How to consume REST in Java

up vote2down votefavorite 2

Using Java tools, wscompile for RPC wsimport for Document etc.. I can use WSDL to generate the stub and Classes required to hit the SOAP Web Service. But I have no idea how I can do the same in REST. How can I get the Java classes required for hitting the REST Web Service. What is the way to hit the service anyway? Can anyone show me the way? java web-services rest share|improve this question asked Oct 16 '12 at 13:48 Mawia 895420

I don't want to hit the Web Service using URLs. I want to hit using my Java Classes. Is there a way? – Mawia Oct 18 '12 at 9:14

You can use HttpURLConnection. Below is an example of calling a RESTful service using the Java SE APIs including JAXB: String uri = "http://localhost:8080/CustomerService/rest/customers/1"; URL url = new URL(uri); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("GET"); connection.setRequestProperty("Accept", "application/xml"); JAXBContext jc = JAXBContext.newInstance(Customer.class); InputStream xml = connection.getInputStream(); Customer customer = (Customer) jc.createUnmarshaller().unmarshal(xml); connection.disconnect(); You can find the complete example here share|improve this answer answered Oct 16 '12 at 13:54 Anshu 5,4481823

	Do you mean I can get the Java Classes from WADL? –  Mawia Oct 18 '12 at 5:54
