Re: JAXRS - POST

Redirecting to the users list...
Do you have a @GET annotated method producing application/json ?

RE: JAXRS - POST

Posted by Sergey Beryozkin <se...@iona.com>.

I'm sorry it takes so long to have the simple test working :-)
I will need to add a number of clarifications to the docs.

In the first case you need to use
"http://localhost:8081/SampleRestProject" only and the proxy will get

"helloWorld" and "customers" from HelloWorld interface and
HelloWorld.getCustomers.

Is it the POST method which is used in this case ? As it happens, in 2.2.5,
proxies can not handle empty POSTS (those which do not have any bodies in
the request) due to a minor restriction in HttpConduit. Which would likely
explain the exception. But WebClients can do it ok. Do you need to have
empty POSTs? If yes then I can update you on how to do them with proxies
even with 2.2.5 (a custom out inter ceptor will be needed), otherwise update
a method signature such that a body is actually passed or swicth back to
WebClients. 

In the 2nd case you're still combining WebClients and proxies. You can, if
you need, move from proxies to webclients and vice versa but you can not
combine them the way you do, with WebClients one is not programming against
interfaces like HelloWorld, the only interface is GET/POST/etc...

Just do

WebClient clnt = WebClient

.create("http://localhost:8081/SampleRestProject/helloWorld/customer");
                clnt.accept("application/json");
                Customers customers = clnt.get(Customers.class);

cheers, Sergey

RE: JAXRS - POST

Hi Sergey,

I moved the annotations to Interface and changed the conf. to use jaxrs
instead of http-binding.
I tried to access the service with this code:
		HelloWorld helloWorld =
JAXRSClientFactory.create("http://localhost:8081/SampleRestProject/helloWorld/customers",
HelloWorld.class);
		Customer customer = helloWorld.getCustomers();
		System.out.println(customer.getName());

I get this exception: java.lang.IllegalStateException: Already connected 

When tried with WebClient:
GET:
WebClient clnt = WebClient
				.create("http://localhost:8081/SampleRestProject/helloWorld/customer");
		clnt.accept("application/json");
		HelloWorld helloWorld = clnt.get(HelloWorld.class);
		helloWorld.getCustomers();
I get "org.apache.cxf.interceptor.Fault: Could not send Message."

POST Error:
".No message body reader found for class : interface com.tfs.pe.HelloWorld,
ContentType : application/json."

Thanks
Padmavathi V.

RE: JAXRS - POST

Posted by Sergey Beryozkin <sb...@progress.com>.

Hi-,

GET issue :

remove (you do not really need it) :
web.type("application/json");

and then do

Customer customer = web.get(Customer.class);

Same for POST...

I'm wondering, after looking through your code, perhaps you'd really like to use a proxy-based code ? If yes then you do not need to use a WebClient but use JAXRSClientFactory instead :

HelloService service = JAXRSClientFactory.createService(address);
Customers customers = service.getCustomers();
service.postCustomer(i, new Customer());

Also, the problem is that you have JAXRS annotations on the same method in the interface and in the impl, so it will not work. Perhaps just move all the annotations to the interface.

Finally, you do not use JAXRS properly on the server side, replace an http-binding import with the corresponding jaxrs one in your spring config...

Hope it helps, Sergey

Hi,

I'm not sure what is happening, can you please post a sample resource class containing this method, and capture what actually goes on the wire from the client ? 

is it GET or POST that you'd like a client to do ?
cheers, Sergey

Yes, it is annotated with @GET and @Produces.
