to implement this servlet just follow these steps:

  • In Eclipse, right click over your web project and select New->Servlet


  • From the “Create Servlet” window, mark the “Use an existing Servlet class or JSP” checkbox, then use the browse button to select the WebClientMultiSessionServlet servlet and click on the “Finish” button.




  • Open your file and change the value for the Define.WSACTION entry to the following value “WSACTION=/<YOUR WEB PROJECT>/ WebClientMultiSessionServlet”, example:
    • Original
  •          Define.WSACTION=/TestWeb/WebClientServlet
