How to configure Servlet on Tomcat Server and fix javax.naming.NameNotFoundException?

Recently I deployed an app to Tomcat Server. It's not working because the app can't find the Servlet. I thought the servlet-class in web.xml was okay but apparently the syntax/mapping is wrong since they cant find it...

web.xml

<servlet>
        <servlet-name>ControllerServlet</servlet-name>
        <servlet-class>controller.ControllerServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

catalina.log

Solution

  • It's not working because the app can't find the Servlet.

    Wrong.

    javax.naming.NameNotFoundException: Name [controller.ControllerServlet/categoryFacade] is not bound in this Context. Unable to find [controller.ControllerServlet].

    It can't find the name controller.ControllerServlet in the naming resources Somewhere you are using java:comp/.../controller.ControllerServlet/categoryFacade.

    I suggest you look into where you are using categoryFacade for a start.
