Subresource for target class has no jax-rs annotations - web-services

Question

I am trying to call a webservice method via a proxy but I have got an error message that says: "Subresource for target class has no jax-rs annotations.: org.jboss.resteasy.core.ServerResponse"
Here is my server class
#Path("/authorizationCheck")
public class AuthorizationRestService implements AuthorizationService {
#Override
#Path("/webserviceTest")
public Response webserviceTest(){
TestDTO x = new TestDTO();
x.setFieldOne("ffff");
x.setFieldTwo("gggg");
Response res = Response.ok(x).build();
return res;
}
}
with a an interface like this
#Path("/authorizationCheck")
public interface AuthorizationService {
#POST
#Path("/webserviceTest")
public Response webserviceTest();
}
and my return object wrapped in response
#XmlRootElement
#XmlAccessorType(XmlAccessType.FIELD)
public class TestDTO {
private String fieldOne;
private String fieldTwo;
public String getFieldOne() {
return fieldOne;
}
public void setFieldOne(String fieldOne) {
this.fieldOne = fieldOne;
}
public String getFieldTwo() {
return fieldTwo;
}
public void setFieldTwo(String fieldTwo) {
this.fieldTwo = fieldTwo;
}
}
and finally my client class
#Stateful
#Scope(ScopeType.CONVERSATION)
#Name("authorizationCheckService")
public class AuthorizationCheckService {
public void testWebservice(){
RegisterBuiltin.register(ResteasyProviderFactory.getInstance());
AuthorizationService proxy =
ProxyFactory.create(AuthorizationService.class,
ApplicationConfig.WORKFLOWSERVER_URL + "services/authorizationCheck/webserviceTest");
Response response = proxy.webserviceTest();
return;
}
}
what I am doing wrong here , any help will be appreciated.

Answer 1

You have two annotations with webserviceTest() which are #POST and #Path.
Repeat BOTH the annotations in over ridden method in implemented class. That means add the #POST annotation to webserviceTest() method.
It should work then !
And here is the reason why it din't work.. without proper annotations in implementing class.
Why java classes do not inherit annotations from implemented interfaces?

Answer 2

You can remove the #Path annotations on the implementation class and concrete method, and only annotate your interfaces, like this:
public class AuthorizationRestService implements AuthorizationService {
#Override
public Response webserviceTest(){
TestDTO x = new TestDTO();
x.setFieldOne("ffff");
x.setFieldTwo("gggg");
Response res = Response.ok(x).build();
return res;
}
}
Note: don't forget #Produces on your interface method to define your MIME type, such as MediaType.APPLICATION_XML
#Path("/authorizationCheck")
public interface AuthorizationService {
#POST
#Path("/webserviceTest")
#Produces(MediaType.APPLICATION_XML)
public Response webserviceTest();
}

Answer 3

I changed like this
#Path("/authorizationCheck")
public class AuthorizationRestService implements AuthorizationService {
#Override
#Path("/webserviceTest")
#POST
#Produces(MediaType.APPLICATION_XML)
public Response webserviceTest(){
TestDTO x = new TestDTO();
x.setFieldOne("ffff");
x.setFieldTwo("gggg");
Response res = Response.ok(x).build();
return res;
}
}
My Test Client is different
public class CustomerResourceTest
{
#Test
public void testCustomerResource() throws Exception
{
URL postUrl = new URL("http://localhost:9095/authorizationCheck/webserviceTest");
HttpURLConnection connection = (HttpURLConnection) postUrl.openConnection();
connection.setRequestMethod("POST");
System.out.println("Content-Type: " + connection.getContentType());
BufferedReader reader = new BufferedReader(new
InputStreamReader(connection.getInputStream()));
String line = reader.readLine();
while (line != null)
{
System.out.println(line);
line = reader.readLine();
}
Assert.assertEquals(HttpURLConnection.HTTP_OK, connection.getResponseCode());
connection.disconnect();
return;
}
}
It produced output
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><testDTO><fieldOne>ffff</fieldOne><fieldTwo>gggg</fieldTwo></testDTO>
Had to add following dependency also
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.2.11</version>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jaxb-provider</artifactId>
<version>2.2.0.GA</version>
</dependency>
Tried your code.
public void testCustomerResource() throws Exception
{
RegisterBuiltin.register(ResteasyProviderFactory.getInstance());
AuthorizationService proxy =
ProxyFactory.create(AuthorizationService.class,"http://localhost:9095/");
ClientResponse response = (ClientResponse) proxy.webserviceTest();
String str = (String)response.getEntity(String.class);
System.out.println(str);
return;
}
Produced same output
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><testDTO><fieldOne>ffff</fieldOne><fieldTwo>gggg</fieldTwo></testDTO>
Note how I created proxy. I had only base url **http://localhost:9095/**. I did not mention resources authorizationCheck/webserviceTest in that. This is different from how you coded.
