Customizing the email subject for RegistryEvents in WSO2 Carbon

Recently I used org.wso2.carbon.registry.common.eventing.RegistryEvent in WSO2 G-Reg 4.1.0 (based on Carbon 3.2.2) to generate custom email notifications based on different events. Though it was possible to customize the email body, it was not possible to customize the email subject due to a missing feature. In the upcoming Carbon releases this feature will be available and you can set the subject as a parameter with the key "MailConstants.MAIL_HEADER_SUBJECT" for the event as follows.

Versailles

Last-night I watched this comedy, "Midnight in Paris" and there were some nice scenes which were shot around Versailles where I went with few of my friends. Here are some of the pics from my visit.
Once Versailles was the capital of France over a century and still it's renowned for the Palace of Versailles.

On the way to the Palace...

Engineering to take over the world

The most interesting presentation from WSO2Con 2011 :). This presentation done by Samisa, is about how WSO2’s approach to engineering and its secret ingredients to the company’s success. You can hear some inspirational thoughts here and there like “We don’t call people, resources. People are people”. Hope you’ll find it interesting as well.

The Last Supper - Santa Maria delle Grazie

The Last Supper

The Last Supper is one of the most famous paintings by Leonardo da Vinci. He painted the Last Supper at the rear of a dining hall at Santa Maria delle Grazie in Italy.
If you're gonna visit it, make sure to reserve a ticket far ahead as quite a few people are allowed to visit the church, a day.

 

 

Business Process Hosting in the Cloud

I wrote an OT article named "Business Process Hosting in the Cloud". This article discusses multi-tenancy aspect in a cloud computing environment and some of the concerns of hosting business processes in the cloud. WSO2 Business Process as a Service supports development and easy deployment of business processes modeled using the WS-BPEL standard in a multi-tenanted environment. Also it provides functionality for business process management and hosting in the cloud.

Introduction and Advanced Concepts of BPEL

Waruna and I held a tutorial session for WSO2Con-2011 post conference tutorials. We basically explained and demonstrated on what the WS-BPEL constructs are and how to write a simple WS-BPEL process. And also we discussed some advanced concepts related to WS-BPEL as well. Here I have attached the slide-deck we presented.

WSO2Con-2011 Day 03

For the last day of the conference, keynote speakers for the morning sessions were Gregor Hohpe from Google Inc. and Narendra Nathmal from Cognizant Technologies. Gregor Hohpe discussed about his experience on enterprise integration patterns and its past, present and future. Narendra Nathmal talked on "SOA & Beyond: Using Open Source Technologies".
During the last day of the conference, several speakers told their stories on their work related to WSO2.
It was amazed to see how people use open source software and build new stuff and contribute back to the community back. One of my favorite project was "Advanced Business Process Instance Monitoring in WSO2 Carbon" by David Schumm who is a research assistant from Institute of Architecture of Application Systems (IAAS), Germany.
