I was reading my posts from 2007 (Wow, 5 years ago, a lot has changed) about Agile programming and Ruby on Rails (RoR).  Although I used RoR on only 1 project, it seemed a great thing because at that time things such as Spring Roo did not exist. Now with a simple Roo script, followed by some Java code touch-ups one can achieve the same kind of flexibilities that RoR provides using an industry proven language on an set of industry proven platforms (WebSphere, Weblogic, Tomcat, JBoss, etc....) with little risk and reusing our existing farm of coders/developers.  Wow, long live Java. Is there a real need for RoR, I don't think so.  Except perhaps for legacy reason!  HA HA HA! Please contradict me with your comments.  Just keep it civil. When I have time, I shall write an entry illustrating the above Spring Roo example. In the meantime you can look at the example roo scripts in the Spring Roo distribution.

Introduction Multipart mime encoded is a format used to transmit binary and arbitrary data in 1 single HTTP request transaction. In this post, I will describe how to create and process multipart form data using Spring 3.1, the leading industry standard java application framework for creating Java web application.  I will start the discussion from the user perspective by talking about two main use cases and will expand it by describing how these two use cases translate into 7 possible application system use cases. Use Cases Here are some use cases of this feature: A browser submits or uploads a file to a web server using an HTML page. This is by far the most common use case of the multipart form data feature. A multipart is required because the form data and the file are both included in the request body. A java program (a java application or servlet instance) sends multipart form data to a web server (most likely a web service).  This...

What is a workflow? Basically, it is a series of steps to follow in order to achieve a given result. My digital photography workflow is what I recommend any digital photographer (novice or expert) follow to go from taking the shots all the way to having them in your photo library. Why come up with instructions like that? With digital photography if you do not follow a well thought out recipe you find yourself soon (very soon indeed) with a humongous mess due to the number of shots one can take using this technology. Shots are absolutely free, are they not? This workflow assumes that you have a good digital camera capable of shooting in raw mode (or see wikipedia on this topic ). It also assumes that you have Photoshop to do the post processing. That's it. No hidden clause, no long list. Just those two requirements and the will to learn and use this workflow religiously for all of your digital photography experience. Well, I assume you have Photoshop CS4 but this should most...

Just a quick note to tell people that I/we have been running a blog/group site on performance visualization which you can see by clicking here . If you are not already a member you should see a link on the right side that says "Apply for group membership". Just click on this and you could become a happy member.

Hi, just a note to tell you that I will be presenting the paper "Seeing it all at once with Barry" in Toronto on April 16. This is the visualization paper which Neil and I wrote and presented at CMG in San Diego. I look forward to redoing it with some new visuals and hopefully will report back in a timely manner. Till later.

What happened in San Diego. Well, a lot apart from the fact that I was fortunate enough to have two distinguished speakers speak for the network track, namely Peter Sevcik from Netforecast, a world renowned consultant that knows his stuff and whose opinions are often against the current but proven to be correct after. His pet peeve these days is the application performance index or APDEX (see Apdex Alliance ). My good friend Neil Gunther ( Neil's blog ) and I presented a new visualization for the Apdex index which we believe has a lot of potential. The other distinguished speaker is Raj Jain , a well known academic whose performance book The Art of Computer Systems Performance Analysis: Techniques for Experimental Design, Measurement, Simulation, and Modeling (Hardcover) has been the bible for many old timer performance analyst. Raj current interest is in participating in the design of the Internet 3.0 (I don't know where I was but I don't recall Internet 2.0 but heck,...
