First, you need an event on request-map (controller) that match your
sent uri
After you define a java service.
If you know service and controller and if the engine of your service is
java you can use this :
*****
GenericValue myObject = delegator.findByPrimaryKey("MyObject",
UtilMisc.toMap("id", id));
if (UtilValidate.isNotEmpty(myObject)) return ServiceUtil.returnError(
"id already exist");
myObject = delegator.makeValidValue("MyObject", context);
myObject.create();
******
It's the greate line ;)
