A developer is asked to consult on a Web services project and assist the team with a good design approach on a new project. The team members disagree on whether to use WSDL or Java first. Several members are skilled with XML and see a schema and WSDL as the correct place to start. The team has also learned the deadline for this project has been moved up and another team plans to reuse their code. Which statement is true about the proper course of action to take in this situation?

• A.  WSDL should be used first because it will make the code easier to reuse for the other team.
• B.  Java should be used first because it is a strongly typed language and will result in a robust WSDL.
• C.  Java should be used first because it is often the fastest and easiest approach.
• D.  WSDL should be used first because the team knows XML Schema.

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.

  <wsa:Action>http://example.com/action/process</wsa:Action>
  <wsa:ReplyTo>
  <wsa:Address>http://example.com/service</wsa:Address>
  <wsa:ReplyTo>
  </s11:Header>
• B.  <s11:Header>
  <wsa:Action>http://example.com/action/process</wsa:Action>
  <wsa:ReplyTo>
  <wsa:Address>http://example.com/responseprocessor</wsa:Address>

A developer is creating a web service endpoint using a stateless session EJB.

What must be the value for <ejb-link> for the above service in the webservices.xml ? (Choose one)

• A.  Counter
• B.  CounterEJB
• C.  CounterService
• D.  CounterPort

Given the two classes:

Choose the option that best evaluates the example:

• A.  This is a valid example of two EJBs used as JAX-RS resources, one a root resource and the other a subresource.
• B.  This is an invalid example, because the JAX-specification only allows root resource types to also be EJBs.
• C.  This is an invalid example, because EJBs that are to be used as JAX-RS subresources have to match the type of EJB of their "parent" resource.
• D.  This is an invalid example, because singleton EJBs used as JAX-RS resources must explicitly state what locking strategy they will require.

A company is building a customer relationship management system that is to be deployed on a customer's network, and they want software functions to be reused and combined in different modules in the system. The Director of Technology has determined that the new system should utilize both Web services and a Service Oriented Architecture (SOA). Which two statements about Web services in an SOA are correct? (Choose two.)

• A.  SOA is a way to design a system and Web services are a possible implementation.
• B.  A Web service must publish itself to a UDDI registry to become part of an SOA.
• C.  SOA and Web services both use the HTTP protocol at the transport layer.
• D.  SOA is used for stateless invocations, and Web services for stateful invocations.
• E.  SOA emphasizes the concept of service encapsulation and Web services fulfill a service contract.
• F.  A Web service must be discovered from a UDDI registry in an SO
