Oracle Java Platform, Enterprise Edition 6 Web Services Developer Set 1

1.

A developer is asked to determine which Web services approach is correct for a new project. A SOAP-based Web service must be created and deployed in an environment where many customers will use it. These customers will be responsible for developing their own clients using different frameworks, based on the published WSDL. Which approach is correct to use first in this situation? (Choose one)

Java, because the WSDL generated later will be more accurate WSDL, because the service and customers can benefit from the strongly typed schema Java, because the service must be efficient to support many customers WSDL, because tools allow existing classes to be easily mapped without modification

2.

Which of the following can an EJB-based web service endpoint may NOT be able to use ?

Servlet sessions Java EE 6 declarative security container-managed transactions dependency injection

3.

A developer is creating a web service endpoint using a stateless session EJB. What must be the value for for the above service in the webservices.xml ? (Choose one)

CounterEJB Counter CounterService CounterPort

4.

Given the class: Choose the option that describes what would happen if this class were deployed (Choose one):

Any HTTP GET or POST request with the URL "/resource" would result in a call to getName(). Any HTTP GET or POST request with URLs that begin with "/resource" would result in a call to getName(). A runtime error would result, since a method cannot be responsible for both GET and POST requests. A compile error would result, since a method cannot be responsible for both GET and POST requests.

5.

Which of the following is NOT true about configuring handlers on a Web Service endpoint? (Choose one)

EE container automatically processes the handlers packaged in the application and configures it on the applicable endpoint Handlers can be configured using @HandlerChain annotation on endpoints configured with @WebService Handlers can be configured using @HandlerChain annotation on endpoints configured with@WebServiceProvider Handlers can be configured for endpoints in the deployment descriptor (webservices.xml)

6.

Choose the JAX-RS type that is used to produce URLs to resources, given the resource class, to incorporate into resource responses (Choose one):

UriBuilder UriInfo UriMapper Producer

7.

If you are developing a Web Service starting from WSDL 1.1, how would you declare in wsdl that the Web Service requires the use of Addressing in a standard and interoperable way.

Declare a policy as and attach it the corresponding wsdl:portType so that it applies to all the wsdl:operations in its scope. Declare a policy as and attach it the corresponding wsdl:binding so that it applies to all the wsdl:operations in its scope. Declare a policy as and attach it the corresponding wsdl:binding so that it applies to all the wsdl:operations in its scope. Declare a policy as and attach it the corresponding wsdl:service so that it applies to all the wsdl:ports in the service scope.

8.

In the following situation, Client C sends a SOAP request to Service S and the response is to be processed by a third party response processor R. Which of the following SOAP headers in the request message convey the intention? Assume the endpoint reference of Service S is

http://example.com/action/process http://www.w3.org/2005/08/addressing/none http://example.com/action/process http://www.w3.org/2005/08/addressing/anonymous http://example.com/action/process http://example.com/responseprocessor http://example.com/action/process http://example.com/service

9.

What is an advantage of enabling Addressing feature on an endpoint?

Addressing ensures reliable transfer of messages between client address and the service address. Addressing ensures the message exchanges between the client and service are properly secured. Addressing enables the optimization of messages exchanged between the client and the service. Addressing provides transport-neutral way to address the endpoints and messages.

10.

Which statement is true about StAX?

StAX provides client parsing control with memory usage similar to DOM. StAX allows clients to start, pause and resume the parsing process. StAX is the only XML parsing approach supported with JAX-WS. StAX is a more efficient version of SAX, based on newer XML technology.
