"Your First Servlet" example on pg. 64 (Pro JSP, 2nd edition) doesn't work in Tomcat. The servlet cannot be found (404 error). No mention is made of how to modify web.xml, which needs to be changed: the text says only "We will expand on our use of web.xml as it is needed below". but then it doesn't mention it again.

The servlet works fine. Check your web.xml file in %CATALINA_HOME%\webapps\myApplicationName\WEB-INF.

You must include the servlet descriptor:

<servlet>
   <servlet-name>MyServlet</servlet-name>
   <servlet-class>com.MyPackage.MyTest.MyServlet</servlet-class>
</servlet>

and a servlet mapping entry

<servlet-mapping>
    <servlet-name>MyServlet</servlet-name>
    <url-pattern>/MyServlet</url-pattern>
</servlet-mapping>

Then you can call the servlet with the url
http://myhost:myport/myApplicationName/MyServlet

after restarting Tomcat.

When you ask a question in a newsgroup, you should always include which version of software you are using, which platform. Also, check your logfiles for any specific error messages.

Hi.
I have configured WLS8.1 on WnXP-Prof. I am getting the same error like Marvin. I tried adding <servlet-mapping> section also as suggested by infnist, but the error persists.
