Looks like there are two problems. One is servlet mapping issue another is database connectivity issue. Please confirm.

Check servlet mapping in web.xml is appropriate. Paste mapping content and absolute path of the servlet here.

Alsoif there is database issue describe what kind of database issue it is.

Step 1: Make sure you have ControllerServlet.class file available in WEB-INF/classes folder?



Step 2: Add below to your web.xml file at the end of the web.xml before <web-app>

            <url-pattern>/ControllerServlet</url-pattern>
</servlet-mapping>

Step 3: Access your servlet with below url
