I have written, for practice, a simple webpage that will display to the user a drop down menu. The user will select a number and hit the Submit button.

After that, the servlet will be executed and will send back a list of even numbers.

enter image description here

Looking at the address in the address bar of the web browser, it is:

http://localhost:8080/FindEvenOdd/FindEvenOdd

I want it to be http://localhost:8080/FindEvenOdd/Result

How do I do that ?
My DD looks like this: 

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
    web-app_2_4.xsd"
    version="2.4">

    <servlet>
        <servlet-name>Evens</servlet-name>
        <servlet-class>FindIt</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>Evens</servlet-name>
        <url-pattern>/FindEvenOdd</url-pattern>
    </servlet-mapping>
</web-app>

my HTML: 

<html>
    <head>
        <title> List of Even/Odd Numbers </title>
    </head>

    <body>
        <form method="POST" action="FindEvenOdd">
        <center>
            <select name="number" size="1">
                <option> <50
                <option> <100
                <option> <150
            </select>
        </center>
            <center>
                <input type="SUBMIT">
            </center>
        </form>
    </body>
</html>

What I tried

  • I changed the action="FindEvenOdd" to action="Result"
  • i changed the <url-pattern> to Result

    • I did the above two things simultaneously but got a 404.
    So,
    What do I do to get http://localhost:8080/FindEvenOdd/Result

      What you tried is almost correct. The url-pattern must be set to /Result.

      Some notes though:

      • always put your classes in a package. Not in the default package
      • generate valid HTML5. center is a tag that shouldn’t be used for a long time, and your select box is invalid HTML.
      • Learn servlet 3.0 rather than servlet 2.4.
