Hi All,
I have a servlet which is invoked from a jsp page. While the serlvet
is executing, the jsp page is waiting for the servlet to complete.
When the servlet completes, it informs the waiting jsp to redirect to
another page. The waiting jsp has implemented onload which will
redirect to the page informed by the servlet
Server : (tomcat 6.0), Browser - IE 6.0, OS - WinXP
When the servlet takes a long time to return, the page is not
redirected. It seems the browser has given up on the request or timed
out . If the servlet comes back quickly, it works fine. The problem is
seen when the servlet takes a long time to finish.
//waiting jsp code
<html>
<head>
<title>Please wait......</title>
</head>
<body style='width: 100%;' onload='dynamicRedirect();'>
<br><br>
<div class='indent'><div id='dynamicDisplay'> </div></div>
<script>dynamicDisplayScript( 0, 'please wait' );</script> <br><br>
<%
out.flush();
//wait for the serlvet to finish
String servlet_url = "/servlet/ComputeServlet";
request.getRequestDispatcher( servlet_url ).include( request,
response );
%>
<SCRIPT language='JAVASCRIPT'>
function dynamicDisplayScript( x, info )
{
var y = 0;
var tab = FindElementById( "dynamicDisplay" ) ;
var display_val = "<h2>"+info;
var display_end = "</h2>";
if( Number( x ) == 0 )
{
tab.innerHTML = display_val+ "." +display_end;
y = 1;
}
else if( Number( x ) == 1 )
{
tab.innerHTML = display_val+ ".." +display_end;
y = 2;
}
else if( Number( x ) == 2 )
{
tab.innerHTML = display_val+ "..." +display_end;
y = 3;
}
else if( Number( x ) == 3 )
{
tab.innerHTML = display_val+ "...." +display_end;
y = 4;
}
else if( Number( x ) == 4 )
{
tab.innerHTML = display_val+ "....." +display_end;
y = 0;
}
var wait = 1000;
window.setTimeout( "dynamicDisplayScript(" + y + ", '" + info
+ "' )", wait );
}
//This is called after the page is loaded when the servet returns
function dynamicRedirect()
{
<%
String url = ( String )request.getAttribute( "RedirectURL");
%>
window.location = url;
}
</SCRIPT>
Appreciate any help
Thanks
