How to access the JSON reponse from a java client

[Dwijen Bhattacharjee]

Hi All,
I have very basic knowledge of webservice. Currently I am trying to convert the response of a Webservice as JSON . I follow the steps mentioned in the [url]http://www.marcusschiesser.de/?p=130 [/url] link. Now I am getting the response as a JSON object . But the problem I am facing is that how to access the response from a java client . I only know the use of OMElement to access the response from a webservice . so whenever I am trying to access the Webservice using OMElement from java clent its throwing an exception that "Unexpected chracter {.... expected <" . As per my understanding OMElement expects XML so it's expecting a response which started with < charecter , as my webservice's response is JSON .So it throws the exception. My question is how can i access the JSON response from java client ?? It will be better if you will post some code snippet.

Make use of the thoughtworks XStram API to convert the webservice response to JSON string.

Download this from http://xstream.codehaus.org/download.html

And the sample code will be like this.

 

MyRequestClass request = new MyRequestClass();
request.setXxxxxxxx();

MyResponseClass response = stub.getXxxxxx(request);

MyReturn return = response.get_return();

XStream xstream = new XStream(new JettisonMappedXmlDriver());
xstream.setMode(XStream.NO_REFERENCES);
xstream.omitField(MyReturnClass.class, "fieldToOmitInTheResponse");
xstream.alias("response", MyReturn.class);

String responseJSonString = xstream.toXML(response);

This link is also useful.
