How can I access a Restful webservice using servlet?

Is there any way I can access 开发者_StackOverflowRESTful webservice using a servlet. I dont want to use Jersey client?

EDIT: How can I pass object in the url and make sure that marshalling/unmarshalling is done properly?

You can use the commons-httpclient library (http://hc.apache.org/httpcomponents-client-ga/) to make a request to your REST service, and gson (http://code.google.com/p/google-gson/) to serialize/deserialize java objects to JSON

You could code your own HTTP requests e.g. using HTTPURLConnection. Here you can set the request method and change the URL or/and body as appropiate e.g.

   URL url = new URL("http://www.example.com/resource");
   HttpURLConnection connection = (HttpURLConnection) url.openConnection();
   connection.setRequestMethod("GET");
  // etc

This way you're just using the standard java.net API.

You don't need to use jersey client, it's just a URL, you can use:

new URL("http://locationofservice").openConnection();
