New to webservice

[Kacee Saxena]

Dear All,

I am new to Web Service. I want to create a RESTful webservice and a client to access the service.

I have few basic queries:

1) Is webservice client for a RESTful and SOAP service different ? I think client can be generic and should be able to access any type of web service. Please reply if this is correct.

2) For RESTful services,(JAX-RS) API is available and a reference implementation - Jersey. I want to create the web service without using Jersey implementation as I dont want to take overhead of Jersey libraries. Is it possible?

Please refer a minimal basic RESTful web service implementation and a client.

Any help would be highly appreciated.

Thanks,
Kacee

Sure, the client can be generic if you make it so. But SOAP and REST are different approaches, and the client would have to have code that implements both.

For RESTful services,(JAX-RS) API is available and a reference implementation - Jersey. I want to create the web service without using Jersey implementation as I dont want to take overhead of Jersey libraries. Is it possible?

Any HTTP client library (like Apache HttpClient) would do, although it wouldn't be as convenient as using a dedicated JAX-RS client library. All Jersey libraries together amount to less than 4 MB in size; is that what you mean by "overhead"? What kind of scenario are you envisioning where that would be a problem?

I want to create a WebService and a client. I have a specification to use only basic APIs and refrain from using any reference implementation. Application itself is very big and we are adding different modules to it. Web Service impementation is another feature we are adding to it.

Hence I want to use only minimal set of external libraries. In short, I want to create a "hello world" web service and a client using REST for my understanding first. Later on , i will develop a full fledge service as per requirements.

Please post a link or guide me to a "hello world" implementation of REST based webservice & client.

Thanks,
Kacee

For the server side, Jersey comes with a couple of HelloWorld-type example services.

The client side would be nothing more than accessing an URL; the java.net.HttpURLConnection class can do that.
