I tried to evaluate string.toUpperCase() in the
following jsp,
<%@ taglib prefix="jx"
uri="http://java.sun.com/jsptl/ea/jx"; %>
<html>
<head>
<title>JSPTL</title>
</head>
<body bgcolor="#FFFFFF">
<%
String c = "bbbbbbb";
request.setAttribute("b", c);
%>
<%-- <jx.expr value="$b"/> works fine --%>
<jx:expr value="$b.toUpperCase()"/>
</body>
</html>
And got translation error,
javax.servlet.ServletException: Unable to parse the
expression: Lexical error at line 1, column 14.
Encountered: "(" (40), after : ""

I notice you user
uri=http://java.sun.com/jstl/ea/core. I don't know if
that is the problem. What is ea/core? Where do I get
it?
Thanks!
