Weblogic to JBOSS/Wildfly AS migration JSP tag-lib directives case sensitive issues
I have been facing JSP tag-lib directives case sensitivity issue while migration application from Weblogic to JBOSS. I see that below JSP code works in weblogic and throws exception is JBOSS.
Index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
<head>
<title>Count to 10 Example(using JSTL)</title>
</head>
<body>
<c:forEach var="i" begin="1" end="10" step="1">
<c:out value="${i} " />
<br />
</c:forEach>
<c:choose>
<c:when Test="${true}">
<p><b>Setting: </b></p>
Yes
</c:when>
<c:otherwise>
<p><b>Setting: </b></p>No</c:otherwise>
</c:choose>
</body>
</html>
In Weblogic output is as below
1

Setting:
Yes
In Jboss
Servlet Path:/index.jsp

I know issue is we should use test instead of Test inside c:when directive. I wanted to know why the same code is working in weblogic and not in Jboss?
I know tag lib is case sensitive in that case I wanted to understand why there is difference in behavior between weblogic and Jboss?
