I\'m currently looking for ways to create automated tests for a JAX-RS (Java API for RESTful Web Services) based web service.
I basically need a way to send it cert
I use Apache's HTTPClient (http://hc.apache.org/) to call Restful Services. The HTTP Client library allows you to easily perform get, post or whatever other operation you need. If your service uses JAXB for xml binding, you can create a JAXBContext to serialize and deserialize inputs and outputs from the HTTP request.
