[jboss-user] [Beginners Corner] - Http 500 Internal Server Error

Sun Apr 22 22:22:45 EDT 2007

Could anyone provides me some solution?

I encountered "HTTP 500 internal server error" while testing a jsp that forwards to an error page whenever user inputs a wrong data type on a web form to sum 2 inputted numbers.    The application server version I am using is JBoss 4.0.5.GA application server.  

My Calculate3_html.jsp file is:
<HTML>
  | <HEAD><TITLE>Calculator</TITLE></HEAD>
  | <BODY>
  | 
  | <%@ include file="Calculate3Header.html" %>
  | <P>Enter 2 nos. and click the Calculate button.
  | <p>
  | <FORM METHOD=GET ACTION=Calculate3.jsp>
  | <INPUT TYPE=TEXT NAME=Value1><BR>
  | <INPUT TYPE=TEXT NAME=Value2><BR>
  | <INPUT TYPE=SUBMIT VALUE=Calculate>
  | </FORM>
  | </BODY></HTML> 

My Calculate3.jsp file is:
<%@ page language="java"  pageEncoding="UTF-8" errorPage="Calculate3Error.jsp" %>
  | 
  | <%! 
  | 	// No try/catch for NumberFormatException
  | 	private double toDouble(String value) {
  | 		return Double.parseDouble(value);
  |     }
  | %>
  | 
  | <%
  | 	double value1 = toDouble(request.getParameter("Value1"));
  | 	double value2 = toDouble(request.getParameter("Value2"));
  | 	double sum = value1 + value2;
  | %>
  | 
  | <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
  | <html>
  |   <head>
  |   </head>
  |   
  |   <body>
  |   
  | 	<%@ include file="Calculate3Header.html" %>
  | 	
  | 		
  |     The sum of <%= value1 %> and <%= value2 %> is <%= sum %>
  |   </body>
  | </html>

My Calculate3Header.html file is:
<H1><I>A Simple Calculator (Exercise 3)</I></H1>

My Calculate3Error.jsp file is:

<%@ page language="java"  pageEncoding="UTF-8" isErrorPage="true" %>
  | 
  | <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
  | <html>
  |   <head>
  |   </head>
  |   
  |   <body>
  |     
  |     <%@ include file="Calculate3Header.html" %>
  |     
  |    
  |     
  |     Calculate3Error.jsp reported the following error:
  |     <I><%= exception %></I>
  |     <br>
  |     <a href="Calculate3_html.jsp">Click here to try again</a>
  |   </body>
  | </html>

Thank you.
