JSTL giving Error when trying to access bean
Question
I have been at this for over a week. I am getting an error when I try to access my bean. My error reads:
The value for the useBean class attribute beans.Bean is invalid.
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:41)
Here is the the code:
package beans;
public class Bean {
private String message = "This is from the bean";
public Bean(){
}
public String getMessage(){
return message;
}
}
<%@ page language="java" contentType="text/html; charset=US-ASCII"
pageEncoding="US-ASCII"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page import = "beans.Bean" %>

<div id="intro">
<table border="1">

<th>2</th>

<tr>

<td>Two</td>

</tr>
</table>
</div>
<jsp:useBean id="message" class="beans.Bean" scope="session" />
<p>From the bean: <c:out value="${message.getMessage()}" /></p>
</body>
</html>
I am using Tomcat 8 and my JDK is 8 as well. I have added the jstl.jar file to my class path, the tomcat lib folder and to the WEB-INF lib folder. I also deleted Tomcat 7 because I read there might be conflicts with two Tomcat versions downloaded.
Please, any advice would be greatly appreciated.

I have found a solution to my own probelm:
There was a conflict with my JSTL.jar files. I had two different ones in my J2EE library folder and this whole time I kept looking into the JDK folder.

尝试使用message.message而不是message.getMessage（）
