Greetings Ranchers!

I�ve run through some confusion in Overriding jspInit() method. I am using the Head First book. I�ve followed the instruction in the book in configuring the servlet init parameter then inserted the <jsp-file> element in th DD.

<servlet>
<servlet-name>MyTestInit</servlet-name>
<jsp-file>/TestInit.jsp</jsp-file>
<init-param>
<param-name>email</param-name>
<param-value>djabonete@gmail.com</param-value>
</init-param>
</servlet>

Then my jsp:

<%!
public void jspInit() {

ServletConfig sConfig = getServletConfig();
java.util.Enumeration e = sConfig.getInitParameterNames();
while(e.hasMoreElements()) {
System.out.println("sConfig = " + e.nextElement().toString());
}
String emailAddr = sConfig.getInitParameter("email");

ServletContext ctx = getServletContext();
ctx.log("emailAddr = " + emailAddr);
ctx.setAttribute("mail", emailAddr);

System.out.println("jspInit has been Initialized");
System.out.println("ctx.getAttribute(\"mail\") = " + ctx.getAttribute("mail"));
}
%>
<html>
<head>
<title>JSP Init Test Page</title>
</head>
<body>
<%= getServletContext().getAttribute("mail") %>
</body>
</html>

I did get the �mail� attribute sets in the Context. I would really appreciate your help. Thank you very much!

Please dont post the same question in more than one forum. Let's continue the discussion in your other post.
 
It is sorta covered in the JavaRanch Style Guide.
