Problem with XStream Marshalling to return xml and json
- by MiKu
When i use 
new XStream().toXml(someObject);
it returns following xml...
<response>
        <status>SUCCESS</status>
        <isOwnershipVerified class="boolean">false</isOwnershipVerified>
</response>
and, when i use
new XStream(new JsonHierarchicalStreamDriver()).toXml(someObject);
it returns following json...
{"response": {
  "status": "SUCCESS",
  "isOwnershipVerified": {
    "@class": "boolean""false"}
}}
Now, since i want to get rid of class attribute altogether (read it not to alias it with anything else, but to remove it) i use following code.
    XStream xStream = new XStream();
    StringWriter writer = new StringWriter();
    xStream.marshal(this, new PrettyPrintWriter(writer) {
        @Override
        public void addAttribute(final String key, final String value)
        {
            if (!key.equals("class"))
            {
                super.addAttribute(key, value);
            }
        }
    });
    return writer.toString();
which gives follwing xml...
<response>
        <status>SUCCESS</status>
        <isOwnershipVerified>false</isOwnershipVerified>
</response>
but, when i pass new JsonHierarchicalStreamDriver() while xStream object creation above, it does NOT return json. it returns the same xml shown above. 
What is wrong going on here?
Thanks in advance...
