RESTful is Rastafarian thinking!

I am back from The Server Side Java Symposium (TSSJS) that occurred in Prague. I was invited to speak about JMX, Monitoring, Management and Troubleshooting in the JDK 6 platform. I spoke 1 hour and enjoyed the conference (only 2 days, I had to leave Prague before the end of the conference).

Some people went to me at the end of my talk with questions related to the ability to persist information that Visual VM or JConsole tools are exposing. My next post will cover this topic in details and should come with a Conf Dumper helping you achieve this use case.

TSSJS is a fantastic conference (it was the first time that I participated). Really it is. It is full of excellent talks from free and open minded speakers. It has been a delight to attend (more particularly) Ted Neward and John Davis talks.

I had already planed to leave Prague not before the promising Ted's REST and SOAP: Arch Enemies or BFF? presentation. And I have been well advised to do so...

Ted has simply presented us the Genesis of the Web Services... From the first second to the last one, it has been a flow full of excellent comparisons, well chosen anecdotes, funny paradoxes, well targeted criticisms, technical excellence, hope, joy, anger,...

The paroxysm has been reached when he has compared Restful with the way Rastafarians see human/business relationships. He described such relations as "cool point to point ones, no intermediary (notion that doesn't exist for Rastafari), nothing expected back, simply giving... exactly like an HTTP URL..." I can't re-transcript the demonstration but it was so true...

When he ended his talk by "Questions?", it has been, for me, like your grand father, seated nearby the fire camp, ending counting you his famous frightening story...

Ted had transformed a technical debates onto a Computing Tale...

Furthermore, I fully adhere with his analysis. He summarized the novelty of the REST approach by "the ability to identify values of your software thanks to URL". This is exactly what I have tried to describe in the 2 parts of the RESTful Access to JMX Instrumentation discussions (and more precisely by the notion of Well Known URL).

So to conclude, if one day you have the chance to go to the TSSJS, please do so, you will be not disappointed.

Really not.
