Hi,
When I make any changes to the code, I don't stop/start the
server but do need to close/restart the explorer. The refresh did not
work. And, yes, when I have classes in
c:\jakarta\webapps\root\web-inf\classes, it works.
Now the source
codes...
package test;
import javax.servlet.*;
import
javax.servlet.http.*;
public class ServletUtil
{
public static final
String docType = "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0
Transitional//EN\">\n";
public static String getHeadWithTitle(String
title)
{
return (docType +
"<html>\n<head><title>" + title +
"</title></head>\n");
}
}
package test;
import java.io.*;
import javax.servlet.*;
import
javax.servlet.http.*;
public class HelloWorld extends
HttpServlet
{
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException
{
response.setContentType("text/html");
String
forHTML = ServletUtil.getHeadWithTitle("New Title") +
"<body><h1>Hello World using
methods</h1></body>\n</html>";
PrintWriter out
=
response.getWriter();
out.println(forHTML);
}
}
Thanks, June

package
G'Day
June,
Just
curious...Is the servlet reloadable ? I have used the JSWDK(where servlets are
not reloadable), and when I add a new servlet, or change code, I have to
stop/start the server for the
class to be recognized. I'm sure apache
allows servlet reloading, but I'm wondering if it needs to be
defined.
Since localhost/servlet/HelloWorld works, I assume you have the class also in
c:\jakarta\webapps\root\web-inf\classes
Can you also post the source code
?...
Thanks
Bill

running servlet in package
I am reading Core Servlets and JSP and
trying to run a servlet in a package. I have put "package test; " in the
source code and compiled it in the dos using javac -d
c:\jakarta\webapps\root\web-
inf\classes HelloWorld.java with no
problem. After running that command, I have this class file in the
c:\jakarta\webapps\root\web-inf\classes\test. However, when I
type
"localhost/servlet/test.HelloWorld" in the explorer, I get the
following error.
Internal Servlet
Error:
java.lang.NullPointerException

Please tell me what I am doing
wrong. The Apache server and the tomcat are running just fine, because I
can run this servlet(without the package statement) by typing
localhost/servlet/HelloWorld
with no problem.
Cheers,
June
