How to show javascript alert with string val in jsp

I am trying to show an alert in my jsp page with the following code.

<%
---------------
---------------
out.write("<script type='text/javascript'>\n");
out.write("alert('Hello')");
out.write("</script>\n");
---------------
---------------
%>

Everything is working fine. Alert is coming when page is loading. Now I want to show an alert with string variable. For this I changed the above code to below. Now the alert is not coming.

<%
---------------
---------------
String name = (String) application.getAttribute("name");
System.out.println("name = "+name);
out.write("<script type='text/javascript'>\n");
out.write("alert('Hello'+name)");
out.write("</script>\n");
---------------
---------------
%>

Could you please tell me how to add string variable to the above alert function.

You can try this with EL without jsp scriplets:

<script>
    alert('Hello ${applicationScope.name}');
</script>

OR

<script>
    alert('Hello ${name}');
</script>

P.S. Do not use application scope to store user specific values, its shared among the different sessions(users). Try HttpSession or HttpServletRequest instead.

EDIT

<%
   out.write("<script>");
   out.write("alert(\"Hello " + application.getAttribute("name") + "\")");
   out.write("</script>");
%>
