Print Jersey JSON in Unit Testing

Question

Is there any plain way - to print a JAXB annotated instance - in JSON format (as exactly jersey will print in AS) - while running unit testing - without any embedded server launched? I can run and see in XML with JAXBContext, Marshaller, and so on. Is there any example for JSON? I found it. It's similar to JAXB. With Jersey API ``` final JSONJAXBContext context = new JSONJAXBContext(...); final JSONMarshaller marshaller = context.createJSONMarshaller(); marshaller.marshallToJSON(...); final JSONUnmarshaller unmarshaller = context.createJSONUnmarshaller(); final T unmarshalled = unmarshaller.unmarshalJAXBElementFromJSON( ..., T.class).getValue(); ``` for Maven ``` com.sun.jersey jersey-json test ```

Accepted Answer

It is possible:

```
...
StringWriter writer = new StringWriter();
marshaller.marshallToJSON(objectToMarshall, writer)
logger.debug(writer.toString());
...
```

You can use an `StringWriter` to take the `String` representation of the marshalled JSON output.
