I used to do Grails applications where controllers return some model to the view. Now, I have to create the REST web service, which will accept and return the data in JSON or XML format. I want to map it to some URL resource as well.
Please give me some bits of advice (plugins, the code snippets)
Thanks in advance
Read up on the grails restful api plugin
http://grails.org/plugin/restful-api
It is very thorough and well documented
Or, if you just want a simple REST api, you can use the built in method for return json from your controller.
