My First Tomcat Servlet

Question

I seem to be having trouble with Tomcat servlets and even setting up my own. I am using Windows Vista x64 bit. I CAN connect and see the servlet examples. I just don't know how to go about creating my own.

Can anyone pinpoint to me a guide on "my first servlet" with a step-by-step instructions on how-to?

Thanks.

Anyone?

Answer 1

1. Create the servlet class:

   package com.example;
   import javax.servlet.http.HttpServlet;
   public MyServlet extends HttpServlet {}
   

2. Override the doGet(..) method in your class:

   public void doGet(HttpServletRequest request, HttpServletResponse response) {
        response.getWriter().print("Hello world");
   }
   

3. Put your servlet class in WEB-INF/classes/com/example/MyServlet.class

4. Go to (or create) your web.xml (like this) in the WEB-INF/ folder

5. Map your servlet in web.xml:

   <servlet>
       <servlet-name>myServletName</servlet-name>
       <servlet-class>com.example.MyServlet</servlet-class>
   </servlet>
   
   
   <servlet-mapping>
      <servlet-name>myServletName</servlet-name>
      <url-pattern>/myServlet</url-pattern>
   </servlet-mapping>
   

6. Access your servlet using http://localhost:8080/myApplication/myServlet

The Development Processes section of the Tomcat 6.0 Application Developers Guide is a step by step guide that covers creating your sandbox, adding content, building a WAR file and deploying it. Another section gives you a pre-built WAR file that you can use an example to help you get started.

If you area beginner to Java Web developement, you might consider using some IDE that can support your development process, deploy and debug your application and support additional frameworks you might use in the feature (JSF, Spring MVC, Dojo etc.)

Deploying with these is a single click. It is really hard to find a reason not using an IDE here.
