MBO development for RESTFUL Webservices

Hi all,

  I am new to MBO development in SUP platform. I have some restful Webservices for reading, updating and deleting certain records. The restful webservice urls are

http://app2342.appspot.com/rest/insertservice/insert   [parameters are cuskey,cusname and method is POST]

http://app2342.appspot.com/rest/insertservice/update  [parameters are cuskey,cusname and method is POST]

http://app2342.appspot.com/rest/insertservice/delete  [parameters are cuskey and method is POST]

http://app2342.appspot.com/rest/hello/test  [for reading the records]

I want to know how to provide the input parameters for insert update and delete. Do I need to provide XSD files for request as well as response. Is there any tutorial available for MBO creation for Restful webservices. I could do the read successfully. If some one explains the steps for configuring this MBO, it will clear my fundamentals.

thanks and regards,
