The function rpcFunction() is the async part.
I'm using dojo , so the function looks like :
function rpcFunction() {
var kw = {
url: "${urlFromClass}",
load: function(type, data, evt) {
// do what you want with "data" retrieved from server
side
},
method: "GET",
mimetype:"text/json"
};
dojo.io.bind(kw);
}

Also, what do you do with yourUrl once you have it? In addition, the
JSONRpcClient constructor expects to be talking to a servlet. T5 is a
ServletFilter.
