Accessing ServletContext attribute from Action Class.

[wai chun chor]

Hi, I have a Struts 2 application where a servlet runs on startup, it saves my datasource config into a servletContext:

ServletContext sc = event.getServletContext();
sc.setAttribute("dbPool", connectionPool);

The problem is I could not get this value from my action class where i need this datasource connection.

Any help is appreciated.

hi

try this in your action

ServletContext servletContext = ServletActionContext.getServletContext();
servletContext.getAttribute("dbPool");

It's not better approach set as dataSource in webserver.

Struts Action objects are part of a Struts-based Controller. Ideally, you should not want to connect or access a data source from the Controller, i.e. Action objects.

As a treat, below is how to get the ServletContext object

    public ActionForward execute(ActionMapping mapping,
                                            ActionForm form,
                                            HttpServletRequest request,
                                            HttpServletResponse response) throws Exception {
    
        HttpSession session = request.getSession();         
        ServletContext ctx = (ServletContext) session.getServletContext();
         ...
   }
