I have looked around on the web but can seem to get this working. I have a web service where i am trying to read JSON but i keep getting an error when i create the XStream object. here is the code i have and the error

```
 public static InputDTO inputFromJson(HttpServletRequest request) throws IOException {
        logger.debug("in inputfromjson");
        XStream xstreamJson = new XStream(new JettisonMappedXmlDriver()); //this is where the code starts failing
        logger.debug("after xstreamjson create");
        xstreamJson.alias("tz", String.class);
        InputDTO inputDTO = null;
        try (InputStream is = request.getInputStream())
        {
            Object dto = xstreamJson.fromXML(is);
            if (dto instanceof InputDTO) {
                inputDTO = (InputDTO)dto;
            }
        }
        logger.debug(inputDTO);
        return inputDTO;

    }

```

The error i am getting is 

```
 java.lang.ClassNotFoundException: org.codehaus.jettison.mapped.Configuration
at       org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1680)

at com.thoughtworks.xstream.io.json.JettisonMappedXmlDriver.<init>(JettisonMappedXmlDriver.java:48)
at com.homedepot.week3.XMLReader.inputFromJson(XMLReader.java:81)

```

I have read that i need to import the org.codehaus.jettison.json.\*; but that doesn't seem to fix anything. Could someone please help with this? I'm sure its something simple.

Thanks!
