (String)context.getVariable("interfaceName");
%>
</c:iterate>

When I try to run this code I get a casting exception. It is returning a
NodeSetImpl rather than a String.

Try:

<c:setVariable var="interfaceName" select="string($wrap/in/@name)"/>

XPath expressions like $wrap/in/@name don't actually return strings, they
return 'nodes' in the input model. Most of the time, JET converts these to
strings for you.
