Question

Why do I keep getting this message when trying to serialise an XML-string to JSON-string, when using Json-Lib.

Here is the code:

String jsonString = "<o><bool type=\"boolean\">true</bool>" +
                    "<int type=\"number\">1</int>" +
                    "<name type=\"string\">json</name></o>";
XMLSerializer xml = new XMLSerializer();
JSONObject jobject = (JSONObject) xml.read(jsonString);
System.out.println(jobject.toString(2));

Output is:

Sep 19, 2011 4:03:46 PM net.sf.json.xml.XMLSerializer getType
INFO: Using default type string
{
  "bool": true,
  "int": 1,
  "name": "json"
}

Why do I get this “INFO: Using default...” message? And, how can I get rid of it?

Answer 1

You are getting that message because your top level element o does not have a type. It’s just an INFO message, so you can ignore it. If you changed:

<o>

to:

<o type="object">

It should go away. But, it also shouldn’t matter.
