                                                "address : \""+webVisitor.getProfessionalAddress()+ "\","+

    },
    success: function(data) {
        $.each(data, function(k, v) {
            console.log(k + " Value " + v);
            $("#city").text(v.city);
            $("#zipcode").text(v.getZipCode);
            $("#Adress").text(v.getProfessionalAddress);
        });
    },
    error: function(data) {
        console.log("error:", data);
    },
    type: "post",
    datatype:"json",
});

Note that the jQuery setting is dataType with a capital T. To do the JSON parsing manually, use the parseJSON function. However, if you set the Content-Type of your servlet response to application/json, the datatype should be auto-detected.

After you fixed this: Does it work? What is the value of the data argument of your success handler?

console.debug(data);

As Neal already said, JSON parsing expects valid JSON strings starting with jQuery 1.4. You can validate your JSON jsonlint.com.

In jQuery 1.4 the JSON data is parsed in a strict manner; any malformed JSON is rejected and a parse error is thrown. (See json.org for more information on proper JSON formatting.)

To avoid the manual building of JSON strings, use something like the JSON-java processor (from iNan’s comment) or other Java implementations listed on json.org.
