Question #6
A developer creates a Web service for his company's inventory service. He uses servlet container to deploy the web service and wants to enable basic authentication for all web service invocations. Where does the developer configure security requirements for the above case?
  1. A
    sun-jaxws.xml
  2. B
    web.xml
  3. C
    webservices.xml
  4. D
    domain.xml

Correct Answer:
B

Question #7
Choose the option that best describe the deployer's choices, when deploying an EJB that is also exposed as a RESTful web service using JAX-RS (Choose one):
  1. A
    The EJB can only be deployed to a web container, since RESTful access to the EJB requires a web container to support the HTTP interaction needed.
  2. B
    The EJB can be deployed to any EJB or web container that would support local references to the EJB from the JAX-RS runtime in the ejb container.
  3. C
    The EJB can be deployed to any EJB or web container that would support local references to the EJB from the JAX-RS runtime in the web container.
  4. D
    The EJB can be deployed to an EJB or web container that is visible to the JAX-RS runtime, even on an application server separate from the JAX-RS runtime,

Correct Answer:
C

Question #8
Given the JAX-RS root resource class fragment:

Choose the statement that best describes the configuration that would be required to support the access control constraint shown:
  1. A
    No further configuration is required - the JavaEE runtime will pick up the security constraint and configure the web container to match.
  2. B
    The developer will have to configure the web container to require authenticated access to the URLs corresponding to this resource, so the proper information can be propagated to the EJB container.
  3. C
    The developer will have to turn on authentication in the web container configuration file, so that all incoming requests are authenticated in order to be processed.
  4. D
    The developer will have to configure the web container to require authenticated access to the URLs corresponding to this resource, and then map web-tier roles to ejb-tier roles, since the JAX-RS and EJB runtimes cannot use the same set of roles.

Correct Answer:
B
