Solution

  • you can use servlet for that as below, define into web.xml 

    <servlet>
   <servlet-name>YourServletName</servlet-name>
   <servlet-class>com.abc.xyz.YourServletClassName</servlet-class>
   <load-on-startup>1</load-on-startup>
</servlet>

    in YourServletClassName.java file you can write your code.

    Hope it helps you.
