[java] JSON Structure for List of Objects

I would like to know, whats the right structure for a list of objects in JSON.

We are using JAXB to convert the POJO's to JSON.

Here is the choices, Please direct me what is right.

foos: [
             foo:{..},
             foo:{..}
      ]

or

   foos : [
           {...},
           {...}
          ]

If the first structure is right, what is the JAXB annotation I should use to get the structure right.

As others mentioned, Justin's answer was close, but not quite right. I tested this using Visual Studio's "Paste JSON as C# Classes"

{
    "foos" : [
        {
            "prop1":"value1",
            "prop2":"value2"
        },
        {
            "prop1":"value3", 
            "prop2":"value4"
        }
    ]
}

The second is almost correct:

{
    "foos" : [{
        "prop1":"value1",
        "prop2":"value2"
    }, {
        "prop1":"value3", 
        "prop2":"value4"
    }]
}
