Java web service - framework for parsing response text

Question

I am writing a java application which invokes a web service and uses its response text. (i.e.) it invokes a URL like http://web-server.com/item/3455

That URL would return a response text (string) like "nexus".

For implementing the above functionality, is there any readily available framework that we can make use of? Or should I code the functionality from scratch.

Thanks.

Even if the API is not strictly RESTful, you can use spring-web's RestTemplate like so:

RestTemplate restTemplate = new RestTemplate();
String response = restTemplate.getForObject("http://web-server.com/item/3455", String.class);

thanks. that looks really cool, I am just wondering if there could be a lighter option (a smaller framework). – saravana_pc Jul 17 '12 at 14:15
Could you provide the maven dependency for this jar? many thanks. – saravana_pc Jul 17 '12 at 14:31
If you're using Maven, it's in the central repo (http://search.maven.org/#search|ga|1|spring-web). – WA Hunt Jul 17 '12 at 14:48
The lightest option per my experience is to use apache http client to make a request and capture response, and dont bother whether its webservice/restful or not. – techuser soma Jul 21 '12 at 17:54

Based on url, it seems you are doing REST call. You may use HTTPURLConnection API.

thanks. Could we use this for non-rest web services as well? For example, if the URL is like http://web-server.com/item?id=3455 – saravana_pc Jul 17 '12 at 14:13

All you need is a simple HTTP client to do what you're talking about. The HttpClient project from Apache is a popular choice and would certainly work for what you're trying to do.
