Hi,
I was working on the scenarios for the JSON-RPC mentioned on the SCA
Java Web 2.0 Road map. I tried the first scenario i.e. 'Empty catalog
throws a Business Exception. Business Exception should properly
propagate and display nicely to client'
I tried simulating the exception condition by making the .get() method
of the FruitsCatalogImpl.java throw the business exception.
First I noticed that the JSON representation of the exception is not
being recognized by the browser js engine.
Currently, the Tuscany runtime is producing something like :
"{\"id\":3,\"error\":services.ClientException: Fruits Catalog empty}"
Instead, I think it should be :
"{\"id\":3,\"error\":{\"trace\":\"services.ClientException: Fruits
Catalog empty\",\"code\":490,\"msg\":\"Fruits catalog empty\"}}"
Is it some issue related with the binding where the actual JSON error
message is formatted ?
After fixing this issue, I was still having issues with the exception
not being caught by the try/catch block, and I had to modify the
store.html client code as follow :
function init() {
var item = new Array();
try
{
item = catalog.get();
}
catch(e)
{
alert(e.message);
return;
}
catalog_getResponse(item);
shoppingCart.get("", shoppingCart_getResponse);
}
Thanks,
Dhaval
