Here is a blog entry that was sitting in my Drafts folder for a long time (just because I didn't realize :). Anyway, it shows how to install Open Solaris 2008/11 on Virtual Box. The original install was done using Virtual Box 2.0.6. I installed Virtual Box 2.1 this morning and the image was easily recognized by the updated Virtual Box.

Here are the basic steps.


Create a new VM ...



As part of the previous step, create a new Virtual Disk mapping to the downloaded Open Solaris image ...

(This is a purely technical or at least semi-technical post about a database and Web20 architecural issue.)

I just noticed about 5-10 status updates from my friends on Facebook are duplicated. Reading from the top I get to "17 hours ago" and then it restarts with duplicate status update messages from "5 hours ago".

For the last few months, I've been working feverishly to get the web2.0kit open-sourced. What is the web2.0kit, you ask ? We introduced this at our session at the Velocity conference. The web2.0kit is a reference architecture to help anyone running a web application evaluate the suitability, functionality and performance of various web technologies.

Most web2.0 sites today use open source languages and frameworks such as PHP, Ruby on Rails and Java EE to develop their applications. Deployments of these applications also use popular open source servers such as Apache httpd, MySQL, memcached and glassfish. Many other servers/technologies such as lighttpd, nginx, mogileFS, mongrel, thin, JRuby are also gaining popularity. To help understand the differences in …

TOTD #42 explained how to create a simple Java Server Faces application using NetBeans 6.1 and deploy on GlassFish. In the process it explained some basic JSF concepts as well. If you remember, it built an application that allows you to create a database of cities/country of your choice. In that application, any city/country combination can be entered twice and no errors are reported.

This blog entry extends TOTD #42 and show the list of cities, that have already been entered, starting with the letters entered in the text box. And instead of refreshing the entire page, it uses JSF Extensions to make an Ajax call to the endpoint and show the list of cities based upon …

TOTD #9 explained how to configure JDBC connection pooling for Rails application deployed on GlassFish v2. There are several benefits of using using the JDBC connection pools:

• No need to create a new database connection for each Rails instance.
• No need to specify your password in database.yml or create a hack to hide it.
• No garbage collection of connection after each use.

And because of the above mentioned (and other reasons) an improved application performance, scalability and efficiency.
The only way to deploy a Rails application on GlassFish v2 is to create a WAR file using …

This TOTD (Tip Of The Day) shows how to create a simple Java Server Faces application using NetBeans IDE 6.1. This is my first ever Java Server Faces application :) Much more comprehensive applications are already available in NetBeans and GlassFish tutorials.

The application is really simple - it allows you to create a database of cities/country that you like. You enter the city & country name on a page and click on Submit. This stores the data entered in the backend database and displays all the stored values in a new page. This application demonstrates simple JSF concepts:

Hi,

I needed to install AMP on my OpenSolaris laptop to do some PHP development, and I thought some people would be interested to know how to do this.

Here we go.

AMP is available from the OpenSolaris Web Stack project, which also includes other open source components such as Perl, Ruby, Memcached, Lighthttpd, etc.

The nice thing with OpenSolaris is that - assuming my laptop is connected to the Internet - I can use the Package Manager to automatically download and install AMP on my laptop. I access the Package Manager through the menu System/Administration.

Once the Package Manager is launched, I make sure that the Repository is set to opensolaris.org and  I do a search on amp:

The amp and amp-dev packages are now listed in the selection …
