title: Tomcat servlet problem - class not found
body: <p>I'm trying to learn how to develop a servlet to run under Apache's Tomcat server on Windows XP. I'm using Tomcat 6.0 with Java SDK 1.6.0_17. My webapp is a simple Hello, world type which I'm building using the latest version of the Eclipse IDE. I'm able to run all the examples in the Tomcat installation but when I export my app from Eclipse to the Tomcat webapps folder and try to access it from my browser, I get errors pointing to the fact that the <code>javax.servlet.http.Servlet</code> class couldn't be found. I searched the SDK tree and couldn't find any thing with <code>javax</code> in the name so I'm guessing it isn't there.</p>
  
  <p>I've googled around but haven't found anything with this exact, same issue. Any suggestions what I can try?</p>
