Remove user from request.getRemoteUser (SSO User)

Hi All,

Recently i had a requirement to remove SSO user from request.getRemoteUser(). I tried several ways like nulled the SSO_USER_CACHE session variable, but that all did now work.

I find a work around for this problem like using oracle logout link, but the problem here was that after logout is done, it did not return to my application's login page.

So, i finally found a solution for this :

//remove any session variables you have
String l_return_url = request.getContextPath()+"/jsp/login.jsp";
   response.setHeader( "Osso-Return-Url", l_return_url);
   response.sendError( 470, "Oracle SSO" );

Please comment if you found this useful.

Cloud Computing Definition

While working on a cloud computing research topic, came across The NIST Definition of Cloud Computing and I found it quite comprehensive and found it worth sharing:

“Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”

The definition paper also outlines what the cloud model is:

“This cloud model is composed of five essential characteristics, three service models, and four deployment models.”

As states in the paper, the essential characteristics refer to:

1) On-demand self-service
2) Broad network access
3) Resource pooling
4) Rapid elasticity
5) Measured service

Three service models are:

1) Software as a service (SaaS)
2) Platform as a service (Paas)
3) Infrastructure as a service (IaaS)

Four Deployment Models are:

1) Private cloud
2) Community cloud
3) Public cloud
4) Hybrid cloud

In a nutshell, it provides a excellent overview of the cloud computing and its model.

Simple Jquery Back to Top


Today i am going to show you how to make simple jquery back to top navigation.

First of all import jquery :

<script language="javascript" src="<%=request.getContextPath()%>/script/jquery-1.4.3.min.js"></script>

Then, declare some css

 <style type="text/css">

#toTop {
        border:1px solid #ccc;
        position:fixed; /* this is the magic */
        bottom:10px; /* together with this to put the div at the bottom*/

Then, define div tag for back to top

<div id="toTop">^ Back to Top</div>

Then, some jquery

$(function() {
 $(window).scroll(function() {
  if($(this).scrollTop() != 0) {
  } else {
 $('#toTop').click(function() {

Jxl Performace Tweak

I recently had to generate an excel report with large data set, but it kept failing as it goes out of memory, so i implemented below tweak in order to get output in a proper manner.

WorkbookSettings wbSetting = new WorkbookSettings();  
wbSetting.setArrayGrowSize(5*(int) Math . pow ( 1024 , 2 ));   
WritableWorkbook workbook = Workbook.createWorkbook(response .getOutputStream(), wbSetting);
