dojo.require(dojo.rpc.*);

//create service object(proxy) using SMD (generated by the json result)
var service = new dojo.rpc.JsonService(${smdUrl});

//function called when remote method returns
var callback = function(bean) {
alert(Price for  + bean.name +  is  + bean.price);
};

//parameter
var bean = {name: Mocca};

//execute remote method
var defered = service.doSomething(bean, 5);

//attach callback to defered object
defered.addCallback(callback);

This problem comes up from time to time and I always forget what it
was, search the list and you find a few threads about it. It isn't
related to the json plugin itself (you will get the error on the first
used tag)
