Servlet Mapping

                               SERVLET MAPPING

    You can reach to your servlet class from url with the mapping information. If you give url mapping to your named servlet in web.xml file and if this named servlet is related with the real path in web.xml then you can write custom url to the browser and you can reach also you can type it in your program as variable.

    For example you opened a servlet in com.example as exampleServlet and you want to make it associated with the http:/...:../ProjectName/{MyCustomServletName}

You should open your web.xml and

<servlet>

       <description>

       </description>

       <display-name>exampleServlet</display-name>

       <servlet-name>exampleServlet</servlet-name>

       <servlet-class>com.example.exampleServlet</servlet-class>

  </servlet>

    This will introduce your servlet to the web application.

<servlet-mapping>

       <servlet-name>exampleServlet</servlet-name>

       <url-pattern>/exampleServletNow</url-pattern>

</servlet-mapping>

    This maps your url pattern with the servlet name defined as index in web.xml and this index goes into <servlet> tags and searches the same of it. When the search results successfully it returns the servlet-class that gives you the exact builded class to your browser.If your project name is DynamicWebExample

Then you can type as http:/localhost:8080/DynamicWebExample/exampleServletNow or whatever you wrote for mapping information.
