    Weblogic to JBOSS/Wildfly AS migration JSP tag-lib directives case sensitive issues

    Viswanath Somanchi Newbie

      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

      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?
