Is something I’ve been working on at wso2 for sometime, if you are following me I have tweeted the updates, releases etc. Jaggery went live with its fifth milestone, few weeks ago at jaggeryjs.org, its still young and has alot to improve.
A very simple page that prints out some request properties in jaggery looks like,
Architecture : In brief, events are generated randomly, ESB will act as an event sink, and it will publish the events to the subscribed parties (to a service deployed in WSO2 AS). There is a gadget deployed in WSO2 Gadget Server where it will poll the received events from the service periodically.
At the ESB end we will have to set up the event sink as following,
Then you need to create a topic in the ESB and subscribe the created service. Steps in doing so is documented here
A very simple service to accumulate the events (this is not at all production grade, who whats to keep all the event in memory ;) )
At WSO2 we are busy with something new for the new year :) and we have just pushed the milestone-1 of it, not so complete but you can sure taste it. Everybody knows that WSO2 is big on Web Services, but over the years we have seen that the barrier between Web Services and Web Applications hasn’t been lowered. “Jaggery” is an effort to diminish this barrier and to merge the development process of services and applications.
Includes support for,
HTTP request/response and session
Server side XMLHttpRequest
Web Service invocation
Open Social gadgets
A hello world server-side script looks as follows,
and a HTML mixed, server page looks like,

WSO2Con 2011 is a technical and IT-Biz conference organized by WSO2 inc, and 2011 is its second consecutive time. Last year the conference concluded grandly and it discussed many technical topics such as enterprise computing, cloud, web services security, enterprise data etc. It concluded with a great panel discussion on the topic “A Walk Down Memory Lane: XML, Web Services & SOA from 1990 to 2010″ and the panelists were some of the renowned personalities in XML Web services space.
So the conference is back this year, and it will be on September 12th to 16th at Waters Edge Colombo, There will be two tutorial sessions (12th and 16th) and the conference will span for three days (13th, 14th and 15th). The agenda was recently announced officially, and it surely looks interesting. I guess if you are into Distributed Computing, SOA and Cloud this would be the right place to and the event to be apart of.
Also am quite proud to blog about that I will also be one of the speakers in the 2011 conference, The topic I submitted was “User interfaces in distributed environments” and later I altered it to “Users: The SOA Last Mile” to make it broader.
Main reason for this topic is that I have done some resent work close to the Users of information systems and about delivering information to users effectively and efficiently, I believe I can talk about it, and maybe give some insight about How important the “Last Mile” is. Anyhow I don’t wona write about What I will be talking, coz mainly its still a blank paper for me too :D
So yeah what I wanted to say is that WSO2Con will be happening on September in Colombo, and I have no doubt that it will be one great tech Conf with a great set of talks and workshops, so hope to see you there soon !!!
