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

i am setting it in an action class , i am having issue pulling the value on a jsp page in java script.

Sorry, My Bad. It was a ajax call.
set value to request attributes and write this piece of code in a script tag on jsp page (like index.jsp):
<script>
function caseChanges(req){
var innervalue= "${dashboardTicketSummary}"
alert("nand you are 1234");
alert(innervalue);
}
</script>
for better maintainability, you can gathering all attributes to a global object on jsp, and refer to it on other js files:
index.jsp
<script>
var REQUEST_ATTRS = {
dashboardTicketSummary : '${dashboardTicketSummary}',
otherAttributes :'${otherAttributes}'
};
</script>
other.js
function caseChanges(req){
var innervalue= REQUEST_ATTRS.dashboardTicketSummary ;
alert("nand you are 1234");
alert(innervalue);
}
