What I have tried is 

First.jsp
   <form name = "button" style="VISIBILITY: visible">
                    <table cellspacing=5 cellpadding=5 bgcolor="lightblue" colspan=2 rowspan=2 align="center">
     <TR> <TD> <INPUT TYPE="button" onclick="sub1();hide();" VALUE="DOWNLOAD"></TD>
    <script>
     function popup()
                    {
                        popupWindow = window.open('delete','name','width=300,height=100');
                        popupWindow.focus();
                        window.close();     
                    }

delete.jsp

<%
String Pdfpath=   session.getAttribute("pdfpath").toString();
 File f =new File(Pdfpath);

 Boolean flag=false;
  if(f.exists())
  {
    flag=f.delete();
  }
  else 
  {
    out.println("File not found to delete");
  }

%>
<html>
<head>
<title>Delete file in java</title>
</head>

<body>
<%
 if(flag==true)
 {
  out.println("File Has Bean deleted successfully");
 }
 else
 {
  out.println("Error: Unable To Delete The File");
 }
%>
</body>
</html>

From my first jsp I'm passing some path to another delete.jsp on the button click.That jsp delete the file on my directory and giving an message.I want that message to es of in a message box at the same time that window should not e.

I don't like add all deletion code in javascript function so that I'm going for another jsp. Is it possible to hide the window and show only the confirm message box in delete.jsp page.I need some help.

Thanks

You can use the following code as delete.jsp ;)

<%
    String Pdfpath = session.getAttribute("pdfpath").toString();
    File f = new File(Pdfpath);

    Boolean flag = false;
    if (f.exists()) {
        flag = f.delete();
    } else {
        out.println("File not found to delete");
    }
%>
<html>
    <head>
        <title>Delete file in java</title>
    </head>

    <body>
        <%
            String message = "";
            if (flag == true) {
                message = "File Has Bean deleted successfully";
            } else {
                message = "Error: Unable To Delete The File";
            }
        %>
        <script type="text/javascript">
            alert('<%=message%>');
        </script>
    </body>
</html>
