Empty request body in REST service

I have a REST service that accepts JSON in the request body. The method is defined as follows:



In the body of the request is a list of JSON objects representing ShoppingListItem objects, and this works fine. However, I would expect it also to work if the request body is empty--that the items variable would simply be null. However I get a 500 error before it even reaches my service when I post a request with an empty body.

Is this behavior normal/expected?

Thanks!
Sam

I guess you are using Jersey, and in that case Jersey won't be able to find the matching method to call.
As far as I know, this is expected but I would wait for some experts to shed some more lights here.

My answer was wrong and I guess I didn't read your post well.
I was thinking about the uri and not the POST message being blank.

As per the REST architecture, you will call POST only if you want to UPDATE the resource.
And in your case you are calling POST without any payload.
This is an interesting thing. Let me try this.
