Problem viewing a hello world servlet
I am doing the Introduction to Java Servelet Technology tutorial from the ibm website.
I created a hello world servlet:
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloWorldServlet extends HttpServlet { // HelloWorldServlet is underlined in red, when I mouse over // the error message is: does not declare a final static UID for type long
public void service(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
PrintWriter writer = response.getWriter();
writer.println("Hello, World!");
writer.close();
}
}
I started my tom cat.
I created my XML file that I need to put in my WEB-INF folder:C:\Eclipse\HelloWorld\WEB-INF
--
<!DOCTYPE web-app PUBLIC '-//Sun Microsystems, Inc.//DTD
Web Application 2.3//EN' 'http://java.sun.com/dtd/web-app_2_3.dtd'>
<web-app>
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>HelloWorldServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
</web-app>

When I browse to: http://localhost:8080/HelloWorld/hello
I get this:
HTTP Status 404 - /HelloWorld/hello
-
Not sure if this has anything to do with it:
In my eclipse when is tarted tom cat (I have the plug in ).
This is what I got in the out file:

Also:
What about at this line
public class HelloWorldServlet extends HttpServlet {// Why is HelloWorldServlet underlined.
