Question

I want to retrieve the request scope attribute in javascript as follows. How can I achieve this?

function caseChanges(req) {
    var innervalue= "${dashboardTicketSummary}"
    alert("nand you are 1234");
    alert(innervalue);
}

Assumin the javascript is included inline on the jsp page — you’re on the right track, you just need to make sure the attribute is set (typically by your controller class) on the HttpServletRequest object, ie:

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse res)
{
  DashboardTicketSummary dts = ...; // code to obtain ticket summary here

  req.setAttribute("dashboardTicketSummary", dts);

  // code to dispatch to your jsp page here
}

Of course there are many other more sophisticated way — especially is you use popular MVC framework such as Spring
