Scripts are raw java embedded in the page code, and if you declare variables in your scripts, then they become local variables embedded in the page.
In contrast, JSTL works entirely with scoped attributes, either at page
, request
or session
scope. You need to rework your scriptlet to fish test
out as an attribute:
<c:set var="test" value="test1"/>
<%
String resp = "abc";
String test = pageContext.getAttribute("test");
resp = resp + test;
pageContext.setAttribute("resp", resp);
%>
<c:out value="${resp}"/>
If you look at the docs for <c:set>
, you'll see you can specify scope
as page
, request
or session
, and it defaults to page
.
Better yet, don't use scriptlets at all: they make the baby jesus cry.
