Rest was a really big deal in the Java web-app world for about a year...

It was back when early versions of Struts were 'the designated alternative', and in the bad old days of J2EE and JAX-RPC.

Then Java EE 5 came out, which solved large chunks of the pain that J2EE inflicted, JAX-RPC got replaced with the infinitely better JAX-WS and there was a new breed of web frameworks as well, which blew Struts out of the water.

About that time REST essentially became 'yesterdays technology, solving yesterdays problems'.

I find it interesting that the guy banging the REST drum is a Ruby fan. Has REST always been part of Rails? Or is it something that has crept in over the last couple of years?

Is there anything genuinely new here, or is it the same old story, some dude clinging desperately to an obsolete technology?
