First, as a suggestion, you will need to understand XML and DTD's: This
will explain what the web.xml file can and can not do.
Then: There are multiple ways of doing servlet mappings: I tend to stay
away from war files, for no particular reason at all, so, in that case,
I need to map all my servlets and their requests in the web.xml file. I
have no experience with war files, but understand you do / can do it
differently using that.
web.xml
You need to publish every and all servlets, FIRST.
You need to map all the servlets to their requests, after publishing all
the servlets ...
<web-app>
<!-- Publish the servlet to the container -->
<servlet>
<servlet-name>Servlet1</servlet-name>
<servlet-class>JavaPackage.ServletClass</servlet-class>
</servlet>
<servlet>
<servlet-name>Servlet2</servlet-name>
<servlet-class>JavaPackage.ServletClass</servlet-class>
</servlet>
<servlet>
<servlet-name>Servlet3</servlet-name>
<servlet-class>JavaPackage.ServletClass</servlet-class>
</servlet>
<!-- Map requests to servlet -->
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/Servlet1/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet2</servlet-name>
<url-pattern>/Servlet2/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet3</servlet-name>
<url-pattern>/Servlet3/*</url-pattern>
</servlet-mapping>
</web-app>
etc, ad infinitum ...
