I was trying an example of java servlet book. In the example, the prog. (see
excerpt below) should read the parameter values from web.xml and use the
values accordingly. However, it seems it is unable to read the values & thus
only able to give me default values the prog. use.
I can't find what's wrong.
advice pls.

The ShowMessage classes is part of the mypackage package under the mypackage
folder. Below is the excerpt: -
public void init(ServletConfig config)
throws ServletException {
super.init(config);
message = config.getInitParameter("message");
if (message == null) {
message = defaultMessage;
}
try {
String repeatString =
config.getInitParameter("repeats");
repeats = Integer.parseInt(repeatString);
} catch(NumberFormatException nfe) {
}
}
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String title = "The ShowMessage Servlet";
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String title = "The ShowMessage Servlet";
out.println(ServletUtilities.headWithTitle(title)
"<BODY BGCOLOR = \"#FDF5E6\">\n" +
"<H1 ALIGN=CENTER>" + title + "</H1>");
for (int i = 0; i<repeats; i++) {
out.println(message + "<BR>");
}
out.println("</BODY></HTML>");
}
I've edited the web.xml file in the webapps\examples\web-inf directory and
include the followings: -
<servlet>
<servlet-name>
ShowMsg
</servlet-name>
<servlet-class>
mypackage.ShowMessage
</servlet-class>
<init-param>
<param-name>message</param-name>
<param-value>Sembawang</param-value>
</init-param>
<init-param>
<param-name>repeats</param-name>
<param-value>5</param-value>
</init-param>
</servlet>
