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

Answer 1

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.
