Hi every one,
I am unable to get the output of "result.jsp"
---result.jsp---
<%@ page import="java.util.*" %>
<html>
<body>
<h1 align = "center"> Beer Recommendations
JSP</h1>
<p>
<%
List styles = (List)request.getAttribute("styles");
Iterator it = styles.iterator();
while(it.hasNext()) {
out.print("<br>try: " + it.next());
}
%>
</body>
</html>
I am getting java.lang.NullPointerException error in "http://localhost:8080/Beer-v1/result.jsp"
My BeerExpert.java & BeerSelect.java is compiled successfully without error or warning
