A company is building a Java EE 5 purchase order processing system. This system will integrate with an external invoicing system as part of the purchase order approval process. A developer created a new client application to access the invoicing system using request-response, but a new service call is receiving errors every time it invokes the necessary Web service.

Which statement is true about the Body element of the SOAP reply message?

A. It must NOT contain any fault elements.

B. It will contain a fault element for each error.

C. It will contain exactly one fault element.

D. It must contain zero or one fault element.

E. It must contain an array of fault elements.

Which two statements are true about creating a Web service with JAX-WS? (Choose two.)

A. Stateless Web services must be created with HTTP servlet endpoints.

B. Creating the portable artifacts by hand is slow, but makes a service easier to maintain.

C. All Java-based endpoints share a common packaging model.

D. EJBs can serve as endpoints if hosted in a container with runtime and service support.

E. JAX-WS supports creating services from source and compiled code without a WSDL.

Which statement is true about JAX-WS dynamic invocation?

A. Dynamic invocation clients use RPC typed interfaces to invoke the Web service.

B. Dynamic invocation lets clients access a Web service without a WSDL.

C. Dynamic invocation clients are bound at design-time to a single Web service.

D. Dynamic invocation requires the client to statically configure the Web service proxy.

E. The dynamic proxies provide dynamic invocation in JAX-WS.

A purchase order Web service is designed to be synchronous, request-response, and HTTP- based. The existing service processes the request immediately. Because of new business requirements, the service can take up to ten days to perform a credit check before processing the order. Which two design changes need to be made? (Choose two.)

A. The client needs to use dynamic proxies instead of stubs.

B. The client needs to develop and deploy a Web service to accept callbacks.

C. The service only needs to change the WSDL from rpc-literal to document-literal.

D. The client and the service need to establish a mechanism to correlate the messages.

E. Given delays of up to ten days, a polling strategy is more efficient than callback.

Based on separation of concerns, which two are correctly implemented in the processing layer of a Web service? (Choose two.)

A. validation of XML documents

B. saving document contents in a database table

C. application of the business logic to the XML document

D. translation of incoming XML documents to their internal XML representations

E. a new SOAP message for exceptions during validation of XML

An organization has business logic implemented in EJB components. Current clients use container-managed, role-based security to access the business logic using RMI. Management has determined that the business logic must be made available to non-RMI clients using a Web service. Which container-managed Web service security mechanism must the development team use to allow Web service clients to use the current security model?

A. XKMS

B. XACML

C. XML Digital Signature

D. HTTP Basic Authentication

E. annotations mapped to the JAX-WS runtime

What are two features of a WSDL 1.1 document? (Choose two.)

A. Service defines a collection of related endpoints.

B. Service describes the message's payload using XML.

C. Service assigns an Internet address to a specific binding.

D. Porttype declares complex data types and elements used elsewhere.

E. Porttype elements are used to group a set of abstract operations.

F. Porttype defines a concrete protocol and data format specification.

An enterprise has a requirement to create a Web service to accept purchase orders. The order data contains some authorization information that is specific to each order (such as, who can access which parts of the order).

Keeping in mind future enhancements in types of orders that the enterprise needs to accept, which two design solutions provide the most flexibility? (Choose two .)

A. a Web service interface with one method per accepted XML document type for a purchase order

B. a procedure-style Web service method that lists all data elements and all possible access control options.

C. a document-style Web service method that accepts all types of XML documents representing purchase orders.

D. a Web service interface with one method for each combination of data elements and the access control options.
