Correct way for parsing JSON objects containing arrays in Java Servlets (with Gson for example)

Question

I know this is a topic much talked about, but I still wasn\'t able to find a correct and clear answer to my specific problem.

I\'ve got a JSON that looks like this:<

Answer 1

You aren't use JSON to send data to the server:

data : myData,

This specifies parameters as a JavaScript object, but not necessarily as JSON. What this means is that if you do a GET request with:

data: {name1: "value1", name2: "value2"}

The request will be:

http://some/page?name1=value1&name2=value2

This is basically what you're seeing with your first calls, where everything is being converted to a string, then sent as a form parameter.

What you're doing in the second version is almost what you're supposed to do. The only difference is that you need to use a JavaScript object as the parameter to data, not just a string:

data: {arbitraryNameHere: JSON.stringify(myData)}

This will post your "myData" object as JSON, in the parameter named "arbitraryNameHere".
